ISOLATED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS THE SOUTHERN ZONES IN AN AXIS OF INSTABILITY WHERE THERE IS VERY WEAK FORCING. APPEARS THAT THIS ACTIVITY WILL CONTINUE TO SAG SOUTH THROUGH THE REST OF THE AFTERNOON AND THEN DISSIPATE WITH THE LOSS OF HEATING. SKIES WILL THEN CLEAR OUT. MOS LOOKS REASONABLE FOR LOW TEMPERATURES. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/... MODELS INDICATING THAT A WEAK TROUGH WILL LINGER IN THE SOUTHERN ZONES. SOUNDINGS SHOW SOME MID LEVEL CAPPING. WITH ONLY WEAK FORCING THIS MAY BE ENOUGH TO SUPPRESS ANY CONVECTION. BUT CANNOT RULE OUT A FEW STORMS IN THE AFTERNOON.

STAYED WITHIN A FEW DEGREES OF MOS FOR TEMPERATURES. && .LONG TERM /SUNDAY THROUGH FRIDAY/... THE LONG TERM WL START OUT DRY ACROSS THE FA.
