Much cooler air will move in behind the front overnight, dropping lows into the upper 30s. Outside of the light precip, Thursday will blustery, cloudy, and cool with afternoon highs in the 40s - nearly 20 to 25 degrees cooler than today. (Thursday Night through next Wednesday) Temperatures will drop below freezing for everyone Thursday night as skies clear and winds calm.
(This evening through Thursday Night) Cooler and drier conditions will continue to move into the area this afternoon and through tomorrow in wake of a cold front. But, some wrap around clouds from the closed trough associated with the aforementioned cold front could move into areas north of Interstate 30 tonight and early Thursday morning. Northwesterly flow will yield much cooler temps on Thursday afternoon, with highs in the 60s.
The trough will bring minimal rain and snow to southern areas overnight and early Thursday morning, but.
352 PM CDT Wed Mar 19 2025 Tonight and Thursday: Mid afternoon water vapor imagery/RAP analysis showed the circulation around a closed low spinning over northern Missouri. This closed low was supporting an associated <1000mb low that had a trailing cold front just to the west of our CWA. The drier air wrapping around the closed low was essentially limiting the moisture pooling over our region ahead of the approaching cold front.
Breaks in the morning stratus was showing up on satellite imagery and already allowing temperatures to warm into the lower 70s. A gusty south-southwest wind was noted increasing across the CWA ahead of an approaching cold front. Although moisture and warmer than normal temperatures are expected today, instability looks to remain rather limited ahead of the approaching cold front. A few showers are expected this afternoon but by this evening a few isolated strong to severe may occur over our northeast zones before the cold front shifts into Alabama. A strong cold front will reach western portions of the forecast area this afternoon, and then move quickly across the area as we go into the evening.
238 PM MDT Wed Mar 19 2025 - Warmer and drier by Thursday, with near critical to critical fire weather conditions across southwestern and south central SD - Increasing chances for precipitation and breezy/gusty northwest winds late this week and over the weekend Water vapor imagery shows upper ridging quickly building across the region behind the ongoing Midwest blizzard. The upper ridge will continue to build into the region tonight into Thursday, bringing strong warm air advection. A thermal ridge will cross the region Thursday afternoon, bringing highs in the 50s and 60s across the western SD plains.
1245 PM CDT Wed Mar 19 2025 Breaks in the morning stratus was showing up on satellite imagery and already allowing temperatures to warm into the lower 70s. A gusty south-southwest wind was noted increasing across the CWA ahead of an approaching cold front. Although moisture and warmer than normal temperatures are expected today, instability looks to remain rather limited ahead of the approaching cold front.

A strong cold front will reach western portions of the forecast area this afternoon, and then move quickly across the area as we go into the evening.
Satellite image shows the cold front still offshore. Stronger winds are being observed over the higher terrain along the coastal mountains in southwest Oregon. Guidance suggest sustained winds will be in the high gale range with storm force gusts for about a 3-6 hour period late this morning and afternoon.
Short term model blends have overnight lows in the low to mid 30s and that seems appropriate, although it may take right until sunrise to see temperatures hit those forecasted readings.
- Lighter winds and cooler temperatures result in lowered fire weather potential for Thursday Looking at visible satellite this afternoon most areas are fairly cloudless with a patch of blowing dust moving into the CWA from the northwest. These strong northwesterly winds should subside after sunset and really start to decrease after midnight tonight as high pressure slides over the area. Temperatures rebound slightly with most areas seeing highs in the low to mid 70s areawide. Fire weather concerns should also be minimal due to the lower temperatures and lighter winds, however RH values will still be quite low (10-20%). Thursday night could be another chilly evening however, lows look to be slightly warmer with most locations staying in the 40s.
Impressively dynamic cyclone was over SW KS at midnight, with surface observations showing the strong 986 mb surface cyclone near Great Bend at 1 am. The midlevel cyclone will continue to intensify as it crosses Kansas this morning, with a 538 dm low near Salina at 7 am. Rapid improvements Thursday, courtesy of broad ridging quickly expanding over the plains, and the return of SWly downslope winds of 15-25 mph.
If the system can get updrafts going along/ahead of the approaching cold front, given the high shear environ. Once the cooler/drier air completes its overtake of the column, we'll finish out the week with a dry/seasonally chilly feel.
Breezy northwesterly winds following the preliminary cold front this morning will continue through this evening as a secondary front pushes south through the FA around sunrise. Following the passage of both cold fronts, low temperatures tonight will be at or below freezing however, highs tomorrow will warm to around or just below seasonal average.
