Aikyam-Lab/Synoptic-Bench huggingface dataset:
Mid level high pressure will remain centered over the Desert Southwest over the next few days, placing Deep South Texas within the southeaster periphery of ridging aloft. Heading into the weekend, model guidance indicates there may be a slight uptick in precipitation across portions of the region as a weak mid level trough translates towards the Texas Coast. The highest moisture content is expected to reside along and east of I-69E, and may result in pockets of locally heavy rain within robust showers or thunderstorms. (18Z TAFS) VFR will prevail through the forecast period at all TAF sites as the region remains under the influence of high pressure.
Lows tonight in the low to mid 70s expected, with the warmer readings along and north of I-20.
/NEW/ /Through Friday/ Today and tomorrow will feature the hottest temperatures of the week as a 598-600 dam mid-level ridge remains stationed over New Mexico.
305 PM EDT Thu Aug 7 2025 - Very isolated storms possible through the early evening hours; most areas will remain dry - Patchy fog possible again tonight - Dry through the weekend, with gradually warmer and more humid conditions expected - Shower and thunderstorm chances return next work week. Aloft, dry air and subsidence will be in play, as a strong upper ridge, orgininating from an upper high over the American southwest will be passing across the region through the weekend. Southerly flow will keep warm and humid air in place over Indiana through the weekend, resulting in highs in the lower 90s and lows in the upper 60s.
Tonight's temperatures will generally be in the mid 60s across the lowlands, ranging into the mid 50s northeast mountains.
809 PM EDT Sun Jun 30 2024 A cold front will move across the mid-atlantic region, with scattered showers and thunderstorms through this evening.
625 PM CDT Sun Jun 30 2024 Scattered thunderstorms will end this evening as slightly cooler and drier air moves into the Mid-South.
658 PM CDT Sun Jun 30 2024 (Tonight) After the ongoing medium-high chances of showers/storms (40-75%) subside in the wake of a cold front later this evening, dry conditions are forecast to prevail overnight throughout the TN Valley.
846 PM EDT Sun Jun 30 2024 A cold front will move through Monday bringing a reprieve from the heat and humidity into mid week. Pre frontal trough lighting up this afternoon just to the northwest poised to move into the area in the next little bit as more sporadic convection is slowly developing elsewhere. Its worth noting the higher pops overall tonight represent the possibility convection fills in somewhat between two expected pushes. Highlights: *Unseasonably cooler and drier through the period Confidence: *Moderate to High Details: A rather unseasonably cooler and drier air mass is expected to prevail through the period as high pressure builds in from the north behind a departing cold front to the south.
Have a great night! Ridging will begin to build over the area on Monday, leading to clearing skies, especially by the afternoon. Temperatures will be much cooler than today, mainly in the 70s.
(Rest of tonight) A sfc front will make its way south through the area tonight, bringing drier and slightly cooler conditions to the area in its wake. Otherwise, enjoy the cooler and less humid air tonight while it lasts, with lows falling into the mid to upper 60s.
636 PM CDT Sun Jun 30 2024 (Tonight through Monday night) A tropical disturbance in the southern Bay of Campeche could become a Tropical Cyclone before making landfall in Mexico. The NHC has an 80% chance for tropical cyclone development in the next 48 hours. The dominant feature for the short term period will be an upper- level ridge over North Texas, that will slowly shift east through the period.
A drier and much warmer pattern will set up by the end of the work week. Areas expected to receive the highest rainfall amounts (upward of half an inch) by the end of the night include Boundary County, northern Pend Orielle County, and northern Bonner County. Our insulating blanket of clouds will clear out overnight, and temperatures will drop into the 40s and 50s - considerably cooler than last night.
656 PM MDT Sun Jun 30 2024 - Warmer today, with scattered afternoon storms.
811 PM EDT Sun Jun 30 2024 High pressure and a cooler, drier airmass will remain in place across the region through Monday. Lows tonight will be mostly in the low to mid 50s with even some upper 40s possible in outlying areas.
