THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 199, 201
CONTINUES.
SUMMARY...THE RISK OF SEVERE GUSTS (SOME UPWARDS OF 75 MPH) WILL
CONTINUE SPREADING EASTWARD INTO EASTERN MONTANA -- WITHIN WW201.
DISCUSSION...HIGH-BASED THUNDERSTORMS MOVING EASTWARD INTO EASTERN
MT HAVE EVOLVED INTO A LOOSELY ORGANIZED SQUALL LINE ALONG A
NORTH/SOUTH-ORIENTED SURFACE TROUGH/CONFLUENCE ZONE. THIS BAND OF
STORMS WILL CONTINUE SPREADING EASTWARD IN TANDEM WITH THE LEADING
EDGE OF MIDLEVEL HEIGHT FALLS ACCOMPANYING A ROBUST MIDLEVEL TROUGH.
AROUND 40 KT OF MIDLEVEL WEST-SOUTHWESTERLY FLOW ORIENTED
PERPENDICULAR TO THE LEADING GUST FRONT AND A HOT/DRY PRE-CONVECTIVE
BOUNDARY LAYER WILL FAVOR A CONTINUED RISK OF SEVERE WIND GUSTS
(SOME POSSIBLY UP TO 75 MPH) WITH EASTWARD EXTENT (WITHIN WW201).
