(12Z TAFS) Low clouds and gusty winds this morning will linger as a line of storms ahead of a cold front moves closer to the area.
929 AM EDT Sun Mar 16 2025 Showers and a few thunderstorms will be possible today as a cold front moves east across the Ohio Valley. High pressure and a dry but cooler airmass will then settle into the region for the start of the workweek. Temps should be slowly falling through the daytime with the FROPA, with temps already into the lower 40s across EC IN and WC OH. A few showers may linger into this evening across our east until we get on the back side of the upper level trough axis. This will lead to dry but cooler conditions.
1059 AM EDT Sun Mar 16 2025 - Colder with light snow today - Warmer mid week, then colder again The forecast remains on track this morning, with no noticeable changes needed at this time. Latest surface analysis shows low pressure over central IN moving northeast. As this low moves toward DET, it'll drag a cold front that extends from Saginaw southwest to Marshall through the rest of the cwa and colder air will continue to pour into the cwa. Radar shows quite a bit of precipitation yet to fall as the upper low is near STL.
Southerly to southwesterly low level winds will bring warmer air and limited moisture to the area.
As the main trough begins to east by tonight, cold air advection will quickly work its way into the region. Overnight lows on Sunday will drop into into the mid to upper-30s, with highs on Monday ranging in the low to mid-60s. There is a chance that some rain could wrap around the low pressure back into the region on Sunday afternoon, but outside of that the rest of the short-term looks to remain dry.
411 AM CDT Sun Mar 16 2025 Updated at 400 AM CDT Sun Mar 16 2025 - Cooler and drier air air will filter into the Mid-South today. Temperatures are expected to drop into the lower to middle 30s across many locations tonight.
643 AM EDT Sun Mar 16 2025 Showers and a few thunderstorms will be possible today as a cold front moves east across the Ohio Valley. High pressure and a dry but cooler airmass will then settle into the region for the start of the workweek. As it does, an attendant cold front will push east across our area later this morning into early afternoon. Will then linger some scattered showers into this afternoon as the upper level trough axis moves east across the region. A few showers may linger into this evening across our east until we get on the back side of the upper level trough axis. This will lead to dry but cooler conditions.
138 PM EDT Sun Mar 16 2025 Showers and a few thunderstorms will be possible today as a cold front moves east across the Ohio Valley. High pressure and a dry but cooler airmass will then settle into the region for the start of the workweek. Temps should be slowly falling through the daytime with the FROPA, with temps already into the lower 40s across EC IN and WC OH. A few showers may linger into this evening across our east until we get on the back side of the upper level trough axis. This will lead to dry but cooler conditions.
(Rest of Today) The base of an upper trough is currently pushing across the lower Mississippi Valley and Deep South region, with a cold front currently moving across the Tennessee Valley. These northwest winds will help to reinforce a cooler air mass, as highs will peak in the low to mid 60s this morning, before falling a few degrees by the late afternoon and evening.
1200 PM CDT Sun Mar 16 2025 (Rest of Today) The base of an upper trough is currently pushing across the lower Mississippi Valley and Deep South region, with a cold front currently moving across the Tennessee Valley. These northwest winds will help to reinforce a cooler air mass, as highs will peak in the low to mid 60s this morning, before falling a few degrees by the late afternoon and evening.
201 PM CDT Sun Mar 16 2025 Updated at 155 PM CDT Sun Mar 16 2025 - Cooler and drier air air will filter into the Mid-South today. Temperatures are expected to drop into the lower to middle 30s across many locations tonight.
246 PM CDT Sun Mar 16 2025 - Another system will bring snow across the northern half of the state tonight into Monday, with the possibility for freezing rain/drizzle across central North Dakota.
1244 PM CDT Sun Mar 16 2025 Updated at 1235 PM CDT Sun Mar 16 2025 - Cooler and drier air air will filter into the Mid-South today. Temperatures are expected to drop into the lower to middle 30s across many locations tonight.
Sfc cold front and associated showers finally pushing their way through the Bluegrass region, with the cold pool aloft and enough trapped moisture sustaining drizzle as far west as Corydon and Brandenburg. Upper trof passes around midnight, but clouds will hang on for much of the overnight, even a little past daybreak in the Bluegrass region.
