Aikyam-Lab/Synoptic-Bench huggingface dataset:
Water vapor imagery and stream flow indicates a nearly stationary upper low over southeast TX, an upper high over the Carolinas, with southerly flow aloft advecting high level moisture into the region. Dew points are in the lower to mid 60s, with temps in the mid 60s to around 70. The 3km NAM and HiResARW indicate some development possible along the higher terrain this afternoon, but will hold off on this given the cap.
An upper low positioned over northern CA this morning will track to northeastern NV by Monday afternoon. Showers will stay close to the low center this morning, focusing over southeast Oregon (mostly southern Harney and Malheur counties) and points south and west. Precipitation expands into southwest Idaho this evening as the low turns eastward. Periods of rain and high elevation snow will continue through Monday as the low lifts into northeast NV. Areas that are dry this morning will see slightly warmer temperatures today, cooling 5-10 degrees on Monday.
417 AM EDT Sun Jun 11 2017 A large ridge of high pressure will continue to build across the Great Lakes and Ohio valley through this week.
Unseasonably cool temperatures will persist across the region through Sunday as an upper level low arrives over northern California.
1123 PM MDT Sat Jun 10 2017 Southwest flow aloft over the area will continue tonight and Sun, as an upper low moves slowly southward from the Pacific Northwest coast into northern CA. Also, with the very warm temps, rapid snowmelt will continue in the high country which will keep rivers and streams running high and fast.
156 AM EDT Sun Jun 11 2017 Sub-tropical high pressure will expand across the southeastern U. Heat indices will be about the same with dewpoints in the low 60s this afternoon and light southwesterly winds at around 5 kts are expected.
233 AM CDT Sun Jun 11 2017 Developing low pressure over eastern Kansas has helped to intensify a strong southerly LLJ over the area. This strong LLJ is expected to increase low levels a few degrees Celsius and give the area a boost of 3-4 degree in the high temperatures for Sunday from what they were yesterday leading to highs in the low 90s throughout the region. This increase in temperatures along with dewpoints in the lower 70s will result in heat indexes in the mid to upper 90s for Sunday afternoon creating the possibility of some heat related issues for those outside or sensitive to heat.
405 AM CDT Sun Jun 11 2017 Early morning sfc analysis shows high pressure in place over the sern CONUS continuing to provide a light srly low-level flow off the Gulf over the forecast area this morning which is evident in regional 00z soundings as both PWAT/mean RH values continue to creep upward. Water vapor imagery shows a mid/upper-level low spinning over sern TX while some ridging is noted extending from nrn Mexico/wrn TX and up through the srn Plains. The low aloft over sern TX is progged to meander over the wrn Gulf region through the early part of the new week. This low is progged to weaken while drifting ewd across the nrn Gulf into mid-week, while soundings indicate moisture decreasing somewhat.
The ridge will begin to slowly break down early this week as precipitation chances increase for the end of the work week. Heat indices will be about the same with dewpoints in the low 60s this afternoon and light southwesterly winds at around 5 kts are expected.
351 AM EDT Sun Jun 11 2017 High pressure will build across the area today through Monday bringing dry warm weather with high temperatures both days well into the 80s.
Overnight mins in the low/mid 70s. A predominant low level southeast flow will persist across the region early this week, as ridge axis of high pressure over the west Atlantic remains north of the area. A stronger area of high pressure building down into the northeast U. shifts subtropical ridge axis farther south and across the area into late week. Another active afternoon today with isolated activity expected near coastal sites late morning through early afternoon, then the higher chances for showers and storms will shift to inland sites mid to late afternoon. Winds out of the east-southeast will veer the south- southeast later in the week as subtropical ridge axis north of the area shifts southward and across the region.
336 AM CDT Sun Jun 11 2017 Still under the influence of an upper level ridge across the SE CONUS in-conjunction with our region being displaced equatorward from the northern stream 300 hPa jet, another very warm day is in store for the Panhandles as we close out the weekend. High temperatures today will range from the low and mid 90s in the SE TX Panhandle to upper 90s and lower 100s in the western and northern Panhandles. The main upper low pressure system centered over the northern California coast on Monday will move northeast toward the northern High Plains by mid to late this week.
