NWS STORM PREDICTION CENTER NORMAN OK
0644 AM CST WED FEB 09 2011
VALID 091300Z - 101200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS/FORECAST...
BROAD...SLOWLY PROGRESSIVE LARGE SCALE TROUGH WILL PERSIST OVER THE
LWR 48 THIS PERIOD AS E PACIFIC RIDGE FINALLY EDGES EWD IN RESPONSE
TO STRONG SYSTEM NOW NEARING 45N/150W. SATELLITE SUGGESTS THAT
SHORTWAVE IMPULSE NOW OVER THE SRN PLNS HAS REACHED ITS MAXIMUM
INTENSITY. THE SYSTEM SHOULD WEAKEN AS IT CONTINUES E IN CONFLUENT
FLOW OVER THE LWR MS VLY/SERN STATES THROUGH EARLY THU.
AT THE SFC...OTHER THAN OVER THE FL PENINSULA...POLAR...ARCTIC OR
CONTINENTAL AIR WILL PREVAIL OVER THE CONUS THROUGH THE PERIOD.
ASSOCIATED DRY AND OR STATICALLY STABLE ENVIRONMENT SHOULD PRECLUDE
TSTM DEVELOPMENT. MARITIME AIR NOW LOCATED OVER CUBA AND THE SRN
BAHAMAS WILL SPREAD N/NW ACROSS SRN AND CNTRL FL LATER TODAY AND
TONIGHT AHEAD OF WEAKENING SYSTEM CROSSING THE INTERIOR SERN U.S.
BUT ABSENCE OF LARGE SCALE FORCING FOR ASCENT AND LOW LVL SOURCES OF
UPLIFT WILL LIMIT LIKELIHOOD FOR DEEP CONVECTION.
WHILE ISOLD THUNDER MAY OCCUR OVER NRN GULF OF MEXICO ALONG SRN
FRINGE OF ASCENT ASSOCIATED WITH SRN PLNS WAVE...AND ISOLD STORMS
MAY FORM LATE IN THE PERIOD OFF THE FL E CST...THIS ACTIVITY SHOULD
REMAIN OFFSHORE.
