Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Tonight) Warmer temperatures are on tap for tonight across eastern Oklahoma and western Arkansas as low level moisture increases across the region on the heels of a weak southerly low level flow.
300 PM EDT Mon Jul 10 2023 Dry weather is expected through Tuesday under high pressure. Building high pressure across the Ohio Valley region will maintain dry weather tonight. Dry weather should continue Tuesday as high pressure moves east across the Ohio Valley region.
The exception to this will be along the coast and in the Lower Rio Grande Valley, where the high temperatures are expected to be in the upper 90s. As the expected subsidence from the high should bring some drier air towards the surface. While the low temperatures are expected to be in the upper 70s to low 80s, the sensible temperature will feel much warmer than that overnight closer to the mid 80s to 90s.
255 PM EDT Mon Jul 10 2023 High pressure builds in from the west into mid week. Highs in the u80s-around 90F Tue w/ l-m90s for Wed (slightly cooler both days at the beaches). Rain chances (for mainly diurnal SHRAs/tstms) increase late Thu-Mon as a broad trough aloft settles towards the ern CONUS and a sfc cold front slowly settles near the local area. A weak cold front moved off the coast earlier this morning and is resulting in NW winds at 5-10 kt this afternoon.
In the small hours of tomorrow morning, the stalled surface boundary which has been responsible for our recent rounds of convection will begin to lift to the north as a pseudo warm front, returning storm chances to north central Louisiana after 09Z, spreading north by daybreak.
133 PM MDT Mon Jul 10 2023 For the first half of the week a ridge will keep WY hot and dry. By the end of the week into this weekend the ridge will flatten, which should drop temperatures back to near normal and bring in slight chances for thunderstorms.
322 PM EDT Mon Jul 10 2023 High pressure will build across the region tonight. Dry and seasonably mild conditions are expected through Tuesday before warmer and more humid air builds back into the Ohio Valley by midweek and beyond. With high pressure dominating and light winds, some fog will develop later tonight, mainly in river valleys. Temperatures will bottom from the upper 50s to the lower 60s. Milder temperatures with Tuesday night lows from the lower 60s to the upper 60s.
Dew points will be more comfortable in the low to mid 60s. Humidity, warmer temperatures, and unsettled weather return by the end of the week. Aside from the fog, it's muggy (obviously) and thanks to that cold front, it's also cooler with most observation sites sitting around the 60s. The start of the new work week is looking fantastic with mostly sunny skies and highs in the upper 80s/low 90s with cooler overnight lows in the mid 60s.
Cold frontal passage working south across the CWA is now south of U. Just a question of whether or not the mid/upper atmosphere will produce some form of lift to aide the low frontal-forcing and help convection to get going. A southward-moving cold front can now be seen on radar, and is about to cross from southeastern ND into northeastern SD. Moving forward, the passage of this cold front will be the main driver for our weather today, as it will be associated with a wind shift to north/northeasterly winds, moderate low-level CAA with cooler temps, and a slight chance for showers and storms across the southeastern CWA.
Temperatures and humidity will increase through midweek, as an upper level ridge of high pressure over New Mexico expands to the east.
A cold front continues to drop south this afternoon. This boundary should continue to drop south in conjunction with the cold front. Overnight, mostly clear skies and cooler air behind the cold front will likely lead to a chilly summer night, with overnight lows in the 40s, possibly into the high 30s in locally cold spots over north- central and northeast Minnesota. Cooler, drier air arrives Tuesday with some high pressure building in.
101 PM EDT Mon Jul 10 2023 High pressure builds in from the west into midweek. Weak cold front off the coast.
Winds across the area are generally light out of the southwest with temperatures in the low to middle 60s. This afternoon, the upper level ridge centered near the Continental Divide has the area under a northwesterly flow aloft. Afternoon highs are forecast to be in the low to middle 90s with overnight lows in the 60s. On Tuesday, the upper ridge becomes deamplified and flow aloft backs to become more zonal.
1244 PM CDT Mon Jul 10 2023 A July cold front has ushered in a welcomed drier airmass across the Midsouth.
217 PM CDT Mon Jul 10 2023 High pressure will gradually settle south of the Ohio River Valley tonight into Tuesday but will continue to provide fair weather across central Illinois in the near term. Temperatures will fall into the lower to mid 60s overnight under mostly clear skies.
