Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Today through Wednesday afternoon) The forecast for the next couple of days will be rather jejune, as an upper ridge will dominate. WV imagery shows said ridge centered over southeast Texas this morning, covering most of the southern CONUS.
A broad, upper level trough is shown by models to remain over the eastern U. , with our region on the southern periphery of the trough through Wednesday.
(Today through Wednesday) Upper high centered near Houston early this morning, with troughing along both the Atlantic and Pacific coasts. At the surface, high pressure centered off the Louisiana coast. Upper ridging will remain near the area through Wednesday, with most modeling reorienting it near Shreveport tomorrow. With ridging close to the area, if there is going to be a preferred area for isolated to scattered convection, it would probably be the Mississippi coast and the lower portions of the Louisiana coastal parishes, where lake/sea breeze boundaries may provide some localized lift.
107 AM EDT Tue Jul 30 2024 High pressure ridge will remain centered offshore through the week gradually building eastwards as the week continues. Warmer tonight, as cloud cover and southerly flow keep lows in the 70s.
Upper level ridging will quickly build in behind the passing upper level disturbance shifting eastward Wednesday.
Red Flag Warnings are in effect for Tuesday afternoon across the majority of southeast Wyoming, mainly along & west of I-25 as we remain in a very hot & dry weather pattern beneath an impressive upper-level ridge encompassing much of the western CONUS.
616 AM CDT Tue Jul 30 2024 (Today through Wednesday) Upper high centered near Houston early this morning, with troughing along both the Atlantic and Pacific coasts. At the surface, high pressure centered off the Louisiana coast. Upper ridging will remain near the area through Wednesday, with most modeling reorienting it near Shreveport tomorrow. With ridging close to the area, if there is going to be a preferred area for isolated to scattered convection, it would probably be the Mississippi coast and the lower portions of the Louisiana coastal parishes, where lake/sea breeze boundaries may provide some localized lift.
(Today and tonight) High pressure will continue to remain in place across the region.
Aloft, an expansive ridge will settle into the region.
Isolated to scattered storms will form mainly across the higher terrain later in the work week.
941 AM CDT Tue Jul 30 2024 Isolated showers continue to stream inland out of the Gulf of Mexico this morning, but this is expected to be the upper limit of precip today as ridging overhead will keep a lid on afternoon convection.
/Issued 318 AM CDT Tue Jul 30 2024/ /Wednesday Onward/ Hot and breezy weather will greet us once again on Wednesday thanks to a strengthening ridge aloft and a tight pressure gradient at the surface. Temperatures will be on the increase through the end of the work week as high pressure remains strong overhead.
(Now through Wednesday) An upper level trough over the eastern seaboard will slowly move east as an upper level ridge builds over the ARK-LA-TEX region. Drier conditions expected across western areas under the influence of the upper ridge.
A 592-594 dm ridge will prevail across the state today and tomorrow. The highest dewpoints are expected to be located across the central and eastern zones of the FA today. The main story is that the ridge will continue across the greater region. The mid level ridge will slowly retrograde enough to out west by the end of the business week. This supports the notion of slightly "cooler" highs. Very little change in the overall weather pattern is expected to finish out the weekend into the next business week with a ridge to our west. A sfc trof will continue today with S winds 10-20 kt across the terminals.
Dewpoints are expected to climb into the low to mid 70s, leaving heat index values of 105 to 113 this afternoon.
(Today through Wednesday) An upper-level ridge will remain over the central plains through the period, supporting broad subsidence and dry conditions.
600 AM CDT Tue Jul 30 2024 (Today and tonight) High pressure will continue to remain in place across the region.
Strong high pressure will build into the area Wednesday.
The highest chances for severe weather will exist in this region, which is highlighted by the SWODY2 and includes southwestern Minnesota.
Below normal temperatures are expected through today with the trough aloft, though interior temperatures are expected to be again 2 to 5 degrees warmer than yesterday's reading. The upper level trough will continue to break down and eject eastward away from the west coast today. As that occurs, upper- level ridging will gradually rise across the region, and a warm deep-layer air-mass will develop across the WRN CONUS.
