AREAS AFFECTED...NERN NEB AND E CNTRL NEB THROUGH SE SD AND NW IA
CONCERNING...TORNADO WATCH 909...
VALID 290222Z - 290315Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 909 CONTINUES.
THREAT FOR ISOLATED LARGE HAIL AND DAMAGING WIND WILL PERSIST FOR
ANOTHER HOUR OR TWO. STORMS HAVE BECOME LESS ORGANIZED AND TRENDS
SHOULD BE FOR INTENSITIES TO CONTINUE DECREASING. STORMS ARE
APPROACHING ERN EDGE OF WW 909...BUT THREAT FARTHER EAST APPEARS TOO
LIMITED IN SPACE AND TIME TO JUSTIFY ANOTHER WW ISSUANCE.
STORMS WILL LIKELY CONTINUE DEVELOPING SEWD THROUGH ERN NEB AND WRN
IA OVERNIGHT WITHIN ZONE OF FORCING ASSOCIATED WITH SEWD ADVANCING
COLD FRONT AND SWLY LOW LEVEL JET. ISOLATED DAMAGING WIND AND LARGE
HAIL WILL REMAIN POSSIBLE NEXT COUPLE HOURS. HOWEVER...STABILIZING
EFFECTS OF NOCTURNAL COOLING SUGGESTS THE SEVERE THREAT WILL BECOME
INCREASINGLY MARGINAL WITH TIME.
