1130 PM CDT Sun Mar 26 2023 A weak upper level disturbance will move across the Lower Mississippi Valley tonight. This will result in isolated to scattered showers and thunderstorms across portions of North Mississippi and West Tennessee near the Tennessee River this evening, then come to an end overnight as high pressure builds back in across the region.
As cool and dry air continues to advect into the lower atmosphere, expect another chilly morning. Lows will range from the lower 30s in the north to low 40s in the south.
Northern stream trough passes through North Dakota tonight. Looks like any snow associated with that trough will remain north of the forecast area.
1116 PM EDT Sun Mar 26 2023 Dry weather continues through this evening with departing high pressure. Rain returns Monday with crossing low pressure. Cloudiness coming up the Ohio Valley in advance of trough now over Chicago area will spread into forecast area later tonight. Rain during the daylight hours may mix with or change to snow as the system departs Monday night as cooler air filters in, but no significant accumulation is forecast. This system will be even less impressive in terms of moisture, with PWATs below a half-inch and Great Lakes high pressure helping to provide a dry push. Thus, low PoPs are indicated, although these will be slightly higher in the ridge zones with modest upslope influence.
308 AM CDT Mon Mar 27 2023 A cold front has made passage through the entire area with a breezy north wind in place.
Cooler on Monday and Tuesday, followed by a warming trend through mid to late week.
1146 PM CDT Sun Mar 26 2023 (This evening through Monday Night) Some lingering showers (maybe an isolated thunderstorm or two?) are anticipated early this evening near and along a weak convergence boundary and slowly southward sagging cold front. Inland highs will be in the low to mid 80s. The rain chances will actually increase heading on into the evening and especially the overnight hours Monday night with showers and thunderstorms forming along and ahead of the next cold front. Highest rainfall amounts look like they might end up setting up generally along the I-10 corridor with the higher numbers the further east you go toward the TX-LA border.
(Today through Tuesday Night ) A cold front is dropping SE through the state early this Mon morning. Another surge of drier cooler air will move into the state on Tue behind this upper wave. with highs a few deg cooler as a result. Temps Tue night will drop down into the low to mid 30s across the north.
Skies clearing quickly in the wake of this feature, while cold front has basically moved southeast of the area.
(Today and tonight) An upper level short wave trough will move from eastern Wyoming/central Colorado at sunrise today to western Kansas/Nebraska at sunset and the Missouri Valley by sunrise Tuesday. Once the upper trough moves onto the High Plains early this evening, another cold front will race southward, likely clearing the forecast area by midnight with north winds becoming gusty and brisk.
This front will migrate southward through the forecast area overnight bringing increasing clouds area-wide and some mainly light showers over the higher terrain of the forecast area.
High pressure continues to be locked in across South Florida in the short term. A cold front moving across the southeast will stall well north of the region with the active weather remaining well north. The above normal and warm temperatures will continue with maximum temperatures in the mid to upper 80s and reaching into the lower 90s over the interior. Low temperatures will range from the mid 60s inland to the low to mid 70s along the coasts.
132 AM EDT Mon Mar 27 2023 A cold front continues to move farther east into the area bringing cooler and drier air, but showers will linger out in front of it south of US-24 this morning.
With high pressure building from the northwest, the belief is that sufficient mixing and drier air across the region by daybreak will eliminate any fog concerns thereafter. Conditions forecast to improve from the west on Tuesday as weak upper-ridging builds across the area.
Winter storm warnings/advisories will expire at midnight with accumulating snowfall ending, however roads will remain icy across parts of southwest MT as wet/slushy surfaces are re-freezing this evening. 1140 PM MDT Sun Mar 26 2023 (27/06Z TAF Period) The low pressure system responsible for the snow over Central and Southwest Montana will continue away form the region for improved conditions; however, there will be an abundance clouds and patchy fog/light snow that may degrade conditions to MVFR or even some IFR. Additional improvement is expected Monday morning across central and southwest MT while a weak cold front maintains low clouds along the Canadian border. These clouds are expected expand deeper into the plains after 28/00Z as the cold front slow moves southward. An upper level trough will continue to push through the region through the day today.
