Aikyam-Lab/Synoptic-Bench huggingface dataset:
Showers and scattered thunderstorms will be moving across eastern Kentucky this morning, as a cold front pushes through the region. Widespread clouds, precip, and the passage of the front, will lead to much cooler temperatures today around the area, with highs expected to be a couple of degrees below normal. The timing of frontal passage later today will mean that temperatures will likely begin to drop off before dark, or a non-diurnal pattern, as cooler air filters into the region behind the departing front.
856 AM EDT Mon May 16 2022 Showers and a few thunderstorms are expected today with a crossing cold front. Dry weather returns tonight and Tuesday under high pressure. The minor severe threat will cease as the leading edge of convection completes passage across the ridges. Sct showers/psbl tstms will remain possible this afternoon given very cold air aloft with the aforementioned upr trough.
607 AM EDT Mon May 16 2022 A cold front will move southeast across the area later today, followed by high pressure tonight into Tuesday.

By this afternoon, the center of an upper trough will move across the forecast area. The cool air associated with the trough in combination with diurnal heating will bring steep lapse rates during the afternoon. Lead mid level trough axis featured within a broadening area of height falls anchored overhead early this morning. A slightly cooler resident thermal profile relative to the weekend countered by a respectable degree of insolation under thinning cloud and deeper mixing. Potential for a slightly greater recovery and will nudge projected highs up into the lower to mid 70s most locations. This process will draw the attendant cold front through Southeast Michigan, offering a reinforcing shot of cooler air heading into Tuesday.
(Issued 353 AM CDT Mon May 16 2022) Today and tonight: An upper trough swinging across Lake Superior, steep lapse rates in a dry atmosphere, and deep mixing will bring gusty west- northwest winds to southern WI today. Temperatures will be similar to yesterday with highs in the lower to mid 70s. A wind shift at the lakeshore is expected this evening as a cold front makes its way down the lake.
GOES-16 visibile satellite imagery highlights partly to mostly cloudy skies across the island chain, with temperatures in the lower 80s. Water vapor imagery shows a dominant ridge building eastward in the vicinity of the Rockies. This will slowly force the trough to eject northeastward into the North Atlantic. As the trough continues to pivot northeastward, drier air is expected to push into the CWA, which should continue to lower rain chances for the balance of today and tonight. The main conundrum is if a cloud line can form along portions of the Lower and Middle Keys this afternoon with daytime solar insolation. From synopsis, light to gentle, mainly southerly breezes will prevail early this week, as high pressure remains over the eastern Atlantic.
After max temps today in the upper 70s to lower 80s, highs Tuesday will creep back up into the lower half of the 80s.
Monday-Tuesday: A trough pattern will persist early this week. A look at nighttime satellite imagery shows that low stratus clouds have been able to push farther inland this morning thanks to the trough deepening the marine layer a bit. Overnight lows will be in the low 40s to low 50s.
Dry conditions continue into the overnight hours with mostly clear skies and dry air combining to create ideal radiational cooling conditions with lows dropping into the low to mid 50s.
640 AM EDT Mon May 16 2022 Cooler and drier conditions take over for today and Tuesday with increased wind gusts expected today.
The high pressure that has brought us record temperatures over the weekend will weaken and shift eastward this week as the broader synoptic flow slowly buckles. A weakness in the flow combined with the higher latitude transition season storm track dipping a little may enhance the surface gradient a bit for some breezy to locally windy conditions late in the week. Minimum relative humidity values will be in the low single digits to lower teens with poor overnight recoveries.
Showers and storms will form along the inland moving east coast sea breeze, which should be slightly slower to develop due to a weak offshore wind flow in the lower levels. An approaching mid-level trough, combined with cold temps and drier air aloft, may again support isolated stronger storms today, producing frequent lighting, hail and strong wind gusts. (Previous Discussion) Atlc ridge axis will retreat south and east resulting in a SW wind flow turning E/SE this afternoon and evening increasing near 15 knots.
