Aikyam-Lab/Synoptic-Bench huggingface dataset:
Dry and tranquil weather conditions will persist through at least the weekend, but expect continued above normal temperatures as high pressure generally dominates across the region. High temperatures each day across the lower deserts will remain several degrees above normal with readings between 100 and 106 degrees under sunny to mostly sunny skies. Little change in the weather pattern through the weekend is expected as our region continues to fall inbetween upper level troughing across the northern U. and the sub-tropical ridge positioned to the south.
632 AM CDT Thu May 30 2024 (Today) Clusters of showers/thunderstorms continue this morning well west of the area across the high Plains.
The exiting ridge axis over the Great Lakes region will keep us dry throughout the daylight hours. Southerly advection of moisture on the back end of the ridge coinciding with a low pressure system moving east across southern Canada will bring chances for showers and storms late this afternoon into tonight.
While storm potential chances are low (less than 10%), the warmer temperatures will allow for some afternoon cumulus buildups.
It's a beautiful late spring day with high pressure building overhead. Anticyclonic flow around the high will promote winds with a northerly component across our region, though they will be quite light (<10mph) given a relaxed pressure gradient. Can't rule out some patchy fog in the typical fog-prone areas, but dry air in the low levels should keep it from becoming too widespread. Temperatures will reach the mid-upper 70s across the board, and possibly a few spots in the lower 80s.
638 AM CDT Thu May 30 2024 Dry and cooler conditions are expected today with temperatures in the low to mid 80s.
712 AM EDT Thu May 30 2024 Weak low pressure over southeast New England will move slowly away from the area today, with a weak low pressure trough remaining in its wake through this evening.
311 AM MST Thu May 30 2024 Dry and tranquil weather conditions will persist through at least the weekend, but expect continued above normal temperatures as high pressure generally dominates across the region. High temperatures each day across the lower deserts will remain several degrees above normal with readings between 100 and 106 degrees under sunny to mostly sunny skies. Little change in the weather pattern through the weekend is expected as our region continues to fall inbetween upper level troughing across the northern U. and the sub-tropical ridge positioned to the south.
(Today and tonight) Forecast highs today overall look to be about 3-5 degrees warmer than yesterday for locations away from the coast.
900 AM EDT Thu May 30 2024 High pressure of Canadian origin will bring dry and cool conditions today through Friday.
Model soundings highlight effective mixing with this warmer airmass, and we should be able to mix drier air aloft down the surface. Upper air pattern consists of a 500 mb trough over the northern plains with a ridge over the upper Great Lakes 00z Fri. In the extended, the GFS and ECMWF show a 500 mb trough in the northern Rockies 12z Sun which moves quickly into the upper Great Lakes 12z Mon. More troughing then moves into the northern Rockies 12z Tue which moves into the upper Great Lakes 12z Wed. This trough remains over the area into 12z Thu. Late in the period Friday morning, a weakening cold front may support increasing clouds and some light rain by Friday morning in KIWD. High pressure slowly shifts southeast over the Great Lakes Basin into this weekend.
928 AM EDT Thu May 30 2024 Weak low pressure pushes off the New England coast into this afternoon, with a weak low pressure trough remaining in its wake through this evening.
530 AM EDT Thu May 30 2024 Cold front pushes to the coast tonight. Dry and cooler high pressure will build in for Thursday and Friday with below normal temperatures. Troughing over the east remains in place today with northwest flow persisting. 850mb jet modeled around 30 to 35kts and this will be enough to remain well-mixed overnight, especially over the ridges. Trough amplifies today and shifts east into the Atlantic late tonight. Will have strong Canadian high pressure build in behind the trough bringing clear and calm skies tonight. A broad upper low anchored across eastern Canada will continue to dominate the weather conditions within the RNK CWA throughout the forecast period.

729 AM EDT Thu May 30 2024 Weak low pressure over southeast New England will move slowly away from the area today, with a weak low pressure trough remaining in its wake through this evening.
Afternoon temperatures will range from the lower to mid 80s. At the same time, southerly flow aloft in the low levels will help keep moist and unstable air flowing into the Gulf Coast and Southern Plains, as the sfc boundary continues to shift further south towards the Florida Panhandle. Recent model consensus continue to show two upper-level low pressure systems shifting east out of the Great Plains and towards the Great Lakes Region around this timeframe.
920 AM EDT Thu May 30 2024 Dry high pressure to our north will keep temperatures a bit below normal through the end of the week.
Ridging will then remain in control through Friday, with dry conditions and a warming trend that will peak with well above normal highs Friday afternoon. The thermal trough will return during this time, resulting in strong north to northeast winds in the coast range and a Chetco Effect, which will lead to warmer temperatures around Brookings than elsewhere on the coast.
1021 AM EDT Thu May 30 2024 Weak low pressure pushes off the New England coast into this afternoon, with a weak low pressure trough remaining in its wake through this evening.
