In his short-term weather discussion National Weather Service Senior Forecaster John McMichael says another cool front is headed our way. "A frontal trough now across the panhandle sags into the northern peninsula tonight (Wednesday) then into west central Florida on Thursday where it will stall out through Friday as it becomes parallel to the upper level flow." The official seven-day forecast has a lot of moisture in it with rain chances bumping up into the 40 and 50 percent range through the weekend with highs in the 70s and lows in the 50s.
