SYNOPSIS
High pressure will prevail through much of next week. A weak cold front could approach late next week.
NEAR TERM /UNTIL 6 AM THIS MORNING/
Dry conditions prevail as the surface high ridges in more strongly from the north. Mainly cirrus sky cover, with more low clouds - based around 3-4 kft - likely to develop through the overnight hours, abating radiational cooling and suppressing the potential for radiational fog. Latest trends suggest temps to dip into the upper 50s far inland, but remain in the mid-upper 60s at the beaches where a light onshore flow prevails.
SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/
A quiet weather pattern is expected through the short term period, owing to broad ridging will prevailing aloft and high pressure dominating at the surface. As the week progresses the ridging aloft will slowly shift off the southeastern coastline. A shortwave trough is expected to ripple across the southeastern states Tuesday into Wednesday, possibly spurring some showers/tstorms across far inland locations.
Between the ridging aloft and the high pressure dominating at the surface temperatures through the middle of the week will be above normal, reaching into the low to mid 80s each day. Overnight lows are forecast to dip into the 50s Sunday night with 60s Monday night.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
Weak ridging will build back in aloft, while high pressure continues to prevail at the surface. Another shortwave trough is forecast to swing across the southeastern states Friday, bringing the region the next chance of precipitation. Otherwise, quiet conditions with above normal temperatures are expected.
AVIATION /05Z SUNDAY THROUGH THURSDAY/
VFR conditions are expected to prevail at KCHS, KJZI, and KSAV through 00Z Monday.
Persistent BL moisture will bring the potential for increasing low level clouds with peak cooling late tonight, and some patchy MVFR to IFR stratus/stratocu could develop before sunrise.
Guidance indicates greatest moisture pooling south of the Charleston area, so just TEMPO MVFR cigs at SAV for the time being, with CHS and JZI more likely to be sct below 3kft.
Improved mixing increases cloud bases after sunrise.
Extended Aviation Outlook: Prevailing VFR.
MARINE
Overnight: Sfc high pressure centered north of the region will continue to sag south across the local area, slackening the pressure gradient across coastal waters. Expect east-southeast winds no higher than 10-15 kt, but with the favorable onshore fetch, seas could build another foot or so. A Small Craft Advisory will remain in effect across offshore Georgia waters through the night, mainly for seas up to 6-7 ft. Seas will remain below advisory levels across nearshore waters, generally in the 3-5 ft range.
Sunday through Wednesday: With high pressure prevailing aloft, generally quiet marine conditions are expected through the middle of the week. Seas will subside across the 20 to 60 nm offshore GA waters Sunday afternoon/evening and the Small Craft Advisory will expire. Thereafter seas will average 2 to 4 ft across the marine zones. Winds will be out of the SE to SW, generally around 10 knots.
Each afternoon a sea breeze is expected to form each afternoon which could produce some gusty winds along the coastline and in the Charleston Harbor. Some gusts could approach 20 knots.
Rip Currents: Moderate onshore winds will continue through the weekend, while approximately 2 or 3 ft waves every 7-8 seconds reach the beaches. The local rip current calculator indicates a Moderate Risk of rip currents along all beaches through tomorrow (Sunday).
CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...Small Craft Advisory until 6 PM EDT this evening for AMZ374.