531 PM EDT Sun Jun 30 2024 Building high pressure will return comfortable dry weather for the first half of the week before an unsettled pattern takes hold to close out the week. KEY MESSAGES: - Cooler and drier weather expected tonight behind an exiting cold front ------------------------------------------------------------------- The latest mesoanalysis shows a cold front extending from eastern PA through northern WV. We then finally get a push of drier air (dew points in the 40s upstream) as high pressure builds across the Great Lakes and reinforces northerly flow in the wake of the boundary. Still, overnight lows will be refreshing dipping into the 50s (even 60-80% chance of upper 40s in the ridges and north of I-80).
Current temperatures are in the upper 70s to low 80s with dew points in the low to upper 70s. Analysis charts show a mid level trough to the northeast over the eastern CONUS with a mid/upper level ridge building over the central CONUS. Overnight low temperatures are forecast to drop into the low to upper 70s. A ridge of high pressure will remain just north of the local Atlantic waters, with predominant south to southeast breezes increasing 10-12 KT each day behind the sea breeze.
This is because there is an inverted trough moving through the easterlies which is providing us the moisture and lift needed for convection. This hour, looking at infrared satellite imagery coupled with KBYX/KAMX radars, it appears the trough axis is roughly located between Andros Island and South Florida. The trough axis will continue to slowly push west overnight and expecting another round to develop. As this trough pushes across the area, we will see northeast to east winds become more east to southeast towards dawn.
1052 PM EDT Sun Jun 30 2024 A cold front continues to move through the region tonight.
921 PM EDT Sun Jun 30 2024 A cold front currently moving through the region this evening is expected to bring slightly cooler and drier conditions to start off the work week, but building high pressure will allow the return of temperatures near the century mark by mid to late week. Upper trough centered over the northeast CONUS will shift off the coast by evening. The strong upper ridge over the southern Plains will begin to build back east. Area in general cold advection so, max temperatures should be significantly cooler than previous days. in the 85 to 90 degree range with lingering cloudiness into into the afternoon and cooler at night with lows into the mid to upper 60s.
Ridging will begin to build over the area on Monday, leading to clearing skies, especially by the afternoon. Temperatures will be much cooler than today, mainly in the 70s.
644 PM EDT Sun Jun 30 2024 - Cooler and less humid conditions continue into tomorrow as high pressure ensures a dry forecast.
/NEW/ /Tonight through Monday Night/ Hot, humid, and generally precipitation free conditions will prevail through the early part of the week with near record high minimum temperatures in the lower 80s at night and afternoon highs at or above 100 degrees on Monday. An upper level trough will slide through the Plains Days 6-7, with a cold front likely knocking highs down into the 90s and bringing low storm chances. Relief may be on the horizon, as there are indications the ridge will weaken late this week as a longwave trough/upper low moves into the Central CONUS.
This has kept conditions much cooler up there with temperatures reaching the lower to mid 70s in the Oklahoma Panhandle and some lower 80s in northern Texas Panhandle. Residual cloud debris has left conditions cooler to the north of this line, whereas along and south temperatures have warmed into the lower 90s. Global models are in agreement that the mid level ridge should once again meander its way toward the region, but remain centered just to our east. To our west, an upper trough will approach, bringing showers and storms to New Mexico. By late afternoon, several models and hi-res CAMs indicate that they could meander across the state line into my western forecast area, especially as the low level jet begins to kick in during the evening hours.
These have mostly subsided, but strong winds with isolated high terrain showers and thunderstorms (10-20% chance) are anticipated to return tomorrow as the upper level trough swings east.
Only a few more showers and storms across the forecast area as cold front approaches from the NW. If any fog forms it will likely be south and eastern parts of the forecast area ahead of cold front. Cooler and drier air moving in tonight. The cold front passes through tonight, brining cooler and drier air into the region.
741 PM EDT Sun Jun 30 2024 A cold front crosses the area today.
Northwesterly flow that is bringing in cooler temperatures is expected to last through midweek followed by a high pressure system moving in behind towards southern California, which will bring quieter conditions and warmer temperatures. Cooler air from the front is expected to drop overnight temperatures into the 40s and 50s.
1035 PM EDT Sun Jun 30 2024 High pressure and a cooler, drier airmass will remain in place across the region through Monday. Lows tonight will be mostly in the low to mid 50s.