603 AM CDT Tue Jul 30 2024 (Today through Wednesday afternoon) The forecast for the next couple of days will be rather jejune, as an upper ridge will dominate. WV imagery shows said ridge centered over southeast Texas this morning, covering most of the southern CONUS.
1031 AM EDT Tue Jul 30 2024 A frontal boundary and low pressure system will move through the area later today into Wednesday with some showers and thunderstorms.
Today through Wednesday Night: The trough is beginning to exit the region. Winds will be lighter Wednesday as high pressure begins to build across the region.
- A cold front starts to work southeast on Wednesday, but southeastern zones continue to look very hot with another day of over 105 heat index values mainly southeast of the Tri- Cities.
Looking more broadly at the other features that are driving our weather today we see high pressure in the Gulf, another more expansive high in the North Atlantic, and a TUTT cell centered near Jamaica. Winds have veered to the east to southeast as the high in the North Atlantic builds gradually across the region. From synopsis, high pressure will maintain light to gentle east to southeast winds across the region through the afternoon. Breezes will freshen beginning tonight through the latter part of this week as high the high continues to build. This high will work in tandem with a disturbance currently west of the Lesser Antilles to tighten the pressure gradient, increasing breezes further by the start of the weekend.
How far east any of the activity travels is a question, but forcing is best around the trough even though shear is weak to moderate at 25 to 30 kts. Another round of severe storms is possible on Wednesday as a trough moves east through the state.
620 AM CDT Tue Jul 30 2024 (Today through Wednesday) Mid and upper level ridging will build into the area from the northeast through the short-term. With the exception of a stray shower or two today across Lavaca and DeWitt counties, the region will remain dry and warmer today and Wednesday.
641 AM EDT Tue Jul 30 2024 - Confidence continues on the lower side regarding the potential of impacts from 1 or more thunderstorm complexes, mainly tonight through Wednesday night.
542 AM CDT Tue Jul 30 2024 (Today) Dome of high pressure has become the dominate feature across the Southern Plains and will remain that way today. the low level thermal ridge is expected to expand eastward slightly which should allow for afternoon temperatures to be at or a degree or so warmer today compared to yesterday.
Additionally, the H5 ridge will build back SWrd toward the area resulting in mid-lvl height rises and modest synoptic subsidence.
An elongated ridge centered over Texas and low pressure system sitting across the Pacific Northwest have created a mostly dry, westerly flow across northern Arizona. The exception to this is the area of high pressure to our east allowing enough moisture to funnel in from the south to create isolated showers and thunderstorms across southern Apache County and Navajo County this afternoon/evening. By Wednesday, the previously mentioned ridge will begin to push westward and eventually settle across much of the western CONUS.
641 AM CDT Tue Jul 30 2024 (Today through Wednesday) An upper-level ridge will remain over the central plains through the period, supporting broad subsidence and dry conditions.
Did go above NBM on dew pts today and on the higher side of HRRR as well with more widespread low 70 dew pts within RRV and E ND vs upper 60s.
631 AM EDT Tue Jul 30 2024 A frontal boundary and low pressure system will move through the area later today into Wednesday with some showers and thunderstorms.
940 AM EDT Tue Jul 30 2024 The Atlantic ridge axis will remain across the region today, with a light S/SE flow in the lower levels. It will be a hot and humid day, with highs in the low 90s at the coast and low to mid 90s over the interior, with peak heat index values around 101-106F.
1254 PM MDT Tue Jul 30 2024 - Hot today, but cooler on Wednesday behind a cold front, then hot again the rest of the week into the weekend.
However, this benign pattern begins to change as we head into Wednesday with a gradual return of monsoonal moisture from the south as high pressure builds and strengthens once again over much of the West. An elongated ridge centered over Texas and low pressure system sitting across the Pacific Northwest have created a mostly dry, westerly flow across northern Arizona. The exception to this is the area of high pressure to our east allowing enough moisture to funnel in from the south to create isolated showers and thunderstorms across southern Apache County and Navajo County this afternoon/evening. By Wednesday, the previously mentioned ridge will begin to push westward and eventually settle across much of the western CONUS.
204 PM EDT Tue Jul 30 2024 A frontal boundary and low pressure system will move through the area this evening into Wednesday with numerous showers and thunderstorms expected.
