Pattern Synopsis/Forecast: All eyes remain directed at maturing long-wave blocking pattern. featuring upper level ridging "folding" east across the northern Great Lakes and southern Canada as upper level low pressure slowly rotates across the Ohio and Tennessee Valleys. Classic deformation along the ridge/trough interface backing back west into the southern Great Lakes. After essentially remaining locked in place today, that southern upper low will begin to drift northeast tonight. Areas north of the big bridge should remain dry under just some increasing thin high clouds as we head through this afternoon. Pattern Synopsis/Forecast: At the start of the period, low pressure located across the Ohio Valley region will begin to exit to the west as high pressure builds across the Midwest and Great Lakes Region.
For now, the closed low over the Ohio Valley region is helping to maintain dry and cooler than normal air over the forecast area. The low will begin lifting out in response a to another closed low crossing the Plains states, and the increasing warm advection will result in slight shower chances prior to daybreak Tuesday over southwest portions of the area.
- Unsettled and cool conditions continue into the mid week before warmer and drier conditions return by late week. A widespread precipitation event will begin today as a slow moving closed low in the Desert Southwest moves eastward towards our region.
144 AM EDT Mon May 5 2025 No changes to the forecast this evening as an upper low continues to sit over KY and southern IN, with vort lobes rotating around it that bring some showers to our area. Main culprit are the low freezing level and good mid-level lapse rates. For Tonight, upper trough will continue to move slowly east across the Kentucky with plenty of low level clouds over the area. Even mid to upper 30s over the higher elevations of the Smoky Mountains. Main forcing is due to increasing QG-forcing wrapping around the upper low.
(Today and tonight) High pressure builds in across the southeast US today leaving us high and dry. Temperatures will be near normal for early May with highs in the low to mid 80s and lows in the upper 50s.
(The rest of this afternoon and tonight) Tranquil weather continues tonight with lows expected to be at least a few degrees warmer compared to this morning.
/22/ Tonight and Tomorrow: High pressure remains in control through tonight into Monday. Afternoon highs Monday will moderate toward more seasonal values, rising into the mid/upper 70s F for most, and around 80 F along the highway 84 corridor. This southerly flow is expected to coincide with an eastward shift in the mid-upper level blocking pattern causing a decent amount of lift which will result in widespread showers and thunderstorms with significant rainfall for Tuesday especially.
1025 PM MST Sun May 4 2025 Updated Aviation An unseasonably cool and wet low pressure system will affect the Desert Southwest into Tuesday with below normal temperatures and above normal rain chances.
POPs on Tuesday are confined to northwest OH as the low continues to slide east.
Once this weather system moves out, warmer and drier conditions are expected to take hold, with well above average temperatures by the weekend. The center of the upper level low will track east into Arizona, resulting in northerly flow aloft over the region. Convective activity will slow down and shift east with the center of the low overnight. This means highs in the low 70s for the Las Vegas Valley and Colorado River Valley.
1134 PM CDT Sun May 4 2025 (This evening through Monday night) Tonight through Tuesday morning, conditions will be dry overall with mild conditions thanks to high pressure dominating the pattern. Highs are forecast to be in the low 80s with lows in the mid 50s to mid 60s.
144 AM MDT Mon May 5 2025 - Rain and Mountain Snow Showers Continue Through Tomorrow - Strong Northerly Winds Later Monday - Warmer Weather Returns Later In the Week More showers and thunderstorms are on tap today and Tuesday. In between, we will see a second closed low develop and drop south across Idaho and be absorbed into the bigger area of low pressure. We COULD see up to 6" on ridgetops around there, and perhaps a slushy inch or two along ID-28 overnight.
1215 AM CDT Mon May 5 2025 High pressure will settle into the region today, as a closed low remains over the Ohio and Tennessee Valleys. Meanwhile, a trough digging along the West Coast will continue to amplify, eventually becoming a closed low over the Four Corners Region. The low to the west will move slowly eastward during the first part of the work week, with a ridge building over the region. Attention then turns to the potential impacts the low to our west will bring as we head into the second half of the work week. The axis of the ridge will shift east of the area, with flow aloft increasing and becoming southwesterly. As the low lifts to the north-northeast, a warm front will lift northward into the northern Gulf.
