NWS STORM PREDICTION CENTER NORMAN OK
0331 AM CDT MON JUL 14 2008
VALID 171200Z - 221200Z
...NRN PLAINS TO THE GRTLKS REGION...
MAIN CONCERN FOR THE MEDIUM RANGE WILL BE HOW GUIDANCE IS HANDLING
THE MID-LEVEL IMPULSE OVER THE NRN ROCKIES/SW CANADA DURING THE
MID-LATE WEEK PERIOD. 00Z GFS IS MORE AMPLIFIED/SLOWER WHILE THE
GFS ENSEMBLE MEANS AND 00Z ECMWF ARE DECIDEDLY MORE PROGRESSIVE AND
WEAKER WITH THIS IMPULSE. TIMING/MAGNITUDE OF THE DISTURBANCE WILL
HAVE IMPLICATIONS ON THE STRENGTH OF THE ATTENDANT COLD FRONT AND
PROSPECTS FOR ORGANIZED SVR WEATHER. AT THIS POINT...GIVEN MODEL
DISCREPANCIES...PREDICTABILITY WILL REMAIN LOW.
