Aikyam-Lab/Synoptic-Bench huggingface dataset:
Daytime temperatures will still warm to near or slightly above 90 degrees, but the lower dewpoints will result in much lower heat index values compared to the last couple of weeks. /issued 515 AM CDT Sun Jul 30 2017/ Sfc cold front has pushed south of our terminal airspace this morning with post frontal winds mostly from the E to NE near or less than 10kts. IR Imagery this morning showing that the low levels of the atmosphere still containing a little moisture, in the form of 4-6kft cloud cover across portions of NE TX into SW AR and extreme NW LA. Deep northerly flow aloft and broad upper troughing over great lakes region will keep this new somewhat cooler and drier pattern across the area.
GOES imagery indicates the deep east coast trough continues to dig with the apex of best drying and descent into southeast Georgia. Otherwise the anticyclonic turning associated with low level ridging across the southern Bahamas appears to have shunted the deeper dry air, of precipitable water 1. Early isolated cumulus congestus witnessed data has degenerated into humilis over the Lower Keys for the time being.
Upper high over the Panhandles early today will shift south by tonight and then west by Monday across far West Texas and the southern Rockies.
Strengthening high pressure aloft across the Great Basin will bring a gradual warming and drying trend to the region through the middle of the upcoming week. Water Vapor Satellite shows a ridge centered over Nevada. With the anticyclonic flow around the Nevada ridge, gradual drying continues from northwest to southeast as evident by Precipitable Water, Dewpoint, LCL height, and DCAPE trends. The upper ridge expanding north and west across the western CONUS today will eventually form two centers across the region. The areal coverage will likely remain limited, with most of the activity tied to the higher terrain. Beginning late Monday the high center to the west of Utah will become the dominant feature, with a drier north-northeast developing across northern Utah.
/issued 340 AM EDT Sun Jul 30 2017/ Today: Strong low pressure observed in the latest wv imagery to the northeast portion of the Mid-Atlantic states with a frontal boundary extending southwestward into the FL panhandle. This has helped push the influence of the high pressure towards the east over the Atlantic waters.
1247 PM EDT Sun Jul 30 2017 Hydro High pressure will bring fair weather with low humidity into the middle part of the week.
922 AM CDT Sun Jul 30 2017 High pressure in the Mid Missisissippi valley will stay in control over the area through Monday afternoon. Northwest flow aloft will continue over the region with a trough over the northeast US and a ridge covering most of the western part of the country. Northwest flow aloft continues with a trof over the eastern US and a large ridge of high pressure over the weatern US.
1016 AM MDT Sun Jul 30 2017 Watching cumulus develop over the higher terrain on satellite and webcams, which matches the forecast of possible storms developing by noon over the mountains. Forecast soundings show erosion of any convective inhibition (CIN) over the mountains by the noon hour, and 2-3 PM over the Cheyenne Ridge and perhaps the Palmer Divide. Those storms should then begin to pull off the higher terrain and spread southeast as the cap weakens/erodes across the adjacent plains. High temperatures today will be a couple degrees warmer, but still a few degrees below normal. Locally heavy rain will continue to be a threat, but it is difficult to pinpoint which areas will be at the highest risk. With moisture levels in the airmass near the annual maximum, temperatures are going to be held in the lower and mid 80s.
/issued 350 AM CDT Sun Jul 30 2017/ An upper level high remains over West Texas this morning while a weak surface boundary has pushed southwest into the Permian Basin causing winds to back from a more easterly direction. Tomorrow the upper high shifts back to the west where it will remain for the remainder of the week. The best chance for rain will be in the first half of the week when a weak cold front, reinforced by convection, slowly moves south into the Trans Pecos region. Highs drop into the 80s for many locations Tue-Thu mainly due to rain and increased clouds as opposed to any cold air advection behind the front, so if the rain doesn't materialize then highs could be a few degrees warmer than currently forecast.
1137 AM EDT Sun Jul 30 2017 High pressure will provide dry weather and seasonable temperatures through Monday. Another great day on tap for CNY/NEPA, with sunny skies and low humidity, thanks to high pressure expanding down from eastern Canada. Large area of high pressure over the central Great Lakes will make for another beautiful summer day. Continue under an upper level trough this period.
