AREAS AFFECTED...SOUTHERN WISCONSIN AND NORTHERN ILLINOIS
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 021930Z - 022100Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...A DOWNSTREAM WATCH WILL LIKELY BE NEEDED THIS AFTERNOON.
DISCUSSION...THE OUTFLOW BOUNDARY FROM THIS MORNING STALLED ACROSS
NORTHERN ILLINOIS AROUND MID-DAY AND HAS STARTED TO LIFT NORTH
THROUGH THE EARLY AFTERNOON. EXPECT THIS BOUNDARY TO CONTINUE TO
MOVE NORTH AS STRONG HEATING CONTINUES NORTH OF THE BOUNDARY.
ONGOING SUPERCELLS TO THE WEST WILL CONTINUE TO POSE A LARGE HAIL
AND DAMAGING WIND THREAT AS THEY STRADDLE THE BOUNDARY, MOVING EAST
THIS AFTERNOON AND INTO THE EVENING. A LOCALLY HIGHER TORNADO THREAT
MAY EXIST ALONG THIS BOUNDARY, ESPECIALLY IF ANY SUPERCELLS CAN
LATCH ON TO IT. GIVEN CURRENT TRENDS WITH STORMS TO THE WEST, A
DOWNSTREAM WATCH WILL LIKELY BE NEEDED BY 4 PM, BUT IF STORMS
DEVELOP FARTHER EAST ALONG THE BOUNDARY, A WATCH MAY BE NEEDED
EARLIER.
