Progressive high pressure will shift across the area this afternoon relaxing the gradients and northerly winds. Breezy Northwest winds at 15-20G25-30 mph will continue this morning with the passage of mid level trough axis with mainly sunny skies, except for some cold air advection Strato-Cu clouds across inland SE GA. High pressure builds directly overhead with clear skies and winds becoming near calm, which should set the stage for excellent radiational cooling conditions and expect low temps in the 36-39F range over inland areas of both NE FL and SE GA, this should be low enough to support some patchy frost formation just before sunrise Saturday morning, but likely not enough for the need for any Frost Advisory headlines.
The steady southeasterly flow will continue to advect moisture and warmer air into Deep South Texas resulting warming temperatures and increasing dewpoints through the first half of the weekend. Highs today will be in the low to mid 80s, except for the 70s at the beaches. Lows tonight are expected to fall into the upper 50s across the northern ranchlands to the low 60s across the Rio Grande Valley.
643 AM CDT Fri Mar 21 2025 - Warmer and windy today with southwest gusts between 30-40 mph, leading to an elevated fire danger.
- Next weather system races across Wyoming Friday night into Saturday, bringing another round of snow to the higher mountains.
709 AM EDT Fri Mar 21 2025 * Dry and mild conditions today with highs in the low 50s * A cold front tracks through tonight with temperatures dropping rapidly into the upper 20s to low 30s Saturday morning.
431 AM CDT Fri Mar 21 2025 Today through tonight: After a very chilly and frosty start to the day with many locations near to a little below freezing, temperatures will rebound quickly under full sun and increasing southerly wind.
Upper troughing extends southward along the eastern seaboard. On the surface, an area of low pressure moves eastward off the New England coastline, while the associated cold front extends southward through the western Atlantic and across south Florida. Cooler and drier air on the backside of this trough and front will advect into the region over the next 36 hours.
627 AM CDT Fri Mar 21 2025 High pressure centered over the deep south today, slips southeast across the eastern Gulf and across the FL Peninsula to open up the weekend. Saturday's numbers though, lifting up into the lower to mid 70's, will trend a few degrees warmer than normal. /10 The period beings with active weather associated with upper troughing digging across the eastern CONUS.
Main concern continues to be fire weather, given the low relative humidity values this afternoon especially north and east. Will be enough wind with the low RH to be at least marginal for an Elevated Fire Danger SPS in SW VA this afternoon, and will issue one for our SW VA counties with this update. Friday night will remain quiet with most locations expected to remain a few degrees above freezing thanks to increasing clouds ahead of a surface front.
- Vigorous Pacific cold front Friday afternoon into Saturday morning, with moderate to heavy mountain snow.
Ahead of the cold front, south to southwest winds will become gusty later this morning as vertical mixing increases beneath a low-level jet characterized by 30 to 50 knots of 925 to 850 mb flow. Given the post-frontal air mass will be modified by downslope- warming, no appreciable cool down is expected behind the cold front. As a matter fact, most locations will likely be warmer than yesterday. Wind speeds will also decrease behind the cold front as the 925 to 850 mb flow will be weaker behind the front than ahead of the front. However, given the recent fire activity, dry vegetation, the wind shift/cold front, and poor relative humidity recovery, a Red Flag Warning was issued where the strongest winds are expected today (along and southeast of I-44).
700 AM EDT Fri Mar 21 2025 High pressure builds in late tonight and Friday. A dry cold front moves through Saturday night. Cool and dry high pressure builds in today bringing mainly sunny skies. NW winds will continue to gust around 20-25 mph through the morning and early afternoon but will diminish rapidly later in the day as the high builds in.
Clear skies and southerly winds will aid in advecting in some warm Gulf air allowing for temps to rise into the low 60s across the area.
Winds have already begun to slowly weaken as of 18z, and will continue to diminish and become more easterly through the evening hours as broad surface ridging settles over Oklahoma. The highest confidence in breezy conditions with winds of 15 to 25 mph is currently over the far SW TX Panhandle, with hi-res consensus favoring lighter winds over the remainder of our area with some locations potentially seeing winds remain under 15 mph through most of the day. Regarding temperatures on Saturday, downslope surface flow and a well-defined low level thermal ridge will result in a very warm day, with highs expected to reach into the 80s across the entire forecast area.
