Area forecast discussion, Jul 5, 2:31 PM EDT, 3 hours 42 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 231 PM EDT Wed Jul 5 2017 .NEAR TERM [Through Tonight]... Isolated to scattered convection remains possible this afternoon along the sea breeze across the panhandle and big bend with a few storms also possible in portions of south central Georgia. Activity will dissipate rapidly around sunset with overnight low mainly in the middle 70s. .SHORT TERM [Thursday Through Friday Night]... A surface ridge axis will be aligned east-west over or just south of the area through the period. The deep layer dry air evident on today's water vapor imagery will remain in place as well, keeping PW below seasonal levels and helping to suppress convective coverage. Therefore, PoPs will be below normal and temps will remain above normal. A front will approach from the northwest on Friday, slightly increasing PoPs across our northwest zones. While overall convective coverage will be below normal, dry air aloft will support some stronger wind gusts in any storms that do form each afternoon. .LONG TERM [Saturday Through Wednesday]... A weak upper level trough will be over the region for most of this period with the surface ridge axis south of the area. A front will slip into the area over the weekend and then dissipate. These features will result in PoPs returning to more seasonal levels (40- 50%). Daytime highs will be in the lower 90s with overnight lows in the lower to mid 70s. && .AVIATION [Through 18Z Thursday]... [Through 18z Thursday] VFR conditions are expected to prevail. Isolated to scattered convection is possible near ECP, TLH, and VLD this afternoon, but the chance appears too low to mention anything in the TAF at this time. && .MARINE... Light winds and seas are expected to prevail through the period outside of any showers and thunderstorms. && .FIRE WEATHER... Dispersion indices may be high Thursday afternoon for parts of southwest Georgia. There are no other fire weather concerns. && .HYDROLOGY... Shower and thunderstorm activity will remain isolated to scattered in nature for the next couple of days, increasing somewhat for the weekend and early next week. There will be minimal changes for flooding and area rivers and streams will remain below flood stage. && .PRELIMINARY POINT TEMPS/POPS...