1223 PM CDT Sun Mar 16 2025 - Dry fuels, increasing winds, and warmer temperatures will lead to very high grassland fire danger Monday in central South Dakota.
This will combine with sunny skies allowing warmer temperatures to develop across the region for tomorrow afternoon. Tonight's low temperatures will be in the lower to middle 40s.
1029 AM CDT Sun Mar 16 2025 - Dry fuels, increasing winds, and warmer temperatures will lead to very high grassland fire danger Monday in central South Dakota.
307 PM EDT Sun Mar 16 2025 A cold front pushes through this afternoon with some showers/storms.
318 PM CDT Sun Mar 16 2025 - Light freezing rain is possible along and just south of the Highway 2 corridor tonight. There is a 60 percent chance for 1 inch or more snow along and north of the Highway 2 corridor.
(Tonight) Cooler today than it was yesterday with highs reaching the upper 50s to lower 60s. A reinforcing cold front is pushing through the TN Valley at this hour with westerly winds gusting ahead of it and northwesterly winds also gusting 20-25kts behind it. Northwesterly winds aloft will also push in some cooler air as the base of an upper level trough moves on out. Combined with drier air filtering in, decreasing cloud cover overnight will drop lows into the lower 30s. Yep, that's right, freezing temperatures are expected tonight so bundle up tonight and for the bus stop in the morning.
/SEC (Today through Monday) Broken line of convection out ahead of a cold front continues to move east across the CWA early this morning. 500mb longwave trough will move through the southeast states today. At the surface, the cold front is currently situated across east central AL and moving east. High pressure will build back in behind the front(s).
Temperatures behind the front are modestly cooler, but one thing that is for sure is the dryness in the air. In fact, last hour here at ASD the dewpoints had dropped into the lower 30s. A broad scale trough will continue to move overhead with H5 dry northwest flow setting up, the short term will, indeed, be dry and nearly cloud free. At the surface, high pressure will spread into the region, which again will decrease winds overnight and allow us to cool back into the 40s for most of the CWFA. A cooler start than what we experienced today and a slightly warmer by two or three degrees afternoon is expected with much less in the way of breezy conditions.
318 PM EDT Sun Mar 16 2025 A cold front crossing the region will introduce cooler air tonight and Monday.
210 PM EDT Sun Mar 16 2025 A cold front pushes through this afternoon with some showers/storms.
Surface analysis places the Florida Keys in the warm sector ahead of a strong cold front extending from the Bay of Campeche northeastward to the Florida Panhandle. The southerly steering flow, combined with the ample sunshine, has supported temperatures climbing into the lower to mid 80s. Coupled with dew points in the lower to mid 70s, a muggy mid-March day for the Keys. The aforementioned cold front will push through the Florida Keys from west to east in the late overnight and early morning time frame.
A few snow showers are possible early Monday before high pressure returns dry and warmer weather to the region through mid week. - Possible snow overnight - Gusty wind ------------------------------------------------------------------- A cold front currently crossing through the forecast area should be east of the ridges by this evening. Cold advection will ramp up by late evening after a reinforcing cold front crosses the region. No accumulation is expected for most of the area, though an inch or less is possible across the higher terrain areas.
347 PM EDT Sun Mar 16 2025 High pressure will settle into the region tonight through Monday, providing dry conditions through midweek.
242 PM EDT Sun Mar 16 2025 High pressure will settle into the region tonight through Monday, providing dry conditions through midweek.
1205 PM CDT Sun Mar 16 2025 (Today through Monday Night) A cold front pushed through the state on Sat afternoon. with drier and cooler air pushing into the state. Even with temps cooler in the 50s and 60s for highs this afternoon.
A secondary dry cold front will sweep across the service area early this evening, followed by a turn to northwest winds, with a more genuinely cold air mass spreading across the region tonight.
Upper ridge will be moving off to the east this afternoon, allowing for southwest flow over the forecast area. Upper trough will be pushing into portions of northern Nevada through the overnight and into mid- morning tomorrow. The main trough is expected to move across northern and central Nevada during the overnight on Monday.
238 PM EDT Sun Mar 16 2025 High pressure will settle into the region tonight through Monday, providing dry conditions through midweek.
