DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0646 AM CST WED NOV 07 2012
VALID 071300Z - 081200Z
...NO TSTM AREAS FORECAST...
...EAST COAST...
A VERY DYNAMIC AND COMPLEX UPPER TROUGH WAS DRIVING INTENSE
CYCLOGENESIS OFF THE EASTERN SEABOARD THIS MORNING. TSTM PROSPECTS
OVER MOST AREAS WILL REMAIN LIMITED BY LACK OF APPRECIABLE
CONVECTIVE INSTABILITY. ONE EXCEPTION MAY BE SPORADIC ISOLATED
THUNDER IN SLANTWISE CONVECTION EMBEDDED WITHIN BANDED MIXED-PHASE
PRECIPITATION SPREADING WWD ACROSS NJ AND PA LATER THIS MORNING.
TSTMS MAY ALSO ACCOMPANY PRONOUNCED ASCENT AND MOISTURE FLUX
SPREADING NORTHEAST ACROSS THE NEW ENGLAND COASTAL WATERS THROUGH
TONIGHT. A COUPLE OF THESE STORMS MAY CROSS CAPE COD AND ADJACENT
ISLANDS BUT THE BULK OF THIS ACTIVITY SHOULD REMAIN OFFSHORE AND
ISOLATED IN NATURE.
...WEST COAST...
A DEEP TROUGH IS FORECAST TO DEVELOP SSEWD FROM THE GULF OF AK
TOWARD THE PACIFIC NORTHWEST AND OFFSHORE WATERS THROUGH EARLY
THURSDAY. LOWERING STATIC STABILITY AND HEIGHT FALLS WITH THIS
TROUGH WILL LIKELY SUPPORT SOME CONVECTION BUT GUIDANCE SUGGESTS
INSTABILITY WILL REMAIN TOO LIMITED OVER LAND AREAS TO SUPPORT A 10
PERCENT GENL TSTM AREA.
