318 AM EDT Fri May 31 2024 High pressure will make for warm and mostly dry days in the short term with breezy northwesterly winds. A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon.
Pleasant conditions will occur today with daytime highs returning to seasonable levels (valleys in the upper 60s to 70s) as a weak ridge passes through the Northern Rockies.
408 AM EDT Fri May 31 2024 High pressure of Canadian origin will bring dry and cool conditions today. High temperatures to range from the mid/upper 70s west to the lower 80s east.
Not surprisingly, mild temperatures will persist given the extent of cloud cover and convection over the next few days with highs generally in the lower to mid 80s and overnight lows in the mid 60s to near 70 degrees.
Today and Saturday Quiet weather expected to round out the work week as weak upper level ridging builds over the region today. Under high pressure, temps will rise quickly this morning and nearing seasonal norms for daytime highs which means upper 60s and lower 70s in the valley locations, 60s in the mountains. Not expecting any frost concerns overnight Friday into Saturday as overnight lows will generally be in the low to mid 40s.
- One more day today of seasonally cooler temperatures and dew points will subsequently transition to a more summer-like air mass thereafter. This occurs in advance of our next storm system, a low pressure wave that opens itself up as it tracks into/across our region Saturday.
309 AM EDT Fri May 31 2024 High pressure will make for warm and mostly dry days in the short term with breezy northwesterly winds. A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon.
Relatively dense mid-level and upper-level clouds are expected (downstream of clusters of convection over the ArkLaMiss), so have used slightly lower (cooler) temperature guidance. The exception looks to be portions of northeast Georgia, mainly the higher terrain.
Snow levels are around 7kft so some light accumulation is expected over the high elevations (less than 1").
Warmer than normal temperatures and dry weather will continue into the weekend. Winds will pick up over the weekend as a trough moves through the area. The first full week of Meteorological Summer will be characterized by hotter than normal temperatures due to a ridge of high pressure over the Western US.
(Today through Saturday) Currently we have a ridge in place across the area. This ridge is holding firm as an approaching MCS is beginning to weaken in intensity. At this time it does not appear that the MCS will be able to penetrate the ridge, but an outflow from the northern edge of the associated MCV will slide across the western edge of the state through the morning and could provide a brief shower or two. On Saturday, this boundary, in association with an approaching trough that will displace the ridge to the east, will result in a fairly good coverage of showers and storms.
Highs today will be warmer as an upper level ridge moves overhead, but humidity levels will still be nicer than usual for this time of year.
Rain chances will remain high through Saturday as a cold front moves across the area.
High pressure will keep the weather dry for the next several days.
228 AM EDT Fri May 31 2024 High pressure of Canadian origin will bring dry and cool conditions through Friday. An associated weak cold front will cross the area Saturday night, although there are some timing differences depending on how strong a wave might develop along this front.
Actual rain chances are probably around 10 percent in the west and southwest associated with some lift from an upper low. High amplitude ridging will migrate further east overnight, with the narrow ridge axis extending roughly over much of the Mississippi River Valley Region. The result will be increasing clouds from the southwest that will expand north and east through the day accompanied by growing chances for some shower and thunderstorm activity far west initially then expanding eastward behind the ridging as it moves further east of the area. High temperatures will range from the low 80s in the higher elevations far east to near 90 southwest and far south.
1256 AM EDT Fri May 31 2024 A weak trough will pass through overnight. High pressure will then build toward the area tonight into Friday, and remain in control through Saturday.
High pressure remains the primary feature across the region and will keep clear skies and light winds across the forecast area. Lows will bottom out primarily in the lower and mid 50s by daybreak Friday although a few spots may sneak into the upper 40s over eastern counties. Mostly clear skies should continue through the period, but some diurnal cu will develop this afternoon once convective temperatures in the low-mid 70s are reached. Expect another cool night in the low 50s under optimal radiational cooling conditions.
Canadian high pressure will otherwise extend across the region through early Saturday, then drift off the coast of the Carolinas by Saturday night. 5", which is in the lowest 0-1 percentile of the climatological data set. The weather headlines will be the seasonably cool/below normal temperatures and ultra comfortable humidity as Canadian high pressure settles over much of the Eastern Seaboard. Warmer, but still slightly below normal for the 1st day of meteorological summer. Upper ridge axis moves offshore Saturday night.
