TUESDAY THROUGH THURSDAY
A LOW PRESSURE SYSTEM WILL MOVE SLOWLY EAST NORTHEAST FROM THE
MID MISSISSIPPI RIVER VALLEY EAST NORTHEAST INTO THE SOUTHERN
GREAT LAKES FROM TUESDAY THROUGH THURSDAY. WARM AIR ADVECTION
WILL INITIALLY PROVIDE A CHANCE OF LIGHT RAIN FOR THE ENTIRE
AREA ON TUESDAY AND MAINLY SOUTH OF INTERSTATE 90 FROM TUESDAY
NIGHT INTO THURSDAY. THE SOUNDINGS SUGGEST THAT THERE MIGHT BE A
CHANCE FOR SOME LIGHT FREEZING RAIN ON TUESDAY NIGHT IN CENTRAL
AND SOUTHWEST WISCONSIN. THIS WILL BE HIGHLY DEPENDENT UPON HOW
FAST THE LOW LEVELS ARE ABLE TO SATURATE AND HOW WARM ARE THE
SURFACE TEMPERATURES. SINCE THERE IS PLENTY OF UNCERTAINTY ON
WHETHER THIS WILL EVEN OCCUR, OPTED TO JUST KEEP IT ALL RAIN AT
THIS TIME. DEPENDING ON THE LOCATION OF THE WARM FRONT ON
WEDNESDAY, THERE MIGHT BE A CHANCE FOR A FEW ELEVATED STORMS IN
NORTHEAST IOWA AND SOUTHWEST WISCONSIN.
HIGH TEMPERATURES WILL BE IN THE 40S ON TUESDAY AND WEDNESDAY,
AND RANGE FROM THE MID-40S TO MID-50S ON THURSDAY. LOW

NIGHT, AND FROM THE MID-30S TO LOWER 40S ON THURSDAY NIGHT.

SHORTWAVE TROUGH WILL EJECT NORTHEAST THROUGH THE REGION. THIS
