Area Forecast Discussion National Weather Service Charleston SC 731 PM EDT Fri Jun 4 2021 .SYNOPSIS... Atlantic high pressure will prevail through late next week. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... The intersection with the sea breeze and a number of convective outflow boundaries has generated a line of numerous showers and tstms from Hampton County east to eastern Berkeley County at 04/2140z. This activity will continue to march east and will likely impact the coastal corridor from Beaufort County through Charleston County over the next 1-3 hours. Farther to the south, across Southeast Georgia, the atmosphere is more stable with cumulus showing signs of dissipating. Adjusted near term pops to increase them to 60-70% in the Beaufort-Charleston corridor. An isolated strong to severe tstm can not be completely ruled out, but with DCAPES already diminishing, the risk is lowering with time. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/... Aloft, a weak ridge will prevail across the region while a trough is centered across the South Central United States. At the sfc, a southerly flow will be in place along the western periphery of Atlantic high pressure and to the east of weak troughing positioned inland. The overall pattern will set the stage for showers and thunderstorms each day, generally peaking in coverage during maximum daytime heating as weak mid-lvl disturbances ripple across the area aloft and a sea breeze shifts inland. Scattered to numerous showers/thunderstorms are possible away from the coast where the combination of moisture and forcing mechanisms are most co-located. High temps will range in the mid-upper 80s each day, with a few locations touching 90 degrees away from the coast in southeast Georgia over the weekend. Overnight lows will remain mild, generally ranging in the upper 60-lower 70s inland to mid 70s near the coast. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... Aloft, a ridge will gradually strengthen while remaining centered across the Southeast United States while a trough weakens across the South Central United States. At the sfc, the area will initially be positioned along the western periphery of Atlantic high pressure, before building further inland during the week. Given the setup, a slight warming trend is anticipated while convective coverage becomes less throughout the week due to the building ridge. Greatest shower/thunderstorm activity should occur well inland Monday afternoon when moisture is largest (PWATs ~2.0 inches), before most activity becomes focused to afternoon sea breeze circulations shifting inland each day. High temps should range in the mid/upper 80s early week, then upper 80s to lower 90s during the second half of the week. Overnight lows should range in the mid 60s-lower 70s inland to mid 70s near the coast. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... Tstms will exit the KCHS and KJZI terminals by 01 and remain in the vicinity of KSAV through the same time. Will include a TEMPO for 1SM +TSRA at KJZI as the heaviest storms may be right at the terminal at 00z. Otherwise, VFR. Scattered tstms will be possible again tomorrow afternoon, but impact probabilities are too low to include a mention at any of the terminals with this TAF cycle. Extended Aviation Outlook: Brief flight restrictions are possible due to low clouds during overnight periods and low vsbys during afternoon showers/thunderstorms each day. && .MARINE... S to SW winds 10-15 kt expected through tonight. Fairly quiet marine conditions will be in place this weekend and through the middle of next week as the region remains along the western periphery of Atlantic high pressure and to the east of weak mid-lvl disturbances passing inland. Outside of shower and thunderstorm activity each day/night, southerly flow will be in place with wind speeds generally 10-15 kt or less. Seas will range between 2-4 ft, highest across offshore Georgia waters. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. MARINE...None. &&
