925 FXUS62 KCAE 021014 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 614 AM EDT Tue Sep 2 2025 .SYNOPSIS... Temperatures warming to near normal through Thursday ahead of a cold front. Front moves through Thursday, expected to be mostly dry. Above average Friday and Saturday before another front moves into the area late this weekend leading to chances for rain into early next week. && .NEAR TERM /THROUGH TONIGHT/... Key Message(s): - Cool, dry weather continues Persistent upper troughing remains in place over the eastern US today. At the surface, dry northeast flow will continue to provide dry weather and cooler than normal temperatures. Highs will again be in the low to mid 80s with lows tonight in the upper 50s to low 60s. Skies will be mostly clear with just thin cirrus and afternoon cumulus. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... Key message(s): - Temperatures warming to near normal as dry weather expected to continue. Upper level ridging over the Atlantic will begin to strengthen while an upper level low will dig into the Great Lakes. That will leave our area with gradually rising 500mb heights for the second half of this week. Blended guidance favors temperatures rising to near average with highs Wednesday mostly in the mid-80s. Moisture still expected to be limited with HREF mean PWATs below 1.2 inches and rising heights leading to a shortwave passing to the north of the forecast area. Lows will also moderate with low temperatures in the low to mid 60s. Thursday, a surface cold front will move into the Ohio Valley with low level warm advection strengthening with highs expected in the mid to upper 80s with a noticeable uptick in humidity. Ensemble means have continued to trend drier with this front with the strongest forcing remaining north of the area. As a result, most of the area is expected to remain dry with near average temperatures. Lows in the mid to upper 60s. && .LONG TERM /FRIDAY THROUGH MONDAY/... Key message(s): - Temperatures rising to above normal by the end of the week into the week. - Slight chance to low chance of showers Sunday and Monday. Consensus among blended guidance is that the front will not push through the forecast area. Limited spread in blended highs through Saturday shows a high confidence that highs will continue to rise to above average with highs into the mid 90s by Saturday ahead of another cold front. Precipitation chances remain low until late in the period when PWATs increase with GEFS probabilities of PWATs greater than 1.5 inches around 60 to 70 percent by Sunday an Monday. With forcing not especially impressive, blended guidance has slight chance to low chance pops Sunday and Monday with isolated to widely scattered showers possible. While some limited instability is possible with around 50% of GEFS members showing greater than or equal to 500 J/kg Sunday and Monday, thunderstorms chances will be low. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... VFR conditions expected through the 24 hour TAF period Northeast flow will continue to support dry weather through the 24 hour TAF period. NE winds around 7 to 10 knots will pick up around 15z but will not be as strong as the previous day. No restrictions are expected with just a few afternoon cumulus and cirrus overhead. Dry air will preclude fog formation tonight. EXTENDED AVIATION OUTLOOK...Restrictions possible on Thursday as moisture increases ahead of a front. A few showers are also possible Thursday. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...None. GA...None. && $$
