CURRENT REGIONAL RADAR IMAGERY AS OF 08Z THIS MORNING MAINLY
LIGHT RAIN SHOWERS OVER NORTHERN IL, SOUTHERN/CENTRAL WISCONSIN
AND CENTRAL MICHIGAN WITH THE UPPER LEVEL DISTURBANCE MOVING
THROUGH THE REGION IN THE WAKE OF A COOL FRONT THAT MOVED SOUTH
THROUGH THE AREA AND IS CURRENTLY DRAPED FROM WEST TO EAST OVER
SOUTHERN IL AND IN. A FEW LIGHT SHOWERS WILL LOOK TO MOVE INTO
NORTHERN IN AND SOUTHERN MI BUT WITH THE DRIER LOWER LEVELS
VIRGA WILL BE POSSIBLE UNTIL SOME MOISTENING OF THE LOWER LEVELS
OCCURS. SHOWERS EXPECTED TO BE ON THE LIGHT SIDE. IN THE WAKE OF
THE COOL FRONT COOLER TEMPERATURES TODAY AND INTO THURSDAY WITH
HIGHS TODAY IN THE 60S ACROSS THE AREA. SLIGHTLY WARMER
TEMPERATURES TOMORROW AS A WARM FRONTAL BOUNDARY AND RIDGING
OVER THE CENTRAL CONUS BEGINS TO PUSH EASTWARD INTO THE REGION.
BY SATURDAY HIGHS COULD APPROACH 80 DEGREES ESPECIALLY THE
SOUTHERN AND EASTERN PORTIONS OF THE CWA.
AS THIS WARM FRONT MOVES EASTWARD WE WILL SEE GRADUALLY WARMING
TEMPERATURES THROUGH SATURDAY BEFORE ANOTHER TROUGH DROPPING
FROM ALBERTA CANADA PUSHES SOUTHEASTWARD INTO THE REGION
BRINGING ANOTHER COLD FRONT YET THIS FRONT LOOKS A BIT MORE
DYNAMIC AS IT MOVES THROUGH AND BY SATURDAY AFTERNOON RAIN AND
THUNDERSTORMS LOOK FAIRLY LIKELY. THIS WOULD BE MUCH WELCOME
RAINFALL FOR THE AREA.
COOLER TEMPERATURES ARRIVE ON SUNDAY THROUGH MID WEEK WITH HIGHS
ONLY IN THE 60S AND LOWS IN THE 40S. ANOTHER REINFORCING SHOT OF
COOL AIR ARRIVES WITH ANOTHER TROUGH PUSHING INTO THE GREAT
LAKES REGION ON TUESDAY.
