Area forecast discussion, Aug 29, 3:14 PM EDT, 11 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 314 PM EDT Wed Aug 29 2018 .NEAR TERM [Through Tonight]... Local radars show convection increasing rapidly across the Florida panhandle and Big Bend early this afternoon. Also, additional showers and thunderstorms from the east coast sea breeze are approaching from the Suwannee Valley. Looks like a very active remainder of this afternoon with the HRRR showing convection continuing at least into late evening much like we saw yesterday. Likely PoPs across the Big Bend and portions of the panhandle until 06z with chance PoPs elsewhere. Lows in the lower to mid 70s. .SHORT TERM [Thursday Through Friday Night]... Through the end of this week, the persistent ridge of high pressure that has been residing just east of the mid-Atlantic states will continue to produce moist east and southeasterly flow. This will keep scattered showers and thunderstorms in the forecast each afternoon along with enhanced coverage along the Gulf and Atlantic seabreezes as they move north and west respectively. Meanwhile, during the early morning hours coverage of showers and thunderstorms will be more likely over our coastal waters. .LONG TERM [Saturday Through Wednesday]... The synoptic pattern for the rest of the forecast period will remain very similar. The aforementioned ridge of high pressure will continue to produce large scale easterly and southeasterly flow. This setup will allow for increased rainfall chances slightly- above normal and temperatures at or slightly below seasonal levels due to enhanced cloud coverage. The NHC is currently monitoring a tropical disturbance located near the Lesser Antilles. This system will move northwest towards the Bahamas for the next few days. && .AVIATION [Through 18Z Thursday]... Scattered to numerous showers and thunderstorms are developing across the area early this afternoon. With such widespread coverage, most or all terminals can expect at least brief impacts from a TSTM this afternoon/evening. After storms diminish later this evening, VFR conditions will prevail until at least 09z when patchy IFR-MVFR cigs/vsbys will be possible overnight. && .MARINE... East and southeast winds around 10 knots along with seas around 1 to 2 feet is expected today and tonight. Winds pick up slightly through the rest of the week and into the weekend with winds ranging from 10 to 15 knots and seas increasing to around 2 to 3 feet. Expect scattered to widespread showers and thunderstorms through the next week with most activity tied to the morning and early hours. && .FIRE WEATHER... Low dispersions less than 20 are possible tomorrow afternoon. Patchy fog is possible in the early morning hours. && .HYDROLOGY... The active convective pattern will continue through the period with increased chances of showers and thunderstorms expected over the CWA during the afternoon hours. Although widespread precipitation is not expected, given the current moist regime slow moving moving storms with high rain rates could cause localized flooding in low- lying and poor-drainage areas. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
