NWS STORM PREDICTION CENTER NORMAN OK

...DISCUSSION...
DIFFERENCES BETWEEN THE GFS AND ECMWF -- ALREADY APPARENT AT THE
START OF THE PERIOD...INCREASE STEADILY WITH TIME...WITH VERY
DRASTIC DIFFERENCES EVIDENT BY LATE IN THE DAY 6 PERIOD.

PRIOR TO THIS...A COLD FRONT MOVING EWD ACROSS THE ERN HALF OF THE
CONUS DAYS 4 AND 5 /TUE. AND WED. OCT. 14 AND 15/ SHOULD SERVE AS A
FOCUS FOR CONVECTIVE DEVELOPMENT...BUT MINIMAL INSTABILITY AT BEST
SHOULD PRECLUDE ANY SEVERE THREAT.
