CONCERNING...TORNADO WATCH 251...

VALID 302052Z - 302245Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 251 CONTINUES.

SUMMARY...SVR WEATHER THREAT CONTINUES ACROSS A LARGE PORTION OF THE
WATCH AREA INCLUDING AN ENHANCED RISK FOR DAMAGING WINDS ACROSS SE
IA AND NW IL.

DISCUSSION...RECENT REGIONAL RADAR IMAGERY SHOWS A CONVECTIVE LINE
EXTENDING FROM SE IA INTO NE/E-CNTRL MO THEN SWWD THROUGH CNTRL MO.
A PORTION OF THIS LINE HAS SHOWN AN INTENSIFYING TREND AS IT MOVES
NEWD ACROSS SE IA AND INTO NW IL. THE ORIENTATION OF THIS LINE
PLACES IT NEARLY PERPENDICULAR TO THE SHEAR VECTORS AND THE AREA
AHEAD OF IT WILL LIKELY HAVE AN ENHANCED RISK FOR DAMAGING WINDS
/AND POTENTIAL AN EMBEDDED TORNADO/ AS A RESULT. CONVECTIVE LINES
REMAIN POSSIBLE ELSEWHERE WITH A CONTINUED THREAT OF DAMAGING WINDS
AND POSSIBLY A TORNADO.
