122 FXUS62 KCAE 040233 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 1033 PM EDT Thu Jul 3 2025 .SYNOPSIS... Weak front moves east, bringing slightly drier air through the latter portion of the week. Isolated showers and storms possible through Friday as a weak surface boundary sits over the area. Deeper moisture may return to the region this weekend leading to increased rain chances which will continue through much of the long term. && .NEAR TERM /UNTIL 7 AM FRIDAY MORNING/... Key Message(s): - A few showers possible through midnight, then partly cloudy and mild. The very slow moving and diffuse front continues to inch closer to the coast. A few weak showers are popping up from time to time this evening, but this will generally wind down by midnight. There are some higher level clouds pushing across the area from the west, with the HREF suggesting an increase in coverage through the night. With this in mind, overnight lows will be mild but seasonal, generally in the low to mid 70s. && .SHORT TERM /7 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... Key Message(s): - Isolated showers and storms - Expect above normal temperatures for Independence Day A weak surface boundary will remain draped over the area becoming increasingly diffuse through the short term. PWAT values remain around 1.25 inches across the Upstate and western Midlands with deeper moisture closer to the coast. This suppress convective development each afternoon. While isolated coverage is still expected, the greater rain chances will be restricted to along the coast. Temperatures for Friday will be slightly above normal with mostly clear skies. Highs should be in the mid 90s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Key Message(s): - Moisture returns to the region in the long term Global models continue to be persistent developing weak low pressure offshore along the stalled surface boundary. The favored zone of development is off the Atlantic Coast from northern FL to NC. There remains a good deal in uncertainty in the track of the low which will largely determine our weather through most of the long term. At this point there is some potential for strong moisture advection into the Southeast bringing widespread rain but there are also ensemble members that keep us completely dry through the period. && .AVIATION /03Z FRIDAY THROUGH TUESDAY/... VFR Conditions Expected through the Overnight.... Most of the showers from earlier today have dissipated with VFR conditions at all terminals. Expect scattered mainly high-level clouds and light or calm winds through the overnight period. Guidance has backed off on the restrictions at OGB later tonight, so the TEMPO has been removed from the forecast. Winds increase on Friday and may be breezy at times in the afternoon. Otherwise, an isolated shower or thunderstorm is possible near the end of the current TAF period. Omitted thunder from the forecasts for this update due to low confidence in direct impacts. EXTENDED AVIATION OUTLOOK... There is then the possibility of diurnally driven showers and thunderstorms this weekend into early next week with the potential for periodic restrictions. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...None. GA...None. && $$
