Area Forecast Discussion National Weather Service Columbia SC 438 AM EDT Sat May 4 2024

SYNOPSIS
Increasing moisture and shortwave energy will lead to active weather for the weekend through early next week with showers and thunderstorms likely. Dry conditions should prevail for mid-week, with a return of showers and storms possible again by Friday. Expect well above normal temperatures each day.

NEAR TERM /THROUGH TONIGHT/
A weak shortwave trough is moving through the Southeast this morning leading to isolated showers and thunderstorms. A second, stronger, shortwave will move into the forecast area this afternoon. With atmospheric moisture well above normal values, we expect numerous showers and thunderstorms to develop leading to widespread rain during the afternoon. Weak, deep layer shear points to pulse type convection and makes organized thunderstorms unlikely. Mean sbCAPE values from the HRRR are around 1000 J/kg, consistent to SREF values from the previous day's forecast. This points to enough instability for scattered thunderstorms but potentially too little for much of a severe threat, particularly considering the lack of dry air available for evaporational cooling. The biggest threat will be localized heavy rain if it occurs in urban or other flood prone areas.
Daytime heating will be hampered by overcast or mostly cloudy skies and rainfall. This will keeps afternoon temps in the 70s to low 80s.

Expect convective activity to diminish in the late evening as the shortwave energy lifts out of the forecast area.
Temperatures will be mild overnight with lows in the 60s.
Abundant low-level moisture should lead to fog or low stratus over the region early Sunday morning.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/
High pressure off shore will keep low-level moisture across the area Sunday and Sunday night. Weak upper shortwave will move through the area, and even with limited instability, scattered showers and thunderstorms are expected to develop through the day. Daytime temperatures will be near normal, with highs in the lower 80s, while overnight lows will be in the middle 60s, which is well above normal.

LONG TERM /MONDAY THROUGH FRIDAY/
Monday into Tuesday will see upper trough passing through the area, with upper ridging then moving in Wednesday into Thursday. A deepening upper trough will then push southward into the region Friday. This pattern generally will bring a period of showers and thunderstorm early in the week, with dry weather then expected during the mid-week timeframe. By Friday, showers and thunderstorms will re-enter the region ahead of the approaching trough. Temperatures are also expected to gradually increase from just above normal on Monday, to well above normal through the end of the week.

AVIATION /08Z SATURDAY THROUGH WEDNESDAY/
Restrictions or thunderstorms likely for much of the TAF period.

Abundant atmospheric moisture will lead to low stratus and/or reduced visibilities this morning, and promote numerous showers and thunderstorms today. Expect IFR/MVFR ceilings for portions of the morning with rainfall chances, and associated restrictions, becoming increasingly likely after 15Z. Periods of reduced visibility from rainfall and thunderstorms should be expected at all TAF sites today. However confidence in the exact timing for each site is too low for TS to be included in the TAFs at the moment.

Expect convective activity to diminish in the late evening.
However low level moisture will remain high which should lead to stratus and fog development again, with restrictions potentially extending to the end of the 24 hr TAF forecast.

EXTENDED AVIATION OUTLOOK...
Fog or stratus possible through at least Monday with abundant low level moisture in place. Convection also likely for Sunday and Monday with restrictions and thunderstorms possible.

CAE WATCHES/WARNINGS/ADVISORIES
SC...None.
GA...None.
