&& .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/... THE SFC HIGH SHIFTS OFFSHORE TONIGHT WITH SW FLOW DEVELOPING...ALTHOUGH IT SEEMS UNLIKELY THAT THESE WINDS WOULD MIX DOWN TO THE SFC ANYWHERE BUT ALONG THE IMMEDIATE COAST OVERNIGHT.

WE BEGIN THE PERIOD WITH HIGH PRESSURE OFFSHORE AND A COLD FRONT APPROACHING FROM THE GREAT LAKES. A MILD SOUTHERLY FLOW IN ADVANCE OF THE FRONT WILL PRODUCE AN UNSEASONABLY WARM DAY SUNDAY. WE`LL SEE AN INCREASING CHANCE FOR SHOWERS AS WE HEAD THROUGH THE DAY SUNDAY...WITH A CHANCE FOR LINGERING SHOWERS BEHIND THE FRONT ACROSS THE HIGHER TERRAIN ON MONDAY. ANOTHER COLD FRONT CROSSES THE AREA ON TUESDAY WITH THE COOLEST AIR OF THE UPCOMING WEEK TO ARRIVE FOR THE MIDWEEK PERIOD.
