AREAS AFFECTED...WI/SRN UPPER MI
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 261030Z - 261130Z
CONVECTION INCREASING IN COVERAGE AND INTENSITY INVOF THE UPPER MS
VALLEY MAY REQUIRE NEW WW ISSUANCE.
SURFACE ANALYSIS SHOWS A WEDGE OF SURFACE MOISTURE ARCING NWWD
ACROSS WI TOWARD E CENTRAL MN...ALONG THE COLD/OCCLUDED FRONT E OF
THE DEEPENING CENTRAL MN SURFACE LOW. STRONG LOW-LEVEL CONVERGENCE
ALONG THE FRONT IN CONJUNCTION WITH MODEST INSTABILITY WITHIN THE
MOIST AXIS IS SUPPORTING THE CONVECTIVE INCREASE NOTED IN BOTH RADAR
AND LIGHTNING DATA OVER THE PAST HOUR.
THE INCREASING CONVECTION IS OCCURRING WITHIN A KINEMATIC
ENVIRONMENT FEATURING STRONG SLY/SSWLY FLOW WITH HEIGHT.
OVERALL...THIS ENVIRONMENT APPEARS SUPPORTIVE OF ISOLATED DAMAGING
GUSTS WITH SMALL-SCALE LINE SEGMENTS. IF CONVECTION INDEED
CONTINUES TO INCREASE/ORGANIZE...NEW WW WILL LIKELY BECOME
NECESSARY.
