NWS STORM PREDICTION CENTER NORMAN OK
0127 AM CST SUN NOV 11 2007
VALID 131200Z - 141200Z
..NO SVR TSTM AREAS FORECAST...
..SYNOPSIS/FORECAST...
POWERFUL N PAC JET WILL CONTINUE EWD ACROSS THE PAC NW INTO THE NRN
PLAINS AND UPR MS VLY TUESDAY AND TUESDAY NIGHT. THE NWRN MEXICO
UPR LOW WILL BECOME WELL REMOVED FROM THE STRONGER FLOW AND REMAIN
IN PLACE THROUGH TUESDAY AND BEYOND. MEANWHILE...WEAKER SRN BRANCH
SYSTEMS OVER THE CNTRL PLAINS EARLY IN THE PERIOD WILL CONTINUE SEWD
AND DEAMPLIFY...BUT CONTRIBUTE TO CARVING OUT A BROAD TROUGH ACROSS
THE SERN STATES.
AT THE SFC...A RIDGE OF HIGH PRESSURE WILL REMAIN ANCHORED ACROSS
THE SERN STATES AND THE NRN GULF BASIN...LIMITING THE RETURN OF
QUALITY GULF/CARIBBEAN MOISTURE NWD. THE COLD FRONT SETTLING SEWD
ACROSS THE OH VLY AND SRN PLAINS MONDAY AND EARLY TUE WILL BECOME
ILL-DEFINED...AWAITING A FRESH SURGE OF CP AIR FOLLOWING THE MORE
INTENSE NRN STREAM JET. THIS NEW FRONT WILL REACH THE OH VLY...
OZARKS AND OK/N TX BY 12Z WED.
HIGHEST TSTM PROBABILITIES WILL LIKELY FAVOR THE FRONTAL ZONE FROM
NERN OK NEWD ACROSS THE OZARKS AND INTO PARTS OF THE
MIDWEST...ESPECIALLY EARLY IN THE DAY AS THE WEAKER SRN BRANCH WAVES
MOVE SEWD ATOP THE MOIST AXIS. BUOYANCY WILL NOT BE PARTICULARLY
ROBUST AND MID-TROPOSPHERIC LAPSE RATES POOR. THUS...SVR WEATHER IS
NOT ANTICIPATED.
OTHERWISE...BANDS OF STREAMER SHOWERS WILL LIKELY CONTAIN SPORADIC
TSTMS ALONG THE UPR TX COAST NWD INTO THE AR OZARKS WHERE SLY
LOW-LEVEL FLOW MAINTAINS MID 60S BOUNDARY LAYER DEW POINTS.
THERMODYNAMIC SET-UP DOES NOT APPEAR SUPPORTIVE OF ORGANIZED SVR
STORMS.