Highs Friday should range from the upper 80s beachside to the low 90s over the interior and Greater Orlando area. High pressure ridge builds into the western Atlc and considerable dry air is forecast to move in from the east. ) Boating conditions will deteriorate slightly into this weekend, as high pressure builds south down the eastern seaboard then shifts off the Carolina coast.
233 AM CDT Fri May 31 2024 - Weak instability associated with a slow-moving low pressure system will bring some showers and thunderstorms (80-90% chance) through central Illinois overnight tonight into late Saturday.
Afternoon high temperatures for the remainder of the week will stay in the upper 80s to low 90s, with the highest temperatures expected in the western parts of the region.
Will continue to see the increase in clouds as an upper trough exits off the northern Atlantic coast and broad upper ridging pushes warm and moist flow into the area. A slow moving warm front will lift north of the area today, and rain chances will increase over northwest AL later this afternoon.
High pressure slipping from the Great Lakes to the Appalachians will continue our dry, pleasant weather tonight and tomorrow. A 50kt low level jet will help to bring slightly above normal precipitable waters into the area as surface dew points rise into the lower and middle 60s.
With light winds beneath clearing skies, much of the region is in for a cool morning, with areas above 1500 ft elevation starting the day in the upper 30s, while lower elevation locales begin in the low to mid 40s. Steep low-level lapse rates up to 800-850 hPa developing by this afternoon will allow for some stronger west to northwest winds to mix down to the surface, potentially gusting as high as 20-25 mph along the Mohawk Valley, across the Capital District, and in the higher terrain of the eastern Catskills and Berkshires. Pleasant weather continued into the weekend as upper ridging approaches from the west on Saturday and passes overhead on Saturday night.
136 AM EDT Fri May 31 2024 Canadian high pressure will build southeast into Pennsylvania Friday and Saturday.
Warmer today, with temperatures closer to normal. Discussion: Another quiet day across the area with high pressure firmly in control. The ridge axis shifts east and will be centered across the area today. This means warmer temps and light winds.
This is all in association with a trough of low pressure aloft that will be sliding over the region today. In the wake of the morning MCS down south, the data focuses storm coverage over western AR and neighboring far eastern OK, on the east side of the low pressure aloft. PoPs and thunder probs will decrease tonight as the low pressure aloft slides east and we lose daytime heating.
146 AM EDT Fri May 31 2024 A weak trough shifts south overnight. High pressure will then build toward the area Friday, and remain in control through Saturday.
248 AM MDT Fri May 31 2024 - Cooler and showery weather for much of the area today. - Warmer over the weekend with daily chances for showers and thunderstorms. Current surface analysis shows cold front just south and east of the forecast area, with weak high pressure over WY. Upper level analysis shows low over south central Canada, with trough extending southward into the northern and central Plains. Highs will stay on the cooler side today, 60s and lower 70s, with some 50s across the higher Black Hills. Another cooler night expected with lows mostly in the 40s early Saturday. Warm advection aloft starts to take place later tonight and especially on Saturday as trough shifts east-northeast of the region.
357 AM EDT Fri May 31 2024 High pressure will continue to influence the Mid-Atlantic region through Saturday before moving offshore.
132 AM EDT Fri May 31 2024 Dry high pressure to our north will keep temperatures slightly below normal through the end of the week. Once the high moves off to our east late Saturday, we should see a gradual warm up with a return of mainly afternoon and evening showers and thunderstorms, typical of early summer. The high will tighten the gradient, amplifying winds slightly in the Piedmont late tonight and turning them toward the NE. Max temps overall will be a few below normal--perhaps trending a degree or two cooler in our eastern zones, and a degree or two warmer in our southwest compared to today, reflecting the thickness pattern.
No weather concerns for the next 36 to 48 hours as high pressure dominates, with plenty of sunshine and slowly moderating temperatures.
By late in the day, at least some scattered convection is expected to once again develop across the High plains to our west.

