CONCERNING...SEVERE THUNDERSTORM WATCH 149...

VALID 090156Z - 090330Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 149
CONTINUES.

SUMMARY...A SEVERE THREAT SHOULD CONTINUE ACROSS WW 149 OVER THE
NEXT FEW HOURS. WIND DAMAGE AND LARGE HAIL WILL BE POSSIBLE WITH THE
STRONGER CELLS. WW ISSUANCE TO THE EAST OF WW 149 CAN NOT BE RULED
OUT.

DISCUSSION...A MESOSCALE CONVECTIVE SYSTEM IS CURRENTLY ONGOING FROM
SCNTRL KS SWD INTO CNTRL OK LOCATED ALONG THE ERN EDGE OF A CORRIDOR
OF MODERATE INSTABILITY. THE THUNDERSTORMS ARE BEING SUPPORTED BY A
SHORTWAVE TROUGH LOCATED FROM SCNTRL KS EXTENDING SWD INTO WCNTRL OK
EVIDENT ON WATER VAPOR IMAGERY. THE INSTABILITY ALONG WITH
INCREASING LOW-LEVEL FLOW MAY ENABLE THE SEVERE THREAT ASSOCIATED
WITH THE MCS TO BE MAINTAINED TO AREAS EAST OF WW 149. THE STRONGER
CELLS COULD CONTAIN DAMAGING WIND GUSTS AND HAIL BUT THE THREAT IS
EXPECTED TO BECOME MORE ISOLATED AS THE STORMS MOVE INTO ERN OK AND
FAR ERN KS WHERE INSTABILITY IS WEAKER.