There are moderate winds (gusts of 30 to 50 mph) still across the area, especially ridgetops, the Snake River plain, and the Arco desert.
113 PM EDT Sun Mar 16 2025 - Colder with light snow today - Warmer mid week, then colder again The forecast remains on track this morning, with no noticeable changes needed at this time. Latest surface analysis shows low pressure over central IN moving northeast. As this low moves toward DET, it'll drag a cold front that extends from Saginaw southwest to Marshall through the rest of the cwa and colder air will continue to pour into the cwa. Radar shows quite a bit of precipitation yet to fall as the upper low is near STL.
1145 AM CDT Sun Mar 16 2025 Quiet forecast is on tap as zonal flow & sfc ridging build across the region.
Road temps have dropped to near freezing up there. As far the rain and snow trends are concerned, the cooler air can be seen oozing in from west to east as rain has now changed to snow at Grand Rapids. Road temps are warmer away from the NW areas, and this should limit the potential impact most places would see from snow. Otherwise, a fairly broad scale ridge over most of the Western U. this afternoon will build east in the wake of the low moving out.
/22 High pressure will slowly move east across the area through midweek under a northwest upper level flow.
The highest RH around is mid 20% range at Downtown Shreveport and Natchitoches. High pressure is 1020mb right next door at Corsicana with calm wind in the DFW metroplex for a change of pace. The skies will be clear with radiational cooling super charged in this dry air, but records (some 10 degrees cooler) will be quite safe. Highs will rebound in the sun and warmer wind, a good 30 to 40+ degrees by late afternoon.
137 PM EDT Sun Mar 16 2025 A strong low pressure system impacts the area today, with strong, heavy thunderstorms possible.
Pattern Synopsis and Forecast: Low pressure system departs to the northeast tonight as west flow aloft becomes more established. High pressure shifts to the east, decaying low pressure across the Plains/Upper Midwest, thus winds will shift southerly. Pattern Synopsis/Forecast: Longwave troughing will continue to shift eastward as a ridge of high pressure builds into the Great Lakes region at the start of the period.
The NW winds are making it feel a little cooler. /24/ (Sunday through Monday) High pressure to build east across the region today with northerly winds around 10 mph with higher gusts expected. High temperatures on Monday to average in the low to mid 70s.
Updated at 210 PM CDT Sun Mar 16 2025 - Warmer today with quiet weather expected.
1103 AM EDT Sun Mar 16 2025 Showers and thunderstorms are expected today as a strong cold front crosses the region. A few snow showers are possible early Monday before high pressure returns dry and warmer weather to the region through mid week. KEY MESSAGES: - Strong cold front crosses today - Showers and thunderstorms expected - Severe storms possible, with damaging wind and isolated tornadoes - Gusty wind outside of thunderstorms ------------------------------------------------------------------- A cold front currently crossing through central Ohio will cross the region, with convection developing ahead of the front late this morning and into the afternoon. The low's surface cold front is progged to cross the region by mid to late afternoon.
Quiet forecast is on tap as zonal flow & sfc ridging build across the region.
738 PM EDT Sun Mar 16 2025 High pressure will settle into the region tonight through Monday, providing dry conditions through midweek.
- Clearing and cold tonight with sub-freezing temperatures.
A few snow showers are possible early Monday before high pressure returns dry and warmer weather to the region through mid week. Cannot rule out another few instances of wind damage from these storms before the lower levels stabilize this evening. Cold advection will ramp up by late evening after a reinforcing cold front crosses the region. No accumulation is expected for most of the area, though an inch or less is possible across the higher terrain areas.
657 PM CDT Sun Mar 16 2025 - Another system will bring snow across the northern half of the state tonight into Monday, with the possibility for freezing rain/drizzle across central North Dakota.
1000 PM CDT Sun Mar 16 2025 - Light freezing rain is possible along and just south of the Highway 2 corridor tonight. There is a 60 percent chance for 1 inch or more snow along and north of the Highway 2 corridor.
Things are quiet and much cooler across the CWA at this hour. Expect winds to steadily drop off through the overnight, and given some clearing of the low clouds, do think we might be able to radiate out across our west fairly well. Farther east, we may hang onto the low 30s where clouds stay in a bit longer. Sfc cold front and associated showers finally pushing their way through the Bluegrass region, with the cold pool aloft and enough trapped moisture sustaining drizzle as far west as Corydon and Brandenburg. Upper trof passes around midnight, but clouds will hang on for much of the overnight, even a little past daybreak in the Bluegrass region.
