Area Forecast Discussion National Weather Service Columbia SC 750 PM EDT Sat May 4 2024

SYNOPSIS
Showers and thunderstorms have moved into the area and will continue through early next week with showers and thunderstorms possible each day. Dry conditions should prevail for midweek, with a return of showers and storms possible again by Friday.
Expect well above normal temperatures each day.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
Upper impulse will slowly track from northern/central GA ENE across northern/central SC. Latest guidance indicates convective development in the near term over the CSRA, then tracking to the ENE over portions of the central and northern Midlands through the overnight period. Severe threat low due to low DCAPE values, high WBZ heights, minimal deep layer shear and only weak instability. Locally heavy rain possible though due to slow movement and possible training. Lows in the 60's.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/
Sunday and Sunday night: An upper shortwave is forecast to continue trekking eastward through the day Sunday and is expected to be offshore by Sunday night. At the surface, high pressure offshore is expected to drift eastward, but still aid in keeping plenty of moisture in the area, with PWAT values around 1.5". A relative low in shower and thunderstorm activity is forecast due to the shortwave passing to our east. However, a weaker shortwave is anticipated to move through the region, resulting in scattered shower and thunderstorms, particularly in the afternoon. With weaker support, we're not expecting the activity to be as widespread as today or Monday. Temperatures are expected to be near average once again during the day, but relatively warm overnight.

Monday and Monday night: Another shortwave is forecast to move across the area on Monday. This shortwave looks to be a bit more pronounced, leading to an uptick in shower and thunderstorm activity for the day, especially in the afternoon and evening.
The upper air dynamics are anticipated to be similar to today, limiting the severe threat. PWATs are anticipated to increase some again, which could lead to locally heavy rainfall again.

LONG TERM /TUESDAY THROUGH SATURDAY/
The upper shortwave is expected to move out of the area Tuesday, taking the precipitation along with it. That said some scattered showers are possible during the morning before they exit the area. Broad ridging then builds back over the area, which will aid in a midweek warm up. Temperatures are forecast to warm to well above average by Wednesday and Thursday. A larger scale trough is anticipated to move toward and through the region for the end of the week, bringing a cold front along with it. Model guidance does differ in the timing of its passage, which would affect how warm we get on Friday. Regardless of the timing, chances of precipitation returns with this system.

AVIATION /21Z SATURDAY THROUGH THURSDAY/
Variable conditions in showers and thunderstorms with restrictions likely for much of the TAF period.

Showers and a few thunderstorms have mainly been west of the terminals this morning and are now developing across the entire area. Have update the TAFs to include the developing convective activity through the evening hours. Cigs with the showers and thunderstorms will lower to 1 to 1.5 kft with vsbys lowering to 1 to 2SM as showers have been efficient rain producers with rainfall rates around 2 inches per hour. Convection will diminish early tonight however with high amounts of low level moisture expect stratus and fog to continue through the end of the period.

EXTENDED AVIATION OUTLOOK...
Fog and stratus possible through at least Monday with abundant low level moisture in place. Showers and thunderstorms with associated restrictions possible Sunday through Tuesday.

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