DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0755 PM CDT WED MAR 11 2015
VALID 120100Z - 121200Z
...NO SVR TSTM AREAS FORECAST...
...SUMMARY...
ISOLATED THUNDERSTORMS MAY PERSIST THROUGH MIDNIGHT ACROSS PARTS OF
THE SOUTHEAST STATES AND DEVELOP OVERNIGHT OVER EASTERN TEXAS AND
LOUISIANA.
...EASTERN TEXAS AND LOUISIANA...
A COMPACT CORRIDOR OF STRENGTHENING LOW-LEVEL SOUTH/SOUTHEAST FLOW
IS CONSISTENTLY PROGGED NEAR THE SABINE VALLEY IN ASSOCIATION WITH A
WEAK SHORTWAVE IMPULSE ALONG THE TEXAS GULF COAST. THIS WILL YIELD
AN INCREASE IN WARM-AIR ADVECTION WITH ISOLATED THUNDERSTORMS
FORMING OVERNIGHT. CONVECTION OVER LAND SHOULD REMAIN ELEVATED AS
ATTENDANT SURFACE CYCLONE DRIFTS SLOWLY NORTH OVER THE NORTHWEST
GULF. POOR MID-LEVEL LAPSE RATES PER 00Z LAKE CHARLES RAOB WILL
LIMIT INSTABILITY AND PRECLUDE A RISK OF SEVERE STORMS.