125 PM MDT Fri Mar 21 2025 - Vigorous Pacific cold front tonight into Saturday morning, with moderate to heavy mountain snow.
1248 PM CDT Fri Mar 21 2025 - Scattered rain showers will found along and ahead of a cold front this afternoon and evening.
Upper level flow will transition more westerly for Saturday with warmer temperatures creeping up across the Panhandles.
The freezing level on this mornings sounding was 5500 feet which will put the snow level around 4500 feet. The highest precipitation amounts over the last 24 hours were focused along the coast, coastal mountains and Cascades, and this will remain the case through tonight. A slow moving cold front will bring a deterioration in conditions today into tonight, with the IFR/MVFR mix expected to become predominant. The next frontal disturbance is likely to continue areas of precipitation and the lower ceilings on Saturday.
Snow accumulations of 1 to 3 inches may be possible through morning, with the highest totals north of Cottonwood Pass.
The higher than normal 500 mb heights over the area will allow for our gradual warming trend of the past few days to continue through the weekend.
1245 PM CDT Fri Mar 21 2025 - Warmer and windy today with southwest gusts between 30-40 mph, leading to an elevated fire danger.
245 PM EDT Fri Mar 21 2025 Weak high pressure will build into the area through this evening. A cold front will cross the area Saturday evening.
217 PM MDT Fri Mar 21 2025 - Elevated to near-critical fire weather conditions ahead of a cold front Saturday afternoon.
High pressure will settle overhead tonight, allowing winds to calm and temperatures to drop tomorrow morning.
Expect another breezy/windy day tomorrow (Saturday) as a trough develops in the southern plains and the pressure gradient tightens once again. It will be warmer on Saturday with high temperatures ranging from the low 90s out west to the low 80s east under abundant sunshine and a slight westerly (subsident) component to the H85 flow. Dwpts will steadily rise into the low to mid 60s Saturday Night with a continued onshore flow resulting in mild and muggy conditions with lows in the 60s.
A slow moving cold front will bring maintain these conditions today into tonight, though there could be brief periods of improvement to MVFR/VFR this afternoon. The next frontal disturbance is likely to continue areas of precipitation and the lower ceilings on Saturday. The freezing level on this mornings sounding was 5500 feet which will put the snow level around 4500 feet. The highest precipitation amounts over the last 24 hours were focused along the coast, coastal mountains and Cascades, and this will remain the case through tonight.
156 PM PDT Fri Mar 21 2025 Weak high pressure will continue through Saturday with near to slightly above average temperatures.
329 PM EDT Fri Mar 21 2025 An upper level trough will approach from the west tonight. A surface cold front will cross southeast starting with the predawn hours on Saturday and exiting the region by late morning. The cold front will produce a low probability of showers as it passes.
120 PM EDT Fri Mar 21 2025 - Cold start this morning but becoming mild and dry as high pressure briefly builds into the mid Mississippi Valley.
1239 PM CDT Fri Mar 21 2025 High pressure centered over the deep south today, slips southeast across the eastern Gulf and across the FL Peninsula to open up the weekend. Saturday's numbers though, lifting up into the lower to mid 70's, will trend a few degrees warmer than normal. /10 The period beings with active weather associated with upper troughing digging across the eastern CONUS.
An upper trough and noted PV anomaly was approaching the Siouxland area this afternoon with high based convection beginning to develop within the upper low coreâs steep mid level lapse rates. With LFCs/LCLs both above the freezing level, small hail production may be enhanced with sublimation cooling below the high bases and enhancing gusty wind potential. Any precip should quickly exit eastern sections early this evening as subsidence behind the upper trough advances. Have lowered min temps there, lows into the teens north, but even cooler readings are possible. Temperatures should rebound again tomorrow however with return flow beginning and the current ND/MN cold front advancing no farther south than a glancing blow into the Upper MS Valley.
At the surface, high pressure was centered near Mobile.
