.DISCUSSION...

A DEEP TROUGH OF LOW PRESSURE CENTERED OFF THE COAST WILL SEND
A COUPLE OF WEAK DISTURBANCES INTO THE REGION FROM THE SOUTH THIS
AFTERNOON AND EVENING. THE APPROACH OF THESE FEATURES COMBINED
WITH WARM SURFACE TEMPERATURES WILL TRIGGER ISOLATED THUNDERSTORMS.
DRIER AIR WILL TEMPORARILY MOVE OVER THE FIRE ON WEDNESDAY AND END
THE THREAT OF THUNDERSTORMS. THE TROUGH WILL BEGIN TO SHIFT INLAND
BY THURSDAY AND SHOULD BE FIRMLY ENTRENCHED OVER THE FIRE BY THE
WEEKEND. THIS WILL RESULT IN A SIGNIFICANT COOLING TREND WITH
INCREASING CHANCES FOR PRECIPITATION. BREEZY SOUTHWEST WINDS THURSDAY.
