Area Forecast Discussion National Weather Service Charleston SC 919 PM EDT Sun Aug 3 2025 .SYNOPSIS... A stationary front will linger in the vicinity of the area through at least the middle of the week. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... No major changes this evening. Convection is slowly waning across the interior, but is beginning to reload over the Atlantic offshore of the lower South Carolina coast where mass convergence persists from northeast winds 15-20 kt. The focus for showers and possibly a few tstms will shift to the Beaufort County to lower Charleston County corridor overnight. Instability will not be overly strong in these areas where deeper wedge conditions are in place. This will tend to temper hourly rainfall rates despite PWATs in excess of 2.25". However, much of this area has observed between 4-7" with isolated 10" amounts over the past 3 days per MRMS analysis. It will not take too much to get at least minor flooding of low-lying and poor drainage areas. While isolated flash flooding can not be ruled out, expect mostly Flood Advisory level flooding given the lack of significant instability. coast. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... Monday through Wednesday: Aloft, the forecast area will be situated ridging to the east and a trough that is expected to slowly advance east of the MS Valley. At the surface, high pressure will continue to hold east of the Appalachians with a stationary boundary to the south across south GA and north FL, as well as the potential for an area of low pressure to develop well off the coast Tuesday into Wednesday. Through the early to mid week time period, the stationary boundary situated to the south should be the main focusing mechanism for shower and thunderstorm development. So while the front will likely meander around a bit, as well as the zone of highest moisture, the highest thunderstorm coverage and best potential for locally heavy rainfall should favor the southern half of the area including southeast GA each day. But, showers and thunderstorms will be possible across the entire area each afternoon and evening given the moist airmass. The severe threat doesn't look particularly noteworthy given the lack of significant instability each day. Temperatures should continue to run below normal for Monday with low to mid 80s, then back closer to normal Tuesday and Wednesday as upper 80s become more common. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... As we head into the late week and into the weekend time period, Atlantic ridging will attempt to build back to the west and into the Southeast. At the surface, model guidance continues to suggest high pressure inland and north, with a subtle boundary situated somewhere along or near the coast. In fact, there could even be weak low pressure development off the coast late in the week that shifts northward through the weekend. We will maintain daily chances of showers and thunderstorms, with some degree of a locally heavy rainfall threat thanks to the presence of plentiful moisture and the aforementioned boundary. Temperatures should gradually trend warmer, back to near normal by the weekend. && .AVIATION /01Z MONDAY THROUGH FRIDAY/... 04/00z TAF Discussion: KCHS/KJZI: Cigs should remain VFR for much of the period. There is a risk that a more concentrated area of showers could push into the terminal just after daybreak and linger through mid- morning. Timing and coverage is somewhat uncertain with the the front still lurking to the south. VCSH was highlighted 10-18z to account for with a TEMPO for MVFR cigs and 6SM in -SHRA. KSAV: Prevailing MVFR will persist for much of the period. A band of showers moving north of the Altamaha River could impact the terminal in the 01-04z time frame. A TEMPO group for MVFR vsbys in -SHRA was highlighted. Another round of showers could impact the terminal just after daybreak and MVFR vsbys were once again introduced in a TEMPO group from 12-15z. Extended Aviation Forecast: Scattered to occasionally numerous showers and thunderstorms will continue to provide the main potential for brief flight restrictions through the middle of the week. && .MARINE... Today and Tonight: A stationary front lies draped slightly north of the FL/GA border with high pressure wedged inland, meanwhile an area of low pressure to the north will continue riding roughly within the northeast flowing Gulf Stream out into the Atlantic. Northeast winds will prevail through tonight in the 10-15 kt range, peaking near 20 kt at times this afternoon. Gusts could approach 25 kt at times, especially this afternoon and evening, but should remain below Small Craft Advisory criteria. Scattered to numerous showers and thunderstorms are likely across the local marine zones this afternoon through most of the night, most of which should be weaker in nature. Seas will average 3-5 feet, before diminishing to 2-4 ft by daybreak Monday. Monday through Friday: Overall, the setup is pretty quiet across the local waters this week with conditions remaining below Small Craft Advisory thresholds. Monday should bring the most elevated winds and seas as northeast flow peaks around 15 knots with gusts up to 20 knots at times. Seas will average 2-4 feet through Monday night. Thereafter, the gradient is expected to relax while winds remain out of the northeast for much of the period (mostly in the 10-15 knot range). Seas should diminish a bit, but still remain 2-3 feet through the week. Rip Currents: Some elevated swell and continued northeast flow will yield a Moderate Risk of rip currents for the GA beaches on Monday. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None.