A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon.
Dew points are in the lower to mid 70s. From synopsis, high pressure over the Ohio Valley will dive southeastward, emerging off the Mid- Atlantic coast over the weekend.
622 AM CDT Fri May 31 2024 (Today through Saturday) Currently we have a ridge in place across the area. This ridge is holding firm as an approaching MCS is beginning to weaken in intensity. At this time it does not appear that the MCS will be able to penetrate the ridge, but an outflow from the northern edge of the associated MCV will slide across the western edge of the state through the morning and could provide a brief shower or two. On Saturday, this boundary, in association with an approaching trough that will displace the ridge to the east, will result in a fairly good coverage of showers and storms.
High clouds are beginning to advect across Lower Michigan from the west as the next low pressure system develops. Today will be dry, however and a bit warmer than yesterday.

718 AM EDT Fri May 31 2024 High pressure will make for warm and mostly dry days in the short term with breezy northwesterly winds. A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon.
Rain chances will be greatest tonight and Saturday, aided by an upper level low pressure system lifting out of the southern plains.
However, water vapor channel imagery highlights several southward-moving midlevel waves which still have the potential to ignite additional elevated convection as they intercept a modest low level theta-e ridge over the South Plains and Rolling Plains.
611 AM EDT Fri May 31 2024 High pressure will make for warm and mostly dry days in the short term with breezy northwesterly winds. A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon.

Highs will stay on the cooler side today, 60s and lower 70s, with some 50s across the higher Black Hills. Another cooler night expected with lows mostly in the 40s early Saturday. Warm advection aloft starts to take place later tonight and especially on Saturday as trough shifts east-northeast of the region.
MCS likely to form early Friday morning across much of northern Texas with a cold front moving south along the leading gust front of this system. Cooler temperatures tomorrow behind frontal passage in the morning. Cooler surface air and a strong capping inversion at 750 mb will greatly hinder afternoon storm chances.
637 AM EDT Fri May 31 2024 A large area of Canadian high pressure will drift southeast from the Great Lakes/Ohio Valley region and become centered over Pennsylvania tonight into Saturday.
332 PM EDT Fri May 31 2024 High pressure of Canadian origin will bring dry and cool conditions through this evening. The chance for rain persists Saturday night with the upper level trough axis pivoting through. Surface flow will be southerly to start the night before shifting to the west later on the western side of the trough axis.
Weak ridging over the region today, tonight, and Sat AM will continue to support dry conditions, mostly sunny/clear skies, fairly modest winds, and high temps in the mid-60s to low 70s. Low temps Sat AM should average 3-5 degrees warmer than what we saw this morning, thus frost is not expected to be an issue (and hopefully won't be an issue again this spring).
Tonight, these clouds will shift further east, along with upper-level ridging. Saturday During the day on Saturday, high pressure will recede to the northeast with fairly strong (35 to 40 kts) 850mb flow, especially in western portions of the area.
Strengthening onshore flow in the low-levels with NE-E winds increasing to 15 to 20 mph into this afternoon with frequent gusts to 20 to 25 mph and occasional gusts to 30 mph within play as the pressure gradient tightens between lower pressures to the south and high pressure building out of the Ohio Valley and towards the mid Atlc coast and southeast U.
This also led to a very slight reduction in the high temperature forecast. Warmer today, with temperatures closer to normal. Discussion: Another quiet day across the area with high pressure firmly in control. The ridge axis shifts east and will be centered across the area today. This means warmer temps and light winds.
302 PM EDT Fri May 31 2024 Unseasonably mild temperatures are expected through Saturday as dry high pressure moves from the Great Lakes to the eastern Carolinas.
Low level moisture has also begun increasing with dewpoints up into the low 60s across our southwest, and this may be enough for a few showers to pop up by late afternoon into the evening in that area. However, bulk of rain will arrive overnight and spread eastward across the midstate through Saturday morning as an upper level trough shifts eastward from the southern Plains.