(Through Tuesday) A weak cold front has slid into our forecast area and is expected to stall over the northern half of the area through Tuesday. Lows will be in the low to mid 70s.
340 PM CDT Mon Jul 10 2023 (Issued 340 PM CDT Mon Jul 10 2023) Tonight and Tuesday: A cold front will drop through southern Wisconsin tonight. It won't be as warm tomorrow behind the front, with northeast winds keeping it even cooler near lake Michigan.
The synoptic pattern through mid week will feature rising upper level heights as a trough currently over the northeast U.
Temperatures will warm considerably later in the week as upper level ridging becomes the dominant feature.
107 PM MDT Mon Jul 10 2023 Most recent Water Vapor and upper air analysis shows upper ridge sitting over the rockies/northern plains, and closed upper low over northern Ontario, with troughing in the New England region. Today will be the warmest day of the week, as the ridge slides over the region. Might see a warmer, dry weekend as the upper low shifts eastward and upper ridging builds over the western CONUS, however much will depend on the track of the upper low as it shifts. If upper ridge builds strongly over the western US in the long range as some models are showing, we may finally see a prolonged period of warm and dry weather nearing the end of the month.
209 PM EDT Mon Jul 10 2023 An upper level trough with its cool air aloft will drift east across the region today. High pressure at the surface and aloft will return for Tuesday, accompanied by mostly sunny skies, slightly below normal high temperatures and comfortable humidity.
1003 AM CDT Mon Jul 10 2023 Cold frontal passage working south across the CWA is now south of U. Just a question of whether or not the mid/upper atmosphere will produce some form of lift to aide the low frontal-forcing and help convection to get going. A southward-moving cold front can now be seen on radar, and is about to cross from southeastern ND into northeastern SD. Moving forward, the passage of this cold front will be the main driver for our weather today, as it will be associated with a wind shift to north/northeasterly winds, moderate low-level CAA with cooler temps, and a slight chance for showers and storms across the southeastern CWA.
Strong onshore flow today, with clouds and cooler temperatures.
1208 PM CDT Mon Jul 10 2023 (Today through Tuesday) Current synoptic pattern analysis shows a ridge over the 4-Corners region, Bermuda ridge in the western Atlantic, and a mid latitude trough draped south from Canada to the Gulf Coast just east of the Mississippi River. This setup puts the CWA within northwest flow on the eastern edge of the ridge to the west.
114 PM EDT Mon Jul 10 2023 A weak cold front will stall over the area today and meander nearby into mid week before dissipating. An inland trough will develop later in the week as high pressure begins to build over the Atlantic. At the surface, a cold front currently positioned near the far interior counties, will sink south and stall out over the area later today. Otherwise, high temperatures will limited a bit by extensive cloud cover and convection; peaking in the lower- mid 80s.
1121 AM EDT Mon Jul 10 2023 Low pressure over the area today will move slowly northeast into New England through tonight.
1256 PM EDT Mon Jul 10 2023 High pressure builds in from the west into midweek. Weak cold front off the coast.
(Tonight) Cold front has now sagged further southward into the central Gulf Coast this Mon afternoon. Early afternoon temps are also running a few degrees below normal, with current readings predom in the lower 80s/near 80F. Otherwise, high pressure over the Mid South region will continue to nudge eastward tonight, maintaining dry wx conditions into early Tue. Overnight lows look to fall into the lower/mid 60s for most spots, which is also a few degrees below seasonal values.
Rain chances gradually increase southward, but similar to today, there should be enough dry air across southwest Florida to keep the highest probabilities along the I-4 corridor northward. Frontal boundary along north Florida with high pressure over the Gulf will keep west to southwest flow in place for the next few days, with winds generally expected to remain below headlines, though speeds around 15 knots can be expected at times.
606 PM CDT Mon Jul 10 2023 (Tonight) Cold front has now sagged further southward into the central Gulf Coast this Mon afternoon. Early afternoon temps are also running a few degrees below normal, with current readings predom in the lower 80s/near 80F. Otherwise, high pressure over the Mid South region will continue to nudge eastward tonight, maintaining dry wx conditions into early Tue. Overnight lows look to fall into the lower/mid 60s for most spots, which is also a few degrees below seasonal values.