308 AM CDT Sun Jun 11 2017 Upper flow over the local area remains modest from the southwest with an upper low over the Pacific Northwest and weak low over southeastern Texas. At the surface, a stationary front was draped west-to-east over the northern Plains with a lee trough in eastern Colorado. Models are fairly similar in low levels warming a bit with a slightly tighter pressure/height gradients leading to a slightly warmer and windier day.
With high pressure remaining in the western Atlantic to the northeast of the area, expect east to east-southeast flow for Sunday and Monday combined with PWATs slightly above climatology.
557 AM CDT Sun Jun 11 2017 Developing low pressure over eastern Kansas has helped to intensify a strong southerly LLJ over the area. This strong LLJ is expected to increase low levels a few degrees Celsius and give the area a boost of 3-4 degree in the high temperatures for Sunday from what they were yesterday leading to highs in the low 90s throughout the region. This increase in temperatures along with dewpoints in the lower 70s will result in heat indexes in the mid to upper 90s for Sunday afternoon creating the possibility of some heat related issues for those outside or sensitive to heat.
155 AM EDT Sun Jun 11 2017 Sub-tropical high pressure will expand across the southeastern U. Heat indices will be about the same with dewpoints in the low 60s this afternoon and light southwesterly winds at around 5 kts are expected.
Expect slightly warmer temps this afternoon and similar wind speeds. By tomorrow afternoon and evening, a stray thunderstorm can't be ruled out across extreme SW OK and portions of western N TX as a few storms move off the high plains near the dryline. This is where the highest chances are expected.
403 AM EDT Sun Jun 11 2017 An upper level ridge of high pressure centered across the middle of the Atlantic continues to hold sway across the Ohio and Tennessee valleys. Lows will range from around 60 in the valleys, to the mid and upper 60s on the ridges. Highs on Monday will be similar to perhaps just a bit cooler compared to highs today. An upper level ridge will be in place across much of the SE U.
Overnight lows will be warmer and muggier than the past couple of nights with increasing moisture. Ridging will stay over the east coast through the period. Moisture will continue to move inland around the upper level high centered over the Carolinas. Highs will be in the upper 80s with lows in the lower 70s.
242 AM EDT Sun Jun 11 2017 High pressure will continue to build into the area through Sunday, maintaining fair weather, with temperatures slightly above normal. Above normal high temperatures, in the lower 90s. Upper level ridging will remain over the region through the period. On Monday, moisture will begin increasing with offshore high pressure promoting southerly flow. However, with the center of the upper ridge still over the area, the majority of shower and thunderstorm activity should remain off to the south and west of the forecast area through Monday night. High temperatures will likely be a few degrees above normal during the period with ridging in place. An upper level ridge will weaken and shift eastward through the period allowing Atlantic and Gulf moisture to push into the region.
355 AM CDT Sun Jun 11 2017 Water vapor imagery and stream flow indicates a nearly stationary upper low over southeast TX, an upper high over the Carolinas, with southerly flow aloft advecting high level moisture into the region. Dew points are in the lower to mid 60s, with temps in the mid 60s to around 70. The 3km NAM and HiResARW indicate some development possible along the higher terrain this afternoon, but will hold off on this given the cap.
West winds will increase Monday afternoon as deep low pressure organizes over the northern Rockies.
In addition, some showers and isolated thunderstorms over mostly the higher terrain from Fresno county northward.
136 AM EDT Sun Jun 11 2017 We will continue warming through the end of the weekend as deep layer ridging lingers. This pattern will hold through the start of the new work week with upper ridging weakening each day.
We'll be getting a milder start though, and 925 mb temps might be a degree or so higher, so did end up with highs a smidge warmer than yesterday. Should be mild again tonight, with lows in the low 70s most places.
Unseasonably cool upper low digging over Interior NorCal today will result in unsettled weather. Threat of showers continues overnight into Monday over the mountains of Western Plumas and the Sierra Nevada as upper low shifts into Nevada.
