Aikyam-Lab/Synoptic-Bench huggingface dataset:
After collaboration with surrounding offices, will again opt to hold off on any headlines for now since the lowest humidity values are in a spatially limited area near the South Dakota border. There are still differences in the models regarding thermal profiles with this system, but there is general agreement in higher chances for precipitation and cooler temperatures. Main aviation highlight will be gusty westerly winds increasing behind a cold frontal passage Sunday.
A strong U/L ridge over the southern plains will extend across the Gulf of Mexico and Florida peninsula through Monday. A L/W trough approaching the Mississippi river valley will gradually push east to the mid Atlantic coast on Monday and will weaken through the period. At the surface, weak high pressure will hold over west central and southwest Florida through Monday with light boundary layer flow across the area.
655 AM EDT Sun Sep 18 2016 A cold front will then slowly progress through the region this afternoon and evening, with additional showers and thunderstorms at times.
Otherwise, expanding upper ridge should dominate area weather into the mid-late work week and keep the area mostly dry & hot. Rain chances increase going into the weekend as high pressure loses its grip and an upper trof approaches. but the forecast for the coming week will be dominated by the fairly strong upper ridge building over the South- ern Plains.
314 AM CDT SUN SEP 18 2016 A minor upper level trough was moving east across the central portions of the state early this morning. The upper trough axis will shift eastward across the CWA through 12Z. I suppose as the H5 trough moves east across the CWA there could be a few sprinkles or light showers across the eastern counties as well. Today, the upper trough will move east-southeast into the mid and lower MS river valley. Tonight will be mostly clear with lows in the lower to mid 60s. By Monday morning, a mid level ridge will be located over the southern CONUS while a trough axis is located along the east coast.
Aloft, a broad scale trough entering central TX/OK will shift east across the northern half of our region on Sunday so showers and storms will increase from late morning through the afternoon hours along and north of the I-20 corridor. For now, have only added TEMPO thunder at TXK/ELD where confidence is higher but did include VCTS at the I-20 terminals as well for late Sunday morning through the afternoon as this trough shifts overhead. as we await the aforementioned upper trough passage after daybreak Sunday morning which should drive the ongoing convection over the TX/OK Panhandles which should accelerate SE into SE OK around 12Z. Did tweak min temps tonight down a degree or two per the current trends and potential for cooler outflow winds.
A trough of low pressure will dig into the Southeastern States creating a focus for convection in addition to diurnal instability and sea breeze interactions.
An unseasonably strong upper ridge will then build over the southern Plains early this week and perisst through the work week, resulting in afternoon temperatures nearing record levels in some places.
Strong west winds aloft will continue to support gusty winds at the higher elevations through today, and then diminish. Afternoon temperatures should remain relatively steady and mild, but morning lows on Monday morning should be much cooler than Sunday morning, due to fewer clouds and lighter winds.
Conditions to improve by mid morning with partly to mostly sunny skies and temps warming up into the low 80s.
Next chance for precipitation comes on Monday as a weak cold front settles over the forecast area.
454 AM EDT SUN SEP 18 2016 High pressure will retreat from off the New England coast today.
355 AM EDT SUN SEP 18 2016 High pressure will retreat from off the New England coast today.
247 AM MDT SUN SEP 18 2016 Current surface map shows low pressure across Saskatchewan with trof into the northern plains. 130kt jet streak located across the Pacific Northwest will move eastward along the Canadian border today, allowing weak cold front to slip through the western Dakotas.
We'll stay in the low to mid 70s for the remainder of the night. A weak short wave trof moving through the Ohio Valley region was tapping into some very deep tropical moisture over the Central Gulf States. Areas east of I-65 have seen very little rainfall today, but the upper level forcing associated with the short wave trof will eventually shift into areas east of I-65 later this afternoon and evening. The loss of daytime heating will result in the areal coverage decreasing significantly after sunset, but small rain chances will continue throughout the night as the main short wave trof approaches from the northwest.
509 AM EDT SUN SEP 18 2016 A warm front will cross the region today.
High pressure in the middle layers of the atmosphere will prevail across deep south Texas and the Rio Grande Valley through the next 24 hours. High pressure is in control of the weather and VFR conditions are generally expected. /issued 246 PM CDT SAT SEP 17 2016/ SHORT TERM (Now through Sunday night): H5 ridge continues to build aloft as active pattern remains well to the north. Sunday will be similar to today, as the H5 ridge dominates the region.
319 AM MDT SUN SEP 18 2016 A ridge of high pressure aloft will remain over the region through tonight. It will be 7-10 degrees warmer than yesterday with relative humidities dropping into the teens this aftn.
With the low approaching, we have seen an uptick in shower activity and in fact, some better updrafts have developed leading to a few widely isolated storms. This low will continue to track north and east this morning with precipitation continuing to expand in coverage along the front as it moves east. with highs back into the lower 80s with much lower humidity. A cold front will bring showers to the area through the overnight hours and on Sunday. Pattern overall, would favor a stratus as the low level winds go more northeast with time, keeping potential stratus locked in tonight.
1038 PM PDT Sat Sep 17 2016 An early Autumn Pacific storm system has arrived with wet conditions, breezy winds and cooler temperatures expected.