200 PM EDT Fri Mar 21 2025 High pressure along the western edge of the Appalachians will keep a dry southwest flow over the Ohio Valley through this evening. Overnight, an upper level trough will approach from the west. A surface cold front will cross southeast starting with the predawn hours on Saturday and exiting the region by late morning. The cold front will produce a low threat of showers as it passes.
(Tonight) At the surface, high pressure will continue to build across the Gulf coast promoting high and dry conditions through the remainder of the day and through the night. Temps will only be able to fall into the high 30s and low 40s before sunrise as daytime heating takes over.
(This evening through Saturday) A weak cold front will move into the northern half of the area overnight, then dissipate.
Winds will be gusty Saturday, and afternoon relative humidity values will be on the low side with minimum values between 25 and 35 percent likely across much of the area. The lower RH values should be most widespread across portions of the central and southern TN Valleys where quite a bit of green up has occurred, and RH values are expected to be a bit higher north and mountains where less vegetation has broken dormancy.
Although we will have a cool start to the morning, high temperatures are expected to rebound into the low to mid 70s for most areas.
221 PM CDT Fri Mar 21 2025 - Scattered rain showers will be possible along and ahead of a cold front this afternoon and evening.
A warm front approaching from the west will spread precipitation into SE Oregon and far SW Idaho this afternoon. Locally breezy conditions develop later this afternoon, mainly in the higher elevations.
As of 2 pm, latest surface analysis indicates weakening gradients and thus decreasing winds as surface ridging noses in from the west. Temperatures continue to rise and should peak in the low/mid 60s this afternoon. Temperatures are expected to fall to the lower 40s and upper 30s inland, which may lead patchy frost from the Suwannee Valley into interior areas of southeast GA. High pressure will be overhead Saturday morning. The high will center more to the east Saturday afternoon through Saturday night, as a weak cold front passes to the north northeast.
144 PM EDT Fri Mar 21 2025 Dry and cooler conditions can be expected today, followed by rain and possible snow showers on Saturday.
256 PM EDT Fri Mar 21 2025 - A cold front this afternoon brings a brief round of mainly snow followed by lake effect snow showers over the north- northwest wind snow belts.
233 PM EDT Fri Mar 21 2025 Seasonably cool high pressure will build across the Southeast ahead of a moisture-starved frontal system that will move across and offshore the Middle Atlantic Saturday and Saturday night. High pressure will continue to build into the region from the south and west this evening. Highs will be seasonable, generally in the lower 60s. There will be an increase in high clouds late tonight and an uptick in the SW surface winds (ahead of the next trough that will approach from the west Saturday). Saturday, a dry cold front will move through the region, veering winds to westerly and northwesterly. Due to pre-frontal WAA, maximum temperatures should be warmer than today's, with highs expected to reach the lower 70s for most of central NC.
1228 PM EDT Fri Mar 21 2025 Dry and cooler conditions can be expected today, followed by rain and possible snow showers on Saturday.
Snow totals will be higher through our mid and upper elevation zones with about 2 to 4 inches in the mid elevations and 4 to 8 inches in the higher elevations. Up in the Island Park/Henry's Lake area, we are watching for some snow squall potential as the cold front moves through and gusts pick up. By Saturday evening winds should be backing off and most of the precipitation will be wrapped up with cooler air in place for Saturday night and temperatures falling into the teens and 20s for many.
545 PM EDT Fri Mar 21 2025 Seasonably cool high pressure will build across the Southeast ahead of a moisture-starved frontal system that will move across and offshore the Middle Atlantic Saturday and Saturday night. High pressure will continue to build into the region from the south and west this evening. Highs will be seasonable, generally in the lower 60s. There will be an increase in high clouds late tonight and an uptick in the SW surface winds (ahead of the next trough that will approach from the west Saturday). Saturday, a dry cold front will move through the region, veering winds to westerly and northwesterly. Due to pre-frontal WAA, maximum temperatures should be warmer than today's, with highs expected to reach the lower 70s for most of central NC.
