AREAS AFFECTED...PORTIONS OF COULEE REGION INTO CENTRAL WISCONSIN
CONCERNING...TORNADO WATCH 103...
VALID 132246Z - 140015Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 103 CONTINUES.
SUMMARY...A FAVORABLE CORRIDOR FOR TORNADOES WILL EXIST ALONG THE
WARM FRONT OVER THE NEXT 2-3 HOURS. AS ADDITIONAL STORMS FORM THIS
EVENING, STORM INTERFERENCE MAY EVENTUALLY MODULATE THE TORNADO
THREAT. LARGE TO VERY-LARGE HAIL IS ALSO POSSIBLE.
DISCUSSION...A FAVORABLE CORRIDOR FOR TORNADOES EXISTS ALONG THE
WARM FRONT FROM WEST-CENTRAL WISCONSIN INTO CENTRAL WISCONSIN. HERE,
LOW-LEVEL SHEAR WILL BE MAXIMIZED AND WILL LIKELY INCREASE EARLY
THIS EVENING AS 850 MB WINDS INTENSIFY. THE STRONGEST STORM IS
CURRENTLY ALONG THE GOODHUE/WABASHA COUNTY LINE. THIS STORM POSES
THE GREATEST THREAT FOR LARGE/VERY-LARGE HAIL AND TORNADOES IN THE
NEAR TERM. THE MAIN QUESTION WILL BE WHETHER A STORM CAN BECOME
DOMINANT AND MOVE ALONG THE WARM FRONT. THERE WILL LIKELY BE A
WINDOW DURING THE NEXT 2-3 HOURS WHERE THIS IS POSSIBLE. BEYOND THAT
TIME, INCREASING LOW-LEVEL WARM ADVECTION WILL PROBABLY PROMOTE
ADDITIONAL STORMS AND STORM INTERACTIONS WILL MAKE THE TORNADO RISK
LESS CLEAR.
