573 FXUS62 KTAE 160023 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 825 PM EDT Fri Aug 15 2014 .Near Term [Through Tonight]...
-- Changed Discussion --
The weak quasi-stationary front was still evident across the Tri-state region by the dew point disparity and wind shift. At 00z the boundary was roughly from Alma, Ga southwest to near Panama City. Dew points to the north were in the lower to mid 60s and to the south the lower to mid 70s. As expected, convection today was over the coastal counties and most concentrated across the Southeast Big Bend. All convection has since diminished and PoPs will be trimmed back to 10-20% over coastal areas and will leave 20-40% over the local waters through 12z. Min temps will be in the 60s in our Alabama zones and north of a line from Blakely to Fitzgerald in Georgia with lower 70s elsewhere.

.Short Term [Saturday Through Sunday Night]... Outside of the coastal waters and extreme SE FL Big Bend tomorrow morning, where chance level convection will likely linger from this afternoon`s convective blowup over the NE Gulf of Mexico, the overall trend of dry air intrusion from the NW is expected to continue into this weekend. This should result in generally slight chance to low end chance PoPs over the interior (20-30%) at best, as well as fairly hot high temperatures, which are expected to be on the high side of the middle 90s away from the coast. Although afternoon temps will be about the same on Sunday, it will feel a bit more comfortable on Saturday as dewpoints are expected to mix out into the lower to middle 60s, while on Sunday, the higher humidity will return to the region allowing Heat Indices to exceed the 100 degree mark in most locations. .Long Term [Monday Through Friday]... Nearly zonal flow will gradually be replaced by building upper level ridging across the SE U.S. through the entire extended period, while a weak Sfc high pressure system generally remains in place across the northern Gulf of Mexico. This type of synoptic pattern with potential stacked ridging should result in a prolonged period of hot and humid conditions across the entire CWA, with below normal PoPs forced only by the diurnal sea breeze circulation. High temps should at least be in the mid 90s away from the coast, with some upper 90s certainly possible by mid to late week. Overnight lows will mainly be in the very muggy mid to upper 70s.

&& .Marine... Although winds will generally be light out of the west to southwest at around 10 knots through much of the period with 1 to 2 foot seas across our Coastal Waters, a slight increase in the pressure pattern on Sunday night may allow for a brief spike of 10 to 15 knot winds and 2 to 3 foot seas. Mariners should also be cautious for locally higher winds and seas in scattered showers and thunderstorms for the remainder of this afternoon through tomorrow morning. && .Fire Weather... Despite some drier air than is typical for the summer months, especially in parts of Alabama and Georgia, relative humidity should remain above critical thresholds and red flag conditions are not expected. && .Hydrology... Rainfall totals through Sunday are expected to range from 0.25 to 1.00 inches. With all area rivers below action stage, no flooding is expected. && .Preliminary Point Temps/PoPs...
