AREAS AFFECTED...PORTIONS OF SOUTHWESTERN WISCONSIN
CONCERNING...TORNADO WATCH 461...
VALID 252338Z - 260115Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 461 CONTINUES.
SUMMARY...A COUPLE OF ADDITIONAL TORNADOES ARE POSSIBLE WITH
SUPERCELLS ALONG A WARM FRONT OVER SOUTHWESTERN WI OVER THE NEXT FEW
HOURS.
DISCUSSION...A PAIR OF SUPERCELLS WITH A HISTORY OF TORNADOES
CONTINUES TO TRAVERSE A WARM FRONT, ALONG THE MN/WI BORDER. SURFACE
TEMPERATURES/DEWPOINTS IN THE UPPER 80S/MID 70S F IS CONTRIBUTING TO
1500-2000 J/KG MLCAPE ON THE IMMEDIATE SIDE OF THE WARM FRONT.
LATEST KARX NEXRAD DATA SHOWS THAT THE ONGOING SUPERCELLS MAY BE
CROSSING TO THE IMMEDIATE COOL SIDE OF THE FRONT. FURTHERMORE, THE
WARM FRONT BECOMES MORE SOUTH-SOUTHEASTERLY WITH EASTWARD EXTENT,
SUGGESTING THAT STORMS MOVING EAST TO EAST-NORTHEAST WILL HAVE MORE
OF A CROSSWISE COMPONENT OF VORTICITY TO INGEST, WHICH MAY LESSEN
TORNADO POTENTIAL TO A DEGREE. NONETHELESS, REGIONAL VADS ACROSS
SOUTHERN WI CONTINUE TO SHOW STRONG LOW-LEVEL SHEAR VIA
SIZEABLE/CURVED LOW-LEVEL HODOGRAPHS. AS SUCH, A COUPLE OF
ADDITIONAL TORNADOES REMAIN POSSIBLE WITH ANY STORMS THAT MANAGE TO
ANCHOR ALONG THE WARM FRONT OVER THE NEXT FEW HOURS.