418 AM EDT Mon Mar 27 2023 Low pressure will bring increasing clouds and a chilly rain to the region later today with some light snow across higher elevations north of I-80. Drier and cooler conditions move in for Tuesday and last through midweek.
1225 AM CDT Mon Mar 27 2023 (This evening through Monday) This afternoon, a weak cold front is just south of San Angelo. A mid level trough will be to our northwest on Monday. Models are showing some capping in the low to mid levels, but if the cap erodes enough or parcels are lifted above the cap, we could see a few thunderstorms Monday afternoon and evening.
Early morning satellite images show cirrus streaming in ahead of an upper trough moving in from the northwest and low level stratus sinking in from the north. Weak northerly winds, mid level clouds, and subsidence amidst cold air advection aloft means another cooler than normal day across the region.
536 AM MDT Mon Mar 27 2023 Water vapor satellite imagery showing an upper level trough centered over Utah with good lift ahead of it over northern Colorado. The trough will progress eastward across the state today and be east of Colorado this evening. Mountain top observations and 700mb winds on the RAP model indicate the 700mb low/trough is over Summit and Grand Counties at this time.
656 AM CDT Mon Mar 27 2023 Today through tonight: Strong westerlies across the southern CONUS continue to support a disturbed weather pattern for the forecast area as we near the end of March, but for the short term at least, we're expecting to see a reprieve over most of the area as much drier air moves in following a weak cold front passage. The exception will be over the lower Pine Belt region including Hattiesburg where a stalling front may be close enough in proximity to support continued isolated shower and thunderstorms. Late tonight, an approaching minor perturbation will initiate deep convective development near the front, and strong deep layer shear combined with fairly steep mid level lapse rates will support organized storms that may impact locations mainly south of the Highway 84 corridor prior to daybreak Tuesday.
A slight shift in the forecast tomorrow as a cold front approaches.
628 AM CDT Mon Mar 27 2023 Cloud cover continues to increase this morning ahead of a cold front.
Water vapor satellite imagery showing an upper level trough centered over Utah with good lift ahead of it over northern Colorado. The trough will progress eastward across the state today and be east of Colorado this evening. Mountain top observations and 700mb winds on the RAP model indicate the 700mb low/trough is over Summit and Grand Counties at this time.
Small chances for snow showers or flurries will affect the area today through Tuesday as a weak cold front, and a weak short wave move across the area.
If it were not for collapsing steering flow, these showers likely would have been able to survive the trek to portions of the Lower Keys. GOES-16 visible satellite imagery is detecting mostly cloudy skies in the vicinity of the Lower Keys, with mostly sunny skies in the Middle and Upper Keys. A broken cluster of showers over the western Straits of Florida out to 20 nm south of the Lower Keys will continue to weaken over the next several hours. High pressure will continue to slide east into the western north Atlantic this afternoon and Tuesday, as a frontal boundary approaches the Florida Peninsula, stalls, and weakens.
The cold front which sparked a couple thunderstorms across our eastern CWA yesterday afternoon has well cleared our area, with WPC's surface analysis depicting it near and along the Appalachians at this time. In the wake of the front, stratus has poured into the area generally southeast of I-55 amidst cool northerly flow which has resulted in temperatures from the low 30s in Galesburg to the mid 40s in Lawrenceville.
559 AM CDT Mon Mar 27 2023 (Today and tonight) A high amplitude s/wv trough will move from the central Rockies into the central Plains today. As cold temperatures aloft approach late in the day, in combination with southward progression of surface cold front, scattered showers and even an isolated thunderstorm may skirt far northern Oklahoma. For tonight, with the passage of the cold front, northerly winds will be fairly brisk. Temperatures will not be drastically colder behind the front, but with the northerly wind, wind chill values late tonight and on Tuesday morning will range from the teens across northern Oklahoma, to the lower/mid 30s across southeast Oklahoma.
