DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1013 AM CST THU NOV 27 2014

VALID 271630Z - 281200Z

...NO TSTM AREAS FORECAST...

...SUMMARY...
NO SUBSTANTIAL THUNDERSTORM RISK IS EXPECTED THIS THANKSGIVING
ACROSS THE CONTIGUOUS UNITED STATES.

...SYNOPSIS...
THE LARGE-SCALE PATTERN WILL BE DOMINATED BY A MIDLEVEL TROUGH OVER
THE ATLANTIC COAST AND A RIDGE OVER THE ROCKIES...WITH A COLD AND/OR
DRY AIR MASS COVERING MOST OF THE CONUS.  THE LONE AREAS WITH ANY
POTENTIAL FOR CONVECTION WILL BE ALONG THE ORE/EXTREME NW CA COASTS
IN ADVANCE OF A SERIES OF ERN PAC SHORTWAVE TROUGHS...AND ERN NC
THIS AFTERNOON.  MARGINAL BUOYANCY WAS NOTED IN THE 12Z SLE SOUNDING
/MUCAPE OF 150 J PER KG ROOTED AT 700 MB/ AND ISOLATED LIGHTNING
FLASHES HAVE BEEN OBSERVED NEAR THE SW ORE COAST IN THE PAST HOUR.
HOWEVER...THE RISK FOR LIGHTNING INLAND IS QUITE LIMITED.
LIKEWISE..DESPITE THE POTENTIAL FOR VERY WEAK BUOYANCY AND SHALLOW
CONVECTION ACROSS ERN NC THIS AFTERNOON BENEATH THE MIDLEVEL THERMAL
TROUGH...THE THUNDERSTORM RISK IS TOO MARGINAL TO WARRANT THE
ADDITION OF ANY OUTLOOK AREAS.
