733 FXUS62 KCAE 050625 AFDCAE Area Forecast Discussion National Weather Service Columbia SC 225 AM EDT Wed Jun 5 2024 .SYNOPSIS... Moisture increases across the Southeast through mid week leading to scattered convection each afternoon. A cold front will move across the Southeast Thursday increasing chances for showers and thunderstorms. Drier air follows the front late this week into the weekend. && .NEAR TERM /UNTIL 7 AM THIS MORNING/... Widespread convection from earlier this afternoon has stabilized the majority of the forecast area, with some instability left across the CSRA and far western midlands where storms didn`t really develop earlier today. Storms have picked up intensity a bit across this area in the past hour or so as a weakly organized line of convection approaches ahead of a remnant MCV/shortwave from previous convection across the lower MS Valley. Expecting some of these showers/storms to remain in tact as we head into the overnight hours tonight, but they should slowly weaken and diminish in coverage and intensity. Cloud cover will likely hang around for much or all of the night, and with moisture rich low-levels, expect lows to only fall into the upper 60s to around 70. && .SHORT TERM /7 AM THIS MORNING THROUGH THURSDAY NIGHT/... A few isolated showers or thunderstorms may still linger Wednesday morning, but the activity is expected to increase as we head into the afternoon as another shortwave disturbance moves across the region. Expect coverage to be similar or even higher than today as PWATs are expected to be around 1.75" Wednesday afternoon. Activity is anticipated to wane overnight ahead of another round of showers and thunderstorms on Thursday. A cold front moving toward the region will aid in keeping the PWATs elevated ahead of it, allowing scattered showers and storms again in the afternoon and evening. The severe threat for both days is minimal; however, a few of the stronger cells could produce wind gusts of 40 to 45 mph, especially on Thursday. The cold front is anticipated to move through the region late Thursday night/early Friday morning. && .LONG TERM /FRIDAY THROUGH TUESDAY/... After the front passes, drier air is expected to move in behind it. That said there could be an isolated shower or storm over the eastern portions of the forecast area on Friday, depending on exactly where the front is located. Otherwise, dry conditions are expected for the weekend ahead of more activity possible early for the week ahead. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... VFR conditions generally expected over the 24 hr forecast period outside of showers or thunderstorms and possible morning stratus. Diminishing showers continue to slowly move through the region early this morning and may impact the terminals but not expecting restrictions in rainfall as it remains light. Cigs also remain VFR in the 5kft to 12kft range. Some stratus already developing in the Upstate and north GA with NBM and LAMP guidance suggesting this stratus will build eastward but uncertain if it will make it to the terminals or not. Decided to include a tempo for MVFR cigs around 1500 ft from 09z-13z with possible IFR vsbys in fog at AGS where recent rain may enhance fog threat, despite a 20 knot low level jet. Otherwise, expect another day similar to yesterday with afternoon scattered convection developing across the region with southwesterly winds picking up to around 7 to 10 knots and widespread cumulus clouds prior to convective initiation. EXTENDED AVIATION OUTLOOK...Scattered afternoon and evening showers and thunderstorms through Friday with intermittent CIG/VSBY restrictions possible. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...None. GA...None. && $$
