956 PM EST Fri Mar 7 2025 Low pressure keep snow across the region before tapering off from west to east overnight. KEY MESSAGES: - Snow continues before tapering off overnight - Upslope flow provides some minor accumulation in the ridges ------------------------------------------------------------------- The latest meso analysis shows the frontogenesis at 850mb weakening. Ascent will wane from NW-SE after midnight, though some upslope component will keep snow in the ridges. Additional accumulation should be an inch or less for most areas, with one to three in the ridges.
- Warmer temperatures today, then much cooler on Saturday.
High pressure will hold over the area tonight with mostly clear skies and light winds. High pressure will move eastward near the Bahamas this afternoon starting a warm up trend that will continue into the weekend.
Latest satellite imagery clearly shows two main low-pressure systems spinning across the central and southwestern CONUS. The mid-upper level low over the Four Corners is the one who will bring more dynamic/lifting into the region on Saturday as it shifts east-northeast across the southern Plains. Low to mid-level warm air advection ahead of the low system will lead to increasing clouds tonight, along with light drizzle/showers, particularly along the coast. Cooler and breezy to windy northwest winds are expected behind the front with higher gusts along the coast.
(This evening through Saturday night) Upper level analysis currently shows zonal to very mild ridging across much of the US east of the Rockies and a closed low near Arizona. Going into Saturday, a trough dipping out of Canada across the northeastern US will suppress the little ridging in place over the southeastern US. This will allow for the upper low over the Desert Southwest to track east into the Texas Panhandle. Should start to see mid level temps drop as the upper low reaches the Texas Panhandle which will open the door for hail to start to develop. That'll hold back any stronger winds to the southwest of the upper low.
1048 PM CST Fri Mar 7 2025 - Warmer temperatures today, then much cooler on Saturday.
The wind shift will support moisture advection across the region, but weak ridging and remnant dry air aloft will help to inhibit any shower development. Overnight lows will dip to the low to mid 60s. This system will push eastward, dragging another cold front along with it towards the Florida peninsula.
322 AM EST Sat Mar 8 2025 A weakening frontal system passes to our south early this morning, with a weak cold front quickly following.
Apart from that, any precipitation today and tonight will be very light, on accordance with the low level dry airmass already locked in place across the region.
1210 AM EST Sat Mar 8 2025 (06Z TAFS) VFR conditions will continue through Saturday as dry, high pressure remains in control. A cold front will approach Sunday night, leading to a window for impacts at area terminals as showers and potentially some thunderstorms arrive in the area.
Another mid level trough was located over Arizona this afternoon at 20Z. The mid level trough over Arizona this afternoon is forecast to move east into the southern Plains on Saturday, tracking along the Red River Saturday night. With the departure of the system moving off to the southeast Sunday and ridging building into eastern Kansas mostly sunny skies are expected.
A mostly zonal flow is in place across the SE CONUS as a ridge of high pressure slides to the east. Daytime highs will be a few degrees warmer today, and dewpoints will continue to slowly increase as well.
337 AM EST Sat Mar 8 2025 A big warmup today will be followed by a dry cold frontal passage early this evening.
1102 PM CST Fri Mar 7 2025 - Temperatures will trend warmer over the next few days, with rapid snowmelt ongoing.
The highest chances (60-70%) will occur overnight across north MS.
(This evening through Saturday) A slight warming trend will continue through the weekend as high pressure builds over the Pacific Northwest. After a chilly start to the day, Saturday afternoon will be slightly warmer with temperatures across the interior warming into the upper 60s to near 70 degrees F.
1137 PM CST Fri Mar 7 2025 - Slightly cooler conditions return Saturday.
1156 PM CST Fri Mar 7 2025 (This evening through Saturday night) Upper level analysis currently shows zonal to very mild ridging across much of the US east of the Rockies and a closed low near Arizona. Going into Saturday, a trough dipping out of Canada across the northeastern US will suppress the little ridging in place over the southeastern US. This will allow for the upper low over the Desert Southwest to track east into the Texas Panhandle. Should start to see mid level temps drop as the upper low reaches the Texas Panhandle which will open the door for hail to start to develop. That'll hold back any stronger winds to the southwest of the upper low.
