..ISOLATED SEVERE WEATHER EXPECTED TONIGHT...

SHORT/LONG TERM...
HIGH PRESSURE OVER THE MID-ATLANTIC STATES THIS MORNING
IS BRINGING SOUTHEAST FLOW INTO SOUTHEAST TEXAS AND SOUTHERN
LOUISIANA. TEMPS THIS MORNING HAVE MODERATED IN RESPONSE TO THE
FLOW OFF THE GULF.

THERE IS THE POTENTIAL FOR A FEW SEVERE THUNDERSTORMS TONIGHT AS
SOUTHEAST TEXAS AND SOUTHERN LOUISIANA ATMOSPHERE BECOMES UNSTABLE
AS THE REGION MOVES INTO THE WARM SECTOR AHEAD OF A COLD FRONT
THAT WILL PUSH THROUGH LATE TUESDAY MORNING. THE COMBINATION OF A
NEGATIVELY TILLED TROUGH TO THE NW SWINGING DOWN INTO THE REGION
ALONG WITH THE DEVELOPMENT OF THE 850MB LOW LEVEL JET 50 KT...
THE APPROACH OF THE LEFT FRONT ENTRANCE OF THE UPPER LEVEL JET...
RETURN FLOW OF MOISTURE OFF THE GULF WILL SUPPORT THUNDERSTORM
DEVELOPMENT. CAPES TO BE AROUND 1800 J/KG AND HELICITY AROUND 250
M2/S2 WITH THE WET BULB ZERO AROUND 8500 FT.

THE ONE LIMITING FACTOR AT THIS TIME WILL BE THE AMOUNT OF MOISTURE
FOR STORM DEVELOPMENT. PRECIP WATER WILL RANGE AROUND 1 TO 1.3
INCHES. THEREFORE ONLY ISOLATED SEVERE THUNDERSTORMS IS EXPECTED.

THE SEVERE THREAT WILL RANGE FROM DAMAGING WINDS TO LARGE HAIL
AND ISOLATED TORNADOS.

RAIN ENDING TOWARDS THE NOON HOUR TOMORROW WITH COLDER AIR
