TONIGHT
HIGH PRESSURE WILL PROVIDE LIGHT WINDS AND MOSTLY CLEAR SKIES
TONIGHT. THIS WILL ALLOW TEMPERATURES TO COOL MORE THAN THE PAST
SEVERAL NIGHTS. DUE TO THIS, LOWERED THE LOW TEMPERATURES IN
CENTRAL AND NORTH-CENTRAL WISCONSIN TO THE NBM 10TH PERCENTILE.
THESE TEMPERATURES WERE IN THE 30S. THIS WILL RESULT IN PATCHY
TO SCATTERED FROST. THIS WAS FAR TOO LITTLE TO ISSUE A FROST
ADVISORY.
WEDNESDAY INTO WEDNESDAY NIGHT
HIGH PRESSURE OVER THE GREAT LAKES WILL KEEP THE DRIFTLESS
REGION DRY. HIGH TEMPERATURES WILL BE IN THE LOWER TO MID-60S.
LOW TEMPERATURES WILL RANGE FROM THE MID-30S TO AROUND 50. THE
COLDEST TEMPERATURES WILL BE IN CENTRAL AND NORTH-CENTRAL
WISCONSIN.
THURSDAY AFTERNOON INTO THURSDAY NIGHT
A COLD FRONT WILL APPROACH THE DRIFTLESS REGION FROM THE
NORTHERN PLAINS. THIS MAY RESULT IN A CHANCE (20-50 PERCENT) OF
SHOWERS WEST OF HIGHWAY 52 IN NORTHEAST IOWA AND SOUTHEAST
MINNESOTA. HIGH TEMPERATURES WILL BE IN THE LOWER AND MID-60S.
LOW TEMPERATURES WILL RANGE FROM THE MID-40S TO LOWER 50S.
FRIDAY INTO THE WEEKEND
THE 500 MB RIDGE WILL SHIFT EAST OF THE AREA. THIS WILL ALLOW A
SHORTWAVE TROUGH TO MOVE INTO THE DRIFTLESS REGION. AS THIS
OCCURS, THERE WILL BE PERIODIC SHOWERS AND MAYBE A FEW STORMS.
HIGH TEMPERATURES WILL BE IN THE 60S AND LOW TEMPERATURES WILL
RANGE FROM THE MID-40S TO MID-50S.
