Area Forecast Discussion National Weather Service Jacksonville FL 848 AM EDT Tue Jul 11 2017 .UPDATE...Winds will be light onshore today allowing the east coast seabreeze to move well inland...merging late day with the west coast seabreeze near the I-75 corridor. PWATs are still near 2 inches over most of the area and with light steering winds the main threat from storms will be locally heavy rainfall. Frequent lightning strikes and strong gusty winds will also occur especially where cell mergers occur. Drier air aloft from the east will move into our se zones so coverage of storms should be less there today. Temperatures will reach the low 90s inland with heat indices near 100 this afternoon. && .AVIATION...VFR conditions this morning. Scattered showers possible late morning/early afternoon near the east coast...and scattered to numerous thunderstorms inland by mid to late afternoon. Have VCSH and VCTS in forecast...may be upgrade to TEMPO thunder for VQQ and GNV after 18z. && .MARINE...Light and variable winds over the waters this morning will become southeast at 10 knots this afternoon and tonight.
