DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1134 PM CST MON NOV 09 2009
VALID 101200Z - 111200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
PROGRESSIVE/GENERALLY LOW AMPLITUDE WESTERLIES WILL REMAIN OVER THE
NORTHERN HALF OF THE CONUS THROUGH THE PERIOD...AHEAD OF A BROADER
UPPER TROUGH NEARING THE BRITISH COLUMBIA/PACIFIC NORTHWEST COAST.
FARTHER SOUTH...TROPICAL STORM IDA IS EXPECTED TO BECOME
INCREASINGLY EXTRATROPICAL /REFERENCE NHC FORECASTS/ OVER THE
SOUTHEAST STATES AS IT PHASES WITH A SOUTHERN STREAM BRANCH OF
MODEST WESTERLIES/UPPER TROUGH CROSSING THE CENTRAL GULF COAST
STATES.
...NORTHEAST GULF COAST...
AS TROPICAL STORM IDA MOVES ONSHORE AND GRADUALLY WEAKENS/BECOMES
INCREASINGLY EXTRATROPICAL...ENHANCED LOW LEVEL WINDS ON THE EASTERN
PERIPHERY OF REMNANT IDA WILL EXIST ACROSS THE NORTHERN HALF OF FL
INTO ADJACENT PORTIONS OF GA/AL. EVEN WITH AMPLE LOW LEVEL SHEAR/SRH
FOR STORM ROTATION...IT STILL APPEARS THAT A RELATIVELY STABLE
AIRMASS WILL HOLD IN MOST INLAND AREAS. LIMITED SURFACE BASED
DESTABILIZATION/WEAK LAPSE RATES ARE EXPECTED SOUTH OF AN EFFECTIVE
FRONT ALONG THE FL/GA BORDER...AS THE RICHEST MARITIME AIRMASS
/73-75 F SURFACE DEWPOINTS/ OTHERWISE SHOULD TEND TO REMAIN CONFINED
TO THE IMMEDIATE FL GULF COAST AND OFFSHORE AREAS. WILL MAINTAIN LOW
TORNADO/CONVECTIVE WIND PROBABILITIES FOR THE PERIOD...BUT OVERALL
POTENTIAL APPEARS LIMITED AT THIS TIME GIVEN THE AFOREMENTIONED
FACTORS.
