THE STRONG UPPER LOW THAT HAS KEPT THE AREA UNDER CLOUDS AND
PRECIPITATION FOR THE LAST FEW DAYS FINALLY MOVES OFF TO THE EAST
TODAY...ALLOWING A SURFACE RIDGE TO BUILD IN AND CLEAR OFF OUR
SKIES.  SUNSHINE SHOULD HELP BOOST TEMPERATURES INTO THE UPPER 30S
AND 40S MOST LOCATIONS.  OUR NEXT WEATHER MAKER IS A SHORTWAVE AND
WARM AIR ADVECTION WING THAT MOVES ACROSS THE AREA VERY LATE TONIGHT
AND FRIDAY...BRINGING A BAND OF PRECIPITATION ACROSS MAINLY CENTRAL
AND NORTHERN MINNESOTA.  IT SHOULD DEVELOP AS SNOW...THEN SLOWLY
SWITCH TO RAIN FRIDAY MORNING AS TEMPERATURES WARM ABOVE FREEZING.
THE INCREASED CLOUD COVER SHOULD KEEP TEMPERATURES FROM DROPPING OFF
AS FAR AS THEY WILL THIS MORNING...BUT STILL DROP BELOW FREEZING
EVERYWHERE.  CLOUDS TO KEEP FRIDAY TEMPERATURES DOWN AGAIN...BUT
SHOULD STILL RISE INTO THE 40S WHERE PRECIPITATION IS EXPECTED AND
TO AROUND 50 OVER NORTHWEST WISCONSIN.