(Rest of Today) A cold front has pushed through the area this morning, and dewpoints have begun to noticeably drop as high pressure begins to push south. Skies will clear today with the drier air pushing in, allowing afternoon highs to rise into the lower 70s despite northerly flow.
High pressure moves into the northern plains following the clipper system and slides slowly east through midweek.
A dry cold front is moving through the Midsouth early this morning with high pressure building across the region in its wake. As a result cooler and dry conditions are in store for the next several days.
Onshore flow will return and strengthen for Tuesday and Tuesday night as a cold low pressure system approaches from the northwest.
Inland, temperatures are forecast to rise into the lower 90s. Winds will shift SW/W on Tue, as a weak cold front approaches the local area.
528 AM EDT Mon Mar 27 2023 Low pressure will bring increasing clouds and a chilly rain to the region later today with some light snow across higher elevations north of I-80. Drier and cooler conditions move in for Tuesday and last through midweek.
553 AM MDT Mon Mar 27 2023 The persistent trough and low pressure is finally starting to shift to the east of the area. Impacts would be limited as well as most would melt on paved surfaces with the high sun angle.
535 AM CDT Mon Mar 27 2023 (Today through Tuesday Night ) A cold front is dropping SE through the state early this Mon morning. Another surge of drier cooler air will move into the state on Tue behind this upper wave. with highs a few deg cooler as a result. Temps Tue night will drop down into the low to mid 30s across the north.
Ensemble guidance and model clusters have a good handle on the initial track of the upcoming low pressure system along the west coast of California. There has been model consistency for a low to split from the parent low pressure system and move in north- central Idaho and western Montana during the middle of the week.
328 AM MDT Mon Mar 27 2023 Water vapor satellite imagery showing an upper level trough centered over Utah with good lift ahead of it over northern Colorado. The trough will progress eastward across the state today and be east of Colorado this evening. Mountain top observations and 700mb winds on the RAP model indicate the 700mb low/trough is over Summit and Grand Counties at this time.
A cold front has made passage through the entire area with a breezy north wind in place.
611 AM CDT Mon Mar 27 2023 (Today and tonight) An upper level short wave trough will move from eastern Wyoming/central Colorado at sunrise today to western Kansas/Nebraska at sunset and the Missouri Valley by sunrise Tuesday. Once the upper trough moves onto the High Plains early this evening, another cold front will race southward, likely clearing the forecast area by midnight with north winds becoming gusty and brisk.
A low pressure system will exit the area this morning, as high pressure brings a temporary drying trend through Tuesday night.
Stubborn, lingering light snow from the Snake Plain down into the srn highlands will continue to trend south and diminish this AM with generally an inch or less of additional accumulation (but watch for slick spots!), leaving just some patchy freezing fog and increasing sunshine in it's wake.
555 AM EDT Mon Mar 27 2023 Wide array of morning observations with a mix of VFR to LIFR as low pressure system moves east across northern Ohio and slows. Expect a rather rapid clearing of low cloud this evening followed by a fairly cohesive model signal for a period of SKC tonight as high pressure builds into the Great Lakes with modest north-northeast gradient flow into Tuesday. Resident thermal profile proving much warmer than suggested by model consensus early this morning. Dry and stable conditions mark the Tuesday period, as high pressure takes control beneath weak mid level troughing.
629 AM CDT Mon Mar 27 2023 A dry cold front is moving through the Midsouth early this morning with high pressure building across the region in its wake. As a result cooler and dry conditions are in store for the next several days.
647 AM EDT Mon Mar 27 2023 Areas of rain are likely today with crossing low pressure.
540 AM EDT Mon Mar 27 2023 Areas of rain are likely today with crossing low pressure.
328 PM EDT Mon Mar 27 2023 Low pressure and widespread rain has shifted off to the east but clouds will hang on overnight. High pressure then takes over at mid week and the region dries out before the next larger disturbance begins to impact the area for the end of the week. High temperatures to range from the mid 40s north to the lower 50s south.
1200 PM EDT Mon Mar 27 2023 Low pressure will bring increasing clouds and a chilly rain to the region later today with some light snow across higher elevations north of I-80. Drier and cooler conditions move in for Tuesday and last through midweek.