Synopsis: Surface analysis early this morning shows low pressure over KY and WV. A large area of high pressure was found over NB and KS, building eastward. Radar shows light rain showers with the departing low pressure system continuing to exit southeast. The high and the subsidence in place aloft will continue to result in dry weather and mostly clear skies. Thus a clear sky will be expected, with lows in the lower to middle 30s as westerly winds and warm air advection beginning.
High pressure across Florida and the Bahamas continue to drive eastward further into the Atlantic. Cooler waters and earlier day time heating has let winds slip to the northeast. Parts of the Keys remain near 70, while the back yard has dipped into the lower 60s, quite close to the dew point. Stable conditions will remain with deep layered ridging remaining nearby. High pressure across Florida and the Bahamas will drive eastward into the Atlantic overnight.
An upper level short wave trough across the mid MS Valley will continue to get sheared out and weakened across the southern Great Lakes this evening under the influence of a strong deformation zone. Seasonable temperatures are expected on Saturday as western extent of low level thermal troughing lingers across the region. Some moderation in temperatures is expected on Sunday as upper level longwave ridging across western CONUS begins to shift eastward across the Rockies.
Daytime temperatures above freezing will also lead to an increased potential for ice jams and flooding of area rivers. Sunday will be warmer yet as next clipper tracks well to the north, placing Wisconsin in the warm sector.
944 PM MST Fri Mar 7 2025 - High pressure builds in Saturday and lingers through the weekend bringing sunny skies and above normal temperatures.
Weak surface ridging will quickly traverse the region this morning, before sliding to the southeast this afternoon.
1127 PM CST Fri Mar 7 2025 Updated at 1123 PM CST Fri Mar 7 2025 - Scattered showers will move through the Mid-South Saturday into Sunday morning, with the highest chances (60-80%) occurring across north MS.
VFR with high pressure aloft and at the surface. An upper-level ridge of high pressure will build over the region from the west, bringing a stretch of warm and dry conditions through the weekend. The ridge will promote mostly clear skies and above- normal temperatures across the area. The warming on Sunday will be further enhanced by strengthening easterly winds, which will develop as an upper-level low pressure system approaches from the west. While temperatures will climb well above seasonal averages, overnight lows will still drop near or below freezing in some sheltered valleys.
As surface ridging crosses the region, a mostly clear sky and quiet weather is expected this afternoon through tonight, with generally below-normal temperatures forecast. Current guidance suggests lows Sunday night range from the low to mid 30s across the region, though there is certainly potential for those temperatures to end up verifying a bit cooler (upper 20s to low 30s) as models sometimes struggle with efficient radiative cooling under light winds and mostly clear skies.
518 AM CST Sat Mar 8 2025 - Cooler today with scattered showers and storms.
- An upper level disturbance and cold front will bring high chances of showers and thunderstorms today.
620 AM EST Sat Mar 8 2025 A big warmup today will be followed by a dry cold frontal passage early this evening.
204 AM MST Sat Mar 8 2025 - High pressure builds in Saturday and lingers through the weekend bringing sunny skies and above normal temperatures.
232 AM MST Sat Mar 8 2025 KEY MESSAGES: - Mild temperatures this weekend under high pressure. Satellite imagery this morning across the region highlights a large ridge of high pressure building across the Pacific Northwest and Northern Rockies, with high clouds streaming from the northwest. South-southwest winds will develop Sunday afternoon and evening, with gusts of 15-25 mph in valleys and 30-45 mph across the higher terrain, especially in northwest Montana, as the gradient tightens with an approaching Pacific cold front in eastern Washington.
Cold front is beginning to work its way through the area now, so I'm uncertain how much additional warming will be able to take place for those locations today but bumped high temperatures up a tad to compensate and blended in with current observations. Apart from that, any precipitation today and tonight will be very light, on accordance with the low level dry airmass already locked in place across the region.
Sunday will be warmer yet as next clipper tracks well to the north, placing Wisconsin in the warm sector.
A ridge of high pressure will broadly support quiet, dry, mostly clear/sunny, low-impact weather across southeast Idaho over the next several days. A few patches of freezing fog may be lurking this morning, and varying high clouds may drift through at times, but that's it during this solid break between storm systems.
