&& .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
-- Changed Discussion --
Surface high pressure and the upper level ridge will be over the region Wednesday morning then begin moving away from the region during the afternoon as the next cold front approaches from the west. Cold front will move into the forecast area late Wednesday night into the sunrise hours Thursday morning along with a chance of showers. By late morning the cold front will be moving offshore with cold advection overtaking the area. Strong pressure gradient Thursday into Thursday night combined with the cold air advection will result in strong and gusty winds across the forecast area with a lake wind advisory becoming more likely. High temperatures Wednesday will be in the low 70s and fall into the low 60s Thursday...with overnight lows in the low to mid 50s Wednesday night and the mid 30s Thursday night.

&& .LONG TERM /FRIDAY THROUGH TUESDAY/... Little change for the long term forecast as relatively quiet weather is expected to persist. High pressure ridge will be in control of the southeastern states through much of the long term with the main strom track just north of the forecast area. This will keep temperatures below normal with dry conditions as cold air mass remains over the eastern CONUS. && .AVIATION /23Z TUESDAY THROUGH SUNDAY/...
-- Changed Discussion --
High confidence in VFR conditions through the 24-hr TAF period. An upper ridge axis will continue to move over the region from the west tonight through Wednesday morning. The pressure gradient will continue to weaken and winds will become light and out of the west overnight. Fog is not expected to develop due to drier air near the surface. Flow will pick up from the southwest late Wednesday morning with a few cirrus invading from the west ahead of the next system. EXTENDED AVIATION OUTLOOK... There will be chance of showers with associated restrictions Wednesday night and Thursday as a cold front crosses the area. Gusty west-southwest winds with sustained speeds of 15 to 20 kts can also be expected with this frontal passage.
