Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Today through Saturday afternoon) Much of the area will remain under the influence of high pressure over central Texas today. Clear to partly cloudy skies and southerly winds will send highs into the 90s for all but the higher elevations in the CWA. A deep upper low over the western United States will create enough instability in the western fringes of the area that isolated to widely scattered thunderstorms will be possible from southeastern New Mexico and into the Big Bend which is the only area that could see rainfall today. Things change Saturday as the upper low moves east and closer to New Mexico and West Texas.
1247 AM CDT Fri Sep 20 2024 Gulf Coast region remains on the eastern periphery of ridging over the International Border, locking in dry northwest flow, per 1.
1202 AM CDT Fri Sep 20 2024 (Tonight) High pressure promoting mostly clear and calm conditions overnight across the Tennessee Valley. Once again, this is a good setup for radiational cooling as temperatures fall back into the low to mid 60s in most locations.
348 AM EDT Fri Sep 20 2024 High pressure remains in control through Friday promoting mainly dry and mild conditions.
1237 AM CDT Fri Sep 20 2024 (Tonight through Friday night) An upper level ridge continues to reside over the southern plains this afternoon. The low level pressure field is somewhat ill defined. The upper ridge will shift ever so slowly toward the east during the short term period. Models show the low level flow becoming better established from the southeast tonight, and that will continue through Friday night. Subsident flow from the upper ridge will keep the weather dry through the period.
Dry and warmer tomorrow, with temperatures around 5 to 8 degrees above normal. Tomorrow, expect a dry day with warmer temperatures as the ridge further builds across the area. Based on the higher temps, we can expect min RH values down in the mid to upper 30s for some areas.
/NEW/ /Today and Saturday/ Seasonally anomalous hot/humid conditions will intensify today as the center of a strong upper-level ridge remains focused over the region. By Saturday, the center of the prevailing ridge will begin to shift southward over Central Texas as a southern stream upper low/trough pushes towards the Four Corners region.
(Today through Saturday Night) Upper level ridging will continue, keeping calm and warmer than normal weather over SE Texas.
109 AM EDT Fri Sep 20 2024 High pressure remains in control through Friday promoting mainly dry and mild conditions.
353 AM EDT Fri Sep 20 2024 High pressure remains in control through Friday promoting mainly dry and mild conditions.
(Today through Saturday) An impressive 500 mb ridge will become centered over South Texas today with a ridge axis extending to the northeast. Similar conditions are expected Saturday as the ridge slowly nudges eastward.
(Now through Friday) An upper trof along the East Coast moves slowly off into the western Atlantic, and meanwhile an upper ridge which extends from the southern Plains to the Great Lakes builds into the forecast region. Lows tonight and Friday night range from the mid 60s well inland to the lower 70s near the coast. Highs on Friday will be mostly in the lower 90s.
1235 AM CDT Fri Sep 20 2024 We will see quiet conditions tonight under an upper level ridge. Winds will be light with lows in the low to mid 60s. (Rest of today through Friday) Surface and upper level south central and southeastern CONUS based ridging influences are here to stay across mid state region not only through Friday, but through entire weekend. Current regional temperature trends continue to supported previously forecasted high temperature values as as upper level ridging compression clamps down on mid state region resulting in warming temperates with highs this afternoon still looking to range on the seasonally warm side upper 80s to lower 90s, mid 80s Cumberland Plateau Region. Highs on Friday will even be warmer, ranging low to mid 90s, mid 80s to around 90 for locations just west of and across Cumberland Plateau Region.
1008 PM CDT Thu Sep 19 2024 Wx map shows weak high pressure ridge extending from East Texas/Louisiana eastward, giving a weak pressure gradient over the region. Lows in the lower to mid 70s. 08/DML (Tonight through Saturday night) All indicators (satellite, radar, area observations) point to the same conclusion: it's dry and hot with only fair-weather cumulus to be seen! Temperatures have warmed into the low to mid 90s, but with dewpoints mixing down into the low 70s, apparent temps are topping out from 97 to 101F. High pressure regime continues into Friday and Saturday with similar weather: hot as temperatures hit the low to mid 90s, but dry with no precipitation anticipated.
