THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 299
CONTINUES.
SUMMARY...AN ISOLATED LARGE HAIL AND DAMAGING WIND THREAT WILL
ACCOMPANY A SMALL CLUSTER OF STORMS MOVING INTO CENTRAL WISCONSIN
THIS MORNING.
DISCUSSION...WARM ADVECTION OVER THE OUTFLOW FROM EARLIER MORNING
CONVECTION HAS PROMOTED A FEW STRONGER/DEEPER THUNDERSTORMS WITHIN
THE NORTHERN COULEE REGION. THIS ACTIVITY IS ON THE FRINGE OF THE
STEEPER MID-LEVEL LAPSE RATES AND EFFECTIVE SHEAR (PERHAPS AROUND
25-30 KT). IT IS NOT CLEAR HOW FAR EAST THIS COMPLEX OF STORMS WILL
PROGRESS AS BUOYANCY AND SHEAR DECREASE WITH EASTWARD EXTENT AND THE
LOW-LEVEL JET WILL WEAKEN. THE CURRENT THINKING IS THAT ISOLATED
LARGE HAIL AND PERHAPS STRONG/DAMAGING WINDS ARE POSSIBLE OVER THE

MORNING.