1240 PM EDT Sun Jul 30 2017 High pressure centered over the Midwest today will settle toward the Ohio valley tonight through Monday. High pressure remains anchored over the upper midwest, tucked beneath lower amplitude mid level northwest flow defining the periphery of broad upper ridging stretching back through the central/western conus. Surface ridging broadens with time to encompass much of southern lower Michigan, a response to persistent positioning of weakly confluent northwest flow overhead. Any further airmass modification appears limited given retention of weak northwest to west low level flow and continued displacement of the upper ridge axis to the west.
950 AM EDT Sun Jul 30 2017 Dry weather is expected through today as high pressure remains over the North Country. A weak frontal system will drop south from Quebec and could provide some isolated showers generally over the higher terrain Monday afternoon.
728 AM EDT Sun Jul 30 2017 Aviation High pressure will bring fair weather with low humidity into the middle part of the week.
937 AM EDT Sun Jul 30 2017 High pressure with cooler and drier air prevails for the remainder of today and through mid week.
Very hot and dry conditions for interior locations, as a strong ridge of high pressure builds over the West Coast and persists throughout the week. A strong ridge of high pressure will be building over the West Coast.
1231 PM EDT Sun Jul 30 2017 A ridge of high pressure will keep dry and mostly sunny conditions today. High temperatures will reach into the lower 80s.
Additionally, drier air is beginning to filter in behind the front (dew points in the low 60s at Crockett compared to upper 70s near Edna), which will help the northeastern counties feel a bit cooler than yesterday as heat index values are only forecast to reach the mid 90s. The eastern periphery of the upper ridge that has been in control of area wx will erode during the early/middle parts of the week.
Deepening upper level trough axis continues to dig further south across the region with attendant surface front pushing south of I-10 in Duval County through western part of Alachua County. A low pressure center was had formed over earlier this morning over Baker county and now moved over central Duval County. This frontal feature is expected to push further slowly south this afternoon pushing the swath of precipitation gradually southward as upper trough continues to deepen. A cold front is moving southward across NE FL as a broad area of low pressure that formed over the eastern Gulf of Mexico has pushed into southeast Duval County.
1250 PM EDT Sun Jul 30 2017 Dry with pleasant temperatures today as high pressure builds in from the northwest. A cold front from Quebec will approach the region on Monday and move across the region Monday afternoon and evening.
619 AM CDT Sun Jul 30 2017 Another quiet morning across the region as high pressure centered over the western Great Lakes continues to extend southwest into the lower Missouri Valley.
Maliawco An upper ridge will build back into the area today with dry and sunny weather expected. Lee trof along the front range will be strengthening today with circulation centered in southern Alberta. Should see some increase in the generally south winds, mainly focused over north central Montana closest to the low pressure. Canadian high pressure will push south behind the front on Monday, with winds turning north and cooler air filtering south of the border. A few thunderstorms are possible Monday afternoon, focused in southeast Montana where cooler air from the north will encounter the increased moisture on the edge of the monsoonal plume. High pressure begins to concentrate over the Southwest States. But disturbances over Canada will flatten the ridge over Montana Monday evening.
729 AM EDT Sun Jul 30 2017 Dry weather is expected through Sunday as high pressure remains over the North Country. A weak frontal system will drop south from Quebec and could provide some isolated showers generally over the higher terrain on Monday afternoon.
1045 AM EDT Sun Jul 30 2017 A Canadian high pressure system over the lower Great Lakes will build into central NC through Monday, then linger overhead through mid-week. A brisk nly low level flow will advect a drier cooler air mass into central NC. This will yield high temperatures in the low-mid 80s, a solid 5-7 degrees below normal for this time of year. More importantly dewpoints will be in the low- mid 50s, resulting in comfortable humidity. Ridging will dominate with cP airmass over the area undergoing some slight moderation on Monday with temperatures remaining below normal with continued low humidity. Highs Monday in the lower to mid 80s. Lows Monday night in the lower 60s, with some upper 50s possible in the typical cool spots.
911 AM EDT Sun Jul 30 2017 Dry with pleasant temperatures today as high pressure builds in from the northwest. A cold front from Quebec will approach the region on Monday and move across the region Monday afternoon and evening.
1200 PM CDT Sun Jul 30 2017 Another quiet morning across the region as high pressure centered over the western Great Lakes continues to extend southwest into the lower Missouri Valley.
A mostly dry day is store for the region outside a slight chance of showers and storms near the higher terrain and in extreme southeastern Montana. Temperatures will be in the low to mid 90s across the area this afternoon. Today will be a warmer and drier day. The ridge will be a little stronger which will let temperatures for much of the area climb into the low to mid 90s. For the most part today should be dry, but a few afternoon storms are possible mainly over the higher terrain. Going into Monday a cold front will drop through the area.
