Tonight-Wed...A high pressure located over the northeast Gulf of Mexico this afternoon will be extending eastward tonight. With that, winds will veer from the north to the east tonight into Wednesday as the high pressure moves towards the western Atlantic. Dry conditions will remain over land although a few showers could be possible over the local Atlantic waters on Wednesday as patches of moderate moisture reach the area. Skies will remain mostly clear tonight with some low clouds moving toward the coast on Wednesday as the aforementioned moisture moves in. Temperatures will be a few degrees warmer tonight but still dropping to the upper 40s for rural locations across the interior and lower 50s elsewhere. And a few degrees warmer too for Wednesday with highs in the mid-upper 70s.

Wednesday Night-Saturday... Zonal flow aloft will yield to a fast and weak moving shortwave that will sweep through region Wednesday night into Thursday. The longwave pattern will attempt to become meridional as the trough deepens southeastward across eastern CONUS. However, the southern branch of the upper-level jet will quickly outrun the trough causing it to quickly pivot northeast as ridging builds upstream of east-central Florida. With the lack of of upper-level support and sufficient moisture with precipitable water values remaining around or below 1, only isolated showers are expected over the local Atlantic waters. Weak high pressure will build over the Gulf and slowly move eastward through the beginning of the weekend. Persistent zonal flow will lead to a continued pattern of mostly dry conditions with weak fast moving disturbances lacking support and moisture to produce decent chances for rain. Highs will remain in the low 70s to low 80s with lows in the upper 40s to low 60s. Another weak trough will then move into the region by the end of the weekend as high pressure breaks down over Florida.

Saturday-Monday (previous discussion)... Aforementioned mid level troughs moves slowly east across GA/NOFL this weekend, with its vort signature becoming strong out across the peninsula Mon, as a larger, broad trough deepens over the eastern CONUS. At the surface, the ridge over FL slowly weakens As a weak inverted trough develops along or near the FL east coast. thereafter, a cold front, is forecast to slow and become W-E oriented as it reaches NOFL late Monday or Monday night. Model guidance has backed off on shower chances, now showing just a small coastal shower chance Sun...but dry otherwise. Temps remain near to slightly above normal, with highs in the 70s and mins in the 50s.

Marine
Tonight...High pressure over the southeast U.S. will keep the local winds light and gentle tonight shifting from the NE. Seas 3-4 ft.