336 AM CDT Sun Jun 11 2017 A strong trough continues to dig over the western CONUS early this morning with a ridge building over the southeast. The southerly flow on on the eastern flank of this low will continue to advect deep moisture into the Mid-South today. The increase in moisture will bump heat indices up into the lower 90s across much of the area this afternoon. The primary concern would be brief heavy downpours given the high PWATs and slow storm motions.
616 AM EDT Sun Jun 11 2017 High pressure will build across the area today through Monday bringing dry warm weather with high temperatures both days well into the 80s.
419 AM CDT Sun Jun 11 2017 Currently residing in southwest flow on the west side of an upper level ridge.
The upper level low that brought some showers to the area the last couple of days has moved into Northern California this morning. This is far enough south to end the shower threat for the lowlands today.
532 AM EDT Sun Jun 11 2017 High pressure will bring dry weather and summertime warmth into the beginning of the new week.
210 AM CDT Sun Jun 11 2017 Upper-level trough across east Texas to support an unstable atmosphere across the region today into Monday.
645 AM EDT Sun Jun 11 2017 A warm front moves east of the region today ushering in very warm air for today and Monday across much of the area.
Surface ridging will begin to weaken over the area today with winds southwest, generally less than 10kts.
347 AM CDT Sun Jun 11 2017 A weak upper level ridge moving over the area is shifting east towards the Atlantic Ocean and eroding on its south side as inverted trough expands north from the gulf. General clockwise flow around the high pressure is beginning the bring back deep tropical moisture to the region. The GFS has reverted back to a solution showing upper ridge centered over Mexico beginning to expand east over the area mid weak. The latter part of the week still looks wet as an upper level trough swings across the midsection of the country. Caution flags will be lifted today through a portion of Monday morning as an inverted trough causes winds to rapidly rise this morning. The trough will also bring a deep moisture surge allowing sh/ts to develop this morning.
323 AM EDT Sun Jun 11 2017 Building high pressure will bring dry weather and warm weather for the start of the new week.
332 AM EDT Sun Jun 11 2017 High pressure will bring dry weather and summertime warmth into the beginning of the new week.
357 AM CDT Sun Jun 11 2017 Upper ridge over the area will continue hot weather for the region.
Strong high pressure ridge over the southeastern part of the country will hold on for another 24 hours with very warm and dry conditions through tonight.
305 AM PDT Sun Jun 11 2017 Low pressure will bring gusty winds, rain and mountain snow showers, along with very cold temperatures to the region today into Monday. A strong low pressure dropping out of eastern Pacific will bring rain and mountain snow showers along with much colder temperatures to the region today. So, this will be quite a shock to people who have already adjusted to warmer summer weather, but is not unprecedented. Recent model simulations are tracking the low in such a way that far northeast California and northwest/central Nevada will be in a prime position to receive fairly significant amounts of precipitation. It could also stay quite windy overnight tonight into Monday morning in west-central Nevada as the low pressure moves into southern Idaho.
409 AM CDT Sun Jun 11 2017 Stationary summer pattern remains entrenched across the bi-state region with mid/upper level ridging aloft and south/southwest low- level flow. You will probably begin to notice the increase in humidity as dewpoints this afternoon rise into the low to mid 60s due to the prolonged southerly surface flow.
120 AM EDT Sun Jun 11 2017 Very warm weather is ahead with highs in the upper 80s to lower 90s into midweek as an upper level ridge builds into the eastern United States.
327 AM EDT Sun Jun 11 2017 Bermuda high pressure will remain anchored off the coast through the middle of this week. A trough and cold front will approach the region late this week. High pressure both at the surface and aloft will be in full control of our weather today. While a few passing high clouds are possible from time to time, strong subsidence from the highs just mentioned will keep our weather dry.
Many valleys have dropped into the low to mid 30s, with locations such as Butte, Anaconda, and Seeley Lake being below freezing. We are still watching a cut-off low pressure system that has made it's way onshore this morning. The center of the low is still forecast to move east through southern Idaho, wrapping moisture into our region by Monday evening.
