As a strong area of low pressure departs the region today, high pressure will build in its wake. Highs will range from the lower 50s across the northwest to the lower 60s across the southeast big bend.

Low level thermal ridging and downslope flow will allow temperatures to climb to much above normal Wednesday afternoon. Large upper level trough moving across the mid section of the country will drop a cold front south into the forecast area Wednesday night. Low level convergence along the front with some forcing from the upper trough could spark isolated showers and thunderstorms across the extreme eastern Permian Basin in the deeper moisture.

FAVORED THE WARMER MAV TEMPS FOR TODAY. ASSOCIATED COLD FRONT WILL MOVE THROUGH THE REGION THURSDAY MORNING.
ABOVE FREEZING TEMPERATURES AT 850MB OVER THE FOX VALLEY AND LAKE SHORE WAS RESULTING IN A MIXTURE OF SNOW. SLEET AND FREEZING RAIN. MODIFIED PACIFIC AIR WILL MOVE INTO THE AREA THIS AFTERNOON ON GUSTY WEST WINDS ALLOWING TEMPERATURES TO RISE ABOVE FREEZING AND SOME MELTING TO OCCUR.
Snow showers linger in western Montana early this morning as yesterday's trough exits the region. The warm frontal nature of the upcoming weather system is going to lead to rising snow levels today and tonight so any impact from mountain snow looks to be minimal to non-existent.
A WEAK TROUGH WILL EXTEND SOUTHWARD AND MOVE ACROSS THE MID STATE THIS AFTERNOON.
Thursday through the weekend will be much warmer than average with afternoon temperatures in the 60s.

STRENGTHENING HIGH PRESSURE WILL ELIMINATE EVEN THIS SLIGHT CHANCE FOR THE SECOND HALF OF THIS PERIOD WITH NEARLY CLEAR SKIES AND NEAR ZERO PROBABILITY OF PRECIPITATION. THE WARMER AIR MASS UNDER THE RIDGE WILL MEAN STRONG WARMING IN THE AVAILABLE SUNSHINE.

Sunshine and a warming airmass return to NorCal today in response to building high pressure and developing offshore (northerly) flow. Despite the increase in winds, much of the northern half of the valley is seeing cooler temperatures early this morning as skies have finally cleared.
429 AM EDT WED MAR 25 2015 MOISTURE ACCOMPANYING LOW PRESSURE TO THE NORTHWEST WILL BRING WIDESPREAD SHOWERS AND SCATTERED THUNDERSTORMS TODAY. A COLD FRONT CONTAINING COPIOUS MOISTURE WILL PRODUCE ADDITIONAL SHOWERS AND THUNDERSTORMS LATE TONIGHT THROUGH THURSDAY.
HIGH PRESSURE WILL BUILD INTO THE GREAT BASIN THROUGH THE REMAINDER OF THE WEEK. THE AXIS OF THE UPPER TROF THAT BROUGHT PRECIP TO THE CWA YESTERDAY AND OVERNIGHT IS ACROSS ERN UT EARLY THIS MORNING AND WILL EXIT THE CWA SHORTLY. A COOL DRY SUBSIDENT NORTHERLY FLOW FOLLOWS THIS TROF AND WILL KEEP BREEZY NORTH WINDS GOING ACROSS MOST OF THE AREA TODAY WHILE TEMPS WILL ONLY MANAGE TO REACH NEAR NORMAL VALUES.

HIGH PRESSURE CONTINUES ALONG EAST COAST WITH LOW PRESSURE NEAR CHICAGO.
UPPER LEVEL RIDGE SHOULD BUILD OVER THE PAC COAST AS THE TROUGH DEEPENS OVER THE GREAT LAKES AND MISS RIVER VALLEY. THIS MEANS THAT TEMPS MAY BE A TOUCH COOLER THAN PREVIOUS FORECASTS GIVEN THE STRONG COLD ADVECTION. YESTERDAY THE GFS/ECMWF SOLUTIONS HAD BEEN SHOWING A RATHER POTENT UPPER LEVEL TROUGH MOVING ACROSS THE AREA NEXT TUE/WED.
