Area Forecast Discussion National Weather Service Jacksonville FL 419 PM EDT Sun Jun 17 2018 .SHORT TERM...Tonight and Monday...East coast seabreeze moving inland across ne Fl this afternoon. Drier air aloft has reduced the coverage of storms today. A cloudy start today over se Ga delayed the seabreeze and formation of convection there...with storms now forming as outflows from previous storms are acting on increasing instability. Best coverage of storms will be over western zones this afternoon/evening as the seabreeze continues westward. A deepening easterly flow on Monday with drier air aloft advecting to the east coast will mean scattered convection over inland areas west of I-95. Near average temperatures will continue. Monday night through Wednesday night...High pressure at the surface and aloft will maintain a deep easterly flow on Monday. East coast sea breeze will move well inland with best afternoon rain chances near the I-75 corridor where the seabreeze merger and higher moisture values will be located. Surface ridge will shift to the south with a light low level sw flow developing for Tuesday and Wednesday. This will result in hotter temperatures near the east coast as the seabreeze will be slower to move inland. Drier air aloft near the east coast will result in lower rain chances near the coast with scattered p.m. storms again expected over inland areas Tuesday and Wednesday. Slow cell motions will lead to areas of locally heavy rainfall. Above normal temperatures are expected. .LONG TERM...Thursday through Sunday...Mid and upper level ridge will be situated across the area through the period. Surface ridge will be south of the area with a trough across the Carolinas and Georgia which will provide a sw low level flow and hot temperatures. Daily high temperatures are expected to be in the mid 90s over inland areas with heat indices near 105. Ample moisture (PWATs near 2") will remain under the ridge for daily convection. Light winds will result in seabreezes moving inland where the best coverage of storms will occur. && .AVIATION...Predominantly VFR conditions through tonight. Scattered thunderstorms will continue to develop inland this afternoon producing locally IFR conditions and gusty winds. Storms expected to dissipate later this evening with a chance of patchy fog early Monday morning reducing visibilities. && .MARINE...High pressure to the north will continue the east to southeast winds through Monday. Surface ridge pushes south of the area by midweek resulting in an offshore flow pattern again interrupted by daily seabreezes. Low wind speeds and sea heights are expected over the next few days. Rip Currents: Moderate risk on Monday due to onshore winds persisting. && .PRELIMINARY POINT TEMPS/POPS...