1158 AM CDT Sun Jul 30 2017 High pressure in the Mid Missisissippi valley will stay in control over the area through Monday afternoon. Northwest flow aloft will continue over the region with a trough over the northeast US and a ridge covering most of the western part of the country. Northwest flow aloft continues with a trof over the eastern US and a large ridge of high pressure over the weatern US.
High pressure is in control from the desert SW northward along the west coast and into the intermountain west. Based on all of these facts it looks like our forecast of isolated shower/t-storm for the higher terrain, mainly in Idaho, appears to be on track. Isolated afternoon and evening thunderstorms, mainly over the higher terrain along the Nevada border and central Idaho. A strong upper level ridge will move into position just south to southwest of the area through Monday. Overnight lows will remain in the lower to mid 60s in the valleys and mainly 50s in the mountains.
858 AM EDT Sun Jul 30 2017 High pressure will maintain dry and seasonable weather through the start of the work week. High pressure will remain firmly in control through most of this period.
1257 PM EDT Sun Jul 30 2017 High pressure will maintain dry and seasonable weather through the start of the work week. High pressure will maintain dry and seasonable conditions for the rest of the day. High pressure will remain firmly in control through most of this period.
A slow-moving inverted trough and deformation area over central Arizona this morning has allowed light showers and extensive cloud cover to persist overnight.
/Issued 343 AM CDT Sun Jul 30 2017/ Our anomalous late- July cold front has slipped south of the region this morning, although you wouldn't necessarily notice it looking at the surface observations or stepping outside. With cooler air in limited supply behind the front, another warm (and muggy) day is on tap across our Central Texas Counties as temperatures look to warm into the upper 90s (perhaps even nearing the century mark south of Waco).
Cooler and drier air flowing in on north to northeast winds has brought a much more pleasant air mass to eastern Kentucky. Temperatures are currently ranging from the mid 50s in some of the cooler spots to our north, to around 60 degrees for most other locations. Aloft, an amplified pattern is in place, with troughing in the east and ridging in the west. High pressure will continue to control from the north through the short term. Another cool night will be on tap tonight, with lows ranging from the mid 50s in the valleys, to around 60 degrees on the ridgetops. A weak short wave trough will pass through the Ohio Valley on Monday, allowing for a bit more cloud cover; however, dry weather will persist. Highs will be a bit warmer still, with low to mid 80s expected.
419 AM CST Fri Mar 2 2018 Ridging dominating the weather across SETX today. Ridge over Missouri extending down into Central Texas will maintain the north-northeasterly flow this morning becoming more easterly this afternoon as it slides slowly eastward. The intense cyclone off the Northeastern Seaboard will push away to the east with the high in its wake. Upper ridging over the Central U.
Downslope wind gradient while not strong today, will help temperatures in the foothills into the lower 40s this afternoon, but cloud cover and easterly winds in the plains will hold highs in the mid 30s. Saturday will see increasing precipitation chances from southwest as strong jet dynamics arrive with upper low moving into Idaho.
A very dry and cooler airmass will filter in on breezy northerly winds. Highs will mostly be in the lower to mid 70s.
Not many obs to go by for the higher elevations but hi-res models all in agreement at wind gusts in excess of 40mph possible for the higher peaks. Temps much cooler than recently especially when you add the breezy/windy conditions. Cold conditions tonight with below freezing for NE GA and right at the freezing mark North of I20. We have started the freeze program for areas outside of the mountains but with temps just touching freezing, will not go with a watch at this time. A more likely scenario would be for day shift to go straight to warning should 12Z guidance come in a little cooler.
630 AM EST Fri Mar 2 2018 After a few straggler rain showers finally exit the area early this morning, a ridge of high pressure will spread across the region. This ridge will bring cooler and drier air into eastern Kentucky, which will lead to clearing skies. Saturday should be slightly warmer, with highs reaching upper 40s and lower 50s around the area. High pressure will remain firmly in control to bring the weekend to a close allowing for clear skies and mild daytime temperatures and cool nights.
417 AM MST Fri Mar 2 2018 Dry SW flow aloft will be over the region today and tonight as a sfc lee trough strengthens along the front range. With downslope SW low level flow in place aftn highs across the plains will be around 10 degrees warmer than yesterday.
High pressure will dominate the region through the weekend, leading to sunny and dry conditions and a gradual warming trend.
