092 FXUS62 KCAE 030022 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 822 PM EDT Thu May 2 2024 .SYNOPSIS...
-- Changed Discussion --
High pressure along the Southeast coast will be in control of the weather across the region tonight. Once again there will be the potential for some patchy fog and stratus during the early morning and sunrise hours on Friday. The area of high pressure will be moving away from the area on Friday allowing for more moisture to move into the region. Warm conditions expected to continue for Friday before rain chances steadily increase late Friday evening into Saturday. Deep moisture convergence coinciding with an upper level trough will drive widespread showers and isolated thunderstorms Saturday. Lingering moisture and little changes aloft will yield further shower-storm chances Sunday through Wednesday.

&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
Fair. Isolated showers have dissipated with loss of heating. Some increase in high level clouds possible late tonight, but otherwise similar regime to previous days, with possibility of late night fog/stratus developing, mainly over the southern half of the forecast area where dewpoints are higher.

&& .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
-- Changed Discussion --
After some patchy fog Friday morning, a generally dry and warm day is expected, at least into the afternoon, as an upper ridge remains overhead and a high pressure sits just offshore. The upper ridge is forecast to stay generally in place through the short term; however, a shortwave disturbance is expected to move through the region. This feature brings increasing chances for showers and some isolated thunderstorms beginning Friday afternoon to the upper CSRA and gradually spreading eastward overnight and into Saturday. Some stronger moisture convergence on Saturday brings higher chances for more widespread showers and embedded thunderstorms to the area, but severe weather is not likely due to a general lack of sufficient instability and wind shear. With extensive cloud cover and more widespread showers, temperatures Saturday are expected to be closer to average or a little below average.

&& .LONG TERM /SUNDAY THROUGH THURSDAY/... A summer-like pattern is expected to remain over the area for much of the long term as the upper ridge stays generally in place. A series of shortwaves moving through the broader flow brings unsettled weather through midweek, with daily chances for showers and embedded thunderstorms. The pattern begins to settle down for the latter portions of the week ahead, with afternoon highs expected to be well above average at the end of the long term period. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --
VFR conditions through the most of the period with restrictions expected during the early morning and sunrise hours. High pressure along the coast this evening will gradually move offshore later tonight and into Friday. The radar shows a nice sea breeze moving northwest this evening. This will produce a brief period of winds from the south-southeast along with a few cumulus. Later this evening cumulus will diminish however with the low level moisture remaining high. Expect some fog and stratus to again develop during the early morning and sunrise hours. Have included mention of MVFR fog at CAE/CUB/DNL/OGB with IFR/LIFR at AGS. Expect the fog and stratus to mix out around 13z with the remainder of the period VFR. Winds from 13z through the end of the period will be southerly around 5 to 7 knots. EXTENDED AVIATION OUTLOOK... Late night/early morning fog possible through the period. Increased potential for showers and thunderstorms Friday evening through Tuesday.
