VALID 111200Z - 121200Z

...NO SVR TSTM AREAS FORECAST...

A MERIDIONAL UPPER-TROUGH OVER THE ROCKIES WILL MOVE EWD INTO THE
PLAINS STATES DURING THE DAY ON MONDAY. THE LOW-LEVEL MOIST AXIS
SHOULD REMAIN WELL EAST OF THE STRONGER FORCING ASSOCIATED WITH THE
TROUGH UNTIL AFTER DARK. ALTHOUGH A FEW THUNDERSTORMS MAY DEVELOP
MONDAY AFTERNOON ACROSS THE TX COASTAL PLAINS...MOST OF THE
THUNDERSTORM ACTIVITY SHOULD HOLD OFF UNTIL LATE EVENING OR AFTER
MIDNIGHT. THE GREATEST CHANCE OF CONVECTIVE DEVELOPMENT SHOULD BE
ACROSS ERN AR...LA AND SE TX WHEN THE LARGE-SCALE ASCENT ASSOCIATED
WITH THE TROUGH AND THE LOW-LEVEL MOISTURE PHASE TOGETHER. ALTHOUGH
WIND SHEAR WILL BE ADEQUATE FOR ORGANIZED STORMS...IT APPEARS
INSTABILITY WILL BE WEAK ACROSS THE REGION. FOR THIS REASON...ANY
SEVERE THREAT SHOULD REMAIN MARGINAL AND ISOLATED DURING THE
OVERNIGHT PERIOD.

ELSEWHERE...AN UPPER-LEVEL DISTURBANCE WILL MOVE ONSHORE IN THE
PACIFIC NORTHWEST MONDAY AFTERNOON. THUNDERSTORMS WILL BE POSSIBLE
DUE TO THE COLD AIR ALOFT AND STRONG LIFT ASSOCIATED WITH THE EXIT
REGION OF A MID-LEVEL JET. HOWEVER...NONE OF THE ACTIVITY IS
EXPECTED TO REACH SEVERE LIMITS.