Will include fog late in the forecast period as the low level humidity increases. The old cold front will move back up north as a warm starting late tonight into Sat as 500 mb ridging aloft builds over the TX Gulf Coast, northern Mexico and the Gulf of Mex. Deeper layer moisture levels start increasing as the warm front moves north and will maintain some slgt chc/chc pops. WAA will be on the increase into Sat as the low level S-SE flow returns.
/issued 420 AM EST Fri Mar 2 2018/ SHORT TERM (Today - Saturday) The upper high sits over the northern tip of the Yucatan peninsula with broad ridging extending from the Bahamas westward through eastern Mexico. Farther north, a closed upper low sits over the mid-Atlantic states with associated troughing extending south along the eastern seaboard. The low exits into the western Atlantic by early Saturday morning and the upper high shifts slightly westward. On the surface, a weak cold front is moving through the region. Strong high pressure builds in behind this front, which will help to filter in some cooler and drier air into the weekend.
552 AM CST Fri Mar 2 2018 Clear and cool this morning with temps within a degree or two from the freezing mark throughout Central IL. Light northwesterly winds dominate and are expected to become more northerly today as the ridge axis slips to the east. Even with the cooler air and the high pressure moving through the Midwest, plenty of sunshine will help to keep high temps in the upper 40s/lower 50s, above normals for this time of year.
Upper ridge will remain over the southern plains into the early part of the weekend with high temperatures back into the mid to upper 60s Saturday afternoon in many areas.
NNW wind around 10 KT later this morning will turn NNE as weak cold front moves through. Drier air associated with this front will hold through the weekend with cooler mornings and temperatures closer to average for this time of year.
An upper low over the offshore waters will drift southeast into Oregon Saturday night. Showers rotating around the upper low will lift northward through Western Washington today. The threat of showers will then slowly diminish tonight through the weekend as the upper low moves off to the southeast of the area.
Upper level analysis places low off the Pacific Northwest with ridge over the eastern plains. For tonight, upper low off the Pacific shore pushes onshore and stretches to the northeast. On Saturday, upper low transitions over the Canadian Rockies as a deep trough stretches to the south and pushes eastward.
Clouds and precipitation chances increase across far southeast Oregon Saturday morning and to much of the area during the day Saturday as the low moves inland. While the air mass will be cold enough for snow to the lowest valley floors, accumulation will be limited to sites above 4k feet.
319 AM MST Fri Mar 2 2018 Current surface map places trof of low pressure across eastern Wyoming into eastern Colorado. For today, upper level ridge shifts across the northern Plains, with low level thermal ridge over the forecast area. Warmest temperatures will be in downslope area of northern/eastern Black Hills Upper low moves through western CONUS Saturday, with surface cold front sliding into northeast Wyoming/northwest South Dakota Saturday morning and through rest of the forecast area Saturday night.
645 AM EST Fri Mar 2 2018 Low pressure pressure will move off the New England coast today.
After a few straggler rain showers finally exit the area early this morning, a ridge of high pressure will spread across the region. This ridge will bring cooler and drier air into eastern Kentucky, which will lead to clearing skies. Saturday should be slightly warmer, with highs reaching upper 40s and lower 50s around the area. High pressure will remain firmly in control to bring the weekend to a close allowing for clear skies and mild daytime temperatures and cool nights.

Upper-level ridge to also allow for dry conditions and mostly sunny skies areawide.
621 AM EST Fri Mar 2 2018 Dry weather is expected from today through the weekend as a ridge of high pressure settles across the area.
VFR conditions can be expected through the TAF period as high pressure moves through the region. High pressure slides across the area today.
653 AM EST Fri Mar 2 2018 Aviation High pressure will be situated across the Great Lakes region from today through the weekend.
401 AM PST Fri Mar 2 2018 A low pressure system along the West Coast will move slowly southward today through Saturday.
Sfc ridging anchored over the region this morning will gradually shift E of the area this afternoon and evening. Concurrently, an UA trough will be pushing east-southeast to across the Four-Corners region thus veering near zonal flow aloft to the southwest, as well as deepening sfc lee troughing resulting in a tightened pressure gradient and subsequently, breezy southerly winds that may equate Lake Wind Advisory criteria tomorrow aftn.
However, the tilt of the trough which the upper low is associated with is a little fuzzy. The upper low is progged to take a right turn as or even before it gets to our latitude.
739 AM EDT Mon Apr 24 2017 High pressure will be in control across the area through tonight.
As an upper low lifts northeast into the Carolinas today. high pressure will begin to build in for a drying and warming trend this afternoon.
