RADAR TRENDS SHOW LIGHT SHOWERY PRECIPITATION OVER THE COASTAL WATERS. THIS ACTIVITY WILL INCREASE INLAND THROUGH THE AFTERNOON AS SURFACE HEATING AND BOUNDARY INTERACTIONS CREATE ADDITIONAL CONVECTIVE ACTIVITY ACROSS THE CENTRAL AND THE WESTERN PENINSULA. SCATTERED SHOWER/STORM CELLS LATER THIS AFTERNOON...ESPECIALLY INTO THE INTERIOR MAY CONTAIN LOCALLY HEAVY RAINFALL...FREQUENT CLOUD TO GROUND LIGHTNING AND GUSTY WINDS. CELL MOTION WILL BE TOWARD THE SOUTHWEST OR SOUTH. ELEVATED NORTHEAST WINDS FROM THIS AFTERNOON WILL FALL BACK TO 5 TO 10 MPH THIS EVENING. OVERNIGHT LOWS WILL FALL BACK INTO THE 70S. MON-TUE...LOCATION/STRENGTH OF TROUGHING ALONG THE EAST COAST WILL PLAY A FACTOR IN PRECIPITATION CHANCES THESE TWO DAYS.
