328 AM EDT Sat Mar 15 2025 - Storms early this morning, then warm and windy - 30 degrees colder Sunday with rain mixing with snow - Warm mid week, then colder - Storms early this morning, then warm and windy Regional radar shows a mature cyclone over Iowa with a broad band of convection stretching from northern WI to near CHI south to MEM. Another upper trough will move northeast toward Lower MI this afternoon in conjunction with a surface wave riding up the cold front. - 30 degrees colder Sunday with rain mixing with snow Once the cold front moves through tonight, colder air will flow back into the cwa.
142 AM EDT Sat Mar 15 2025 Subsidence from high pressure aloft allowed for sunny skies and warming temperatures today, with highs topping out in the low to mid 80s across much of the area. Weak high pressure will hold over the waters today, then winds will shift to southerly and increase this weekend ahead of a cold front.
Gusts between 40 to 50 mph are possible after midnight as the low level jet strengthens overhead and winds mix down to the surface. As you move E of I-65, most convection looks to outrun the low-level moisture possibly decreasing storm activity, but there still looks to be a lot of shear in place that could keep storms severe in nature going into Saturday morning.
- Unseasonably warm and windy conditions will prevail today ahead of a strong cold front. Given the rapidly moving and interacting elements along with the high level of shear, tornados are also possible. Very cold air will spread over the area behind a strong cold front tonight. It's hard to imagine snow accumulating where the high temperature yesterday was 80 degrees. A very active pattern is ahead this upcoming week as numerous short waves, upper level disturbances and upper trof transverse the CONUS.
Secondary cold front just approaching Iowa Minnesota border with area of stronger winds aloft. /rev The upper low responsible for the severe weather yesterday was stacked over northwest Iowa this morning. As this low lifts north this morning, moisture will continue to wrap around into the deformation zone and produce precipitation.
- Cooler and drier conditions will move in behind the storm system tonight into Sunday.
845 AM CDT Sat Mar 15 2025 - Rain will transition to freezing rain and then snow throughout today starting early this morning. A winter storm warning is in effect for areas expecting the highest impacts. Wind gusts 35-45 mph are expected, with the highest along the North Shore. Cold air advection is ramping up across our west where surface temperatures are around 23 in the Red River Valley and in the lower 30s for the Brainerd Lakes region. Webcams are showing a quick transition from rain/freezing rain to snow. This will lead to some freezing rain and sleet across north central Minnesota. Behind the cold front, winds will quickly increase out of the northwest, with gusts around 35 mph for most of the Northland. Wind gusts will decrease as the low exits the region throughout the morning Sunday.
348 AM MDT Sat Mar 15 2025 - Light to moderate snow showers will continue over the higher terrain today. - Windy upper trough and cold front whip through the area late Tue/early Wed, with widespread snow showers and areas of blowing snow, especially Tue night. The upper low from yesterday will continue moving off to the northeast, as a broad upper trough trails to our south. Snow showers will continue across the higher terrain today, spreading east over the mountains/plains interface this afternoon. Overnight lows will be in the 20s over the plains, with teens in the high valleys. Considered adding Crowley/Otero Counties to the highlight, as gap flow winds shoot eastward across the plains, though speeds here taper off just enough to end up short of criteria (25 mph), so will hold off on any eastward expansion for now.

7-10kft cigs will quickly diminish from W to E across Srn AR/N LA this afternoon, although additional 8-12kft cigs are expected to redevelop by mid and late afternoon from W to E across the region as the main upper trough over the Srn Plains this afternoon shifts E into the Lower MS Valley tonight. Winds will become NW and diminish to 5-10kts this evening as a weak cold front drifts SE into the region. Temperatures should fall off quickly this evening after sunset and winds will shift around to the northwest in the wake of a strong cold front.
A dangerous severe weather system trailing to the south of this low will also continue to move east and is expected to move over the Florida peninsula tomorrow afternoon/evening.
(Rest of today through Sunday) Generally benign sensible weather conditions will be felt across South Florida through the weekend, with a high chance for warmer than usual temperatures and breezy winds. Mid-level ridging will break down today as a stout trough and surface level storm system move across the southeastern US. Winds become more southerly Sunday afternoon as a cold front tailing the aforementioned storm approaches the region.
(Rest of today through Sunday) Showers and thunderstorms continue this morning as the warm front pushes northward. The limiting factor so far has been the warmer air aloft capping a lot of the convection from going severe, but with the warm front lifting northward, surface warming will continue and allow for the cap to weaken to increase the severe threat. (Sunday Night through next Saturday) Drier and cooler conditions will start the week as the deep trough over the eastern CONUS continues eastward.
Mid afternoon surface analysis had a cold front dropping south across our delta region and northeast Louisiana parishes. /22/ Through next Sunday: A ridging pattern will establish itself over the region, bringing with it a welcome calm benign weather regime for the work week.