324 PM CDT Tue Jul 30 2024 - Heat impacts continue through sunset, with many spots seeing heat index values in the low to mid 90s. Southwesterly flow ahead of the main trough over the northern Rockies will continue tonight into tomorrow, with a transition to more northwesterly flow as the trough digs into the midwest later in the week.
(Rest of today through Wednesday) South Florida remains under a weakness in Atlantic high pressure. Drier air arrives by Wednesday with a Saharan air layer intrusion which will not only contribute to lower convective coverage in the afternoon but lead to a warm up in temperatures into the lower to mid 90s.
Across the High Plains, a hot/well-mixed boundary layer and weak dryline circulation are beginning to foster widely scattered convective development. Dangerous heat is expected to continue on Wednesday, as an upper ridge axis remains centered across the Central Plains.
/NEW/ /Through Wednesday/ Hot and quiet weather will prevail through mid-week beneath a dominant upper level ridge. /Issued 318 AM CDT Tue Jul 30 2024/ /Wednesday Onward/ Hot and breezy weather will greet us once again on Wednesday thanks to a strengthening ridge aloft and a tight pressure gradient at the surface. Temperatures will be on the increase through the end of the work week as high pressure remains strong overhead.
There may be opportunities for some light passing showers today and Wednesday, however, a mid to upper level ridge remains overhead and will limit rain chances. For tonight, expect partly cloudy skies and lows in the mid to upper 70s inland and in the low 80s along the coast. Similar to today, the highs on Wednesday will be generally in the low to mid 90s.
Upper ridging remains a prominent feature across much of the US through the work week as an upper 5H low swings over the OH Valley before becoming enveloped within the large scale trough this weekend. NCEP's Integrated Water Vapor Transport shows abundant moisture advecting from the Gulf around the upper ridge and directly into the our region, resulting in high PWAT values ranging from 1.
A weak boundary/trough axis was the focus of a few showers to the east.
1211 PM CDT Tue Jul 30 2024 (Rest of Today) Late this morning the area is situated along the eastern flank of a broadening upr ridge and the western flank of an East Coast upr trough. Temperatures should rise into the low/mid 90s today at most locations, and combined with dew points in the mid/upr 70s, will produce heat indices in the 105 to 110 F range for most of the area.
121 PM EDT Tue Jul 30 2024 - Confidence continues on the lower side regarding the potential of impacts from 1 or more thunderstorm complexes, mainly tonight through Wednesday night.
The Atlantic ridge axis will remain across the region today, with a light S/SE flow in the lower levels. It will be a hot and humid day, with highs in the low 90s at the coast and low to mid 90s over the interior, with peak heat index values around 101-106F.
300 PM EDT Tue Jul 30 2024 High pressure ridge will remain centered offshore through the week gradually building eastwards as the week continues.
1247 PM CDT Tue Jul 30 2024 Isolated showers continue to stream inland out of the Gulf of Mexico this morning, but this is expected to be the upper limit of precip today as ridging overhead will keep a lid on afternoon convection.
With high PW values, high temperatures will be in the low to mid 90s today.
(This afternoon through Wednesday night) Upper level ridge remains over the ArkLaTex for the short term and will amplify over the next day or two. The strengthening ridge in combination with southeast flow will keep lows tonight just above average in the mid 80s for most. Most notably the Pecos River Valley and across the Permian Basin will reach into the low 100s. Rain chances are existent particularly across the western higher terrain where the influence of the ridge is noticeably weaker.
Mesoscale convection has blossomed in the nearshore waters of the Lower Keys. Mostly sunny skies have allowed temperatures to reach the lower 90s, making for another seasonably toasty late July afternoon.
A low-pressure system moving through north-central Idaho and western Montana has brought widespread rainfall to the region. This low-pressure system is expected to move eastward out of the region by this evening, with most storms anticipated to dissipate by late evening. Model guidance shows strong consensus that high pressure will start building back into the Northern Rockies beginning on Wednesday.
This is due to prolonged ridging across the Southern Great Plains that will linger across the area, only deviating in shape and slowly weakening in intensity over the next 36 hours. This synoptic setup will maintain fairly light winds and dew points in the low-to-mid 70s.