Synoptic pattern remains generally on track with the upper trough over the central Gulf giving way to a building ridge that looks to strengthen over the Central CONUS over the next several days. With the building ridge and continued WAA/moisture advection persisting, hot and humid conditions will prevail with a gradual warming trend over the next several days. Given this, have opted to continue to side towards the lower end of NBM distribution with highs today inching closer towards the mid 90s and increasing a further 1-2 degrees tomorrow afternoon. Expect lows in the lower 70s inland and in the upper 70s along the coast.
Generally fair and warmer conditions expected Tuesday through late week. Otherwise, lows should end up in the mid 60s with dewpoints remaining in the low to mid 60s as well. The synoptic setup for the remainder of today will be a trough moving from the Ohio Valley into New England with associated surface cold front expected to push through the eastern seaboard this afternoon and evening. Even with the front east of us tonight, upper troughing remains in place into Tuesday morning as do some mid-level clouds. Weak upper trough to shift to our east, with a dry NW flow aloft for our region. Some drier and slightly cooler air expected to enter the region Tuesday behind the front, with some downslope flow developing at h85.
549 AM CDT Mon May 16 2022 Dry and breezy conditions are forecast today, with somewhat warmer weather for Tuesday.
520 AM EDT Mon May 16 2022 Showers and a few thunderstorms are expected today with a crossing cold front. Dry weather returns tonight and Tuesday under high pressure. Storms should intensify by late morning/early afternoon as diurnal instability builds, though the highest chances of severe storms should be just to the east of the PBZ forecast area where a later FROPA is progged.
Upper ridging aloft could provide some lift as short wave departs and ridge once again pushes overhead. A 1017mb high pressure will be over SW MO by daybreak and allow for some cooler temps than we have seen lately. Then expect to get to back to summer with the ridge eventually, but more light NW flow overnight may have a little more rainfall in the offing before the drought is reinforced.

High pressure will remain over the area keeping rain-free conditions, winds around 10 knots and seas 2 feet or less over the eastern gulf waters for most of the week.
Slightly cooler today, however temperatures remain above normal with highs generally in the 80s.
613 AM CDT Mon May 16 2022 (Today) A cold front was seen pushing through western TN early this morning followed by drier and slightly cooler air. A benign weather day in store for the Tennessee Valley, as high pressure pushes southeast toward the area. Northerly flow will keep temperatures on the cooler side today, topping out in the low to mid 80s this afternoon.
512 AM MDT Mon May 16 2022 Current surface analysis shows high pressure centered over the central Plains, with a cold front hanging to the north of the region, from northern ND to northern MN. Upper level analysis shows ridge over the Rockies, slowly moving toward the Plains. Today will be warm, with highs in the mid 70s to mid 80s, cooler across the higher Black Hills. Ahead of the front, south-southeast winds will bring increasing moisture into the area, along with the warmer air. Tuesday will be a little cooler behind the front, but still near to slightly above average levels.
After patchy fog this morning, temperatures will warm to many degrees below normal in north-central Idaho, and a few degrees warmer than normal in western Montana.
/NEW/ /Through Tuesday/ An upper ridge will restrengthen over the area today in the wake of last night's active weather. A disturbance rounding the top of the ridge will generate more convection tonight, but his activity should stay north of the Red River. The front will lift back to the north tonight, bringing hotter weather to the region on Tuesday with highs ranging from the lower 90s in the northeast to over 100 in the west. /Issued 256 AM CDT Mon May 16 2022/ /Tuesday night and Beyond/ A dominant ridge will continue to provide hot weather to the region for a good part of this week.
518 AM PDT Mon May 16 2022 A weak trough of low pressure will bring a little stronger onshore flow with cooling into Tuesday with westerly wind gusts to 45 mph in the mountains and deserts for this afternoon and evening.