High pressure will build into the region through the weekend.
951 AM EST Sat Mar 8 2025 A big warmup today will be followed by a dry cold frontal passage early this evening.
Scattered snow showers will linger over eastern Arizona this morning, with otherwise clearing skies and a bit warmer temperatures today.
A rather uneventful night compared to last, with no precipitation and temperatures in the low 30s where there is no snow cover and in the low teens where a decent snowpack remains (northwest Wisconsin). On Sunday, low 60s are likely near the snow-less Buffalo Ridge, with mid to upper 50s elsewhere.
701 AM EST Sat Mar 8 2025 A weakening frontal system passes to our south early this morning, with a weak cold front quickly following.
405 AM MST Sat Mar 8 2025 - High pressure builds in Saturday and lingers through the weekend bringing sunny skies and above normal temperatures.
925 AM EST Sat Mar 8 2025 A cold front passes through the area this morning, followed by high pressure building in from the west through Sunday morning.
Daytime temperatures above freezing will also lead to an increased potential for ice jams and flooding of area rivers.
(Rest of today through Sunday night) Passage of a cold front this Saturday morning has brought cooler and breezy conditions with partly to mostly sunny skies. A veil of mid and high clouds will spread overhead, out ahead of a compact low pressure system over TX/OK. The compact low will move across the Lower Ms Valley and Deep South tonight through Sunday night. The higher chances will be along the Tennessee/Alabama border.
Winds will be largely out of the north before shifting to be northwesterly with the upper-level trough moving out of the area overnight. Clouds will follow behind the system, allowing for near freezing temperatures is our far northern zones and low 40s in the southeast.
There are some mid to high-level clouds over Central Alabama today, but moisture is still on the lower end. Rain chances will increase overnight as the low moves closer with the highest PoPs focused across the southern half of the area. Because the low is tracking south of the CWA, instability and overall moisture quality won't be particularly high by any means. Several of the hi-res models show somewhat of a decrease in coverage of showers tomorrow morning before forcing becomes reinvigorated late in the afternoon or into tomorrow evening as the mid to upper-level low begins to arrive over the Lower MS River Valley. Warmer air will remain along the Gulf coast, so highs tomorrow will range from the mid 50s north to lower 60s south.
Clearing skies should allow temperatures to drop to near or below freezing overnight. On Sunday, high pressure builds into the region from the north. 2) Diminishing winds tonight with freezing/near freezing temperatures. A cold front had pushed through the region today, and lingering upslope stratus over the mountains was gradually breaking up. Increasing cirrus is expected towards the morning and all day Sunday as a band of vorticity and jet energy sets up over the southern Appalachians, in advance of a low pressure system moving through the Gulf Coast states. Looking for highs in the low to upper 50s tomorrow from the mountains to the piedmont.
Though it's taken much the day, the snow cover just north of the Highway 30 corridor in Iowa appears that it's on track to melt completely by this evening. Highs in the upper 50s to lower 60s are well supported by tightly clustered guidance, with somewhat of a tail towards warmer readings.
An upper-level high pressure ridge will bring warm, dry conditions to the region today and Sunday. Strengthening easterly winds, developing as an upper-level low pressure system approaches from the west, will enhance Sunday's warming.
Midday surface map indicated elongated ridging stretched east from the central Rockies to the lower Ohio Valley. West-northwest winds around 10 mph northeast of the ridge axis provided weak cold advection, though with full sunshine temperatures were already pushing near 50F. As the ridge sinks southeast tonight and Sunday, winds back southwest, signaling the start of a warmup.
In all, expecting a warmer than average day across the Florida Keys with collapsing breezes later in the afternoon.
914 AM PST Sat Mar 8 2025 A chilly morning, with areas of frost in the valleys, will give way to a warmer day with dry conditions. Tomorrow will be even warmer with high temperatures reaching the mid seventies in the inland valleys.
A pleasantly dry air mass remains over the local area with highs topping out a few degrees warmer than yesterday. As we head into Sunday, conditions continue to warm and moisten as the pattern aloft amplifies, with a cut-off low moving across the southeast along with a surface reflection forming along the northern Gulf coast.