700 PM EDT Mon Jul 10 2023 A cold front will slowly push off the coast tonight. Following the front, a typical summertime pattern with high pressure offshore and troughing inland will redevelop through late this week bringing hot and muggy weather.
619 PM EDT Mon Jul 10 2023 Dry weather is expected through Tuesday under high pressure. Clear skies are expected through the early overnight period with notable drying through the entire atmospheric column with decent and building high pressure. Dry weather should continue Tuesday as high pressure moves east across the Ohio Valley region.
-Enriquez Previous Discussion: Backdoor cold front moved through this morning and is bringing some weak cold air advection into the area. Tonight showers and thunderstorms will move into the are as an upper level Low moves in from the Pacific Northwest. Shower and thunderstorm chances remain across the area tomorrow as that upper level Low passes by.
635 PM CDT Mon Jul 10 2023 Temperatures and humidity will increase through midweek, as an upper level ridge of high pressure over New Mexico expands to the east.
724 PM CDT Mon Jul 10 2023 (This evening through Tuesday) A broad upper level trough in the eastern CONUS will continue through the short term. In central Alabama, surface winds have also largely come around to the north as a cold front starts to push through the area.
(Tonight) Tranquil weather across the Tennessee Valley this evening with high pressure promoting clear and dry conditions. Light northerly flow at the surface has helped to reinforce this drier air mass as seen by dewpoints in the lower 60s as of 02z. This will allow low temperatures to run about 5 degrees cooler than last night -- with most locations dropping into the low to mid 60s. These cooler temperatures will make it feel quite comfortable for early/mid July.
After a few showers and thunderstorms this evening, slightly cooler air will arrive across North Central and Southwestern Montana, keeping highs in the 70s and 80s the next few days. In addition to the cooler temperatures, tranquil weather is also expected, with only a few isolated thunderstorms after midweek. Earlier forecasts, and still this one to a degree, were keying in on the potential for strong to possibly severe thunderstorms across the area, but some early morning cloud cover across Central and Southwestern Montana helped to keep temperatures a bit cooler than expected across parts of the area, which in turn kept the atmosphere a bit more stable. Beyond tonight, our weather will turn a bit cooler and more tranquil as the upper level flow becomes more zonal (westerly).
The setup aloft this afternoon features troughing over much of the eastern part of the country with ridging south of Florida. The base of the trough extends over about the northern half of the Florida peninsula with the northern extent of the ridge over the southern part of the peninsula. At the surface, the Atlantic ridge axis extends westward over the Florida straits while a frontal boundary remains draped across the southeastern U. With the boundary lingering over north Florida, the highest rain chances will continue over the northern part of the forecast area through Tuesday, with hot and humid conditions elsewhere. Rain chances remain on the high side for our northern waters for the rest of today as a frontal boundary slowly sinks southward.
557 PM EDT Mon Jul 10 2023 Low pressure over New England tracks slowly northeast tonight. Weak high pressure builds to the south and west late tonight into Tuesday, and into the area Tuesday night.
532 PM MDT Mon Jul 10 2023 Our wave is crashing into the crest of the ridge as we speak and losing steam quickly. This wave and a stronger wave moving along the northwest border of the CONUS will be damping the northern amplification of ridge which will push the jet stream to slightly lower latitudes.
A short wave upper level ridge is moving in overhead this afternoon.
Some patchy fog will start to develop a little after midnight along the Highway 82 corridor. Low temperatures tonight will continue to hang around the low 70s along and south of the Interstate 20 corridor and upper 60s north of I-20. A cold front stalled over the corridor keeping dry air and dewpoints relatively low in the low 70s going into the upper 60s. Low temperatures overnight will range from the upper 60s above I-20 and the low 70s below. For Tuesday, a stalled cold front will lift further north as the boundary will be just shy of reaching I-20.
1034 PM EDT Mon Jul 10 2023 Low pressure over New England tracks slowly northeast tonight. Weak high pressure builds to the south and west late tonight into Tuesday, and into the area Tuesday night.
The prevailing weather conditions in our region are currently characterized by a weak ridge and a dry Saharan air mass , observed at 700 to 600 MB. In other locations, the temperatures varied between the lower and middle 90s. In line with the preceding evening, the high-resolution guidance does not exhibit any indication of the formation of precipitation over the nearby bodies of water and land areas.