Tonight will be warmer with near normal lows under increasing cloud cover. Warmer Monday with highs 6-10 degrees above normal and breezy afternoon weather southeast of Tucson.
836 PM EDT Sun Mar 16 2025 A cold front pushes through this afternoon with some showers/storms.
417 PM CDT Sun Mar 16 2025 - It will be much warmer on Monday, though humidity will be very low.
(Rest of Tonight) Cooler today than it was yesterday with highs reaching the upper 50s to lower 60s. A reinforcing cold front is pushing through the TN Valley at this hour with westerly winds gusting ahead of it and northwesterly winds also gusting 20-25kts behind it. Northwesterly winds aloft will also push in some cooler air as the base of an upper level trough moves on out. Combined with drier air filtering in, decreasing cloud cover overnight will drop lows into the lower 30s. Yep, that's right, freezing temperatures are expected tonight so bundle up tonight and for the bus stop in the morning.
pdf Lingering showers ahead of cold front will diminish this evening. Lows will range from the middle 40s inland to the lower 50s east coast and north central FL.
642 PM CDT Sun Mar 16 2025 - Light freezing rain is possible along and just south of the Highway 2 corridor tonight. There is a 60 percent chance for 1 inch or more snow along and north of the Highway 2 corridor.
1021 PM EDT Sun Mar 16 2025 High pressure will settle into the region tonight through Monday, providing dry conditions through midweek.
A closed low will remain over Arizona this weekend. Light rain showers will continue to wrap back westward around the low into northwest Arizona today, less so Sunday. Dry and warmer conditions will persist through the upcoming week. The upper low continues to meander around central Arizona this morning. A band of weak showers and sprinkles can be seen on radar rotating around the back side of the trough and across the eastern portions of Clark County. Satellite shows the closed low over north central Arizona wobbling westward slightly since late last evening. On Sunday, a few light showers may continue to wrap back westward into northern Mohave County around the slowly weakening closed low.
High temperatures today are expected to be 5 to 10 degrees warmer than yesterday for most places. High temperatures for inland areas will increase a few degrees each day through the middle of the week as an area of weak high pressure builds over Southern California.
The ridging should start to be pushed further east into the new week as a weak disturbance enters the Midwest.
Expect lows to dip into the lower to middle 40's inland and upper 40's and lower 50's nearer the coast both nights. Highs tomorrow will be a tad warmer, topping out in the upper 70's over the interior and lower 80's across southeastern Mississippi into coastal sections of Alabama and the Florida Panhandle.
With the return of weak onshore flow Sunday, highs near the coast may be a degree or two cooler than today but additional warming is expected for inland locations.
One of the more notable features on water vapor imagery this afternoon is cut-off low spinning over the Southwest. Latest surface analysis shows mesoscale high pressure to our south, centered over central NE, with a subtle trough crossing the region from west to east. Relative positioning of trough and high pressure is supporting steady southwesterly flow over the SD plains, with more variable and terrain-driven flow near the Black Hills into northeastern WY. With deep high pressure over the Southeastern quarter of the CONUS and modest troughing over and east of the Rockies, predominantly west/southwest flow over the region will facilitate warming low- level temperatures.
A ridge of high pressure remains resilient over eastern Kentucky, leading to present conditions persisting through the weekend. Highs in the lower 70s can be expected this afternoon, with clear skies and lows in the mid to upper 30s for valleys, and mid to upper 40s along ridges at night. Tomorrow could be considered a carbon copy day in regard to weather, with sunny skies under light and variable winds and afternoon highs in the low 70s.
Temps in the upper 60s to low 70s will warm maybe a couple more degrees but highs today are expected to be in the low 70s for much of the area.
- Dry and cooler weather is expected around mid-week, with highs in the 60s. Lows will fall into the low to mid-50s. Heading into Sunday, a closed upper low will be centered over northeastern Arizona by daybreak, crossing over the Four Corners region in the evening.
Discussion: A strong ridge of high pressure will remain in control.
