LOCALLY HEAVY RAINFALL AND GUSTY WINDS MAY RESULT. OTHERWISE...REST OF THE CWA SHOULD BE SPARED FROM CONVECTION AS THE FRONTAL BOUNDARY OVER THE CWA IS BECOMING MORE DIFFUSE AND IN THE ABSENCE OF A LARGER SCALE LIFTING MECHANISM. OF NOTE IS THE FACT THAT SOME CLEARING IS ALREADY TAKING PLACE...AND THIS INCREASES THE CONCERN FOR FOG FORMATION OVERNIGHT. IF CLOUDS FROM THE WEAKENING QLCS TO THE WEST DON/T MOVE IN OVERNIGHT...THEN THERE MAY BE SOME AREAS OF DENSE FOG ESPECIALLY THOSE LOCATIONS THAT PICKED UP RAIN. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...

STRONG STORMS MAY BE POSSIBLE THURSDAY AFTERNOON AND EVENING BUT WILL DEPEND LARGELY ON THE IMPACT OF CLOUD COVER FROM THE DAY BEFORE ON INSTABILITY. HIGH PRESSURE WILL BUILD INTO THE AREA BEHIND THE COLD FRONT FOR THE MAJORITY OF THE WEEKEND...BEFORE ANOTHER FRONTAL SYSTEM APPROACHES FROM THE WEST ONCE AGAIN INCREASING THE CHANCES OF SHOWERS AND THUNDERSTORMS INTO EARLY NEXT WEEK. && .AVIATION /04Z WEDNESDAY THROUGH SUNDAY/... RISK OF TSRA HAS ENDED ACROSS THE TERMINALS FOR THE OVERNIGHT. GIVEN CLEARING WHICH IS TAKING PLACE...AM BECOMING INCREASINGLY CONCERNED FOR FOG OVERNIGHT.
