DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0946 AM CST WED MAR 02 2011

VALID 021630Z - 031200Z

...NO TSTM AREAS FORECAST...

...SYNOPSIS...
A PRONOUNCED MIDLEVEL SHORTWAVE TROUGH IS ROTATING NEWD OVER THE NW
WA COAST AS OF MID MORNING. SATELLITE IMAGERY AND 12Z SOUNDINGS
SUGGEST THAT INSTABILITY AND CONVECTIVE POTENTIAL WILL REMAIN
MINIMAL INLAND...THUS HAVE REMOVED THE TSTM OUTLOOK AREA. THE ONLY
OTHER AREA WITH ANY APPRECIABLE RISK FOR THUNDERSTORMS WILL BE
ACROSS CENTRAL/NE NV THIS AFTERNOON INTO TONIGHT. VERY WEAK
MIDLEVEL INSTABILITY WILL BE POSSIBLE /PER THE 12Z REV
SOUNDING/...BUT THE OVERALL THUNDERSTORM POTENTIAL APPEARS TOO LOW
TO ADD AN OUTLOOK AREA FOR NV.

ELSEWHERE...A RELATIVELY COOL CONTINENTAL AIR MASS COVERS THE CONUS
E OF THE ROCKIES...WHERE THUNDERSTORMS ARE NOT EXPECTED.

..THOMPSON.. 03/02/2011