A ridge of high pressure aloft remains centered over the Rocky Mountains with troughing to the east leaving northwest flow over our forecast area heading into today. Short-term and high-res model guidance continue to struggle with resolving mesoscale details in the wake of the various complexes, but with northwest flow, outflow boundaries in the region, and a moist and unstable airmass south of the approaching cold front, it is reasonable to expect that another round of showers and thunderstorms will develop across parts of our forecast area again today. This air mass should creep eastward into southern portions of our forecast area through the morning as the system to our west edges closer and with low-level westerly flow in advance of the cold front.
/issued 305 AM CDT Mon May 16 2022/ Slightly cooler today with upslope easterly flow.
532 AM CDT Mon May 16 2022 (Today and tonight) With the passage of last night's cold front, cooler air has begun filtering into the region. Afternoon highs will range from the lower 80s in north central and central Oklahoma to the lower 90s in western north Texas (a good 5-10 degrees cooler than yesterday for most locations). Most models (both synoptic and CAMs) have storms developing off the high plains by late afternoon / early evening, then making their way eastward through the evening and into the night. The possibility of upscale growth combined with modest instability (with the higher instabilities farther south) could present a brief conditional severe risk.
1131 AM EDT Mon May 16 2022 Thunderstorms, some severe, will sweep east across the Commonwealth late this morning through the mid afternoon hours, along and just in advance of a relatively strong cold front.
245 PM EDT Mon May 16 2022 Thunderstorms, some severe, will sweep east across the Commonwealth late this morning through the mid afternoon hours, along and just in advance of a relatively strong cold front.
The lower CIGS related to the overnight MC (moving down from NTX) will continue to mix out this afternoon as the upper ridge begins to build into the state. Synoptic pattern remains generally on track with the upper trough over the central Gulf giving way to a building ridge that looks to strengthen over the Central CONUS over the next several days. With the building ridge and continued WAA/moisture advection persisting, hot and humid conditions will prevail with a gradual warming trend over the next several days. Given this, have opted to continue to side towards the lower end of NBM distribution with highs today inching closer towards the mid 90s and increasing a further 1-2 degrees tomorrow afternoon. Expect lows in the lower 70s inland and in the upper 70s along the coast.
1224 PM EDT Mon May 16 2022 Dry weather returns tonight and Tuesday under high pressure, but rain is back in the forecast for mid week. The minor severe threat will cease as the leading edge of convection completes passage across the ridges. Sct showers/psbl tstms will remain possible this afternoon given very cold air aloft with the aforementioned upr trough. That high wl maintain dry and cool conditions on Tuesday as the effects of east coast upper troughing continue.
1131 AM MDT Mon May 16 2022 Current surface analysis shows high pressure centered over the central Plains, with a cold front hanging to the north of the region, from northern ND to northern MN. Upper level analysis shows ridge over the Rockies, slowly moving toward the Plains. Today will be warm, with highs in the mid 70s to mid 80s, cooler across the higher Black Hills. Ahead of the front, south-southeast winds will bring increasing moisture into the area, along with the warmer air. Tuesday will be a little cooler behind the front, but still near to slightly above average levels.
Activity should end after midnight and expect dry and slightly cooler conditions Tuesday but still highs will be in the 60s for the most part in the mountains and in the 70s low elevations.
(Tonight) High pressure reigns supreme across eastern Oklahoma and western Arkansas today with the front that brought the severe weather to the region yesterday evening stalled across north Texas. Scattered showers and storms will once again be possible Tuesday night across portions of northeast Oklahoma and northwest Arkansas as the front that is currently stalled out across north Texas returns to the north across the area as a warm front.
315 PM EDT Mon May 16 2022 As the trough across the northeast becomes negatively tilted this afternoon and evening, the surface level low strengthens over New England. The weak attendant cold front that has been draped across Tennessee/Alabama this morning has started to work its way through the northwestern corner of Georgia this afternoon. Behind the cold front that should make its way out of the forecast area by the early morning hours tomorrow, more seasonable temperatures will return and much drier conditions will prevail under mostly sunny skies. KAL A slightly stronger-than-normal (for this time of year) upper ridge will be in control across the Gulf coast / Southeast region for the first part of this period.