A trough moving across Canada will then force a cold front down across our area late today into the evening with winds turning to the north. Highs Saturday will be mainly 60-65 with 40s in the high country.
412 AM EDT Fri Sep 20 2024 High pressure and ridging build into the area today, bringing warmer temps and limiting rain chances to mainly the northern Midlands.
740 AM EDT Fri Sep 20 2024 A backdoor cold front will bring a slim chance for some light rain showers today. We are on the subsident side of low pressure, but as high pressure builds south of Newfoundland towards Quebec Province, a backdoor front will slide southwest. Highs will start to come down as cooler air begins to infiltrate. On Saturday, a little wrap around moisture from coastal low pressure near the 40 N, 70 W benchmark may rotate into southern Vermont and parts of the Adirondacks.
Strong negative height anomalies continue to persist across southern California, as the main circulation with the longwave trough is nearing the L. This drier air will limit shower and thunderstorm potential as the strong dynamics with this trough would otherwise provide better potential across the region. As such, the main activity is expected to be limited primarily to areas of best dynamics as the upper level low begins to migrate eastward, which looks to remain along the northern fringes of the forecast area today and tonight. Gusty winds look to continue further west as well across the favored higher terrain areas and eventually into the lower deserts of the Imperial Valley this evening. Otherwise, temperatures will be noticeably cooler, as the main low center will migrate across the region over the next couple of days.
545 AM CDT Fri Sep 20 2024 (Today and tonight) Expect hot and humid conditions today as a strong upper level high pressure ridge(current 500 MB temperatures around 0 deg C) remains over the Southern Plains.
620 AM CDT Fri Sep 20 2024 (Today through Saturday) Key Messages: - Moderate to major heat risk today Water vapor imagery this morning reveals upper level ridging anchored across the region. A similar story is in store on Saturday as the upper ridge remains in control.
930 AM EDT Fri Sep 20 2024 High pressure remains in control through Friday promoting mainly dry and mild conditions.
500 AM MDT Fri Sep 20 2024 UPDATED AVIATION SECTION A cold front will bring breezy to windy conditions and scattered showers today followed by a dry and cooler day on Saturday.
In the low-levels, light/variable-calm flow exists withing a broad region of high pressure extending from New England southwestward into the northwestern Gulf Coast. Although a brief shower may occur across the higher terrain of northeast AL, POPs in this region remain very low (10% or less).
The low level stratus deck is holding strong over NW and West Central Minnesota this morning between 2000-3000ft still. The residual trough axis is passing through the Northern Plains this morning creating a low stratus deck and transition from a southwest flow to a dry westerly flow. Today and Saturday, The northern plains will remain stable today with cooler temperatures in the crisp 70's.
640 AM CDT Fri Sep 20 2024 Today and Tonight: The near term forecast is one of persistence as ridging surface and aloft will remain dominant through tonight. This will help result in dry weather and warmer than normal temperatures. This high will change very little through tonight and maintain a dry northerly flow aloft over our CWA. Together these features will help temperatures top out warmer than normal again this afternoon; in the lower 90s.
The residual trough axis is passing through the Northern Plains this morning creating a low stratus deck and transition from a southwest flow to a dry westerly flow. Today and Saturday, The northern plains will remain stable today with cooler temperatures in the crisp 70's.
638 AM CDT Fri Sep 20 2024 (Today through Saturday) Strong mid-level ridging will remain anchored over Texas and northern Mexico through the period. Tonight will be warmer than normal with lows in the the mid to upper 70 and the lower 80s.
UPDATE The low level stratus deck is holding strong over NW and West Central Minnesota this morning between 2000-3000ft still. The residual trough axis is passing through the Northern Plains this morning creating a low stratus deck and transition from a southwest flow to a dry westerly flow. Today and Saturday, The northern plains will remain stable today with cooler temperatures in the crisp 70's.
(Today through Saturday) High pressure and dry conditions will persist through the short term period.
Expect fairly similar conditions today as yesterday, as a weak trough extends down across the US east coast, including the Florida peninsula. Overnight lows will be in the low to mid 70s. As high pressure settles into the Appalachians, northeast winds freshen to 8-13 KT today through the weekend.