Cooler in the west with strong northerly winds. - Cooler on Tuesday, with a few lingering showers mainly in the southwest. A few showers are present along a cold frontal boundary in northwestern North Dakota. Behind the frontal boundary, cooler highs in the 60s to low 70s are expected for today in far western ND, along with gusty northerly winds. Highs Tuesday will be cooler with most locations remaining in the 60s with some 70s possible near the ND/SD border.
548 AM EDT Mon May 5 2025 - Areas of light rain to continue into Tuesday - Highs in the low to mid 60s today and Tuesday.
621 AM CDT Mon May 5 2025 Taking a look at the synoptics over the Conus and nearby, a pair of closed upper lows were present at this time, one over the Ohio River Valley and a second over the Desert Southwest.
615 AM EDT Mon May 5 2025 (Today and tonight) High pressure builds in across the southeast US today leaving us high and dry. Temperatures will be near normal for early May with highs in the low to mid 80s and lows in the upper 50s.

614 AM EDT Mon May 5 2025 High pressure building down from the north will crest over the area today.
A upper level ridge will produce dry and warmer conditions across Western Washington through Tuesday. A weak frontal system will arrive midweek with cooler temperatures and a chance of showers. Somewhat warmer and generally dry conditions return late week before another front approaches the region over the weekend.
HRRR continues to go warmer and drier. A cold front is located from central Manitoba southwest to west of Dauphin to the Estevan SK area then to Watford City and into southeast Montana. For today, the cold front will slide southeast with the wind shift by 00z near Winnipeg to Langdon to north of Bismarck then into western South Dakota. Ahead of this front it will remain unseasonably warm with highs in the low 80s. NBM remains a bit cooler than this more along the 80-83 range from Fargo northward to Pembina with warmest in Pembina. Cooler for most areas Tuesday, esp northeast ND. High pressure slides east thru Manitoba into NW Ontario Tues night-Wed keeping area in northeast sfc flow but cooler temps and higher dew pts and fire weather concerns are diminished.
905 AM EDT Mon May 5 2025 High pressure building down from the north will crest over the area today.
A strong Pacific weather system will bring cooler temperatures over the coming days with periodic chances for scattered showers. Strong winds evident on the latest water vapor imagery along the SW periphery of the upper-low will serve to elongate the upper low as it moves across Arizona today, shifting it from a positive-tilt to a more neutral-tilt along eastern Arizona this afternoon. As this happens, the mid and upper trough axis will swing across Southeast Arizona late this morning into early this afternoon. Although the mean trough maintains itself across the Great Basin and southern Rockies for the next few days, the upper-low center along the AZ/NM border this afternoon moves into northern New Mexico overnight tonight.
Taking a look at the synoptics over the Conus and nearby, a pair of closed upper lows were present at this time, one over the Ohio River Valley and a second over the Desert Southwest.
428 AM CDT Mon May 5 2025 (Today) Water vapor shows an upper level low over the lower TN valley this morning. A few sprinkles may occur early this morning, but a dry day is anticipated as the low pivots northeast through the day. Depending on how fast this occurs, afternoon highs may vary from the lower to middle 60s in southern middle TN to the upper 60s to around 70 in north AL.
Stacked low pressure system remains nearly stationary over Ohio today. The low will only slowly lift northward tonight keeping us mainly socked in with low cloud today although there are indications CIGS will improve to around 1500ft this afternoon. Winds will be out of the NE/E today but will go variable tonight with the low overhead. The center of a vertically stacked closed low pressure system will remain fairly stationary over the Ohio River today.

Daytime high temperatures will peak in the mid to upper 80s over northeast Florida with southeast Georgia in the low to mid 80s. Overnight, rain and isolated storms shift to the offshore waters with lows dipping into the upper 50s to mid 60s, with the warmer temperatures closer to the coast.
