NEAR TERM THROUGH THIS AFTERNOON...COLD FRONT SLIDES THROUGH
EARLY THIS MORNING. ANY THUNDER HAS ALREADY EXITED, BUT COULD
STILL SEE A FEW LINGERING LIGHT SHOWERS BEFORE DAYBREAK ACROSS
CENTRAL AND NORTH-CENTRAL WI. MOSTLY CLOUDY SKIES THIS MORNING,
BUT EXPECT POCKETS OF CLEARING TO DEVELOP THIS AFTERNOON. DON'T
THINK IT TURNS COMPLETELY SUNNY THOUGH. BREEZY BEHIND THE FRONT,

MORNING. TEMPERATURES TODAY WILL BE AROUND NORMAL WITH MID 50S

THE REST OF THE WEEK.
MAINLY DRY REST OF THE WEEK INTO THE WEEKEND...OTHER THAN A SMALL
CHANCE OF SHOWERS WEDNESDAY AFTERNOON ON TAIL END OF NORTHERN STREAM
SHORTWAVE, AND ON THURSDAY AS ANOTHER WEAK WAVE TRAVERSES THE REGION,
HIGH PRESSURE WILL RESULT IN DRY WEATHER INTO THE WEEKEND. TOTAL
RAINFALL FROM BOTH CHANCES FOR RAIN WILL BE WELL UNDER 0.25 INCH.
NO THUNDER IS EXPECTED.
TEMPERATURES TRENDING COOLER THAN NORMAL...FROM WEDNESDAY THROUGH
SATURDAY, EXPECT BELOW NORMAL TEMPERATURES. COOLEST DAYS THROUGH
FRIDAY, WITH HIGHS IN THE MID 40S NORTH TO LOWER 50S ELSEWHERE.
NIGHTTIME LOWS WILL BE ON THE COOL SIDE AS WELL, ESPECIALLY WHEN
HIGH PRESSURE IS OVERHEAD LATE THIS WEEK. STAY TUNED AS WE MAY
BEGIN FROST/FREEZE HEADLINES LATER THIS WEEK INTO THE WEEKEND. IF
THAT IS THE CASE, SOME HEADLINES MAY BE NEEDED.