637 PM CDT Sun Jun 30 2024 (This evening through Monday) Isolated to widely scattered showers and thunderstorms remain possible through early evening along the quasi-stationary front as it slowly shifts north of I-40 and transitions as a warm front late tonight. The 599 dam high pressure ridge observed over north Texas this morning weakens slightly while sliding to the east as a trough departs the Pacific Northwest deepens over the northern high plains tomorrow.
/CME/ Tonight and tomorrow: A few showers and storms could linger past sunset tonight, as a surface cold front pushes south across the area. Heat makes a return mid week with upper ridging continuing to build eastward.
836 PM EDT Sun Jun 30 2024 A cold front is moving across the Mid-atlantic region. Winds will become northerly overnight, introducing cooler, less humid weather for Monday.
654 PM CDT Sun Jun 30 2024 Tonight and tomorrow: A few showers and storms could linger past sunset tonight, as a surface cold front pushes south across the area. Heat makes a return mid week with upper ridging continuing to build eastward.
705 PM EDT Sun Jun 30 2024 A cold front will push through the area tonight into Monday.
910 PM EDT Sun Jun 30 2024 A cold front will push through this evening.
834 PM EDT Sun Jun 30 2024 Cool and comfortable tonight in the wake of a cold front.
325 AM EDT Mon Jul 1 2024 High pressure and a cooler, drier airmass will remain in place across the region today. It will be cooler and drier. Ridging will still extend back into the middle Ohio Valley. Meanwhile, mid level ridging will build into the Great Lakes and Ohio Valley. Some high clouds will filter through the mid level ridge, allowing skies to vary between mostly clear and partly cloudy.
High pressure will build far offshore tonight into Monday maintaining onshore flow keeping temperatures near normal for the next few days. High pressure shifts over the region late in the week about a sharp warm up starting around the Independence Day holiday and continuing through the weekend.
(Today and tonight) Persistence is the name of the game today as another hot and dry day is expected across the region as the upper-level ridge slowly drifts towards the ArkLaTex region. Weather won't be too different overnight either with low temperatures ranging from the low to mid 70s on the Caprock and mid to upper 70s east of the Caprock escarpment although southerly breezes will remain around 10-15 mph.
Water vapor imagery highlights a ridge-trough couplet over the CONUS, northwest of a series of TUTT cells stretching west- southwest from the central Atlantic to the Gulf of Mexico. Consequently, the low-level ridge is fractured into a broad and sloppy trough near the Keys. The low-level cyclonic curvature in the Straits will spread to the northwest today and tonight.
300 AM EDT Mon Jul 1 2024 High pressure builds in from the Great Lakes today, bringing less humid air.
The center of the upper- level ridge is located further eastward today, compared to yesterday. Therefore, high temperatures should be a few degrees cooler than the past few days but should still reach the low 100s.
252 AM EDT Mon Jul 1 2024 A cold front will push through the area very early today.
151 AM EDT Mon Jul 1 2024 High pressure and a cooler, drier airmass will remain in place across the region through Monday. Lows tonight will be mostly in the low to mid 50s.
140 AM MDT Mon Jul 1 2024 - A cold front today brings cooler temperatures and rain chances, mainly across the northern half of Wyoming. A cold front moves through the area today. As a result, it will be noticeably cooler, especially compared to the highs yesterday that were in the 90s for many locations, with a few 100s noted. The best chances continue across the northern part of the state through the day as broad trough influences the area. Precipitation continues across the north tonight as the broad trough remains in place.
401 AM EDT Mon Jul 1 2024 High pressure builds in today with dry conditions expected for the first half of the week.
Northwesterly flow that is bringing in cooler temperatures is expected to last through midweek followed by a high pressure system moving in behind towards southern California, which will bring quieter conditions and warmer temperatures. Northwesterly flow that is bringing in cooler temperatures is expected to last through midweek followed by a high pressure system moving in behind towards southern California, which will bring quieter conditions and warmer temperatures. Cooler air from the front is expected to drop overnight temperatures into the 40s and 50s.
1246 AM EDT Mon Jul 1 2024 High pressure will provide dry and comfortable weather for the first half of the week before an unsettled pattern takes hold to close out the week. Slow height rises aloft and building high pressure will provide dry and comfortable conditions with lots of sunshine.
NBM populated dewpoints on the high side of the guidance envelope and given the tendency to keep somewhat higher dewpoints last week, we will go with keeping the NBM's higher dewpoints at least through the central third of the area.
