THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 115
CONTINUES.
SUMMARY...THREAT FOR OCCASIONAL LARGE HAIL AND ISOLATED WIND DAMAGE
WILL CONTINUE ALONG A STALLED FRONT FOR THE NEXT COUPLE OF HOURS,
WITH ADDITIONAL STORM DEVELOPMENT EXPECTED INTO EASTERN IOWA.
DISCUSSION...THUNDERSTORMS DEVELOPED RAPIDLY ALONG A STALLED FRONT
IN THE PAST HOUR, AIDED BY LOW-LEVEL WARM ADVECTION. THE FRONT IS
EXPECTED TO MOVE LITTLE THE NEXT FEW HOURS AND WILL PROVIDE A FOCUS
FOR ADDITIONAL STORM DEVELOPMENT INTO EASTERN IA (WHERE A NEW SEVERE
THUNDERSTORM WATCH HAS JUST BEEN ISSUED). STORMS WILL LIKELY REMAIN
CONFINED TO THE FRONT AND WILL POSE A THREAT FOR LARGE HAIL WITH THE
INITIAL UPDRAFTS, AND ISOLATED WIND DAMAGE AS STORM COVERAGE
INCREASES AND SMALL BOWING SEGMENTS BECOME POSSIBLE ALONG THE
BOUNDARY. A BRIEF TORNADO MAY ALSO OCCUR WITH BOWING SEGMENTS
INTERACTING WITH THE FRONT. ONCE STORMS BECOME WIDESPREAD, STORM
INTENSITY WILL DECREASE GRADUALLY AND THE SEVERE THREAT WILL BEGIN
TO WANE CLOSE TO WATCH EXPIRATION TIME AT 07Z.