447 PM MDT Fri Mar 21 2025 - Elevated to near-critical fire weather conditions ahead of a cold front Saturday afternoon.
820 PM EDT Fri Mar 21 2025 High pressure will build across the Southeast ahead of a moisture- starved frontal system that will move across and offshore the Middle Atlantic Saturday and Saturday night. Saturday, a dry cold front will move through the region, veering winds to westerly and northwesterly. Due to pre-frontal WAA, maximum temperatures should be warmer than today's, with highs expected to reach the lower 70s for most of central NC.
640 PM EDT Fri Mar 21 2025 Dry and cooler conditions can be expected today, followed by rain and possible snow showers on Saturday.
610 PM CDT Fri Mar 21 2025 - Scattered rain showers will be possible along and ahead of a cold front this afternoon and evening.
513 PM CDT Fri Mar 21 2025 (Tonight) At the surface, high pressure will continue to build across the Gulf coast promoting high and dry conditions through the remainder of the day and through the night. Temps will only be able to fall into the high 30s and low 40s before sunrise as daytime heating takes over.
742 PM EDT Fri Mar 21 2025 An upper level trough will approach from the west tonight. A surface cold front will cross southeast starting with the predawn hours on Saturday and exiting the region by late morning. The cold front will produce a low probability of showers as it passes.
Expect slightly cooler temperatures and mainly rain mixing with a little bit of snow, as well as gusty winds Saturday afternoon and evening. WEATHER PATTERN OVERVIEW: The approaching low pressure trough from the west, will already begin introducing more clouds this evening, but they will only likely result in virga showers tonight until stronger forcing and more moisture arrives early Saturday morning. When we saturate the lower levels of the atmosphere, rain is expected to reach down to the surface sometime after sunrise as wind orient more from the south.
929 PM EDT Fri Mar 21 2025 A cold front will cross the area Saturday evening.
(Normal highs are in the mid 50s with normal lows near freezing). Breezy northwest winds continued across the local area this afternoon behind a cold front that pushed across the region this morning. With cooler air advecting in aloft, a few, mainly diurnally induced showers/sprinkles have popped up across the local area. As the aforementioned front tracks further east on Saturday, expect southerly flow to increase across the area with a warm front pushing in from the west, resulting in warmer temperatures and potential fire weather concerns again tomorrow.
907 PM EDT Fri Mar 21 2025 An upper level trough will approach from the west tonight. A surface cold front will cross southeast starting with the predawn hours on Saturday and exiting the region by late morning. The cold front will produce a low probability of showers as it passes.
Calm winds and clear skies due to high pressure building in overhead will lead to good radiational cooling. Overnight lows will be in the mid-upper 30s inland to the low-mid 40s along the Atlantic coast and St. As of 2 pm, latest surface analysis indicates weakening gradients and thus decreasing winds as surface ridging noses in from the west. Temperatures continue to rise and should peak in the low/mid 60s this afternoon. Temperatures are expected to fall to the lower 40s and upper 30s inland, which may lead patchy frost from the Suwannee Valley into interior areas of southeast GA. High pressure will be overhead Saturday morning. The high will center more to the east Saturday afternoon through Saturday night, as a weak cold front passes to the north northeast.
A cold front from the northwest will move through our CWA overnight followed by decreasing rain and snow showers by sunrise, but continuing in the west-central Idaho mountains due to upslope enhancement. Snow level will also lower behind the cold front to near 4000 feet MSL, but convective downdrafts may bring heavier snow showers down to valley floors in ID north of the Snake Basin.
Winds have already begun to slowly weaken as of 18z, and will continue to diminish and become more easterly through the evening hours as broad surface ridging settles over Oklahoma. The highest confidence in breezy conditions with winds of 15 to 25 mph is currently over the far SW TX Panhandle, with hi-res consensus favoring lighter winds over the remainder of our area with some locations potentially seeing winds remain under 15 mph through most of the day.
- Warmer and more humid conditions expected today and Sunday.
Higher threat for snow and a short period of freezing rain north of I-94. Expectation is for a band of north-south running pcpn ahead of cold front to become more expansive overnight, quickly shifting into eastern WI by Sun afternoon. Warm layer a loft and colder near sfc temps leans into a freezing rain potential overnight tonight. The longwave upper level trough will continue to influence the region for the start of the new week, and a perturbation or two could ripple across the area as a result. Upper level ridging starts to build in from the west as we move into the middle part of the new week, with solid support from all 4 of the WPC clusters. That said, as long as the ridge continues to slide in, above normal temps should follow.
