AREAS AFFECTED...NERN/ERN MO

CONCERNING...TORNADO WATCH 367...

VALID 282035Z - 282230Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 367 CONTINUES.

SUMMARY...SUPERCELLS APPEAR IMMINENT WITH TORNADOES POSSIBLY
DEVELOPING BY 21-22Z.

DISCUSSION...LATEST RADAR TRENDS SHOW CELLS RAPIDLY DEVELOPING ON
THE OUTFLOW BOUNDARY OVER NERN MO...FROM KNOX COUNTY SEWD. THIS AREA
IS AN ENVIRONMENT CONSISTING OF AROUND 300 M2/S2 EFFECTIVE SRH ALONG
WITH A SLIGHTLY SHELTERED/MOIST BOUNDARY LAYER AND PLUME OF
LOW-LEVEL LAPSE RATES FEEDING INTO THE AREA.

AIR TO THE E OF THE KNOX COUNTY CELL IS A BIT COOL...BUT THE
BOUNDARY COULD MOVE EWD. STILL...THE MOST LIKELY SCENARIO IS FOR
THESE CELLS TO SLOW DOWN AS THEY TAKE ROOT INTO THE BOUNDARY
LAYER...THEN TURN/PROPAGATE SEWD ALONG THE BOUNDARY WITH A TORNADO
THREAT. OTHER CELLS THAT CONTINUE MOVING IN A RELATIVELY LEFTWARD
DIRECTION MAY STILL YIELD A HAIL THREAT FARTHER E.
