AREAS AFFECTED...NORTH-CENTRAL MINNESOTA
CONCERNING...SEVERE THUNDERSTORM WATCH 651...
VALID 032323Z - 040100Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 651
CONTINUES.
SUMMARY...A LOCAL CORRIDOR OF INCREASING DAMAGING WIND POTENTIAL
APPEARS TO BE EMERGING ACROSS PORTIONS OF NORTH-CENTRAL MINNESOTA.
WIDESPREAD TREE DAMAGE MAY BE POSSIBLE WITH THESE STORMS AS THEY
MOVE EAST OVER THE NEXT 1-2 HOURS.
DISCUSSION...A COUPLE OF INTENSE THUNDERSTORM CORES HAVE DEVELOPED
ON THE SOUTHERN EDGE OF A NORTH-SOUTH LINE OF THUNDERSTORMS. THESE
SOUTHERN MOST THUNDERSTORMS APPEAR TO BE INTERACTING WITH A
WEST-TO-EAST FRONTAL ZONE/NORTH-SOUTH TEMPERATURE GRADIENT CENTERED
AROUND 700 MB. RECENT 88D RADIAL VELOCITY DATA FROM THE DULUTH, MN,
RADAR HAVE SHOWN A MARKED INCREASE IN VELOCITIES AS THESE STORMS
INTERACT WITH THE AFOREMENTIONED TEMPERATURE GRADIENT. THESE
THUNDERSTORMS ARE LIKELY INGESTING MODERATELY UNSTABLE AIR FRONT THE
SOUTH, WITH MUCAPE VALUES AROUND 2000 J/KG. HOWEVER, INSTABILITY
QUICKLY WANES WITH EAST/NORTHEAST EXTEND AS EAST/NORTHEAST WINDS
ACROSS NORTHEAST MINNESOTA HAVE MAINTAINED A COOLER AIRMASS OFF LAKE
SUPERIOR. THAT SAID, THE DEGREE OF INSTABILITY TO THE
SOUTH/SOUTHWEST OF THE ONGOING THUNDERSTORMS AND STRONG VERTICAL
SHEAR WILL CONTINUE TO SUPPORT A DAMAGING WIND THREAT EVEN INTO THE
INCREASINGLY HOSTILE THERMODYNAMIC ENVIRONMENT.