304 PM PDT Mon Jul 10 2023 A cold front is bringing thunderstorms with locally heavy rain and frequent lightning to portions of the Inland Northwest this afternoon, though coverage is expected to decrease tonight.
High pressure will be strengthening over Nevada this week, with hotter summer temperatures later in the week. Trailing portion of Pacific Northwest trough drags a thin ribbon of moisture (scattered low topped convective clouds) across northern Elko County. Temperatures will be above normal, and will be trending higher with subtropical ridge expanding westward on Tuesday.
941 PM CDT Mon Jul 10 2023 (Issued 941 PM CDT Mon Jul 10 2023) Thunderstorms continue to slowly shift southeastward from the Upper Peninsula of Michigan to northeast Wisconsin back into southeast Minnesota, along and ahead of a cold front. Wood (Issued 340 PM CDT Mon Jul 10 2023) Tonight and Tuesday: A cold front will drop through southern Wisconsin tonight. It won't be as warm tomorrow behind the front, with northeast winds keeping it even cooler near lake Michigan.
451 PM MDT Mon Jul 10 2023 Most recent Water Vapor and upper air analysis shows upper ridge sitting over the rockies/northern plains, and closed upper low over northern Ontario, with troughing in the New England region. Today will be the warmest day of the week, as the ridge slides over the region. Might see a warmer, dry weekend as the upper low shifts eastward and upper ridging builds over the western CONUS, however much will depend on the track of the upper low as it shifts. If upper ridge builds strongly over the western US in the long range as some models are showing, we may finally see a prolonged period of warm and dry weather nearing the end of the month.
Due to the near ground moisture and slightly cooler overnight lows in the 60s, patchy fog will be possible. 75 Previous short-term discussion: (This evening through Tuesday) A broad upper level trough in the eastern CONUS will continue through the short term. In central Alabama, surface winds have also largely come around to the north as a cold front starts to push through the area.
Much warmer conditions are then expected during mid to late week. Northwest California remains on the northwestern periphery of an upper level ridge.
As high pressure builds north and west, warmer and drier conditions are expected later in the week.
731 PM EDT Mon Jul 10 2023 High pressure will build across the region tonight. With high pressure dominating and light winds, some fog will develop later tonight, mainly in river valleys. Temperatures will bottom from the upper 50s to the lower 60s. Milder temperatures with Tuesday night lows from the lower 60s to the upper 60s.
These temperatures are trending approximately 5 to 10 degrees warmer than this time yesterday afternoon across our County Warning Area (CWA) as of 2 PM PDT. Ensemble guidance indicates the upper level trough will continue to move across the Pacific Northwest today, as an upper level ridge develops over the Desert Southwest. This ridge will continue to build this week, allowing for gradual day to day warming and dry weather conditions to prevail.
801 PM EDT Mon Jul 10 2023 A weak cold front will stall over the area tonight and meander nearby into mid week before dissipating. An inland trough will develop later in the week as high pressure begins to build over the Atlantic. cooler than we've seen in a bit of time. Mid and upper level ridging will stretch from the southwest United States into the Gulf of Mexico and then into the ocean east of the Bahamas through the period, while a deep cyclone persists over or near Hudson Bay in Canada.
1021 PM EDT Mon Jul 10 2023 High pressure will build across the region tonight. Temperatures will range from the upper 50s to the lower 60s. Milder temperatures with Tuesday night lows from the lower 60s to the upper 60s.
1000 PM EDT Mon Jul 10 2023 A cold front will slowly push off the coast tonight. Following the front, a typical summertime pattern with high pressure offshore and troughing inland will redevelop through late this week bringing hot and muggy weather.
A weak short wave trough moving eastward along the Canadian border brought slight cooling to our CWA, and tonight's lows will also be cooler than last night.
919 PM EDT Mon Jul 10 2023 High pressure will build over the area on Tuesday bringing mostly sunny and pleasantly warm conditions with more comfortable humidity levels.
705 PM EDT Mon Jul 10 2023 Low pressure over New England tracks slowly northeast tonight. Weak high pressure builds to the south and west late tonight into Tuesday, and into the area Tuesday night.