There will be a period of less intense winds this evening behind the storms, before the deep upper trough behind the departing low arrives. Overnight snow threat: As the aforementioned upper trough moves in, another round of precipitation arrives.
149 PM EDT Wed Mar 19 2025 (Today and tonight) Breezy onshore flow is expected today as the next cold front pushes eastward across the Gulf Coast states.
High pressure moving across the southeast U. The aforementioned high pressure will meander into the southwest Atlantic this evening into Thursday as the next weather system barrels out of the Central Plains and into the Great Lakes.
After a day of sunny skies and mainly light winds will feel the effects of a fast moving Pacific system tonight through Thursday as the upper level ridge slides east tonight.
1232 PM EDT Wed Mar 19 2025 Quiet conditions are expected today as high pressure remains overhead. Otherwise, look for a weak cold front to push eastward across the region Thursday, causing showers and breezy winds to return to the forecast. High pressure then returns heading into the weekend. Given mild llvl thicknesses, afternoon temperatures should peak around 80 degrees across the SC Lowcountry to the low to mid 80s across SE GA. Lows are expected to be in the low to mid 50s. Thursday: Rain chances return across the region Thursday ahead of an advancing cold front. Moisture with this boundary also remains limited, keeping QPF totals between a few hundredths to perhaps a tenth or two - with the highest amounts currently focused northeast of I-26. Currently have gusts rising into the lower 20s, with Lake Moultrie approaching 25 MPH.
(The rest of this afternoon and tonight) Noticeably cooler conditions are in place across much of the area this afternoon in the wake of the cold front that edged through earlier today. Strong winds continue in the wake of the cold front from the west-northwest this afternoon. (Thursday through Wednesday) Calmer conditions are expected on Thursday as high pressure builds into the region.
996 mb low pressure was analyzed over northwest Indiana early this evening, with the upper level low farther west over west central IL. Tightening MSLP gradient on the back side of the low will produce wind gusts near 45 mph, which can produce sharply reduced visibility in areas of snow. There will be a period of less intense winds this evening behind the storms, before the deep upper trough behind the departing low arrives. Overnight snow threat: As the aforementioned upper trough moves in, another round of precipitation arrives.
901 PM CDT Wed Mar 19 2025 At this point, the cold front has now cleared east of our Four State region with NW winds on the backside of the front still quite gusty - which is why the area Wind Advisory remains in effect for the entire area until 10 PM CDT. This is to say the wildfire danger will slowly wane through the night with cooler temperatures moving in. /50/\ (This evening through Thursday Night) Cooler and drier conditions will continue to move into the area this afternoon and through tomorrow in wake of a cold front. But, some wrap around clouds from the closed trough associated with the aforementioned cold front could move into areas north of Interstate 30 tonight and early Thursday morning. Northwesterly flow will yield much cooler temps on Thursday afternoon, with highs in the 60s.

A thermal ridge will cross the region Thursday afternoon, bringing highs in the 50s and 60s across the western SD plains. As cooler air moves in, precip could change to snow before ending, but again it looks like little to no accumulation.
Winds on the backside of the low continue to be strong with 850 mb winds 40-60 kts through southwest Kansas and a tightly packed surface pressure gradient leading to sustained surface winds at 30 mph and gusts to 50 mph. Conditions should continue to improve tonight as the snow will have long ended and as the upper low moves to the east we should see winds gradually diminish through the overnight and settle to around 5-15 mph by sunrise Thursday morning. This will bring in a cold front with little moisture so precipitation is not anticipated.
Radar shows scattered showers in bands moving east, just ahead of a the approach of a strong cold front. Upper level trough axis to be positioned east of the MS River Valley by daybreak moves east to across the Appalachians tonight. A cold front will have moved through the area, bringing drier and cooler air in its wake today with highs ranging 57 to 62 interior to mid 60's coast. The center of the high slips southeast over the eastern Gulf and the FL Peninsula Friday with highs in the mid to upper 60's.
High pressure and quiet weather move in to finish the weekend and temperatures rise to near or record heat by mid week. High temperatures will be about ten degrees below normal, with a few showers possible along the Oregon/Idaho border (PoPs <25%) due to a weak upper trough passing to our north.
The bigger impact from this system in the lower elevations will be from the wind and a Wind Advisory remains in effect across the Snake Plain and into the Arco Desert. Temperatures the next couple of day will be on the cooler side of normal but this will change drastically over the days ahead.
