0607 PM CDT WED MAY 27 2026
AREAS AFFECTED...PORTIONS OF CENTRAL WISCONSIN
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 272307Z - 280030Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...THE SEVERE RISK ASSOCIATED WITH AN ONGOING MULTICELL
CLUSTER ACROSS CENTRAL WISCONSIN SHOULD GRADUALLY DECREASE OVER THE
NEXT 1-2 HOURS. ISOLATED LARGE HAIL AND DAMAGING WIND GUSTS REMAIN
POSSIBLE IN THE MEANTIME, HOWEVER.
DISCUSSION...A MULTICELL CLUSTER WITH A EMBEDDED SUPERCELL
STRUCTURES CONTINUES TO TRACK SOUTHWARD ALONG AND WEST OF THE I-39
CORRIDOR IN CENTRAL WISCONSIN HAVING PRODUCED SEVERAL REPORTS OF
HAIL UP TO 2" IN DIAMETER AND DAMAGING WIND GUSTS IN THE WAUSAU,
WISCONSIN, VICINITY OVER THE PAST 1-2 HOURS. EXPECTATION IS FOR THIS
CLUSTER TO PERSIST FOR ANOTHER HOUR OR TWO AS IT PROPAGATES
SOUTHWARD ALONG AN EAST-WEST ORIENTED COLD FRONT AND TO THE WEST OF
A WEAK, NORTH-SOUTH ORIENTED LAKE BREEZE. LATEST OBJECTIVE ANALYSIS
INDICATES THAT AVAILABLE BUOYANCY GENERALLY DECREASES WITH SOUTHWARD
EXTENT. COUPLED WITH THE GRADUAL ONSET OF NOCTURNAL LOW-LEVEL
COOLING/STABILIZATION, THIS SHOULD YIELD A GRADUAL WEAKENING OF THIS
CLUSTER WITH TIME. MODESTLY STEEP MID-LEVEL LAPSE RATES AND AROUND
30 KTS OF EFFECTIVE SHEAR AMID MODERATELY STRONG NORTHWESTERLY FLOW
ALOFT (AS SAMPLED BY THE GRB VWP) WILL CONTINUE TO PROMOTE A RISK
FOR LARGE HAIL WITH THE STRONGEST UPDRAFTS IN THE MEANTIME, HOWEVER.
STEEP LOW-LEVEL LAPSE RATES WEST OF THE LAKE BREEZE BOUNDARY WILL
ALSO SUPPORT A CONTINUED THREAT FOR ISOLATED DAMAGING WIND GUSTS.
