Area forecast discussion, Aug 4, 9:35 AM EDT, 5 hours 27 minutes before
Area Forecast Discussion National Weather Service Jacksonville FL 935 AM EDT THU AUG 4 2016 .UPDATE... No change to previous forecast as Morning Soundings still show Precipitable Water levels just above 2 inches in the moist Southwest Flow and expect numerous coverage of showers and storms this afternoon for all areas. Diurnal heating NE of the current showers over inland NE FL will support Max Temps in the lower 90s with a few mid 90s possible in areas that don't receive rainfall until later in the day. Main threat from activity will be heavy rainfall with localized/temporary minor flooding issues. The stronger storms will still produce some frequent lightning and gusty winds but still expecting mostly below severe limits as Mid level temps at 500mb still showing warm conds with temps at -4C to -6C range. The SW steering flow is still weak at 5-10 knots and will allow for a weak East Coast Sea Breeze to develop and push inland to about the I-95 corridor, so most of the activity will be over inland areas through the afternoon, although activity along the I-95 corridor will drift towards the coast during the late afternoon and evening hours with just enough SW steering flow to get them there. Most of the activity will wind down during the evening hours around sunset, although the atmosphere will remain moist enough to support isolated showers at any time through the night. Muggy overnight lows in the 70s expected. && .AVIATION... Still VFR this AM, but high rain chances this afternoon will need tempo groups for all Inland TAF sites as IFR Vsbys and MVFR Cigs appear likely. Coastal TAF sites may escape some of the storms as the SW steering flow may be weak enough to keep activity just inland. Gusty winds up to 25-30 knots possible along with reduced VSBYS due to heavy rainfall for brief periods. && .MARINE... Light SW Flow 10-15 knots becoming SE later today along the coast. Seas 2-4 ft nearshore and 3-5 ft offshore. No headlines. Main impacts will be storms near the coast with gusty winds and heavy rainfall and lightning. Rip Currents: Moderate Risk with morning breaker reports of 2-3 ft with the occasional 4 ft surf. && .PRELIMINARY POINT TEMPS/POPS... AMG 94 75 91 74 / 60 60 60 30 SSI 91 77 88 76 / 60 60 60 40 JAX 93 75 90 75 / 70 60 70 40 SGJ 93 76 87 76 / 60 60 60 40 GNV 92 73 88 74 / 70 60 70 50 OCF 92 74 88 74 / 70 60 70 60 && .JAX Watches/Warnings/Advisories...