(Tomorrow through Tuesday) High pressure remains centered over the southern plains for the next several days with dangerous heat expected to continue through the entire period.
- Slightly cooler temperatures late in the week into the weekend, though still above normal for this time of the year. While a weak cold front will sag southward over the area, much of the region will still warm to slightly above seasonal values, with the plains rising into the upper 90s to low 100s, the valleys warming into the mid 80s, and the mountains reaching into the upper 50s to low 60s.
/Issued 1230 PM CDT Tue Jul 30 2024/ /Through Wednesday/ Hot and quiet weather will prevail through mid-week beneath a dominant upper level ridge.
A 592-594 dm ridge will prevail across the state today and tomorrow. The highest dewpoints are expected to be located across the central and eastern zones of the FA today. The main story is that the ridge will continue across the greater region. The mid level ridge will slowly retrograde enough to out west by the end of the business week. This supports the notion of slightly "cooler" highs. Very little change in the overall weather pattern is expected to finish out the weekend into the next business week with a ridge to our west.
338 PM EDT Tue Jul 30 2024 - Low chance of storms through Wednesday night - Showers/storms Thu/Fri, hot and humid, then drier and a bit cooler - Low chance of storms through Wednesday night To start, we have a few isolated showers re-firing near/east of U. - Showers/storms Thu/Fri, hot and humid, then drier and a bit cooler Not much change to the going forecast.
Upper level trough exiting the area this morning with an upper level ridge beginning to build this afternoon.
The low stratus deck is expected to briefly clear late this afternoon or early this evening, then redevelop overnight with some patchy dense fog in places that received rainfall today.
DS/12 (00Z TAFS) (Now through Wednesday) An upper level trough over the eastern seaboard will slowly move east as an upper level ridge builds over the ARK-LA-TEX region. Drier conditions expected across western areas under the influence of the upper ridge.
1230 PM CDT Tue Jul 30 2024 (Today through Wednesday) An upper-level ridge will remain over the central plains through the period, supporting broad subsidence and dry conditions.
158 PM MDT Tue Jul 30 2024 A short wave trough and a cold front will move through this afternoon and evening, bringing an increased chance (40-60%) of showers and thunderstorms moving west to east. As the cold front passes through, smoke is expected to decrease across the region. Then, ridging will build in for Wednesday, leading to drier, calmer conditions.
1231 PM CDT Tue Jul 30 2024 (Today and tonight) High pressure will continue to remain in place across the region.
1207 PM CDT Tue Jul 30 2024 (Today through Wednesday afternoon) The forecast for the next couple of days will be rather jejune, as an upper ridge will dominate. WV imagery shows said ridge centered over southeast Texas this morning, covering most of the southern CONUS.
(Tonight through Wednesday night) 500mb ridging will remain in firm control over the short term period, with temperatures warming to near seasonal normals for the first time in over a week for South Central Texas.
In addition, localized enhancement of the low level shear mainly near the boundary may be significant enough for a brief tornado.
Afternoon temperatures will trend warmer, including above average highs by Wednesday.
Ridging will begin to build over the region tomorrow, opening the door for the return of monsoonal moisture during the second half of the week.
The combination of unstable atmosphere and the higher precipitable water aid in the formation of the thunderstorms. The higher chances for thunderstorms will be along the international border. The high pressure center will give the southerly flow aloft and along with a subtle feature coming across to help initiate thunderstorm activity. For the rest of the week, high pressure will move around the region towards the Four Corners and then eventually to the Great Basin.
(Tonight through Wednesday night) Deep South Texas will remain under the influence of ridging aloft through the short term period, which will result in near normal temperatures for late July and mostly rain-free conditions. An enhanced pressure gradient along the Lower Texas Coast will result in breezy southeasterly winds tonight into tomorrow, with wind around 15-20 MPH and gusts up to 25 MPH.
253 PM EDT Tue Jul 30 2024 The setup aloft this afternoon over the region features troughing extending south from a closed low over New England with ridging to the west and east of the state. At the surface, the Atlantic ridge extends over southern Florida, keeping a light easterly wind in place.
