AREAS AFFECTED...CNTRL THROUGH SERN ND

CONCERNING...SEVERE THUNDERSTORM WATCH 552...

VALID 290903Z - 291030Z

MARGINAL THREAT OF ISOLATED STRONG WIND GUSTS PERSISTS WITH LINE OF
STORMS MOVING THROUGH CNTRL ND. OTHER STORMS MAY MOVE INTO SERN ND
DURING THE NEXT COUPLE HOURS WITH A THREAT OF PRODUCING MAINLY LARGE
HAIL.

A SQUALL LINE EXTENDS TROUGH CNTRL ND FROM MINOT SWD TO BISMARK. THE
PORTION OF THE LINE OVER CNTRL ND IS MOVING EWD AT AROUND 25 KT. THE
LINE REMAINS SEMI-ORGANIZED WITH A ROTATING COMMA HEAD OBSERVED NEAR
MINOT AND WILL LIKELY CONTINUE EWD ALONG THE INSTABILITY GRADIENT
THROUGH THE EARLY MORNING. ISOLATED STRONG WIND GUSTS ARE POSSIBLE
ESPECIALLY ALONG THE BOWING SEGMENTS OF THE LINE. HOWEVER...THE
OVERALL WIND THREAT APPEARS TO BE SOMEWHAT LIMITED BY PRESENCE OF A
COOL/STABLE BOUNDARY LAYER. OTHER STORMS ARE DEVELOPING WITHIN A
ZONE OF WARM ADVECTION OVER NERN SD AND WILL LIKELY LIFT NEWD INTO
SERN ND DURING THE NEXT COUPLE HOURS. LARGE HAIL WILL BE THE MAIN
THREAT WITH THIS ACTIVITY.
