821 FXUS62 KCAE 090151 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 951 PM EDT Wed Oct 8 2025 .SYNOPSIS... Drier air pushes in overnight behind the cold front with gusty northeast winds expected. Cooler, drier and breezy during the day both Thursday and into Friday behind the cold front. Coastal low develops this weekend with continued breezy conditions but mostly dry weather expected. && .NEAR TERM /UNTIL 7 AM THURSDAY MORNING/... Key message(s): - Cooler/drier air begins to work in behind the cold front overnight. - Lake Wind Advisory beginning at 2am tonight. The cold front is pushing through the FA this evening as a batch of rain remains in southern Bamberg and Orangeburg Counties, just ahead of it. GOES PWAT`s show drier air moving in behind this front where they quickly fall under 1.5" in the northern FA and toward 1.25" in the upstate. This drier air will continue to filter in tonight, largely bringing rain chances to an end between Midnight and 3am. Cold advection will also push in as flow turns out of the northeast, allowing overnight lows to fall into the mid to upper 50s in the north and the upper 50s to near 60 in the south. This push of CAA, a tightening surface pressure gradient behind the front, and a developing 30-40 kt LLJ overnight, should bring gusty northeast winds after 2am, continuing into Thursday morning. Gusts around 25-30 mph are expected, though isolated gusts to 35 mph will be possible over area lakes and thus a Lake Wind Advisory remains in effect starting at 2am tonight, continuing into Thursday morning. && .SHORT TERM /7 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... Key message(s): - Cooler, drier, and breezier. Well the cold front will be pushing south and east by Thursday morning, and taking those warmer temperatures along with it. Behind it, there will be a somewhat noticeable drop in temperatures each day through the short term and high pressure setting up north of the region funnels colder air southward east of the Appalachians. Cold advection will dominate, and afternoon high temperatures will only reach 70 to 75 on Thursday, then the lower 70s on Friday. Lows will be in the 50s through the period. The front will be off the coast Thursday, with enough dry air in place to keep the entire forecast area rain free. By Friday, a low off the southeast coast will begin to slowly organized, and some moisture will moving inland across the coastal plain. Can not rule out an isolated shower over extreme eastern Midlands through the afternoon, with the remainder of the area staying dry. The other issue both days will be the strong and breezy winds behind the front Thursday, and as the coastal low starts to organize on Friday. These will keep the pressure gradient tight enough to bring the potential for stronger wind gusts, especially on area lakes, both through the daytime hours and overnight on Thursday night. The fetch across the lakes is not ideal, but the strength of the low-level jet overnight combined strong cold advection over the warm water temperatures should allow for at least some mixing over the lake Thursday night. A Lake Wind Advisory will be in effect until 11 am on Friday. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Key message(s): - Coastal low moves up the coast over the weekend - Breezy conditions continue over the weekend - Generally dry with seasonal temperatures Surface low gets better organized on Saturday along the Carolina coastlines, but will at least be tracking away from our area through the day. Still expect some gusty winds during the day, although not as strong as previous few days. With moisture moving inland through Saturday, isolated to scattered light showers can not be ruled out during the day over the eastern and northeastern counties. By Sunday a return to drier conditions will occur as the low will be moving away and high pressure setting back in across the area. Temperatures should remain near to below normal with a slight warming trend early next week. && .AVIATION /02Z THURSDAY THROUGH MONDAY/... Gusty winds up to 25 knots tonight into Thursday afternoon. A cold front will move across the terminals overnight. The front has been slower to move into the Carolinas than expected. This had led to light winds this evening and gave enough time for shallow fog to develop at AGS after having received some light rain earlier. Winds will pick up out of the N/NNE after the front passes between now and 08Z. Skies will also clear through the night as drier air moves into the region. Early Thursday morning, cold advection strengthens behind the front and NE winds around 10 kts are expected at all terminals. Wind gusts will be around 20 kts from early Thursday morning until the afternoon when they will taper off some. With much drier air over the region, no convection is expected. EXTENDED AVIATION OUTLOOK...Dry conditions and predominantly VFR conditions are expected to continue through the extended. Gusty NE winds are expected again Thursday night and Friday. && .CAE WATCHES/WARNINGS/ADVISORIES...