826 PM EDT Mon Jul 10 2023 High pressure builds in from the west into mid week. Hodographs are not supportive at all of mesocyclone circulations at this time and circulations we've had have been weak (VRot < 10-15kt). As weak CAA continues and PWs drop slowly, expect any lingering convection quickly fades in the next hour or so, with a cooler, more comfortable evening ahead. Highs in the u80s-around 90F Tue w/ l-m90s for Wed (slightly cooler both days at the beaches). Rain chances (for mainly diurnal SHRAs/tstms) increase late Thu-Mon as a broad trough aloft settles towards the ern CONUS and a sfc cold front slowly settles near the local area. A weak cold front moved off the coast earlier this morning and is resulting in NW winds at 5-10 kt this afternoon.
535 PM EDT Mon Jul 10 2023 An upper level trough with its cool air aloft will drift east across the region today. High pressure at the surface and aloft will return for Tuesday, accompanied by mostly sunny skies, slightly below normal high temperatures and comfortable humidity.
Behind this cold front, surface temperatures have dropped into the low 60s in central Minnesota.
Winds will be on the higher end of this range for DLS, which is the only site that will not experience decreasing winds of 10kts or less through the overnight period.
753 PM EDT Mon Jul 10 2023 An upper level trough with its cool air aloft will drift east across the region today. High pressure at the surface and aloft will return for Tuesday, accompanied by mostly sunny skies, slightly below normal high temperatures and comfortable humidity.
641 PM CDT Mon Jul 10 2023 (Tonight) Warmer temperatures are on tap for tonight across eastern Oklahoma and western Arkansas as low level moisture increases across the region on the heels of a weak southerly low level flow.
707 PM EDT Mon Jul 10 2023 Dry weather is expected through Tuesday under high pressure. Clear skies are expected through the early overnight period with notable drying through the entire atmospheric column with decent and building high pressure. Dry weather should continue Tuesday as high pressure moves east across the Ohio Valley region.
High pressure centered over the mid-Mississippi Valley this evening will drift east into Kentucky and Tennessee tonight, bringing clear skies and nearly calm winds. Lows tonight will be a couple degrees warmer than last night. We'll have another quiet weather day on Tuesday as the high weakens slightly but doesn't move much. Upper pattern continues to feature a closed upper low and trough over central Canada dipping into the upper Midwest with strong ridging centered over the Desert Southwest and northern Mexico stretching northward into the Four Corners and Intermountain West.
723 PM EDT Mon Jul 10 2023 (Through Tuesday) A weak cold front has slid into our forecast area and is expected to stall over the northern half of the area through Tuesday. Lows will be in the low to mid 70s.
246 AM EDT Tue Jul 11 2023 High pressure builds in from the west into mid week.
133 AM EDT Tue Jul 11 2023 High pressure will build over the area on Tuesday bringing mostly sunny and pleasantly warm conditions with more comfortable humidity levels. A weak cold front will slide into Northern PA Wednesday and stall out there.
A cold front is slowly moving south across Minnesota and Wisconsin through the rest of the day into tonight. Severe winds are also a concern, especially if we see upscale growth into a linear system along the cold front. Behind the front cooler and drier air will settle in with below normal temperatures and dry weather during the day on Tuesday.
A cold frontal system will become quasi-stationary just north of the Florida-Georgia State-line today. A thin band of convection currently moving across the area is a pre-frontal trough which will become the focusing mechanism for convection later this morning and into the late evening, mainly across north Florida south of State Road 16.
A weak warm front will move into the region on Wednesday bringing scattered thunderstorms and warmer temperatures to the region.
An upper level ridge will cause dewpoints to surge to the mid-to upper 70s on Wednesday, bringing heat indices near or in exceedance of heat headlines.
Activity over much of the area was being driven by an upper jet, while the N-S line of storms over Fallon and Carter Counties was associated with an approaching cold front and the low-level jet. Cold front will move E of the area in the afternoon with cooler air surging through the area tonight. Weak ridging will bring a dry night Wed.
435 AM EDT Tue Jul 11 2023 Short Term/Marine Thunderstorms are currently moving across Lake Michigan along an axis of elevated instability, low level convergence, higher surface dew points ahead of the cold front, and along a low level jet pointing at central Lower Michigan.
