VALID 091630Z - 101200Z
..NO SVR TSTM AREAS FORECAST
..SYNOPSIS
A COLD MID LEVEL LOW WILL CONTINUE TO DIG SEWD NEAR THE CENTRAL/SRN
CA COAST THROUGH TONIGHT...WHILE AN INTENSE NRN STREAM LOW
PROGRESSES EWD FROM THE MID MS VALLEY TO THE CENTRAL APPALACHIANS.
THE CA SYSTEM WILL BE ACCOMPANIED BY COLD MID LEVEL TEMPERATURES AND
CONDITIONALLY UNSTABLE LAPSE RATES WHICH WILL SUPPORT A THREAT FOR
ISOLATED THUNDERSTORMS. THE MAGNITUDE OF INSTABILITY WILL BE
LIMITED BY RATHER COOL SURFACE TEMPERATURES AND MODEST
MOISTURE...THUS SEVERE STORMS ARE NOT EXPECTED. ALONG THE SC/NC
COASTAL PLAIN...A CLUSTER OF ELEVATED THUNDERSTORMS WILL PERSIST AND
MOVE NEWD THROUGH THE DAY IN ASSOCIATION WITH A DEEPENING SURFACE
CYCLONE IN ADVANCE OF THE MID MS VALLEY LOW. IT APPEARS THAT ANY
SURFACE-BASED INSTABILITY AND RESULTANT SEVERE STORM THREAT SHOULD
REMAIN JUST OFFSHORE.