A closed low will remain over Arizona this weekend. The closed upper level low in Arizona will move north into north central Arizona this evening and provide one last round of light showers to mainly the eastern portions of Mohave County this evening and overnight. The low will begin to eject to the east during the day on Sunday.
1229 PM CDT Sat Oct 19 2024 - Highs in the low to mid 70s today with mostly overcast skies.
1230 PM EDT Sat Oct 19 2024 High pressure will persist over the area through the weekend before gradually shifting towards the Mid-Atlantic Coast by midweek.
Surface analysis shows broad high pressure ridging over the OH Valley southwest into TX. Ridging extends into the mid levels per WV imagery and UA analysis, with a very dry airmass over the region.
Early afternoon satellite imagery shows mostly clear skies across ERN Idaho under the increasing influence of high pressure. Following a series of cold fronts earlier this week, temperatures have responded accordingly with highs both today and Sunday in the 50s/60s which are near normal to slightly above normal levels for this time of year. Overnight lows tonight will be similar to last night in the 20s/30s before trending slightly warmer Sunday night into the 30s/40s.
358 PM EDT Sat Oct 19 2024 High pressure remains in control for early week.
(This evening through Sunday) The upper low is currently situated over Arizona and is nearly stationary. Convection will mostly remain west of the FA this afternoon and tonight as the upper low remains in place. Some clearing is expected across the Rolling Plains late tomorrow morning into the afternoon as the upper low pushes northeastward into Utah.
Cloud cover increased this morning due to the passage of a weak upper-level trough, keeping temperatures slightly warmer in the lower Treasure Valley, with readings in the mid-30s. However, most locations in the Upper Treasure Valley experienced freezing temperatures. A warming and drying trend will persist through Sunday as an upper-level ridge develops over the region.
(This evening through Sunday Night) Upper-level ridging will continue to dominate the short-term, as it will move directly overhead by tomorrow afternoon. Highs tomorrow will range in the mid-70s to low 80s, with overnight lows remaining in the low-40s to low-50s.
Observations indicate gusty east-northeast winds are still ongoing along exposed Sierra ridges at time of writing, with strongest gusts upwards of 60-90 mph. However, an overall downward trend in ridgetop winds is expected through the remainder of the day, eventually becoming light overnight.
1243 PM CDT Sat Oct 19 2024 (Today through Sunday) A 592 decameter subtropical ridge will retrograde westward over the Gulf this weekend, while ridging also builds over the central CONUS east of a cutoff low over Arizona.
1238 PM CDT Sat Oct 19 2024 (Today through Sunday) An upper-level trough over the inter-mountain west will support southwesterly flow aloft through the short term period. Pressure gradients across the Northern Gulf continue to support increasing wave heights and long period swell along the Lower Texas Coast.
(Rest of today through Sunday) South Florida will remain under the influence of a moderate to strong surface and low-level NE wind flow between high pressure over the eastern U. and the frontal boundary stalled over the lower Florida Straits. In the mid-levels, the 500 mb high pressure near South Florida will shift west into the Gulf of Mexico over the next few days. By late tonight and early Sunday, some low level moisture will begin to move into the region from the NE on the back side of a low pressure area near Bermuda.
1227 PM CDT Sat Oct 19 2024 (Rest of Today) A rather deep low over the SW CONUS was producing deep troughing over the western states, while upper level high pressure over the Mid Atlantic region has pronounced ridging across the eastern states. High temperatures later this afternoon should rise into the low/mid 70s with light winds. Even warmer conditions are expected tomorrow with highs into the mid/upper 70s.
328 PM EDT Sat Oct 19 2024 High pressure will continue to predominate with temperatures above normal. A cold front will move through midweek with only a minimal chance of rain. Lows will be a few degrees warmer than last night. High pressure will persist. This period will feature high pressure and dry air for the most part, though a couple of weak systems will bring a low threat for showers.
209 PM EDT Sat Oct 19 2024 High pressure and dry conditions continue to dominate the region with normal or slightly cooler temperatures through Sunday. Key Message(s): - Dry and continued cooler than normal. Dry high pressure at the surface and aloft across the area. There is a weak mid level short wave trough lifting northeast thru the area with some very thin high clouds.
