DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0621 AM CST SAT NOV 30 2013

VALID 301300Z - 011200Z

...NO TSTM AREAS FORECAST...

...SYNOPSIS/FORECAST...
A QUASI-ZONAL LONGWAVE PATTERN WILL PREVAIL OVER THE CONUS THROUGH
TONIGHT...WITH A DEGREE OF AMPLIFICATION OCCURRING OVER ONTARIO AND
THE GREAT LAKES REGION VIA A SOUTHEASTWARD-DIGGING SHORTWAVE TROUGH.
A NIL TSTM POTENTIAL IS EXPECTED ACROSS THE CONUS GIVEN THE
WIDESPREAD PREVALENCE OF COLD/DRY CONTINENTAL TRAJECTORIES AND
STABLE CONDITIONS. WHILE SOME SHOWERS MAY OCCUR NEAR EAST COASTAL
PORTIONS OF FL/GA TODAY...BROAD SUBSIDENCE AND AN ASSOCIATED
MID-LEVEL INVERSION WILL LIKELY KEEP ANY TSTM POTENTIAL WELL
OFFSHORE IN THE ATLANTIC.

..GUYER/GARNER.. 11/30/2013
