Area Forecast Discussion National Weather Service Charleston SC 213 AM EDT Sun Apr 14 2024

SYNOPSIS
High pressure will persist through much of next week. A cold front might impact our area late next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/
Tonight: Quiet weather conditions will prevail through the remainder of the night while high pressure remains centered just south of the local area. Clear skies and light/calm winds in place will lead to strong radiational cooling across southeast South Carolina and southeast Georgia, favoring cooler low temps.
In general, lows should dip into the mid 40s well inland to the upper 50s/near 60 at the beaches and around downtown Charleston.

SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/
Zonal flow aloft on Sunday will transition to upper ridging Monday into Tuesday. Meanwhile the surface high over the Southeast will move off the coast on Sunday. Mostly clear skies are expected Sunday through Monday, then some high cirrus spreads in from the west on Tuesday.

Highs will reach the low to mid 80s on Sunday, then mid to upper 80s Monday and Tuesday. Lows will be in the upper 50s to lower 60s.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
Zonal flow expected mid to late week with weak surface high pressure over the western Atlantic. A few vort maxima embedded in the mean flow will move through during the period, with weak surface cold fronts approaching from the west, then dissipating.
A stronger front may approach on Friday, but even this one may not make it all the way through the area. Temps will remain well above normal through the period.

AVIATION /06Z SUNDAY THROUGH THURSDAY/
VFR conditions will prevail at KCHS/KJZI/KSAV terminals through 06Z Monday.

Extended Aviation Outlook: VFR.

MARINE
Tonight: Quiet conditions will prevail across local waters while the pressure gradient steadily relaxes in response to high pressure building east along the northern Gulf of Mexico. In general, west winds will peak no higher than 10 kt across all waters. Seas will be no higher than 2-3 ft.

Sunday through Thursday: Quiet marine conditions expected Sunday through the end of next week. Atlantic high pressure will prevail, with S to SW winds 10-15 kt and seas no higher than 4 ft. A decent sea breeze will develop each afternoon, with winds in Charleston Harbor occasionally gusting close to 20 kt.
