VALID 151200Z - 161200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
STRONG WSWLY MID-UPPER LEVEL FLOW WILL SPREAD FARTHER INLAND ACROSS
THE NWRN U.S. AND THROUGH THE NRN ROCKIES TO THE NRN PLAINS. THIS
WILL ALLOW SRN STREAM TROUGHING TO SHIFT ENEWD THROUGH THE CENTRAL
STATES/MS VALLEY. IN THE LOW LEVELS...A SURFACE BOUNDARY EXTENDING
FROM SC/CENTRAL GA SWWD THROUGH SRN AL TO THE WRN GULF OF MEXICO
SHOULD REMAIN QUASI-STATIONARY ON SUNDAY WITHIN DEEP SWLY FLOW
REGIME EXTENDING FROM S TX TO THE CAROLINAS/MID-ATLANTIC STATES.
DESPITE A MOIST AIR MASS RESIDING ALONG AND S OF THE SURFACE
BOUNDARY OVER THE GULF COAST/SERN STATES...WEAK LAPSE RATES AND
LIMITED SURFACE HEATING WILL RESULT IN ONLY WEAK INSTABILITY. THIS
COMBINED WITH WEAK LOW LEVEL WAA SHOULD SUPPORT SHOWERS AND EMBEDDED
TSTMS ACROSS THIS REGION ON DAY 2...BUT THE WEAK INSTABILITY WILL
PRECLUDE A THREAT FOR SEVERE WEATHER.