1155 PM EDT Sun Jun 30 2024 - Cooler and less humid conditions continue into tomorrow as high pressure ensures a dry forecast.
1136 PM CDT Sun Jun 30 2024 (Rest of tonight) A sfc front will make its way south through the area tonight, bringing drier and slightly cooler conditions to the area in its wake. Otherwise, enjoy the cooler and less humid air tonight while it lasts, with lows falling into the mid to upper 60s.
1232 AM EDT Mon Jul 1 2024 A cold front will clear our region overnight.
103 AM CDT Mon Jul 1 2024 Tonight and tomorrow: A few showers and storms could linger past sunset tonight, as a surface cold front pushes south across the area. Heat makes a return mid week with upper ridging continuing to build eastward.
Currently at the surface, the sub-tropical ridge of high pressure centered over the Atlantic is extending across central Florida, keeping light and generally southerly/southeasterly flow in place across the forecast area.
325 AM EDT Mon Jul 1 2024 Cooler and drier air works into the region today behind a departing cold front.
123 AM EDT Mon Jul 1 2024 Cool and comfortable tonight in the wake of a cold front.
409 AM EDT Mon Jul 1 2024 High pressure builds in today with dry conditions expected for the first half of the week.
235 AM EDT Mon Jul 1 2024 A cold front will push through the area very early today.
Near to slightly above normal temperatures will lead-off this week with today's daytime highs in the low-80s for Sierra communities and low to mid 90s for western Nevada valleys. An upper, eastern Pacific ridge will gradually amplify as it translates eastward towards the western states, promoting a steady warming trend this week and into the weekend.
(The rest of tonight) High pressure centered over the upper Midwest ridging into the Southern Plains this evening resulting in slightly lower dewpoints across the northern areas, which saw some relief from the heat this afternoon.
Dewpoints remain in the lower 70s (with air temperatures in the lower 80s) as of 07z. Still, with high pressure building in from the north, a drier post frontal air mass will work its way into the area today as seen by dewpoints falling into the upper 50s (yes, you read that right!) by mid/late afternoon.
Upper level ridging currently over the region will get pushed east today as a trough approaches from the west.
124 AM EDT Mon Jul 1 2024 High pressure builds in from the Great Lakes today, bringing less humid air.
152 AM EDT Mon Jul 1 2024 A cold front will push through the area very early today.
1034 PM CDT Sun Jun 30 2024 (This evening through Monday) Isolated to widely scattered showers and thunderstorms remain possible through early evening along the quasi-stationary front as it slowly shifts north of I-40 and transitions as a warm front late tonight. The 599 dam high pressure ridge observed over north Texas this morning weakens slightly while sliding to the east as a trough departs the Pacific Northwest deepens over the northern high plains tomorrow.
1232 AM PDT Mon Jul 1 2024 A trough of low pressure will pass across Northern Nevada today.
354 AM EDT Mon Jul 1 2024 High pressure will provide dry and comfortable weather for the first half of the week before an unsettled pattern takes hold to close out the week. ------------------------------------------------------------------- Slow height rises aloft and building high pressure will provide dry and comfortable conditions with lots of sunshine.
1224 AM CDT Mon Jul 1 2024 (The rest of tonight) High pressure centered over the upper Midwest ridging into the Southern Plains this evening resulting in slightly lower dewpoints across the northern areas, which saw some relief from the heat this afternoon.
Strong ridging aloft will allow temperatures to rise into the mid-upper 90s for most locations across eastern OK and west-central AR. As such, another dangerously hot and humid day will transpire across most of the forecast area today, with the exception being in the higher terrain areas in northwest AR and southeast OK.
1216 AM CDT Mon Jul 1 2024 (Tonight through Monday night) A tropical disturbance in the southern Bay of Campeche could become a Tropical Cyclone before making landfall in Mexico. The NHC has an 80% chance for tropical cyclone development in the next 48 hours. The dominant feature for the short term period will be an upper- level ridge over North Texas, that will slowly shift east through the period.
Temperatures warm back into the upper 80s to low 90s starting Tuesday ahead of another cold front passage, which will drop temperatures slightly into the mid-to-low 80s for the remainder of the week.
