DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0649 AM CST FRI JAN 30 2009
VALID 301300Z - 311200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS...
AMPLIFIED E PACIFIC RIDGE/ERN NOAM TROUGH PATTERN WILL SOMEWHAT
DEAMPLIFY THIS PERIOD AS SHORTWAVE IMPULSE NOW NEARING 135W
CONTINUES ESE INTO THE CANADIAN RCKYS. FARTHER E/SE...A SERIES OF
WEAKER DISTURBANCES NOW CROSSING THE MS VLY WILL TEMPORARILY
REINFORCE LARGER SCALE TROUGH IN THE EAST. THIS SETUP WILL MAINTAIN
COOL AND/OR DRY CONDITIONS AT LWR LEVELS OVER MOST OF THE CONUS.
...CNTRL/SRN FL...
WEAK COLD FRONT NOW OVER CNTRL FL WILL CONTINUE STEADILY SE ACROSS
THE REMAINDER OF THE PENINSULA TODAY...WELL AHEAD OF LEAD SHORTWAVE
IMPULSE APPROACHING FROM THE LWR MS VLY. THE BOUNDARY WILL BE
ACCOMPANIED BY BOTH PRE- AND POST-FRONTAL CONVECTION. BUT WARM
EQUILIBRIUM LEVELS IN OBSERVED AND FCST SOUNDINGS SUGGEST MINIMAL
LIKELIHOOD FOR ACTIVITY SUFFICIENTLY DEEP AND/OR COLD-TOPPED TO
SUPPORT APPRECIABLE CHARGE SEPARATION. THUS...THE POTENTIAL FOR
OVERLAND THUNDER LOOKS LOW.
