Area Forecast Discussion National Weather Service Charleston SC 311 PM EDT Fri Apr 18 2025

SYNOPSIS
High pressure will persist into early next week. A front could push into the region by the middle of next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Surface high pressure off the coast of NC/VA will continue to slowly move eastwards, with upper level ridging strengthening into the overnight period. This will continue the observed quiet and warm conditions, with afternoon highs still expected to reach up into the lower to mid 80s inland, with areas along the coast in the mid to upper 70s. The breezy winds behind the sea-breeze will be subsiding near-sunset, along with the cu field dissipating around the same time.

As the inversion sets up during the evening hours, the region becomes decoupled allowing for winds to further decrease into the overnight hours. With clear skies, radiational cooling will allow for temperatures to drop down to near dewpoint temperatures, in the mid 50s inland and lower 60s along the coast. Similar to the past couple mornings, some patchy fog in low-lying areas near sunrise is possible (up to 20% probability) highest across inland southeastern Georgia counties. Due to the patchy nature and low probabilities, have left mention out of the forecast.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/
An impressive deep-layered subtropical anticyclone will extend across the Southeast U.S. for much of the period, slowly sliding offshore by Monday. This will result in a regime dominated by strong synoptic scale subsidence which is well represented by strong capping inversions noted on regional model soundings. With the center of the Bermuda high progged to remain well offshore, expect modest to locally strong resultant sea breeze circulations to form each afternoon and move steadily inland before decaying during the early evening hours while exiting into the Midlands, CSRA and east- central Georgia. Highs each afternoon will range from the mid-upper 80s inland with lower 70s at the beaches. Lows both Sunday and Monday mornings were trended slightly cooler than the 18/13z NBM guidance with full boundary layer decoupling likely to occur each night away from the coast. Lows will range from the the upper 50s/lower 60s with upper 60s at the beaches and Downtown Charleston.
Varying degrees of high clouds will stream across the region, especially Sunday into Monday. Some shallow cumulus humilis is also possible each afternoon ahead of the sea breeze.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
High pressure off the Southeast U.S. will gradually weaken into the middle of next week as the subtropical anticyclone aloft begins to breakdown and the resulting flow across the southern states becomes more zonal. A cold front will attempt to drop into the region Wednesday. It is unclear how far south the front will get given the boundary will become increasingly parallel with the flow aloft. Rain chances will build by mid-week as the front draws closer with signals that there may be some sea breeze/frontal interactions. Pops were increased to 20-40% based on the latest NBM, but again, much depends on how far south the front gets before retreating back to the north Thursday into Friday. Above normal temperatures will persist.



AVIATION /19Z FRIDAY THROUGH WEDNESDAY/
The sea-breeze is pushing inland, with semi-breezy winds behind it gusting into the teens to lower 20s. Otherwise, VFR and quiet conditions are expected to continue into the overnight period. Similar to the past couple mornings, some patchy fog in low-lying areas near sunrise is possible (up to 20%) highest across inland southeastern Georgia counties, not looking to impact the TAF sites at this times.

Extended Aviation Outlook: Gusty winds are possible each afternoon at all terminals with the passage of the sea breeze. There are no other concerns.

MARINE
Tonight: Surface high pressure off the coast of NC/VA will continue to keep conditions mostly quiet across the region, with winds remaining out of the southeast. The wind will remain on the semi- breezy side with gusts into the teens, possibly lower 20s as evident by Shutes Folly and Beaufort obs, through the early overnight hours but should remain below small craft criteria. The winds will subside after midnight into the morning hours on Saturday.

Saturday through Wednesday: A southerly flow regime with afternoon sea breeze enhancements in the Charleston Harbor and along the land/sea interface will persist into the middle of next week. Winds will generally remain less than 15 kt with seas 2-4 ft.
