Area Forecast Discussion National Weather Service Charleston SC 856 PM EDT Sun Apr 14 2024

SYNOPSIS
High pressure will persist much of this week. A cold front might impact the area late in the week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/
No major changes were made for the late evening update. Cirrus associated with a passing impulse aloft will spread over the area through the night. The bulk of the thickest cirrus looks to impact parts of Southeast Georgia. Expect partly cloudy to mostly cloudy skies to prevail. Most of the cirrus should exit offshore by daybreak. The boundary layer has decoupled in a few spots this evening, but the surface pressure gradient is forecast to tighten overnight as a lee-side trough to the north sharpens a bit. This should keep a few knots of wind going.
Lows from the upper 50s well inland to lower- mid 60s at the beaches and Downtown Charleston look on track. The boundary layer may decouple enough in the Hinesville-Darien-Ludowici- Glennville corridor to support an area of mid 50s. This assumes the thickest cirrus exits off the coast several hours before the diurnal minimum.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/
Deep layered ridging expected during the period, though the upper ridge will slightly weaken on Wednesday. Dry weather and well above-normal temperatures expected. Sunny skies on Monday will give way to extensive high clouds Tuesday into Wednesday.
Highs Monday and Tuesday will push into the upper 80s away from the coast, while Wednesday is mainly in the middle 80s.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
A zonal flow will remain in place through Saturday, with mainly dry weather and above normal temps. A weak dry cold front may drop into the area on Friday. Highs on Friday could be the highest of any day this week due to compressional heating ahead of the front. A few spots could touch 90 degrees. Otherwise, highs will be in the upper 80s through Saturday, then slightly cooler on Sunday.

AVIATION /01Z MONDAY THROUGH FRIDAY/
15/00z TAF Discussion: KCHS/KJZI/KSAV: VFR through 16/00z Tuesday.

Extended Aviation Outlook: VFR.

MARINE
Tonight: Atlantic high pressure will be in control as a broad trough remains inland over parts of the east and southeast states. There's a enough of a gradient between these two features, plus 15-20 kt of wind at 925 mb to result in mostly S-SW winds of 10-15 kt and a little gusty over all waters. Seas of just 1-2 feet early on will build about a foot through the night.

Monday through Friday: High pressure will persist over the western and central Atlantic Monday through Thursday, maintaining persistent S to SW flow over the local waters. Winds will generally be less than 15 kt, though we could see a slight enhancement in the late afternoons along the coast due to the sea breeze. Wind directions become a bit chaotic on Friday as a weak cold front drops into the area, then likely dissipates.

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