Moving into the overnight hours, a cold front moving in from northern MN/southern ON brings snow showers across the area. As for snowfall amounts, most places in the west and north central should only see an inch or less tonight; however, there could locally be up to 2 inches in the higher elevations of the Porkies and along the spine of the Keweenaw, as moderate snowfall rates could be seen at times in some of the snow showers across the UP. EPS and GEFS ensemble means are especially highlighting the highlands of Baraga and Marquette Counties as well as western counties/Keweenaw.
Will maintain some degree of cigs into evening before clearing skies out as high pressure builds into the region. Resident thermal profile proving much warmer than suggested by model consensus early this morning. Dry and stable conditions mark the Tuesday period, as high pressure takes control beneath weak mid level troughing.
(Rest of today through Tuesday) Surface and upper level high pressure remain in control today across South FL. On Tuesday a cold front associated with a system moving off the Mid- Atlantic coast will slowly crawl through the SE states. Some additional diurnally driven scattered showers and isolated thunderstorms are possible during the afternoon and early evening hours, with the highest chances around the lake and the Broward/Palm Beach metros.
Expect mostly sunny skies and cooler than average temps today. Warm/moist advection occurring from TX to southern AR in advance of the wave and reinforcing surface cold front may bring a shower to far SE OK this evening, but most folks likely stay dry.
1223 PM CDT Mon Mar 27 2023 (Today and tonight) An upper level short wave trough will move from eastern Wyoming/central Colorado at sunrise today to western Kansas/Nebraska at sunset and the Missouri Valley by sunrise Tuesday. Once the upper trough moves onto the High Plains early this evening, another cold front will race southward, likely clearing the forecast area by midnight with north winds becoming gusty and brisk.
Precipitation in the lower valleys and deserts expected to be minimal.
The low/mid-level WAA zone out ahead of this Tuesday clipper system will shift low level winds around to the southwest late tonight into the first half of Tuesday.
245 PM EDT Mon Mar 27 2023 Tonight and tomorrow morning will feature quieter weather, but a wave of low pressure will bring a chance of showers by tomorrow evening.
340 PM CDT Mon Mar 27 2023 Cold frontal passage this morning has a fresh dusting in the southern Valley, with breezy north-northwest winds in its wake. With pavement temperatures currently above freezing with air temps below freezing, this is creating some blow ice as drifting snow melts on contact with warm pavement temps then refreezes. There is some signal of transient fgen associated with the low level WAA/isentropic ascent.
High temperatures on Tuesday will be much cooler with readings a few degrees below normal. Slight chance to a chance of showers later Tuesday primarily north of the Southern Valley and Plateau, with the best chance for the higher elevations. As a result, a weak low pressure center will develop east of Tennessee, bringing the return of cloud cover and chances of light rain. Following the passage of the cold front earlier today, overnight lows and highs tomorrow will be running a lot cooler, even a few degrees below normal for the end of March.
1231 PM CDT Mon Mar 27 2023 (Today and tonight) A high amplitude s/wv trough will move from the central Rockies into the central Plains today. As cold temperatures aloft approach late in the day, in combination with southward progression of surface cold front, scattered showers and even an isolated thunderstorm may skirt far northern Oklahoma. For tonight, with the passage of the cold front, northerly winds will be fairly brisk. Temperatures will not be drastically colder behind the front, but with the northerly wind, wind chill values late tonight and on Tuesday morning will range from the teens across northern Oklahoma, to the lower/mid 30s across southeast Oklahoma.
251 PM MDT Mon Mar 27 2023 Most of the excitement regarding this current storm system will be over by this evening, No changes regarding the highlights as the high res models generally show the snow ending around 6 pm. I will let the Winter Storm Warnings for northeast Weld and Morgan counties expire at 3 pm, but continue the rest of the highlights through 6 pm. It will be quiet tonight and Tuesday as a ridge of high pressure build over the central Rockies. Tuesday will be dry and warmer, but still around 10 degrees below seasonal normals.
