Highs today will range in the low to mid-60s, with lows tonight dropping down into the upper-30s and low-40s. Once the ridge shifts overhead, highs on Tuesday should climb into the low to mid-70s.
(Today and tonight) A dry reinforcing cold front moving southeastward across the area this morning will bring breezy northwest winds along with cooler and much drier conditions to the region today. High pressure overhead along with dry conditions and clear skies will favor radiational cooling tonight with lows in the upper 30s to low 40s.
(This afternoon through Monday) An upper trough presently extends from the W Great Lakes to the lower MS Valley. Much cooler lows are expected tonight behind the reinforcing front, ranging from the lower 30s in the NE mountains to the mid 40s in the extreme SE.

High clouds will continue to stream across the area today, as a s/wv trough approaches from the northwest. Although mild air remains in place today, southwest winds will begin to increase in response to pressure falls from our approaching trough. By tonight, as a cold front draws closer, many areas will stay mixed, with some places lee of higher terrain actually becoming windier. By Tuesday, as the cold front sweeps across the state, this will be the windiest period.

High pressure is providing for plenty of sunshine across the area this morning after the system moved out yesterday. - Showers and possible thunder mid week, then colder with rain/snow Today and Tuesday will see partly cloudy skies and warming temperatures as high pressure zips across the state.
Breezy conditions continue this afternoon as the low pressure system and trailing cold front exits into the Atlantic and a high pressure system moves towards FL from the northern Gulf. Once the high pressure settles in this evening winds will begin to diminish.
High clouds continue to increase today ahead of an approaching trough. Southwest winds will also begin to increase later this evening in areas that remain mixed, mainly areas downwind of the higher terrain, as the trough axis approaches. Moisture remains limited given the track of the low, thus the greatest chances will mainly be along and north of the Mogollon Rim.
The trough that brought severe weather over the weekend will continue to dampen to our east maintaining NW flow through the duration of the daytime hours. This will bring in a cooler and drier airmass limiting our highs to near 60 degrees.
Highs today should top out in mid 60s in our northeastern quadrant, with slightly warmer temperatures found to our southwest topping out in the low 70s. Surface ridging will migrate across the area until mid- week, resulting in dry/quiet conditions with seasonal high/low temps areawide.
(This evening through Tuesday Night) Quiet conditions and mostly clear skies today, as upper ridging has settled over the area. Upper ridging will hang across the area tonight. Expect warmer overnight temps, with morning lows generally in the 50s areawide. Cloud cover will be on the increase starting tonight into Tuesday, as the region transitions from upper ridging to southwest flow aloft ahead of a upper trough digging across the Rockies.
A band of light rain and snow showers continues to accompany the cold front across south-central Idaho this morning. The heavier bands could produce brief periods of heavy snow, though surface temperatures in the mid to upper 30s will limit accumulations, especially on warmer surfaces in the lower valleys. The airmass will become increasingly unstable this afternoon as the upper-level trough moves over the region, triggering the development of convective showers. Surface winds: variable 5-15 kt, then NW 10-20 kt gusts 25-35 kt behind cold front this eve.

(Today through Tuesday) Low pressure is currently centered across southern VA and is moving NE along yesterday's frontal boundary. High pressure will build in from the west today. Pressure gradient at the surface will be tight during the early part of the day as the high builds in from the west and the low departs off the Delmarva Peninsula. Lighter winds are expected on Tuesday as the high pressure center currently along the Gulf Coast moves overhead. Not only will there be high pressure ridging at the surface but also in the mid levels through the remainder of the short term period.
1227 PM CDT Mon Mar 17 2025 - Dry fuels, breezy winds in the morning, and warmer temperatures will lead to high grassland fire danger today in central South Dakota. Confidence is low that the lowest RH will align with the strongest winds.
A dry northwesterly flow pattern aloft will continue through Tuesday as an upper trough pushes into the western Atlantic and upper ridging builds over the central US. The axis of this ridge moves overhead Tuesday night. At the surface, high pressure will slowly shift eastward across the Gulf Coast states, anchoring itself over the Florida Peninsula by Tuesday night. With subsidence in place from the ridging aloft and at the surface, along with PWATs less than a half inch, no rain is expected through Tuesday night.
The 12z RAOB was also bone dry from just off the deck all the way up to the tropopause leading to a PWAT value of one of the lowest we will see around here at 0. A warming trend begins tomorrow as upper level heights begin to rise with subtle ridging and a surface return flow developing on the backside of the departing high pressure. It will take a bit of time for the low level moisture to increase, but gradually tomorrow doesn't look quite as dry as today with relative humidity values in the 30 to 40 percent range during the afternoon unlike the 20-30 percent range today.
221 PM CDT Mon Mar 17 2025 - Cold front will move southeastward across the area Tuesday.

Winds become a little more southwest on TUesday and despite some climb in surface dewpoints, warmer temperatures will again produce fire weather concerns. (Tuesday night through next Monday) A more ridge like pattern will keep warm temperatures in place across the region through Tuesday night. However, a fairly strong low pressure aloft will drift through the Panhandle of Texas. This low pressure will be strong enough to drag a pretty strong cold front through our area.
A deep mid-level longwave trough was over the Eastern portion of the Country while broad ridging was over much of the South- Central Plains. High temperatures will range from the upper 50s in the higher terrain east and northeast to readings in the upper 60s far southwest. Broad mid-level ridging will become positioned over much of the Southern and Central Plains tonight. Low temperatures will range from the lower 30s in the normally colder valley locations northeast to around 40 southwest.

Lusk (Today through Tuesday) Low pressure is currently centered across southern VA and is moving NE along yesterday's frontal boundary. High pressure will build in from the west today. Pressure gradient at the surface will be tight during the early part of the day as the high builds in from the west and the low departs off the Delmarva Peninsula. Lighter winds are expected on Tuesday as the high pressure center currently along the Gulf Coast moves overhead. Not only will there be high pressure ridging at the surface but also in the mid levels through the remainder of the short term period.
Clearing skies and lighter winds will set the stage for effective radiational cooling across South Florida with forecasted low temperatures in the mid to upper 40s across inland southwestern Florida, upper 40s to near 50 along the gulf coast and east coast suburbs, and temperatures in the low to mid 50s along the immediate east coast. A few locales in Southwest Florida could drop into the lower 40s if winds decouple. This subtle wind shift will keep high temperatures cooler along the immediate east coast. The warmest forecast high temperatures will be across southern Collier and Mainland Monroe counties with highs in the lower 80s.

It could be one of those scenarios where there are large differences in snow amounts between eastern Rapid City and western portions in the higher terrain.
Highs this afternoon look to remain mild along with some slightly breezier southwesterly winds, especially downwind of the high terrain. High clouds will continue to stream across the area today, as a s/wv trough approaches from the northwest. Although mild air remains in place today, southwest winds will begin to increase in response to pressure falls from our approaching trough. By tonight, as a cold front draws closer, many areas will stay mixed, with some places lee of higher terrain actually becoming windier. By Tuesday, as the cold front sweeps across the state, this will be the windiest period. Wind is not the only story with this trough, as the cold front will be strong enough to generate some rain and snow showers.
Upper ridging will remain over the region today, yielding mostly clear skies and low humidities. Otherwise, upper-level ridge to the west will maintain northwest flow aloft today allowing for mostly clear skies.
