Area Forecast Discussion National Weather Service Tallahassee FL 322 PM EDT Tue Sep 18 2018 .NEAR TERM [Through Tonight]... Deep layer ridging is in place over the eastern Gulf waters and the FL Peninsula, with a trough pushing eastward off the mid- Atlantic coastline. This is producing mostly west- northwesterly flow over the tri-state area. The movement of the trough aloft, combined with our diurnal seabreeze circulation is enhancing development of showers and thunderstorms somewhat this afternoon. Later, with the loss of daytime heating, storms over lad will wind down within a few hours of sunset and overnight convection will be focused over our offshore waters. Temperatures are currently making their peak in the low-mid 90s and will cool overnight into the low-mid 70s. Patchy fog will be possible in south central GA in the early morning hours. .SHORT TERM [Wednesday Through Thursday Night]... The upper ridge over the Southern Plains will build steadily eastward to a position over the Carolinas by 12Z Friday. At the surface, a surface trough will be dissipating over the area with a ridge to the north. Offshore flow will keep sea-breeze induced showers and storms confined to areas south of U.S. 84. This will lead to another hotter than normal day with highs across inland areas in the lower to mid 90s and heat indices around 100. By Thursday, the surface high will push off the Mid Atlantic Coast with low level winds veering to easterly. Subsidence underneath the upper ridge will suppress activity across our GA zones with chance PoPs further south and west. Temperatures will be a degree or two lower than on Wednesday. .LONG TERM [Friday Through Tuesday]... Deep-layer ridging to the northeast and subsidence ahead of an approaching TUTT will keep convection relatively suppressed through Friday and Saturday. After that time, the TUTT will move west and deep layer flow will become southerly. This will increase our PoPs to around 40% from Sunday into early next week. && .AVIATION [Through 18Z Wednesday]... VFR conditions should prevail through the period at most sites with the brief possible exceptions of thunderstorms this afternoon across the area and patchy (<20% coverage) MVFR vsbys around sunrise near VLD. Winds will be light. && .MARINE... Winds will be light for the beginning of the period shifting from southwesterly on Tuesday and Wednesday to an easterly regime from Thursday through the weekend. During this latter period, nightly surges of winds up to 15 knots will be possible. && .FIRE WEATHER... With light winds and RH values above critical thresholds, Red Flag Conditions are not expected through the next few days. Scattered thunderstorms are possible each afternoon as well. && .HYDROLOGY... Flooding will not be a concern over the next several days. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
