NWS STORM PREDICTION CENTER NORMAN OK
1118 AM CDT THU OCT 30 2008
VALID 301630Z - 311200Z
...NO SVR TSTM AREAS FORECAST...
COMPACT UPPER TROUGH MOVING ACROSS SD/NEB WILL TRACK EAST-
SOUTHEASTWARD INTO THE MO VALLEY TODAY AND TONIGHT. THE ASSOCIATED
POCKET OF COLD TEMPERATURES ALOFT AND STEEP LAPSE RATES WILL YIELD
SUFFICIENT INSTABILITY FOR SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS THROUGH TONIGHT. TOWARD 12Z...FORCING ASSOCIATED WITH
UPPER TROUGH WILL IMPINGE ON RICHER LOW LEVEL THETAE AIRMASS...WHICH
MAY ENCOURAGE AN INCREASE IN AREAL COVERAGE OVER SOUTHEAST KS.
THERE IS SOME POTENTIAL FOR SMALL HAIL BY THAT TIME...BUT NO SEVERE
STORMS ARE ANTICIPATED.
