MONDAY NIGHT THROUGH TUESDAY NIGHT
FROM MONDAY NIGHT INTO TUESDAY, A SHORTWAVE TROUGH WILL MOVE ALONG
THE US/CANADIAN BORDER, WORKING TO FLATTEN THE UPPER LEVEL
RIDGE OVER THE UPPER MISSISSIPPI RIVER. AS THIS OCCURS, A COLD
FRONT WILL MOVE SLOWLY SOUTHEAST THROUGH THE REGION ON TUESDAY.
FOR AREAS ALONG AND NORTH OF THE INTERSTATE 90 CORRIDOR, THE
TIMING OF THIS FRONT WILL ONLY BE FAVORABLE FOR ISOLATED TO
SCATTERED SHOWERS AND STORMS. DURING THE AFTERNOON AND EVENING,
0-1 KM CAPE WILL BE UP TO 1500 J/KG ALONG AND AHEAD OF THE COLD
FRONT IN NORTHEAST IOWA, AND SOUTHWEST AND CENTRAL WISCONSIN.
WITH THE BETTER 0-3 KM AND 0-6 KM SHEAR LOCATED WELL IN THE WAKE
OF THE FRONT, ORGANIZED SEVERE WEATHER LOOK UNLIKELY AT THIS
TIME.
LOW TEMPERATURES WILL RANGE FROM THE LOWER 50S TO MID-60S ON MONDAY
AND TUESDAY NIGHTS. HIGH TEMPERATURES WILL RANGE FROM THE MID-70S TO
LOWER 80S ON TUESDAY.
WEDNESDAY INTO THURSDAY

OF THE AREA ON WEDNESDAY NIGHT THROUGH THURSDAY. AGAIN THERE IS
LITTLE SHEAR LOCATED ACROSS THE AREA, SO ORGANIZED CONVECTION
LOOKS UNLIKELY AT THIS TIME.