Expect a few to scattered cumulus this afternoon, but otherwise no impact weather as a surface to 8h ridge of high pressure drifts southeast through the TN Valley.
342 AM MDT Fri Sep 20 2024 A cold front will bring breezy to windy conditions and scattered showers today followed by a dry and cooler day on Saturday.
651 AM CDT Fri Sep 20 2024 (Today through Saturday Night) Upper level ridging will continue, keeping calm and warmer than normal weather over SE Texas.
Temperatures are expected to climb rapidly into the day today with upper ridging and surface southerly flow under high pressure. This will act to cool upper levels and keep daytime highs slightly cooler than the day prior, but the main question remains severe potential. The later the passage time, the more the wave will be able to utilize instability, and thus, the higher chance of severe weather.
645 AM EDT Fri Sep 20 2024 High pressure and ridging build into the area today, bringing warmer temps and limiting rain chances to mainly the northern Midlands.
628 AM CDT Fri Sep 20 2024 (Today through Saturday afternoon) Much of the area will remain under the influence of high pressure over central Texas today. Clear to partly cloudy skies and southerly winds will send highs into the 90s for all but the higher elevations in the CWA. A deep upper low over the western United States will create enough instability in the western fringes of the area that isolated to widely scattered thunderstorms will be possible from southeastern New Mexico and into the Big Bend which is the only area that could see rainfall today. Things change Saturday as the upper low moves east and closer to New Mexico and West Texas.
(Today through Saturday) Strong mid-level ridging will remain anchored over Texas and northern Mexico through the period. Tonight will be warmer than normal with lows in the the mid to upper 70 and the lower 80s.
616 AM CDT Fri Sep 20 2024 (Today through Saturday) An impressive 500 mb ridge will become centered over South Texas today with a ridge axis extending to the northeast. Similar conditions are expected Saturday as the ridge slowly nudges eastward.
This is as trough moving off the Northeast coast and associated boundary sagging south continue to exit the area. At the same time, high pressure begins to build from the north supporting north to northeasterly winds along with drier air across the Sunshine State today. As a result, showers and storms will be isolated to scattered this afternoon with the highest chances for areas over the interior and south of the I-4 corridor. High pressure begins to build in from the north into the weekend keeping north to northeast up to 15 knots.
619 AM CDT Fri Sep 20 2024 (Today and tonight) Current water vapor imagery depicts the upper level ridge and dome of high pressure positioned over southwestern Texas. By this afternoon the upper level ridge is expected to track southeastward as the upper level low off the southern CA coast begins to track into the desert southwest region this afternoon. In addition, mid-level Pacific moisture wrapping around the center of the high pressure system will also creep into portions of the far southwestern Texas Panhandle this afternoon.
Dry, mostly sunny/clear, low-to-no-impact weather is forecast to continue into this weekend as several low pressure systems affecting the western US all avoid our area.
A weak front will likely bring a decaying/scattered line of showers and a few storms beginning near the end of the near term period west of I-70 as our mid-level ridge begins to flatten. H5 ridge in place to start the period will quickly propagate eastward through the end of the weekend. How quickly this ridge shifts eastward will be important to monitor because in its wake, a robust, elongated trough will begin to carve its way through the Midwest.
1048 AM EDT Fri Sep 20 2024 A backdoor cold front will bring a slim chance for some light rain showers today. We are on the subsident side of low pressure, but as high pressure builds south of Newfoundland towards Quebec Province, a backdoor front will slide southwest. Highs will start to come down as cooler air begins to infiltrate. On Saturday, a little wrap around moisture from coastal low pressure near the 40 N, 70 W benchmark may rotate into southern Vermont and parts of the Adirondacks.
(Tonight through Saturday night) Key Messages: - Low to medium chance for coastal flooding this weekend Mid to upper level ridging is expected to continue through tomorrow night.
The low pressure system has moved off the eastern coast to the Atlantic while the dome of high pressure continues to shift eastward. In between this low pressure and high pressure system a wedge has setup over the northeastern portion of the area which has allowed for temperatures to be slightly cooler in that area. Temps up to the upper 80s/low 90s are currently on track today except for the northeast GA mountains where temps should reach the low to mid 80s.
