DISCUSSION
ASIDE FROM A 15-20% CHANCE FOR AN ISOLATED SHOWER OR THUNDERSTORM
NEAR LAKE MICHIGAN THIS AFTERNOON, DRY CONDITIONS ARE EXPECTED
THROUGH TUESDAY. BREEZY NORTH-NORTHWEST WINDS WILL PREVAIL THROUGH
SUNDAY WITH GUSTS PEAKING AROUND 20-25 MPH EACH AFTERNOON.
OTHERWISE, SEASONABLE TEMPERATURES (IN THE 70S TO AROUND 80
DEGREES) WILL BE IN STORE THROUGH TUESDAY WITH DAILY MIXING
HEIGHTS AROUND 4000-6000 FT AND AFTERNOON RH VALUES AROUND 40-60%.
ANOTHER STORM SYSTEM IS FORECAST TO MOVE THROUGH THE GREAT LAKES

CHANCES FOR SHOWERS AND THUNDERSTORMS. HOWEVER, EXACT TIMING AND
COVERAGE OF SHOWERS/STORMS LOCALLY REMAINS UNCERTAIN.
