LINE OF STORMS WILL BE MOVING THROUGH THE AREA THIS MORNING...MORE
INFORMATION ON THESE STORMS CAN BE FOUND IN SPECIAL WEATHER
STATEMENTS AND POSSIBLE ISOLATED WARNINGS. SOUTHEAST WINDS BEHIND
THE INITIAL BAND MAY BE SIGN OF WAKE LOW DEVELOPMENT AND WILL BE

AFTER THIS MORNING STORMS...ANTICIPATE SOME DECREASE IN COVERAGE
BEFORE STORMS INCREASE AGAIN THIS AFTERNOON WITH THE H850 TROUGH
SLIDING THROUGH THE UNSTABLE AIR MASS WITH CAPES OF NEAR 1500 THIS
AFTERNOON. SEVERE POTENTIAL WOULD DEPEND ON AMOUNT OF SUN FOR
FURTHER DESTABILIZATION. THE CHANCE OF STORMS WILL LINGER
INTO TUESDAY BUT LIKELY MORE FOCUSED EARLY IN THE DAY OVER NORTH
CENTRAL AND NORTHEAST WISCONSIN DUE TO FRONT DROPPING SOUTH OVER
THE AREA AND THE UPPER RIDGE MOVING INTO THE AREA FROM THE WEST.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY
ISSUED AT 337 AM CDT MON JUL 13 2015

QUIET WEATHER EXPECTED THROUGH MID WEEK AS THE UPPER RIDGE BUILDS