337 AM CDT SUN SEP 18 2016 At the surface, TD Julia remains off the Carolina coast, while weak high pressure is centered over the Appalachians.
319 AM PDT SUN SEP 18 2016 A warming trend will continue through Monday as high pressure prevails.
Currently, under sunny sky/light wind conditions, temperatures are warming through the 70s, and in some spots up into the low to mid 80s. There is a cold front forecast to sweep through the CWA on Sunday with little fan-fare other than an increase in wind speed to 20 to 30 mph with some higher gusts from the northwest across portions of north central South Dakota by early Sunday afternoon. Cooler air will move into the region for Monday with 850mb temperatures falling about 6C by 12Z Monday. Ceilings will remain fairly high, between 8 and 10kft, but should be low enough to get some sprinkles thanks to the cooler airmass.
The mid level ridge will hold over the region today and then shift to the west into northern Mexico into southwest Texas on Monday.
The cool air behind the cold front will enhance the wind strength.
332 AM CDT SUN SEP 18 2016 500 mb short wave trough moving east along the International border today.
326 AM CDT SUN SEP 18 2016 Latest analysis shows the remnant inverted trough axis and mid level weakness has moved eastward and is located over Southeast Louisiana into the Gulf South. Radars so far less active than 24 hours ago, with a few nocturnal showers extending from the lower Acadiana coast into the coastal waters, where better moisture is located. With clearing skies, light winds, and more stable conditions behind the trough, patchy fog is forming in areas with residual low level and ground moisture. This system will continue to absorb and push the old inverted trough and associated deep moisture to the east- northeast. Upper level ridging centered over Texas will build eastward behind the short wave and strengthen over the next few days.
700 AM EDT SUN SEP 18 2016 A cold front moves slowly across the area today. High pressure for the work week. but I did slow down the PoP as upper trough and then the accompanying cold front come through today and tonight. Cold front will lag behind the upper trough and not pass until late tonight or early Monday morning. The low level moisture will remain overnight and low temperatures will still be in the low to mid 60s. Axis of 500 hPa trough will pass central WV around 15z Monday morning. has slowed the eastward progression of low level moisture in the wake of the trough. minor adjustments have been made to Sky and PoP forecast for the Monday morning hours over central WV and the higher terrain.
329 AM EDT SUN SEP 18 2016 A cold front will approach from the west this morning then stall over the area through Monday.
558 AM EDT SUN SEP 18 2016 A poorly defined slow moving cold front will move east across the area today. High pressure will build in tonight and Monday.
With the low approaching, we have seen an uptick in shower activity and in fact, some better updrafts have developed leading to a few widely isolated storms. This low will continue to track north and east this morning with precipitation continuing to expand in coverage along the front as it moves east. with highs back into the lower 80s with much lower humidity. Prevailing westerlies across the northern tier of states will carry a cold front along which will settle southeast and lose identity and momentum as it runs under the upper ridge.
Meanwhile, the lower valleys continue to experience rain shadowing due to stronger winds aloft at mountain top level.
432 AM EDT Sun Sep 18 2016 A cold front will then slowly progress through the region this afternoon and evening, with additional showers and thunderstorms at times.
Downtrend in shower coverage will continue this afternoon into early this evening across ne IN/nw OH as deep moisture plume tied to pre-frontal trough exits east.
159 AM EDT Sun Sep 18 2016 Showers and thunderstorms will move through central New York and northeast Pennsylvania overnight ahead of a warm front. A cold front will then slowly progress through the region Sunday, with additional showers and storms at times.
SHORT TERM (Now through Monday): 500mb ridge centered nearly overhead this morning will shift slightly west over the Texas Big Bend region through the forecast period.
Deep layer moisture will continue to increase across the region ahead of an approaching upper trough and surface cold front.
351 AM CDT SUN SEP 18 2016 Upper level analysis shows a cutoff low slowly pushing southwest off the coast of southern Cal while the main upper trough swings east through the midwest states.
Warm advection southwest flow and mixing 85h temps of near 11C east to 14C west to sfc should yield highs today in the low to mid 70s, warmest west half. Expect lows generally in the upper 50s to the lower 60s with the warmest readings along the Great Lakes shorelines. Most of the uncertainty revolves around the location and intensity of an upper low that will close off over the northern plains or in south central canada.
144 AM EDT SUN SEP 18 2016 A slow moving cold front across the Central Lakes will move across the forecast area tonight. High pressure will build across the area Sunday night. Cooler and drier air move into the area from the West Sunday night as high pressure builds over the area.

This is due in part from increasing moisture interacting with higher terrain, however there is also an upper level low moving onto the Baja of Mexico that is increasing instability. The highest rain chances will be closer to the low in the Big Bend region and diminishing farther north.
A cold front will pass through the area Saturday morning, eventually clearing the clouds and fog late in the morning. The 7 am EDT regional surface analysis showed a cold front from northeast MS to the coastal waters of TX. Vapor imagery and upper air data showed a positive-tilted trough approaching from the west. This system is expected to weaken a bit as it moves into a region with less favorable thermodynamics, but we are still forecasting high rain chances across most of our area this afternoon given the expected Q-G forcing and moisture ahead of the approaching trough.
