AREAS AFFECTED...FAR NERN SD...PARTS OF CNTRL/SRN MN...AND FAR WRN
WI
CONCERNING...TORNADO WATCH 255...
VALID 142216Z - 142315Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 255 CONTINUES.
SUMMARY...SEVERE THREAT CONTINUES ACROSS MAINLY SERN PORTIONS OF WW
255 IN S-CNTRL/SERN MN.
DISCUSSION...AN ARCING BAND OF THUNDERSTORMS EXTENDS ACROSS FAR NERN
SD INTO PARTS OF CNTRL/SRN MN AS OF 2215Z. A SFC WARM FRONT IS
ANALYZED FROM CNTRL MN INTO SWRN WI...AND IT SHOULD SHIFT ONLY
SLOWLY NWD/EWD WITH TIME. RECENT RADAR TRENDS SUGGEST CONVECTION IS
BECOMING QUICKLY ELEVATED ABOVE THE WARM FRONT AND WEAKENING FROM
FAR NERN SD INTO MUCH OF CNTRL MN. A LINE OF THUNDERSTORMS EXTENDING
FROM RICE SWD TO FREEBORN COUNTY MN SHOULD CONTINUE EWD AND POSE
MAINLY A DAMAGING WIND THREAT AS IT MOVES INTO WW 256. HOWEVER...
BACKED SELY SFC WINDS AND EFFECTIVE SRH OF 100-200 M2/S2 SHOULD
ALLOW FOR EMBEDDED CIRCULATIONS WITHIN THE LINE TO POSE AN ISOLATED
TORNADO THREAT IN THE SHORT TERM. COUNTIES CAN CONTINUE TO BE
CLEARED FROM WW 255 FROM SW TO NE AS THE ARC OF THUNDERSTORMS
CONTINUES NWD/EWD. FINALLY...A SMALL LOCAL EXTENSION IN AREA MIGHT
BE NEEDED INTO FAR W-CNTRL WI TO THE E OF THE TWIN CITIES DEPENDING
ON CONVECTIVE TRENDS IN THE NEXT HOUR OR SO.