(Rest of Today) Late this morning the area is situated along the eastern flank of a broadening upr ridge and the western flank of an East Coast upr trough. Temperatures should rise into the low/mid 90s today at most locations, and combined with dew points in the mid/upr 70s, will produce heat indices in the 105 to 110 F range for most of the area.
(This evening through Wednesday) An upper-level ridge is evident over Texas on water vapor imagery this afternoon, along with a low near Maine and a trough in the northern Rockies. The ridge will remain the dominant synoptic feature over the CWA through the short term period.
Showers this morning are accompanying an upper trough tracking through central Idaho. Even the lower Snake Plain (Ontario to Boise) has seen measurable precipitation (0.
Cloudy skies and light showers will persist throughout the day as an upper trough exits to the east. A high pressure ridge will build over the western US through the rest of the week and into the weekend, allowing for above normal temperatures and dry conditions to return.
/NEW/ /Tonight through Wednesday Night/ Ridging will dominate the weather pattern over the next 36 hours with the mid level high center over the Arklatex through Wednesday keeping things hot and dry across North and Central TX.
Currently - A complicated mid latitude trough parked over the eastern United States continues to keep the western flank of the lower tropospheric Atlantic ridge weakened and partially split near the Florida Peninsula. This activity mainly affected the Lower Keys in the late afternoon hours. More recently, boundary layer stabilization, along with drier air moving in through the lower levels has considerably diminished the shower activity across the forecast area. Short Term Update - The lower tropospheric ridge will rebuild a bit across our longitude and will push east to southeasterly breezes up slightly. The lower levels are expected to dry further and some low level inhibition should build in. As a result, expect overnight lows to be in the lower to mid 80s and dew points remaining in the mid 70s. Atlantic ridging will firm up across the Florida Peninsula overnight.
Expect morning lows to cool down to the mid to upper 70s inland, and in the low 80s near the coasts. (Rest of today through Wednesday) South Florida remains under a weakness in Atlantic high pressure. Drier air arrives by Wednesday with a Saharan air layer intrusion which will not only contribute to lower convective coverage in the afternoon but lead to a warm up in temperatures into the lower to mid 90s.
700 mb temperatures will be about 4 to 6 degrees cooler than today, leading to high temperatures that are about 5 to 10 degrees cooler.
High pressure then builds in for the second half of the work week and brings a return to dry and hot conditions. A passing trough will continue to bring variable clouds, showers, and a few isolated thunderstorms through this evening. Ridging aloft builds in for the second half of the work week for a return to hot and dry conditions.
326 PM MDT Tue Jul 30 2024 - Hot and dry weather continues, with critical fire weather conditions across the higher terrain today.
Strong high pressure will build into the area Wednesday through late in the week brining a warming trend.
634 PM CDT Tue Jul 30 2024 - Heat impacts continue through sunset, with many spots seeing heat index values in the low to mid 90s. Southwesterly flow ahead of the main trough over the northern Rockies will continue tonight into tomorrow, with a transition to more northwesterly flow as the trough digs into the midwest later in the week.
- Warm and dry conditions continue Wednesday with lighter winds and slightly warmer temperatures.
510 PM MDT Tue Jul 30 2024 - Hot today, but cooler on Wednesday behind a cold front, then hot again the rest of the week into the weekend.
The main weather headline for tomorrow will continue to be the excessive heat, as the ridge continues to build across the Mid- South.
536 PM CDT Tue Jul 30 2024 (This afternoon through Wednesday night) Upper level ridge remains over the ArkLaTex for the short term and will amplify over the next day or two. The strengthening ridge in combination with southeast flow will keep lows tonight just above average in the mid 80s for most. Most notably the Pecos River Valley and across the Permian Basin will reach into the low 100s. Rain chances are existent particularly across the western higher terrain where the influence of the ridge is noticeably weaker.
647 PM CDT Tue Jul 30 2024 (Tonight through Wednesday night) 500mb ridging will remain in firm control over the short term period, with temperatures warming to near seasonal normals for the first time in over a week for South Central Texas.
419 PM MDT Tue Jul 30 2024 - Hot and dry weather continues, with critical fire weather conditions across the higher terrain today.
