161 FXUS62 KCAE 241704 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 104 PM EDT Sun Aug 24 2025 .SYNOPSIS... Overall drier weather expected today as the deepest moisture moves away from the region, but isolated showers are possible around the periphery of the forecast area. Cooler air pushes into the region on Tuesday through the remainder of the forecast period. Dry weather expected through much of the week with a chance of rain returning late week into the weekend. && .NEAR TERM /THROUGH TONIGHT/... Key Message(s): - Incredible weather expected this afternoon A coastal low is currently moving northeastward off the coastline of NC ahead of a deepening trough across the eastern US. Northerly flow is present across our forecast area, with widespread dewpoints in the 60s as a result. Temps are in the low 80s pretty much at all sites and skies are mostly sunny. All in all, what an incredible day it is out there! Moisture will likely increase slightly over this evening as the big time front begins approaching from the northwest but should only result in some other clouds. Lows tonight should be elevated given the approaching front with lows in the upper 60s and low 70s. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Key message(s): - A cold frontal passage on Mon will bring cooler weather Tue An upper level trough digs into the eastern US in the short term. The associated cold front will push through the forecast area on Monday. With limited moisture ahead of the front, rainfall is unlikely. The HREF indicates potential for convection along the coast of Monday afternoon where moisture is deeper but CAMs show very little or no coverage in the forecast area. Cooler and drier air will filter into the region as high pressure builds in behind the front. Overnight lows will be cooler than the previous night in the mid to upper 60s. Tuesday will be noticeably cooler and less humid than our normal August conditions. Dewpoints will drop into the 50s with highs in the mid 80s to give us fall-like weather. Lows overnight will be in the lower to mid 60s. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Key message(s): - Dry weather and cooler than normal temperatures expected Little change to the long term forecast. A dry, cool air mass will remain in place through much of the extended as the region sits under the influence of persistent upper troughing and N/NE low level flow. Cool temperatures expected for the week with highs mainly in the low to mid 80s and lows in the 60s. NAEFS ESAT shows temperatures and PWATs at or below the 10th percentile in the climatological database through much of this period indicating low precip chances. Easterly flow may develop near the end of the long term ushering moisture back into the forecast area. This supports at least a slight chance of rain for Friday and Saturday. && .AVIATION /16Z SUNDAY THROUGH THURSDAY/... Generally VFR through the TAF period. Beautiful conditions have developed this afternoon and this is expected to continue through the period. Skies are clear right now and this is expected to remain the case this afternoon. Dewpoints have fallen as have PWs, and the results should be a cloudless afternoon. There may be few or scattered clouds that develop this evening but in general the skies are forecast to remain clear for a lot of this TAF period. Look for winds to shift from VRB to more consistently northwest tomorrow as the front approaches and passes the forecast area. EXTENDED AVIATION OUTLOOK...A drier air mass will arrive behind a cold front, likely putting an end to widespread restrictions. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...None. GA...None. && $$
