THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 330
CONTINUES.
SUMMARY...A WIND THREAT WILL CONTINUE ACROSS WW 330...BUT THE THREAT
IS NOT EXPECTED TO WARRANT A NEED FOR ANOTHER WATCH INTO ND.
DISCUSSION...A LINE OF STRONG TO SEVERE STORMS CONTINUES TO PROGRESS
EWD ACROSS MT...AND WILL EVENTUALLY MOVE INTO NWRN ND. THE STRONGEST
STORMS CURRENTLY EXIST OVER MCCONE COUNTY IN CLOSER PROXIMITY TO
BETTER MOISTURE...AND MAY CONTAIN LARGE HAIL IN ADDITION TO SEVERE
WIND GUSTS. A WARM ADVECTION WING HAS MATERIALIZED RECENTLY IN
RESPONSE TO LIFT OVER THE COOLER AIR MASS TO THE N. WHILE STORM
COVERAGE COULD INCREASE...THIS COULD DISRUPT OVERALL ORGANIZATION A
BIT. WHILE ISOLATED SEVERE WIND GUSTS MAY PERSIST INTO NWRN ND...THE
OVERALL THREAT SHOULD NOT BE WIDESPREAD ENOUGH FOR ANOTHER WATCH.