For the western two-thirds of the forecast area, a mostly dry afternoon is expected with clearing skies and temperatures warming into the low-80s.
Temperatures are in the mid to upper 70s with dewpoints in the low to mid 50s areawide. AC3 Dry and cooler conditions are expected today with temperatures in the low to mid 80s.
Weak troughing today. will transition to weak ridging Fri. However, did not feel comfortable holding without the advisory and banking on all locales staying above freezing, not to mention a few areas got 1-2 degrees colder than forecast last night.
An upper ridge will develop through the day, bringing a 5-10 degree increase in afternoon highs across the area. Friday's highs will also increase before the ridge moves eastward, allowing for a cooler weekend with little activity expected.
150 PM EDT Thu May 30 2024 Dry high pressure to our north will keep temperatures a bit below normal through the end of the week.
119 PM EDT Thu May 30 2024 High pressure centered over the Great Lakes gradually shifts southeastward into the Ohio Valley tonight.

"Cool" low temperatures continue this morning and Friday morning with lows in the low 60s to upper 60s.
BT Current radar is showing weakening showers associated with a cold front making their way into SE MT this morning, expected to exit the state around sunrise. Conditions today will be cooler and breezy following the front with temperatures in the 60s expected across the region. Additional trailing energy from the low will continue to make its way through MT through Friday night. Highs Friday will be warmer with temperatures in the 60s and low 70s.
157 PM EDT Thu May 30 2024 Weak low pressure pushes off the New England coast into this afternoon, with a weak low pressure trough remaining in its wake through this evening.
For this afternoon, light and variable winds coupled with daytime heating will likely promote the formation of a broken cumulus cloud line over portions of the Lower and Middle Keys. High pressure currently over south- central Canada will emerge off the Mid-Atlantic coast by the end of the work week.
Tomorrow the 850mb temperatures look to be a little warmer, and thus high temps in the afternoon will be slightly warmer than today was.
1146 AM EDT Thu May 30 2024 Dry and cooler high pressure will build in for today and Friday with below normal temperatures. Troughing over the east remains in place today with northwest flow persisting. 850mb jet modeled around 30 to 35kts and this will be enough to remain well-mixed overnight, especially over the ridges. Trough amplifies today and shifts east into the Atlantic late tonight. Will have strong Canadian high pressure build in behind the trough bringing clear and calm skies tonight. A broad upper low anchored across eastern Canada will continue to dominate the weather conditions within the RNK CWA throughout the forecast period.
In general, CAMS indicate that the thunderstorms will likely weaken somewhat as the move into our area and interact with the ridging that is in place, but a few strong storms could be possible over portions of our area (especially interior southeast MS) this afternoon. Temperatures area generally in the low to mid 80s across the region, with some locations probably climbing into the upper 80s later today, especially over the southern half of the area. A broad upper trough moves off the east coast tonight into Friday, with weak upper ridging developing over our area. At the surface, high pressure centered along the Mid-Atlantic states will continue to ridge down into our area, maintaining the mainly east to southeasterly wind flow across the region.
A slight warming trend will occur through Friday as onshore flow decreases beneath weak high pressure aloft. A deeper marine layer depth will bring cooler temperatures over the weekend as onshore flow strengthens. ***UPDATE*** Weaker onshore flow today and a shallower marine layer will promote earlier clearing of the marine layer in the valleys and warmer temperatures there as well. Onshore flow with troughing aloft will strengthen over the weekend and bring a cooling trend and deepening marine layer depth.
While bulk shear will remain on the low side, 500-1000 J/kg MUCAPE and modest mid-level lapse rates may still support a marginally severe storm or two. The highest severe risk will occur across SE OK/ along & W of Hwy 75 in NE OK. (Today) Clusters of showers/thunderstorms continue this morning well west of the area across the high Plains.
Weak upper level ridging in the wake of longwave trough currently oriented along the Eastern Seaboard should stunt tstorm development in the eastern half the CWA as it slides east across the CWA. Will need to monitor for flash flooding with PW's this high.
Tomorrow we start to warm back up as a weak upper level ridge builds northward from the Gulf Coast, with highs reaching the upper 70s on the Plateau and low to mid 80s elsewhere.
(Tonight) Quiet/tranquil wx conditions prevail across the central TN Valley this Thu afternoon, as high pressure at the sfc remains layered over much of the eastern CONUS and an upper ridge axis out of the Plains states moves eastward into the region.
251 PM EDT Thu May 30 2024 Dry high pressure will be in control over the next couple of days then move off the coast this weekend. Mild afternoons with cooler than normal overnight temperatures are expected for a few more days. High pressure will continue to slowly shift across the Great Lakes into New England tonight, while the upper level trough to our north keeps us under west to northwest flow aloft.
On Friday, a stronger signal of an approaching trof will pass over Oklahoma nearing the Natural State.
