   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.