640 AM CDT Wed Mar 14 2018 High pressure over eastern Kansas will move south today toward the Southern Plains providing a period of dry weather through the short term. A broad trough over the eastern one third of the country will slowly continue to move to the east today. Winds will switch from the northwest to the southwest after sunrise today over the area in response to high pressure moving south this morning.
916 AM PDT Wed Mar 14 2018 Upper level low pressure off the Pacific Coast will drift slowly southward through the end of the week. Forecast on track with high topping out mainly in the lower-mid 50s and a few showers around the rest of the day. The main upper low will drift south over the next few days.
This morning's surface analysis shows a region of high pressure situated over SE TX. Expecting high temperatures today to again rise into the low 70s, right around normal for this time of year. High pressure over the plains should move east today.
Issued by National Weather Service GREENVILLE-SPARTANBURG SC 1134 AM EDT Wed Mar 14 2018 High pressure in the Lower Mississippi River Valley today will be in the northeast Gulf of Mexico Thursday.
1109 AM EDT Wed Mar 14 2018 High pressure is dominant with sunny skies across the region.
Unseasonably cool through Fri morning, then warmer temperatures Today. A frontal trough along the Carolina coast will push east while cold high pressure centered over the southern Plains settles to the Gulf Coast states. Hence, min RH will nudge downward with the lowest values around 20 percent over the north interior.
715 AM EDT Wed Mar 14 2018 High pressure in the Lower Mississippi River Valley today will be in the northeast Gulf of Mexico Thursday.
Morning temperatures were slightly warmer than forecast, but still calling for daytime highs near 60 across southeast Georgia and mid 60s across northeast Florida.
High pressure over the plains should move east today.
1237 PM EDT Wed Mar 14 2018 Periodic snow showers and cold temperatures are expected most of the week under upper level low pressure. Considering 12Z observed sounding at KPIT still remains favorable for snow, can only imagine that conditions are more favorable for snow in the ridges. Another cold front will swing through early Thursday morning with a reinforcing shot of cold air. This will invigorate snow showers for a majority of the lower elevations, but could lead to appreciable accumulations in the highest elevations of Tucker and Garrett Counties.
Low VFR/high MVFR stratus evident on visible just north of Lake Superior early this aftn will fill in behind the cold front early Thursday morning. Predominately northwest flow aloft remains overnight and into tomorrow as the broad trough pattern holds its grip over the Great Lakes.
Temperatures are in the lower to mid 60s. In the low levels of the atmosphere, an area of high pressure will be centered near Louisiana this afternoon. In the mid to upper levels of the atmosphere, a trough of low pressure will move eastward over the Florida peninsula today.

754 AM EDT Wed Mar 14 2018 Periodic snow showers and cold temperatures are expected most of the week under upper level low pressure. Another cold front will swing through early Thursday morning with a reinforcing shot of cold air. This will invigorate snow showers for a majority of the lower elevations, but could lead to appreciable accumulations in the highest elevations of Tucker and Garrett Counties.
938 AM EDT Wed Mar 14 2018 An amplified pattern is in place aloft across the country this morning, with a large low entering the Pacific northwest, followed by ridging across the central U. and broad troughing over the east. As we head through the day, the high will shift closer to the region, with a shot of drier air filtering in. Winds will diminish tonight through Thursday as high pressure shifts more overhead.
939 AM EDT Wed Mar 14 2018 Periodic snow showers and cold temperatures are expected most of the week under upper level low pressure. Considering 12Z observed sounding at KPIT still remains favorable for snow, can only imagine that conditions are more favorable for snow in the ridges. Another cold front will swing through early Thursday morning with a reinforcing shot of cold air. This will invigorate snow showers for a majority of the lower elevations, but could lead to appreciable accumulations in the highest elevations of Tucker and Garrett Counties.
The upper trough that is bringing some snow showers to the Southern Appalachian region will be moving away this morning.
High temps will be near normal today, even after the passage of a cold front last night. This morning the very cold upper level trough remains centered off the British Columbia coast and extends south over California. Models show the low pressure center remaining nearly stationary today, while the southern portion of the trough pivots inland following the cold front, which will cross southeast Oregon and southwest Idaho this morning.
