...NO SVR TSTM AREAS FORECAST...

A WEST TO WEST NORTHWEST ZONAL FLOW PATTERN IS FORECAST ACROSS THE
CONUS ON SATURDAY. AT THE SFC...TWO AREAS OF LOW PRESSURE ARE
FORECAST WITH ONE MOVING EWD ACROSS THE OH VALLEY AND ANOTHER MOVING
SWD INTO THE SRN PLAINS. A COLD FRONT SHOULD ADVANCE SEWD ACROSS THE
SRN PLAINS...MID MS VALLEY AND OH VALLEY ALONG WHICH THUNDERSTORMS
COULD DEVELOP SATURDAY AFTERNOON AND EVENING. THE MODELS DEVELOP THE
GREATEST CONVECTIVE COVERAGE FROM KY AND TN EWD TO THE NC AND VA
COAST WHERE LOW-LEVEL FLOW SHOULD BE ENHANCED AND A MOIST AXIS
SHOULD BE IN PLACE WITH SFC DEWPOINTS POSSIBLY IN THE LOWER 50S F.
ALTHOUGH A THREAT FOR SMALL HAIL COULD DEVELOP...WEAK INSTABILITY IS
EXPECTED TO KEEP ANY THUNDERSTORM ACTIVITY BELOW SEVERE LIMITS.

OUT TO THE WEST...AN AREA OF THUNDERSTORM ACTIVITY COULD ALSO
DEVELOP ACROSS THE SRN AND CNTRL ROCKIES AHEAD OF A MINOR SHORTWAVE
TROUGH AND IN A STEEP LAPSE RATES ENVIRONMENT. THIS ACTIVITY SHOULD
ALSO REMAIN BELOW SEVERE LIMITS DUE TO WEAK INSTABILITY.
