Area Forecast Discussion National Weather Service Columbia SC 757 PM EDT Fri Apr 19 2024

SYNOPSIS
Moisture increases into Saturday as a cold front moves toward the area. With strong heating each afternoon, diurnally driven isolated showers and thunderstorms are anticipated to develop.
The front becomes stationary near or slightly south of the area Sunday. Deep moisture and lift across the area will result in numerous showers Sunday and Sunday night. Temperatures Sunday and Monday are expected to be well below normal.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Isolated convection, mainly across eastern areas, indicating a weakening trend. Some convection just NE of the FA drifting SE could hang on across the NE FA this evening and early tonight.
Some guidance indicating some showers could develop along a sea breeze boundary across the southern FA later tonight. Lows in the lower to mid 60s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/
Although a surface front will be moving southward through the area, much of Saturday has been trending drier through the daytime hours. Some warming aloft and weak lift should inhibit any rain through the early afternoon. By late afternoon into the evening, warming aloft may weaken enough to trigger isolated to scattered showers/storms, especially over the eastern cwa and the coastal plain where moisture may be better. Moving into Saturday night, upper flow out of the southwest will bring Gulf moisture over the surface front. In addition, an area of low pressure moving along the surface front will push towards the area from the west overnight. This will bring additional moisture along with it into Sunday. Region will see increasing rain chances overnight Saturday into Sunday morning. For Sunday, more widespread stratiform rainfall is expected to overspread the area as a surface wedge moves in from the north.

Temperatures Saturday will vary a bit from north to south as the front sags southward. Northern counties will remain in the 70s, while the southern CSRA will reach the mid to upper 80s. Sunday will be a much different day across the entire forecast area as much cooler air moves in on northeasterly winds. Additional cooling from the expected rainfall and cloud cover, and the warmest temperatures may actually occur early in the day, with steady or falling temperatures possible through the day.

LONG TERM /MONDAY THROUGH FRIDAY/
Rainfall should be rapidly moving out of the area by Monday morning, bringing a return of drier weather for the remainder of the week. Do expect low-level wedge flow to continue bringing cooler temperatures across the area on Monday, with afternoon highs well below normal once again. Still, with some sunshine possible, readings will be a little warmer than Sunday's highs as readings are expected in the middle 60s.

As mentioned, Tuesday through Thursday will be dry. Another weak front may move through the region towards the end of the forecast period, but moisture remains limited. After the cool temperatures of Monday, the region will see a moderating trend to the afternoon highs and overnight lows.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/
VFR conditions through the TAF period.

Isolated showers north of CAE/CUB are weakening and will remain north of the terminals. Overnight expect little change with some cirrus clouds beginning to drift over the area. Change will begin during the early afternoon hours as moisture begins to increase across AGS/DNL/OGB as a weak boundary moves into the region. Showers and thunderstorms are expected to begin developing in the late afternoon and early evening hours however confidence remains too low to include mention attm. Winds will subside to variable at 4 knots or less by 02z then become northerly around 7 knots from 14z through the end of the period.

EXTENDED AVIATION OUTLOOK...Increasing confidence in restrictions Sunday into Monday with possible developing wedge conditions.
