752 FXUS62 KCAE 071046 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 646 AM EDT Fri Jun 7 2024 .SYNOPSIS... Drier air will move in behind a cold front today and into the weekend. Another cold front will move through the area and stall along the coast early next week. This will result in scattered diurnally driven showers and thunderstorms through mid week. Temperatures will be near or above normal. && .NEAR TERM /THROUGH TONIGHT/... The axis of an upper level trough will shift east today with a cold front continuing east of the forecast area with drier air behind it. The airmass behind the front is not much cooler but we will see dewpoints drop into the 50s. NW or WNW low-level downslope flow will lead to increased adiabatic heating and lower RH values than they would otherwise be. Highs today will be in the upper 80s to low 90s with clear or mostly clear skies. Winds will be breezy behind the front with gusts from 15 to 20 mph possible. Temps tonight will be slightly cooler than the past few days in the low to mid 60s. A 20 kt LLJ will prevent ideal radiational cooling tonight and limit the threat of fog formation. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... Not really much change in the forecast for the early part of the weekend. High pressure will keep conditions dry through Saturday night. Winds out of the west along with plenty of sunshine will keep afternoon high temperatures in the low to mid 90s for most of the forecast area. && .LONG TERM /SUNDAY THROUGH THURSDAY/... A cold front will be situated north of the cwa on Sunday, slowly tracking southward towards the area through the day. Region will see more of a downsloping flow pattern ahead of this front through the day Sunday, and this will have the affect of bringing some of the warmest afternoon temperature readings to the region in quite a while. Afternoon highs in the mid to upper 90s should occur. The downsloping winds will also help to keep much of Sunday dry, with moisture still rather limited. The surface front is expected to move across the cwa Sunday night into Monday morning, with some moisture increase along the front. This will bring at least scattered showers to the northern half of the Midlands overnight, while the southern half of the cwa will remain dry. Overnight lows will be in the upper 60s to lower 70s Sunday night. The front moves south and east Monday before stalling out close to the coast for the remainder of the forecast period. Moisture will remain along and near the front, and with weak energy moving along the front each day, expect that the region will see more of a summerlike pattern as scattered mainly diurnally driven showers and thunderstorms develop each day. Temperatures should be near or above normal. && .AVIATION /12Z FRIDAY THROUGH TUESDAY/... VFR conditions expected through the 24 hour TAF period. A cold front will continue east today with dry air following and breezy NW winds. VAD wind profile from KCAE shows a 20 kt LLJ which will mix down over the next few hours picking up winds at the surface. Restrictions are unlikely because the dry air will hinder any fog/stratus development and prevent convection in the afternoon. During the day expect mostly clear skies with NW winds gusting up to 20 kts. Another 20 kt LLJ tonight will also limit the fog threat, keeping VFR conditions in place. EXTENDED AVIATION OUTLOOK...Moisture increases early next week which may lead to early morning fog or stratus and diurnal convection. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...None. GA...None. && $$