A bulk of the wind impacts will be confined to the higher terrain, but the northern valleys will also experience breezy afternoon winds. Accumulating snowfall over the higher terrain will also result in hazardous travel at times, especially over mountain passes.
We will have low humidity again Saturday, but with high pressure present winds will be much lighter.
Following a chilly start, high pressure remains in control today with light and variable winds under sunny skies as temps rebound close to normal levels with highs in the lower to middle 70s over inland areas, while a weak sea breeze develops along the Atlantic Coast with highs around 70F at the Atlantic beaches. High pressure builds eastward into the Western Atlantic with mainly clear skies expected across SE GA, while some increase in high clouds will be possible across NE FL during the overnight hours.
The ridge axis will exit to the east this morning and winds will shift southeast and increase this afternoon as the next low pressure system approaches from the northern Rockies. Despite very low RH in Wisconsin this afternoon with RH in the upper teens to low 20s, light winds lingering from the exiting ridge axis will mitigate fire weather concerns. The center of low pressure will continue east across the Dakotas this afternoon and reach Minnesota late tonight. The lower levels will remain quite dry, but some of the steadier showers should be able to make it to the surface at times. The low will continue east to Wisconsin on Sunday and lingering wrap around showers will continue to bring precip chances.
Chcs for showers/storms wl be noted acrs Nrn AR/Srn MO late Sat night, along an advancing wrm frnt associated w/ a separate lobe of low pressure moving acrs the Srn Plains.
148 AM EDT Sat Mar 22 2025 An upper level trough will approach from the west tonight. A surface cold front will cross southeast starting with the predawn hours on Saturday and exiting the region by late morning. The cold front will produce a low probability of showers as it passes. They will also lighten in the afternoon as high pressure tracks from the western CWA in the evening to east of the CWA before daybreak. Winds will shift to the southeast after the high passes to the east.
This will bring a pair of cold fronts across the area. High pressure is forecast to build into the area tonight with relaxing surface winds and colder temperatures across the area. Low temperatures on Saturday morning will be in the mid 20s north of Highway 30 to the lower 20s in far northeast Missouri and west central Illinois. It will be slightly cooler on Saturday with high temperatures ranging from the upper 40s northwest of a Manchester to Princeton Illinois line to the lower 60s in far southeast Missouri. 90" ahead of a cold front that will quickly move west to east through the area on Sunday.
High temperatures should reach the lower to middle 60s, with the lower values still over the dwindling snow pack. A cold front will move into the region tonight, switching winds to the northwest, but also bringing a small chance of showers, although rainfall amounts are forecast to remain light at less then one tenth of an inch. Overnight lows remain above freezing only dropping to the upper 30s to lower 40s. There could be spotty lingering morning showers or sprinkles for northeast NE and northwest IA, and then highs will be cooler reaching the upper 50s to lower 60s.
By sunrise Sunday morning, a weak cold front approaches from the north and moves through the Permian Basin. From the Pecos River Valley to the south and west, temperatures stay on the much warmer side with highs in the mid to upper 80s.
Today: We finally get a break from the strong winds as high pressure sets up over the Upper Mississippi Valley into the Great Lakes. This setup will result in a small window for precipitation locally before a cold front/westerly wind shift advects in a much drier air mass for Sunday PM.
The steady southeasterly flow will continue to advect moisture and warmer air into Deep South Texas resulting warming temperatures and increasing dewpoints through the weekend. Highs today will range from the 70s at the beaches, the low to mid 80s away from the coast and the upper 80s across the Upper Valley and the Rio Grande Plains. Sunday will be warm to very warm with highs in the 80s to the lower 90s, except for 70s at the beaches.
(Today and tonight) Warmer weather will occur today as yesterday's cold front dissipates in response to lee cyclogenesis and a strengthening low-level thermal ridge to the west. , 850 mb) on the eastern periphery of the thermal ridge will allow for afternoon temperatures ranging from the mid 70s to mid 80s deg F. The highest wind gusts are expected across northwest Oklahoma.