333 PM EST Sat Mar 8 2025 High pressure will prevail through the early part of the week along with a warming trend. Winds will drop off early but then increase in the latter part of the night as a trough passes across the Great Lakes causing the pressure gradient to tighten. Lows will generally be in the lower 30s. Warming trend will have commenced with highs in the lower to mid 50s and lows in the lower to mid 30s.
1108 AM EST Sat Mar 8 2025 At the time of this update, the cold front has just passed south of Knoxville and the I-40 corridor. Apart from that, any precipitation today and tonight will be very light, on accordance with the low level dry airmass already locked in place across the region.
- Elevated to critical fire weather conditions tonight and Sunday behind a cold front. A cold front is currently making its trek across South Texas, and will eventually reach the coast by the evening hours. As high pressure builds in overnight, temperatures will cool significantly, with overnight lows dipping into the mid 40s to low 50s. By Sunday, cooler conditions will persist, with highs reaching the upper 60s to lower 70s. Overnight temperatures on Sunday will fall into the low to mid 40s under mostly clear skies.
1143 AM CST Sat Mar 8 2025 - Cooler today with scattered showers and storms.
- An upper level disturbance and cold front will bring high chances of showers and thunderstorms today. However, still expected to see an increase in shower/thunderstorm activity through the afternoon as the cold front/low pressure system draws closer.
1023 AM MST Sat Mar 8 2025 - High pressure builds in Saturday and lingers through the weekend bringing sunny skies and above normal temperatures.
Tonight and Sunday High pressure continues to dominate the weather across eastern Idaho allowing for a pleasant late winter weekend. The lone exception to this is across the upper Snake Plain, near Idaho Falls and Rexburg, where overnight stratus and fog has continued to linger keeping temperatures closer to the freezing mark still.
1244 PM MST Sat Mar 8 2025 KEY MESSAGES: - Mild temperatures this weekend under high pressure. High pressure will bring a mix of clouds and sun into Sunday with daytime temperatures running 5 to 10 degrees above normal. South-southwest winds will develop Sunday afternoon and evening, with gusts of 15-25 mph in valleys and 30-45 mph across the higher terrain, especially in northwest Montana, as the gradient tightens with an approaching Pacific cold front in eastern Washington.
This area of low pressure will move east heading into Sunday with a warm front retreating along the Interstate 10 corridor in North Florida which will allow South Florida to fall within the warm, moist sector ahead of a frontal boundary associated with the low that will stretch into the Gulf. This moist airmass will contrast with drier and cooler air aloft to produce an increase chance of fog development tonight into Sunday with a focus along the Gulf coast and inland portions of the area. This system will push eastward, dragging another cold front along with it towards the Florida peninsula.
1254 PM EST Sat Mar 8 2025 Following a cold frontal passage, high pressure will gradually build in from the west through Sunday morning. The center of the high passes well south on Sunday, while weak low pressure passes to the north.
1214 PM EST Sat Mar 8 2025 At the time of this update, the cold front has just passed south of Knoxville and the I-40 corridor. Apart from that, any precipitation today and tonight will be very light, on accordance with the low level dry airmass already locked in place across the region.
-Much cooler temperatures Sunday. A cold front will move through this afternoon/evening bringing dry air and cooler temperatures to Deep South Texas. A cold front is currently just starting to move into northwestern Zapata county as of this writing and will move through the entire CWA later this evening. In wake of the cold front, breezy northwesterly winds are expected this afternoon and again on Sunday. Along with the windy conditions and drier air, much cooler temperatures are expected. Tonight, temperatures will fall into the low to mid 50s and Sunday high temperatures will only reach the low to mid 70s. While this is not too far below normal for this time of year, some locations will be around 15 degrees cooler than Saturday.
Also refreshed sky cover, with a diminishing stratocu field expected into the evening as surface ridging builds in.
209 PM PST Sat Mar 8 2025 Dry and warmer this afternoon with temperatures significantly higher than yesterday. Tomorrow will be even warmer with high temperatures reaching the mid seventies in the inland valleys.
