VALID 271200Z - 281200Z

...NO SVR TSTM AREAS FORECAST...

A BROAD ZONE OF SOUTHWEST FLOW WILL REMAIN IN PLACE ACROSS THE CONUS
THROUGH THE DAY 2 PERIOD AS A POWERFUL UPPER-LOW DEVELOPS AND MOVES
INLAND ACROSS THE PACIFIC NORTHWEST. SOME THUNDERSTORM ACTIVITY MAY
DEVELOP IN THE PACIFIC NORTHWEST AND IN THE INTERMOUNTAIN WEST
MONDAY ASSOCIATED WITH THE STRONG ASCENT AHEAD OF THE APPROACHING
LOW/TROUGH.

THE GREATEST THREAT FOR THUNDERSTORM ACTIVITY SHOULD OCCUR IN THE
PLAINS AND UPPER MIDWEST WHERE A STRONG LOW-LEVEL JET IS FORECAST TO
DEVELOP MONDAY AND MONDAY NIGHT. ALTHOUGH INSTABILITY/MOISTURE
RETURN WILL REMAIN WEAK ACROSS THE REGION...SCATTERED THUNDERSTORMS
MAY DEVELOP IN A REGION OF WARM ADVECTION FROM OK/N TX EXTENDING
NNEWD INTO IA/MN AND WI. THUNDERSTORM COVERAGE WOULD LIKELY BE
GREATEST FROM NEAR PEAK HEATING INTO THE EVENING HOURS AS THE
LOW-LEVEL JET STRENGTHENS. A FEW OF THE BETTER ORGANIZED
THUNDERSTORMS COULD CONTAIN HAIL DUE TO COLD TEMPS ALOFT AND
STEEPENING LAPSE RATES AS MID-LEVEL FLOW STRENGTHENS AHEAD OF A
STRONG MID-LEVEL JET EJECTING OUT OF THE BASE OF THE TROUGH.