A weak upper level disturbance will move across the Lower Mississippi Valley tonight bringing a slight chance of rain showers to East Arkansas later tonight.
Otherwise, energy moving through the cyclonic flow will push a back door cold front into the NE zones overnight with a 20-30% chance of snow for areas from NE Musselshell County ESE through KMLS and KBHK.
244 PM CDT Mon Mar 27 2023 Mostly clear skies were found across the area today as high pressure moved into the area. Cooler temps, in the 40s, were found across the area. Cooler temps continue into tomorrow.
Light snow will spread into southwest Idaho late tonight as a warm front moves from south to north across the region.
(This evening through Tuesday) A short wave trough will depart the region tonight but dramatic changes will come with this for at least a day. The dryline currently cutting across the South Plains will quickly be overtaken by a strong cold front during the evening and overnight hours.
A subtle wave in southern stream may result in a few light showers near the Red River tonight, otherwise dry with chilly overnight lows, potentially below freezing in areas near the OK/KS border.
258 PM EDT Mon Mar 27 2023 Low pressure at the surface will continue to drift east off the Mid- Atlantic Coast this afternoon. Afternoon highs will be in the low to mid 50s for most.
Mostly clear skies were seen across our region early this morning, as the area of low pressure that brought light accumulating snow to the northern portions of the area continues to track off to the east. High pressure was building in from the northwest. The system that brought snowfall yesterday across our north will continue to move off to the east, with high pressure building in from the northwest.
The cold front is draped somewhere along the Cumberland Plateau and will continue to move across the area. Greatest chance for seeing showers today will be the higher elevations of East Tennessee, SW Virginia and SW North Carolina. Expect temperatures to run a touch cooler today than yesterday. Skies clear this afternoon as drier air moves in behind the cold front.
114 PM CDT Mon Mar 27 2023 Cold front has pushed through our area per surface observations. Increased daytime temps, with warmest in the forested areas of MN nearing or exceeding the freezing mark. Outside of the MN forests, temps will likely stay below freezing. Light snow is leaving a dusting of snow for locations near I-94 corridor as upper energy interacts with cold front pushing through the tri-state area this morning. This may cause temps to touch a little higher than forecast given late March sun angle, but still lower than average and likely below freezing, at least in the Valley. Cloud cover continues to increase this morning ahead of a cold front.
Cooler conditions will ensue behind this front as highs look to be in the 60s for tomorrow as this front and the redeveloped cloud cover will keep us a bit cooler.
Winter Storm Warning is in effect for the Redding Metro as several inches of snow are likely, particularly in the hills/ridges surrounding the city.
Surface moisture boundary (feel free to call it a cold front, if you like) remains draped across the middle of Alabama this afternoon, and is forecast to sag slowly southward tonight.
A slight shift in the pattern tomorrow as a weakening cold front moves southeast over the peninsula.
112 PM CDT Mon Mar 27 2023 (Rest of Today) A cold front has pushed through the area this morning, and dewpoints have begun to noticeably drop as high pressure begins to push south. Skies will clear today with the drier air pushing in, allowing afternoon highs to rise into the lower 70s despite northerly flow.
(Tonight through Tuesday night) A cold front is stalling across our CWA stretching from near Victoria to Del Rio and then off to the northwest.
1214 PM CDT Mon Mar 27 2023 GOES-16 Satellite trends this morning depict an upper level low over the Rockies, and broad southwest flow aloft across the Lower Mississippi Valley, Southeast United States, and the Mid-Atlantic States. Surface analysis late this morning places a cold front from East Tennessee Back through Northern Alabama and across Southern Mississippi, Alabama, and Texas. CJC A dry cold front is moving through the Midsouth early this morning with high pressure building across the region in its wake. As a result cooler and dry conditions are in store for the next several days.
306 PM EDT Mon Mar 27 2023 A cold front will move through with only minor rain chances Tuesday.
A large upper level closed low off the Oregon and Washington coasts will slide down the western U. In response, a weak ridge will pop up over the Northern Rockies, however, some moisture from the California low will move through this ridge and produce a few showers across southwest Montana and Lemhi county.