222 PM MDT Fri May 31 2024 - Cooler and showery weather for much of the area today. - Warmer over the weekend with daily chances for showers and thunderstorms. Current surface analysis shows cold front just south and east of the forecast area, with weak high pressure over WY. Upper level analysis shows low over south central Canada, with trough extending southward into the northern and central Plains. Highs will stay on the cooler side today, 60s and lower 70s, with some 50s across the higher Black Hills. Another cooler night expected with lows mostly in the 40s early Saturday. Warm advection aloft starts to take place later tonight and especially on Saturday as trough shifts east-northeast of the region.
1239 PM CDT Fri May 31 2024 (Today through Saturday) Currently we have a ridge in place across the area. This ridge is holding firm as an approaching MCS is beginning to weaken in intensity. At this time it does not appear that the MCS will be able to penetrate the ridge, but an outflow from the northern edge of the associated MCV will slide across the western edge of the state through the morning and could provide a brief shower or two. On Saturday, this boundary, in association with an approaching trough that will displace the ridge to the east, will result in a fairly good coverage of showers and storms.
Thunderstorms have already begun to fire in the high terrain of New Mexico and are expected to propagate eastward through the afternoon and evening. Tomorrow's weather setup is similar to today, with moisture and instability extending to the high terrain of New Mexico. The 500mb ridge is expected to slide slightly eastward and should continue to prevent convection over the forecast area during the afternoon.
1115 AM EDT Fri May 31 2024 High pressure will make for warm and mostly dry days in the short term with breezy northwesterly winds. A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon.
Another pleasant and seasonable weather day is occurring across the state this afternoon as we remain largely under high pressure.
A weak disturbance on Saturday will bring the potential for a few thunderstorms, mainly along and south of the Highway 12 corridor.
The main threat still appears to be instances of flash flooding as a slow-moving upper low pushes into the region from the west. Rain chances will be greatest tonight and Saturday, aided by an upper level low pressure system lifting out of the southern plains.
146 PM EDT Fri May 31 2024 Unseasonably mild temperatures are expected through Saturday as dry high pressure moves from the Great Lakes to the eastern Carolinas.
246 PM EDT Fri May 31 2024 Dry high pressure centered over the region will keep temperatures slightly below normal, with dry weather persisting through Saturday.
1258 PM EDT Fri May 31 2024 High pressure will build toward the area through Friday, and remain in control through Saturday as it moves off the Mid Atlantic coast.

249 PM EDT Fri May 31 2024 High pressure and dry conditions will continue through Saturday.
Overnight, previous convection across the High Plains is expected to propagate southeastward towards western Oklahoma (after 2 AM).
Early this afternoon, upper air data and satellite was depicting a high amplitude ridge from Hudson Bay to the Tennessee Valley. Meanwhile, at the surface, broad high pressure was found over the eastern Great Lakes and upper Ohio Valley and broad low pressure was over the Southwest. Meanwhile, the thick cloud cover and rain will likely limit temperatures to the lower 70s Saturday afternoon.
(Tonight) A weak area of low pressure was moving to the NE over the eastern Red River Valley of OK/TX, and bringing an increase in clouds to the area. Despite the thickening clouds, area temperatures have warmed into the low/mid 80s, with SE winds of 5-15 mph. Lows tonight should cool into the low/mid 60s.
122 PM MDT Fri May 31 2024 - Warmer over the weekend with daily chances for showers and thunderstorms.

Even though we will be drier a strong easterly wind will help to keep temperatures slightly cool with inland areas actually a few degrees cooler then areas along the coast.
137 PM EDT Fri May 31 2024 High pressure of Canadian origin will bring dry and cool conditions through this evening. The chance for rain persists Saturday night with the upper level trough axis pivoting through. Surface flow will be southerly to start the night before shifting to the west later on the western side of the trough axis.
356 PM EDT Fri May 31 2024 High pressure of Canadian origin will bring dry and cool conditions through this evening. The chance for rain persists Saturday night with the upper level trough axis pivoting through. Surface flow will be southerly to start the night before shifting to the west later on the western side of the trough axis.
Temperatures will remain cooler. Widespread thunderstorm activity will return on Saturday as an upper level trough passing through the region helps enhance thunderstorm development along the dryline straddling region.