The highest chances (60-70%) will occur overnight across north MS where a few rumbles of thunder are possible.
The Keys remain embedded within the northern flank of deep layered ridging, keeping precipitable water around. Stable conditions with mostly clear skies will remain with deep layered ridging and Cuban enhanced inhibition lingering. An Atlantic ridge reaching westward across South Florida and residual day time heating has resulted in light and variable breezes on Keys waters this evening. Wind should become light southerlies as the mainland cools, the ridge retreats further to the east, and troughing slips eastward across the Gulf.
Sunday through Sunday night: The closed upper low traversing the Deep South will be the primary weather driver as we finish up the weekend. Moist ascent will be most pronounced in the deformation zone north of the low center, which is expected to move into northwest portions of the area Sunday afternoon then track to east central MS by late Sunday night.
420 PM MST Sat Mar 8 2025 - Clear skies under high pressure will see seasonably warm temperatures return through the beginning of week.
Also refreshed sky cover, with a dminishing stratocu field expected into the evening as surface ridging builds in.
After another dry and warm day Sunday, we will transition into a cooler and more active pattern.
639 PM EST Sat Mar 8 2025 High pressure will prevail through the early part of the week along with a warming trend. Winds will drop off early but then increase in the latter part of the night as a trough passes across the Great Lakes causing the pressure gradient to tighten. Lows will generally be in the lower 30s. Warming trend will have commenced with highs in the lower to mid 50s and lows in the lower to mid 30s.
Additionally, I bumped up winds once the cold front moves through. - Elevated to critical fire weather conditions tonight and Sunday behind a cold front. A cold front is currently making its trek across South Texas, and will eventually reach the coast by the evening hours. As high pressure builds in overnight, temperatures will cool significantly, with overnight lows dipping into the mid 40s to low 50s. By Sunday, cooler conditions will persist, with highs reaching the upper 60s to lower 70s. Overnight temperatures on Sunday will fall into the low to mid 40s under mostly clear skies.
240 PM MST Sat Mar 8 2025 - Clear skies under high pressure will see seasonably warm temperatures return through the beginning of week.
High pressure east of the Florida peninsula will continue to move away from the region tonight and Sunday with south to southwest boundary layer flow advecting warm moist air over the forecast area. An area of low pressure will develop near the Louisiana coast tonight and will ride along the frontal boundary across the northern Gulf coast through Sunday.
High pressure will build into the region through the rest of the weekend.
Temperatures were steady in the lower to mid 70s except over a few sheltered interior locations, where the Big Pine Key Deer NWR RAWS was near 65F and Ocean Reef managing to hold steady in the upper 60s.
936 PM MST Sat Mar 8 2025 - Clear skies under high pressure will see seasonably warm temperatures return through the beginning of week.
421 AM EDT Sun Mar 9 2025 High pressure will build into the region from the north today.
500 AM EDT Sun Mar 9 2025 High pressure will build into the region from the north today.
150 AM MST Sun Mar 9 2025 - High pressure will bring sunny skies and seasonably warm temperatures into the early part of the week.
141 AM EST Sun Mar 9 2025 - Sunny and warmer today; Mostly Clear tonight. Synopsis: Surface analysis early this morning shows a broad, elongated area of high pressure stretching from KS and MO to the Ohio Valley. Low pressure was found south of Louisiana. Aloft, strong ridging was in place over CA and NV, with quick NW flow spilling from that ridge across the upper midwest and into Indiana and Ohio. Models show the elongated high pressure area remaining over Indiana and the Ohio valley. This is mainly due to subsidence remaining in play due to the deep upper low passing across the deep south and ongoing lee side subsidence amid the northwest flow in place aloft.
While temperatures remain quite warm under clear skies this afternoon, temperatures will be cooler tomorrow (Sunday) thanks to increasing cloud cover and onset of rain.
332 AM EDT Sun Mar 9 2025 High pressure will prevail through the early part of the week offering dry weather along with a warming trend. Warming trend will to continue with highs from the lower 50s north to the upper 50s south. Low temperatures in the lower and middle 30s. In dry airmass -- abundant sunshine and WAA will allow temperatures to warm to highs in the lower and middle 60s.