Lower 50s to mid 60s in northern lower, coolest on Lk Huron and warmer near MBL. Pattern Synopsis/Forecast: All eyes remain directed at maturing long-wave blocking pattern. featuring upper level ridging "folding" east across the northern Great Lakes and southern Canada as upper level low pressure slowly rotates across the Ohio and Tennessee Valleys. Classic deformation along the ridge/trough interface backing back west into the southern Great Lakes. After essentially remaining locked in place today, that southern upper low will begin to drift northeast tonight. Areas north of the big bridge should remain dry under just some increasing thin high clouds as we head through this afternoon. Pattern Synopsis/Forecast: At the start of the period, low pressure located across the Ohio Valley region will begin to exit to the west as high pressure builds across the Midwest and Great Lakes Region.
The omega blocking pattern will begin to break down on Tuesday before transitioning to a rex block for the middle of the week.
(This evening through Tuesday) High pressure over the area will keep dry and cool conditions through today and tonight. A low pressure over the Ohio Valley will produce plenty of clouds, with wrap around clouds across areas of northern Alabama today. Otherwise, tonight, the high pressure slowly meanders east with low and mid level flow prevailing from the south. Highs tomorrow will be several degrees warmer, closer to normal, thanks to that low and mid level flow.
A cold front will then move through our CWA from the west bringing another round of convection.
101 PM EDT Mon May 5 2025 A cold front will stall just offshore as high pressure begins to build into the region.
Expect the upper level low across southeastern Arizona this afternoon to cross New Mexico and emerge into the southern Plains over the next 24 to 36 hours.
247 PM EDT Mon May 5 2025 * Upper level low continues to slowly move through the region, with additional isolated to scattered light showers possible until this evening. * Drier weather looks likely for Tuesday with another chance of rain around mid-week with a potential cold front moving through. Temperatures have reached the mid to upper 50s so far today, with both the GOES satellite imagery and radar showing the evidence of the upper low still over the area. For tonight, the upper low will begin to slowly drift northeastward over Ohio, with an upper level omega block patten set up across the country. With the upper low pulling away and to the northeast tonight, drier conditions are expected as we get into the overnight hours.
- Cooler on Tuesday, with a few lingering showers mainly in the southwest. UPDATE A few showers are present along a cold frontal boundary in northwestern North Dakota. Behind the frontal boundary, cooler highs in the 60s to low 70s are expected for today in far western ND, along with gusty northerly winds. Highs Tuesday will be cooler with most locations remaining in the 60s with some 70s possible near the ND/SD border.
(This afternoon through Tuesday night) The upper-level trough, visible on water vapor satellite imagery, continues to make its way through Arizona towards New Mexico this afternoon. Lift associated with the approaching trough, along with continued difluence aloft and convergence along the dryline, will encourage the development of a few isolated supercells this afternoon. These storms will quickly coalesce into a line, and would continue to pose a threat of all modes of severe weather (especially given the increasing low-level shear associated with the low-level jet - this would help increase the tornado threat somewhat). At this time, the highest storm chances look to be for the Permian Basin and Trans-Pecos regions (60-90% chance).
1213 PM MDT Mon May 5 2025 - Rain and Mountain Snow Showers Continue Through Tomorrow - Strong Northerly Winds Later Monday - Warmer Weather Returns Later In the Week More showers and thunderstorms are on tap today and Tuesday. In between, we will see a second closed low develop and drop south across Idaho and be absorbed into the bigger area of low pressure. We COULD see up to 6" on ridgetops around there, and perhaps a slushy inch or two along ID-28 overnight.
141 PM EDT Mon May 5 2025 - Areas of light rain to continue into Tuesday - Highs in the low to mid 60s today and Tuesday.
1231 PM EDT Mon May 5 2025 High pressure building down from the north will crest over the area today.
Coverage of showers and thunderstorms increases late this afternoon as energy rotates around the east side of this low. Rain showers will pivot around this low as it begins to depart the area - withe the best coverage across the north and northeast counties. Rain chances end from southwest to northeast as the low continues to pull away from the region. Temperatures fall to lows from the upper 40s to the lower 50s.
Once this weather system moves out, warmer and drier conditions are expected to take hold, with well above average temperatures by the weekend.