Increasing S-SW flow forecast in the lower levels of the atmosphere today will result in gusts to between 30-35kts at KLVS and KTCC. Low level moisture trapped underneath high pressure aloft will keep skies mostly to partly cloudy today but temperatures will be several degrees above seasonal averages. The high shifts east of the state later today and southwest flow aloft moves in.
Issued by National Weather Service GREENVILLE-SPARTANBURG SC 929 AM EDT Wed Mar 14 2018 High pressure in the Lower Mississippi River Valley today will be in the northeast Gulf of Mexico Thursday.
Expect windy conditions and cooler temperatures today, along with a slight chance of showers.
407 AM EDT Sun Aug 13 2017 High pressure over the Midwest will move slowly east over the next couple of days providing fair weather.
/issued 433 AM CDT Sun Aug 13 2017/ The latest upper air analysis and water vapor imagery shows flat ridging extending acrs southern TX and the northern Gulf coast. A disturbance was translating east acrs the Red River valley on the northern periphery of the ridge, producing a large convective complex that is traveling along a west to east oriented quasi- stationary frontal boundary acrs northeast TX/southeast OK into southern AR and northern LA. 24 Little change to the fcst for the upcoming week as flat ridging will persist acrs the northern Gulf coast. By the middle to latter part of the week, ridging is expected to build some over the region. Aftn temperatures will run close to seasonal normals through the week with highs in the lower 90s, outside of any areas that see cooler temps from showers.
Model soundings and plan views do however suggest the development of weak instability Mon afternoon, primarily in the vicinity of Saginaw Bay and the higher terrain in north central Lower Mi.
310 AM EDT Sun Aug 13 2017 High pressure builds in today and shifts offshore on Monday. Weak low pressure passes to the south Monday night.
335 AM EDT Sun Aug 13 2017 South Florida continues under a weak flow pattern surrounding Atlantic high pressure. To our north, a mid-level trough continues to meander along the eastern seaboard of the United States.
No major changes were needed as building high pressure under weak upper troughing will suppress precip and support seasonable temperature.
326 AM EDT Sun Aug 13 2017 A cold front will settle into NC this morning, where it will then stall and remain quasi-stationary through the middle of the upcoming week. Then between 06 to 12z, the arrival of the cold front into the area from the north- northwest will result in a continued chance for showers and storms, primarily north of highway 64. Mild overnight lows in the lower to mid 70s. The sfc cold front will stall in vicinity of highway 64 as it becomes parallel to the flow aloft. The upper level pattern will be characterized by high pressure over the deep south and weak cyclonic flow over and north of Central NC.
337 AM EDT Sun Aug 13 2017 A weakening cold front will stall across North Carolina today. then will push back north tonight into Monday as a wave of low pressure moves along the boundary.
413 AM MDT Sun Aug 13 2017 A short wave trough aloft sweeps through the region this afternoon and evening.
220 AM EDT Sun Aug 13 2017 A cold front and associated upper-level trough are moving through our region this evening. Cooler and drier air should replace the humid air mass. A weak trough will dominate our weather most of the week as a ridge builds over the southern US.
Given the colder start to the day it will likely be a few degrees cooler than today. The drying in the low levels should limit any fog redevelopment Sunday night/Monday morning. High pressure will be centered over the Forecast area by tomorrow night and linger through the period. The high slides East of the area late Monday allowing for a gradual warmup.
High pressure responsible for the drier air will continue to influence our weather tonight with dry weather continuing. Temperatures will be a few degrees cooler than yesterday. Upper trough over southwest Quebec/southeast Ontario will move east this morning and there may be a few showers across the far northern tiers of New York and Vermont through about mid-morning before the upper trough moves east and drier air moves in.
135 AM EDT Sun Aug 13 2017 High pressure through Monday.
435 AM EDT Sun Aug 13 2017 A cold front and associated upper-level trough are moving through our region this evening. Cooler and drier air should replace the humid air mass. A weak trough will dominate our weather most of the week as a ridge builds over the southern US.