A ridge of high pressure sitting over the coastal waters will keep light south and southeast flow in place today and Tuesday, turning onshore near the coast each afternoon with the seabreeze.
As warm air advection begins aloft on the back side of the departing high pressure, clouds will begin to move in through the evening hours. Rain will arrive after midnight tonight as a low pressure system passes to our northwest. Between the two rounds of heavier rainfall, a widespread 1-2 inches of rainfall with local amounts up to 2-3 is possible, which may create some flooding concerns for lowland areas, river rises, and/or urban flooding if the higher rainfall swaths cover the same areas.
553 AM EDT Mon Jul 1 2024 High pressure builds in today with dry conditions expected for the first half of the week.
We do see a northerly flow across the area, so the mean trough is already through. We could see some isolated to scattered convection in the southeast along the edge of the trough but ahead of the front.
414 AM MDT Mon Jul 1 2024 - A cold front today brings cooler temperatures and rain chances, mainly across the northern half of Wyoming. A cold front moves through the area today. As a result, it will be noticeably cooler, especially compared to the highs yesterday that were in the 90s for many locations, with a few 100s noted. The best chances continue across the northern part of the state through the day as broad trough influences the area. Precipitation continues across the north tonight as the broad trough remains in place.
The upper ridge remains in control across the southern Plains today, but nudges eastward some for Tuesday. A more eastward ridge center allows southwesterly flow to strengthen the low level thermal ridge some, ticking high temperatures up a few degrees for Tuesday.
623 AM CDT Mon Jul 1 2024 (Today through Tuesday) Cold front has pushed south of Middle Tennessee this morning with cooler and drier air gradually filtering in from the north. Today will feel quite un-July-like thanks to this cooler and drier airmass, with highs only expected to reach the upper 70s to the mid 80s - which is up to 5 degrees below normal for early July. Unfortunately, this nice weather will not last long as a strong upper level ridge with 500mb heights near 596dm shifts eastward and centers itself across the state on Tuesday. No precipitation is anticipated though due to the suppression from the upper ridge.
MRMS-(Multi-Radar/Multi Sensor) rainfall estimates across the Lower to Middle Keys were 1 to 2 inches with some localized spots of 2. Due to this, temperatures along the Island Chain are in the mid to upper 70s with dew points in the lower to mid 70s. This is in conjunction with a weak upper level trough continuing to migrate to the southwest slowly. From synopsis, high pressure over the western North Atlantic will maintain gentle to moderate easterly breezes across the Florida Keys.
Rain-free conditions will persist tonight and through Tuesday as 500 mb high pressure, centered over the Gulf Coast states, strengthens.
457 AM CDT Mon Jul 1 2024 - Heat returns over western zones today and along and southeast of a modified cold front working into the area on Tuesday. - Several storm and rain chances set up across the area this morning and increasing into Tuesday afternoon along the modified cold front.
(Today through Tuesday) Monday will be warm and unsettled as a mid-level trough lingers over the region. At the surface, South Florida remains on the periphery of Atlantic high pressure with the ridge axis sitting around Lake Okeechobee. Mid-level high pressure begins to slide east from the southern plains towards the southeastern United States on Tuesday. The high will not build all the way into southern Florida, therefore allowing the unsettled, diurnally-driven storm pattern to continue for another day with a southeasterly wind flow.
847 AM MDT Mon Jul 1 2024 Expect unsettled weather to continue through midweek this week as broad upper level troughing remains in place, bringing daily chances for afternoon showers and thunderstorms across the area. A significant warm up is possible later this week as upper level ridging builds across the Western United States. Broad troughing in place across the Northern Rockies will result in late morning through early evening scattered showers and thunderstorms today.
1028 AM EDT Mon Jul 1 2024 High pressure and a cooler, drier airmass will remain in place across the region today. Ridging will still extend back into the middle Ohio Valley. Meanwhile, mid level ridging will build into the Great Lakes and Ohio Valley. Some high clouds will filter through the mid level ridge, allowing skies to vary between mostly clear and partly cloudy. Meanwhile, the mid level ridge will extend from the lower Ohio Valley northeast into the central/eastern Great Lakes.
906 AM EDT Mon Jul 1 2024 Cooler and drier air works into the region today behind a departing cold front.