1236 PM EDT Fri Sep 20 2024 High pressure remains in control through Friday promoting mainly dry and mild conditions.
The Heat Advisory appears good area/impact wise for now, with the only concern being areas where the mid cloud and precipitation may keep the higher temperatures from being realized.
Broad mid-level ridging remains centered over South-Central Texas today while troughing was evident over the Eastern Seaboard well to our east. High temperatures will range from near 90 in the higher terrain east to the low 90s west and central. Low temperatures will range from the low 60s northeast to the upper 60s south and west. Broad mid-level ridging will become more elongated with time through the day on Saturday as it extends further to the northeast over the forecast area. High temperatures will range from near 90 in the higher elevations east to the mid 90s far west.
Forecast dries out completely just in time for the weekend, with high pressure dominating. Weak high pressure basically east of the Appalachians remains in control this afternoon although the overall column continues to show some decent moisture.
Our weather will be quiet, with cooler temperatures today behind yesterday's passage of a dry front. The one exception will be warmer temperatures at Brookings (expected to reach the lower 80s) with downslope warming of easterly winds.
Ridging aloft and at the surface continue to control the weather pattern across the region, resulting in hot and humid conditions. Similar weather conditions to today can be expected for Saturday as high pressure remains over us. Highs will climb into the low to mid 90s with overnight lows mainly in the upper 70s.
1119 AM EDT Fri Sep 20 2024 High pressure and ridging build into the area today, bringing warmer temps and limiting rain chances to mainly the northern Midlands.
137 PM EDT Fri Sep 20 2024 A backdoor cold front will bring a slim chance for some light rain showers today. We are on the subsident side of low pressure, but as high pressure builds south of Newfoundland towards Quebec Province, a backdoor front will slide southwest. Highs will start to come down as cooler air begins to infiltrate. On Saturday, a little wrap around moisture from coastal low pressure near the 40 N, 70 W benchmark may rotate into southern Vermont and parts of the Adirondacks.
- One more warm day Saturday with highs possibly reaching (or exceeding) 90 degrees before a trend to cooler temperatures.
1208 PM CDT Fri Sep 20 2024 (Today through Saturday afternoon) Much of the area will remain under the influence of high pressure over central Texas today. Clear to partly cloudy skies and southerly winds will send highs into the 90s for all but the higher elevations in the CWA. A deep upper low over the western United States will create enough instability in the western fringes of the area that isolated to widely scattered thunderstorms will be possible from southeastern New Mexico and into the Big Bend which is the only area that could see rainfall today. Things change Saturday as the upper low moves east and closer to New Mexico and West Texas.
1226 PM CDT Fri Sep 20 2024 (Today and tonight) Expect hot and humid conditions today as a strong upper level high pressure ridge(current 500 MB temperatures around 0 deg C) remains over the Southern Plains.
An H5 ridge centered over texas with the axis stretching well into the northeast will continue the northwesterly flow aloft promoting a drying trend in the mid-levels. As a result temperatures will be slightly warmer than previous days by several degrees, with high temperatures in the low to mid 90s across the CWA. /KP/ Today and Tonight: The near term forecast is one of persistence as ridging surface and aloft will remain dominant through tonight. This will help result in dry weather and warmer than normal temperatures. This high will change very little through tonight and maintain a dry northerly flow aloft over our CWA. Together these features will help temperatures top out warmer than normal again this afternoon; in the lower 90s.
1244 PM CDT Fri Sep 20 2024 (Today through Saturday) Key Messages: - Moderate to major heat risk today Water vapor imagery this morning reveals upper level ridging anchored across the region. A similar story is in store on Saturday as the upper ridge remains in control.
1230 PM CDT Fri Sep 20 2024 (Today through Saturday) Strong mid-level ridging will remain anchored over Texas and northern Mexico through the period. Tonight will be warmer than normal with lows in the the mid to upper 70 and the lower 80s.
(Now through Saturday) Dry conditions will persist through the forecast period as upper troughing pushes off the east coast and high pressure builds in. A rather stout upper trough extending from the Florida Peninsula northeast across the eastern seaboard will continue to lift northeast into the Atlantic. In its place, high pressure over central Texas will continue to nose into the deep south brining dry northerly flow across the area.
