NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Jul 5, 1:34 PM EST, 4 hours 56 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 234 PM EDT Wed Jul 5 2017 .NEAR TERM /Through Thursday/... Scattered storms have developed on the Gulf coast sea breeze in the Big Bend region to the west and southwest of Gainesville and isolated showers have developed near Baxley and across Marion County. Showers and storms will continue to develop across the interior towards I-75 through the afternoon and into the early evening before dissipating. There is a little more instability aloft compared to yesterday, and some storms could become strong with gusty winds and frequent lightning the main impacts. Temperatures were mainly in the low to mid 90s across the region, and expect heat indices in the 102-108F range to continue this afternoon. Overnight lows will be muggy with temperatures in the 70s. 500mb ridge axis will remain centered a couple hundred miles east of the region through Thursday, with the ridge axis extending across the Florida/Georgia border. The low/mid level ridge axis across north central Florida today will move northward across northeast Florida on Thursday. Models indicate as the ridge shifts northward that drier air will move into north central and portions of northeast Florida on Thursday, with precipitable water values of 1.5 inches or less. This will lead to mainly dry conditions southeast of a line from Gainesville to St. Augustine. The Gulf coast sea breeze will move inland, with scattered showers and storms moving into the Big Bend area after 18Z, with storms pushing inland of the Suwannee River basin around 20-21Z. Isolated to scattered storms are then forecast to develop along I-10 northward between 21-00Z as moisture rotates northeastward from the Gulf. Afternoon temperatures will be hot once again, with highs in the 90s and heat indices of 102-108F. .SHORT TERM....Thu night through Sat... Above normal warmth and below normal rain chances will continue with the 1000-700 mb ridge axis lingering across the forecast area through Fri. The presence of this ridge axis will continue to suppress convective growth and the dry mid level air will limit convective converge of diurnally enhanced sea breeze and airmass triggered thunderstorms. Thu evening sea breeze convection will fade across inland areas, west of Highway 301. On Friday, the surface ridge axis settles farther south as a lee side trough deepens down the Appalachians ahead of an approaching surface front. This pattern transition will bring a stronger west coast sea breeze front across the local area and focus the highest rain chances east of Highway 301 where sea breezes and outflows converge in the late afternoon and evening. Sat deeper moisture settles across SE Georgia in advance of the approaching surface front with rainfall expected increasing in coverage through the day across SE Georgia along this moisture axis. Addition convection will begin to develop along the sea breezes across NE Florida, although expect more limited coverage due to drier air. Once again a stronger west coast sea breeze will focus the strongest convergence west of Highway 301 Saturday afternoon and evening. There is the potential for a few strong to isolated severe storms each afternoon and evening with wet downbursts the primary hazard. Temperatures will trend above normal with highs in the low/mid 90s with heat index values 100-105 degrees. Muggy conditions will continue at night with low temperatures ranging generally in the 70s, although a few inland locations could realize upper 60s Fri and Sat morning. .LONG TERM...Sun through Wed... An extended period of above normal rain chances with moist SW steering flow across the local area between a mean layer trough upstream across the eastern Gulf Coast region and high pressure extending across south Florida. PWAT values range near 1.8 to 2 inches each day with a more dominant west coast sea breeze triggering convection and a weak frontal zone stalling and become diffuse across SE GA through Tue. Late Tue into Wed the Bermuda ridge across the Atlantic begins to retrograde westward over central Florida, which will increase subsidence and lower rain chances back near climo values with flow transition to SSE and a slightly more dominant east coast sea breeze. Temperatures will trend more toward climo values with an increase in cloud cover and precip with max values in the lower 90s and low temperatures above normal in the 70s. && .AVIATION... Prevailing VFR conditions through the period. Storms may develop near KGNV late this afternoon into the evening, and left the VCTS and TEMPO groups. An isolated shower/storm could get near KVQQ, but left out of TAF. East to southeast winds 10 knots will prevail this afternoon, with light and variable winds overnight. && .MARINE... Surface ridge of high pressure will remain just south of our waters, maintaining southerly 10-15 kt winds and 2-4 ft seas through the week. A weak cold front will move into the southeast states late in the weekend. This feature and increased westerly flow aloft may bring higher chance of thunderstorms to area coastal waters Friday through Sunday. Rip Currents: Low risk of rip currents through Thursday. && .PRELIMINARY POINT TEMPS/POPS...
