CONCERNING...TORNADO WATCH 113...
VALID 150403Z - 150500Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 113 CONTINUES.
SUMMARY...THREAT FOR EMBEDDED TORNADOES AND SWATHS OF WIND DAMAGE
WILL PERSIST ACROSS SOUTHERN AND SOUTHEASTERN LOWER MICHIGAN THROUGH
05-06Z.
DISCUSSION...RADAR IMAGERY SUGGESTS THE FORMATION OF A LARGER
MCV/COMMA HEAD STRUCTURE IN SOUTHEAST LOWER MI WITH PERSISTENT
CONVECTION. EMBEDDED MESOVORTICES HAVE BEEN OBSERVED WITHIN THE
COMMA HEAD, AND A SWATH OF LIKELY DAMAGING WINDS EXTENDS SOUTH OF
THE COMMA HEAD/MCV. THE TORNADO AND WIND THREAT ARE LIKELY TO
PERSIST FOR THE NEXT COUPLE OF HOURS WHILE THE CONVECTION DEVELOPS
EAST-SOUTHEASTWARD ALONG THE BUOYANCY GRADIENT, IN A ZONE OF STRONG
LOW-LEVEL FLOW/SHEAR.
FARTHER WEST INTO SOUTHWEST LOWER MI, THE THREAT FOR
MESOVORTICES/TORNADOES WILL PERSIST WHERE A N-S BOWING SEGMENT MOVES
EAST-SOUTHEASTWARD AND INTERSECTS A MORE E-W OUTFLOW SEGMENT NEAR
THE BORDERS OF BARRY/EATON AND KALAMAZOO/CALHOUN COUNTIES.