- Strong cold frontal passage tonight into Saturday morning creating cooler and windy conditions for Saturday.
Satellite imagery early this afternoon is showing a trough of low pressure moving through western Canada north of Montana and the Idaho Panhandle. South of the low, a dry cold front is moving through western Montana. Snow levels behind the cold front will drop to about 6500 feet, so any precipitation that develops will produce a dusting of snow on the higher peaks in the park. High pressure will build back for this weekend. Cooler overnight low temperatures have prompted Frost Advisories for the valleys of west-central and northwest Montana that have not seen freezing weather so far this year.
1229 PM CDT Fri Sep 20 2024 (Today through Saturday Night) Upper level ridging will continue, keeping calm and warmer than normal weather over SE Texas.
(Tonight through Saturday night) A 591 dm ridge remains centered over northeastern Mexico and south Texas early this afternoon. Showers look less likely Saturday as the high moves pretty much right over the top of us.
A cold front will bring breezy to windy conditions and scattered showers today followed by a dry and cooler day on Saturday.
Temperatures are on track to reach the low to mid 90s this afternoon for the majority of the area.
1054 AM MDT Fri Sep 20 2024 Cold front was pushing S thru NW MT late this morning toward KTFX. A trough moving across Canada will then force a cold front down across our area late today into the evening with winds turning to the north. Highs Saturday will be mainly 60-65 with 40s in the high country.
Tomorrow will be a bit more bearable, temperature wise, as an upper low approaches from the west. The low is currently sitting over southern California and is forecast to push eastward towards the four corners region tomorrow. As it does this, the ridge will start to break down slightly. The precipitation ahead of the previously mentioned upper low is expected to remain to our north and west tomorrow, leaving us with a dry forecast for Saturday afternoon.
(Tonight through Saturday night) The high pressure that has been parked in the middle layers of the atmosphere is allowing for similar conditions over Deep South Texas to persist.
A low pressure system moving through southern California will continue to produce scattered to numerous showers and thunderstorms through tonight. Impacts in the way of locally heavy rain(flooding), gusty winds and hail from thunderstorms associated with the slow moving upper low will stay with us through tonight. Upper low presently east of Los Angles will continue to slowly trudge east through southern California into early this evening. The low will then start to accelerate east across western Arizona late tonight/Saturday. Intermountain West will be under a dry northwest flow early in the week with GEFS/EPS both showing a weak open trough dropping southeast across Utah/Colorado.
159 PM EDT Fri Sep 20 2024 High pressure remains in control through Friday promoting mainly dry and mild conditions.
1152 AM CDT Fri Sep 20 2024 (Today through Saturday) An impressive 500 mb ridge will become centered over South Texas today with a ridge axis extending to the northeast. Similar conditions are expected Saturday as the ridge slowly nudges eastward.
/NEW/ /Through Saturday/ Anomalously warm temperatures will continue through Saturday as a strong 592-593 dam ridge (approaching the 90th %tile of climatology) remains anchored over the state of Texas. Temperatures elsewhere will fall into the lower 70s.
205 PM MDT Fri Sep 20 2024 A few showers had developed N of the forecast area, ahead of the approaching cold front this afternoon. A few snow showers are possible in the high elevations of the Beartooths. It will be cooler behind the front with highs in the 60s. Weak ridging will keep dry weather over the area Sat.
A low pressure system moving across Arizona will bring cooler temperatures, breezy winds, and chances for showers and thunderstorms tonight through Saturday. Warmer and drier weather is expected to return for much of the upcoming week. An upper level closed low is near San Diego this afternoon with showers and thunderstorms developing across southern California and Nevada. The low will gradually move east into Arizona tonight, and then northeast across the state on Saturday before exiting Saturday evening. On Saturday, the low is expected to be centered over central Arizona in the morning and track northeast through the day. Another result of the trough will be colder temperatures Saturday, which have continued to trend a bit cooler and will be the coldest yet this season. Dry conditions return Saturday evening when the low and trough axis move east of Arizona.
