AREAS AFFECTED...CENTRAL MINNESOTA INTO WEST-CENTRAL WISCONSIN
CONCERNING...SEVERE THUNDERSTORM WATCH 355...
VALID 192056Z - 192300Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 355
CONTINUES.
SUMMARY...LARGE HAIL UP TO GOLF-BALL SIZE AND DAMAGING WIND GUSTS
WILL REMAIN THE PRIMARY HAZARDS AS STORMS CONTINUE TO SPREAD
SOUTHEAST ACROSS THE WATCH AREA THIS AFTERNOON INTO EVENING.
DISCUSSION...AS OF 20:45 UTC, MOSAIC RADAR DATA INDICATED A LOOSELY
ORGANIZED CLUSTER OF THUNDERSTORMS ACROSS OTTER TAIL, WADENA, AND
CASS COUNTIES WITH MORE INTENSE, SEMI-DISCRETE STORMS NOTED IN MILLE
LACS AND KANABEC COUNTIES. THE SEMI-DISCRETE STORMS APPEAR TO BE
LOCATED IMMEDIATELY DOWNSTREAM FROM A WEAK SURFACE LOW, WHERE
LOW-LEVEL CONVERGENCE AND VERTICAL SHEAR ARE LIKELY BEING MAXIMIZED.
LATEST OBJECTIVE ANALYSIS SUGGESTS THAT THE INFLOW AIR MASS TO THESE
STORMS REMAINS MODERATELY UNSTABLE WITH MLCAPE OF AROUND 1000 J/KG,
WITH INCREASING BULK-SHEAR MAGNITUDES WITH SOUTHWARD EXTENT ACROSS
THE WATCH AREA. AS SUCH, THE GREATEST POTENTIAL FOR LARGE HAIL UP TO
GOLF-BALL SIZE IS EXPECTED WITH THE MORE DISCRETE STORMS MENTIONED
ABOVE, WHICH ARE IN CLOSER PROXIMITY TO THE STRONGER VERTICAL SHEAR.
LATEST SHORT-TERM MODEL GUIDANCE CONTINUES TO SUGGEST AN INCREASED
RISK FOR DAMAGING WINDS EVOLVING LATE THIS AFTERNOON INTO EVENING
FROM THE VICINITY OF THE ST. CROIX RIVER INTO PORTIONS OF
WEST-CENTRAL WI AS STORMS CONSOLIDATE IN TO CLUSTERS OR LINE
SEGMENTS.
