DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0949 AM CST THU NOV 29 2012
VALID 291630Z - 301200Z
...NO SVR TSTM AREAS FORECAST...
...NRN CA COAST...
A PERSISTENT BELT OF STRONG FLOW WILL BE MAINTAINED THROUGH THE
PERIOD OVER THE NRN CA REGION AS A LARGE SCALE UPPER TROUGH MOVES
LITTLE OVER THE NERN PACIFIC TO THE W OF BRITISH COLUMBIA. SEVERAL
SMALL SCALE IMPULSES WILL CONTINUE TO ROTATE THROUGH THE BASE OF THE
UPPER TROUGH AND INTO THE NRN CA/ORE COAST. AS SUCH...A CONTINUED
THREAT FOR INTERMITTENT ISOLD TSTMS WILL EXIST THROUGH DAYBREAK
FRIDAY NEAR THE COAST. A WEAKLY BUOYANT AIRMASS IN COMBINATION WITH
STRONG 50-60 KT WINDS IN THE LOWEST FEW THOUSAND FEET...MAY
FACILITATE THE POSSIBILITY OF STRONG MOMENTUM ALOFT BEING
TRANSPORTED TO THE SURFACE. THIS WOULD BE IN THE FORM OF A NON-ZERO
RISK FOR A DMGG WIND GUST WITH ANY VIGOROUS CONVECTIVE BAND THAT
MOVES ASHORE. ELSEWHERE...AN ISOLD TSTM OR TWO MAY DEVELOP LATE
TONIGHT OFF THE LOWER-MIDDLE TX COAST.