, will move from the Lower Mississippi Valley toward the western Great Lakes. LER upper divergence and PVA aloft, combined with a corridor of increasing saturation and convergence associated with a redeveloping 700mb trough axis, will likely lead to a narrow band of wet snow across far eastern/southeast Iowa into parts of NW Illinois late tonight. The highest chances for some measurable snow are in the counties along and east of the Mississippi River (50-70%), mainly between 11 PM to 7 AM; this area has about a 30-50% for reaching 1" of snow accumulation, highest south of the Quad Cities. The warm ground will limit most of the minor accumulations of a dusting - 1" to grassy/elevated surfaces and possibly bridges/overpasses.

- Unseasonably warm and windy conditions will prevail today ahead of a strong cold front. Expect a substantial, widespread rain with embedded thunder to develop/spread in later this evening as deep layer forcing intensifies ahead of ejecting strong cyclone. Dry and moderating temps follow Mon-Tue ahead of next formidable mid latitude cyclone developing across the plains.
(This evening through Sunday) The upper level trough that brought the strong winds and continues the breezy conditions today will move off to the east tonight into Sunday, leaving our area in dry northwesterly flow aloft. Under these conditions, temperatures will warm a few degrees from today into the upper low to mid 70s, with a few readings in the upper 70s along the I-10 corridor.

657 PM CDT Sat Mar 15 2025 - Gusty winds will continue through early this evening as a strong low pressure system lifts northeast across the central CONUS.
At the same time, sharp troughing extends down the Mississippi Valley and the adjacent Gulf. For the time being, deep layered ridging remains across our area. The healthy southeasterly flow has brought in increasing moisture through the lowest levels. The Keys will remain within a fairly tight flow between a strong high to our northeast and troughing off to the northwest. Forecast sounding indicate the lower of the mentioned inversion will wash out overnight. The combination of a beefy Atlantic surface and the tail end of sharp troughing stretching down the Mississippi Valley and Gulf is generating fresh southeasterly breezes across Keys waters this evening.
Meanwhile, the main upper trof axis is just west of AR and wl cont working eastward tngt and into Sun, along with an assocd CDFNT.

Dynamic storm system continues across a broad section of the central and eastern CONUS, as a southern Stream trof over the southern Plains phases with a deep closed low over Lake Superior. The window closes as the low lifts northward across Kentucky this evening, then finally exits between 03-06Z. Unsettled wx continues on Sunday as the upper trof hangs back. Broad trough axis will run from the Great Lakes to the Gulf at the start of the period.
The upper level trough will be moving overhead this evening with some more clouds for the most part over I-30, but a few showers remain possible until sunset for areas north of I-20 and east of I-49. We can expect mostly sunny skies on Sunday that will feel great with the drier and slightly cooler highs due to the CCA, with mid to upper 60s for most of us.
Lows tonight will dip several degrees below normal once again as westerly to northwesterly flow and lingering cooler air from yesterday's weather disturbance remains across the Desert Southwest. Aside from an early week trough traversing mainly north of the region, temperatures will continue to trend warmer, with temperatures several degrees above normal by the end of this upcoming week. The mid to upper level pattern will transition from the residual troughing from the disturbance that moved through the region over the last couple of days to a Pacific ridge building into the region tonight and through tomorrow.

Dew points along the island chain measure in the lower 70s while thermometers record temperatures in the mid to upper 70s. While the lower atmosphere is very moist, satellite observations show sparse cloud cover across southern Florida. Off to the east, a 1032 mb high will keep breezes moderate to fresh, though a lull is likely this afternoon as the high moves east and the gradient weakens. Which dodges the topic of concern, a cold front attached to secondary lows from the extremely potent trough that fueled a host of blizzard, flood, severe, and tornado warnings across the United States. Relative to 4 AM, the cold front is located just west of Tallahassee with thunderstorms developing over the Gulf south of Pensacola.
Dry and warmer weather expected through Sunday as high pressure aloft builds over the region.
- Strong northwest winds gusting 20 to 25 mph will bring much cooler conditions to the region today.
312 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.
(Today and tonight) An upper level trough will shift east of the area today, with northwest winds increasing to 10 to 15 mph, with higher gusts late this morning and into the afternoon hours. Highs today will be near seasonal normals, in the low to mid 70s.
With the upper trough and its surface cold front still to our west, additional scattered showers and a few thunderstorms can be expected today, primarily this morning as those features move into the region. Clearing will take place after midnight as a long north-south ridge of high pressure drifts in from the Mississippi Valley.

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).
At the surface, high pressure across Deep South Texas today will slide eastward tonight into Monday. Finally, elevated seas along the Lower Texas Coast will result in a Moderate Risk of rip currents at the local beaches today.
- Gusty south to west winds today, strongest south of the Highway 12 corridor.
GOES-16 visible satellite imagery highlights broad anticylonic flow engulfing the Florida Keys, with an approaching band of unsettled weather stretching across the central Gulf of Mexico associated with a strong cold front that supported a severe weather outbreak yesterday across the Southeast. This will support mostly sunny skies for the balance of today, temperatures easily peaking in the lower to mid 80s, and nil rain chances. From synopsis, moderate to fresh southeasterly breezes will continue to slacken this afternoon, as a cold front progresses closer to the Florida Keys. By mid week, high pressure will build over the southern United States, allowing breezes to slacken back to gentle to moderate, until another cold front pushes through late in the week. A cold front is expected to press through the Florida Keys coastal waters overnight.
