SYNOPSIS
High pressure will prevail through much of next week. A weak cold front could approach late next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Late this evening: Aloft, the upper ridge axis will continue to shift eastward and should be aligned up the Eastern Seaboard by sunrise. At the surface, high pressure centered near the New England coast will remain the primary feature, with some hints of a coastal trough just offshore. The rest of the overnight is expected to be dry, though we will periodically see offshore showers push toward the coast and dissipate. These showers are developing within narrow corridors of convergence noted in visible satellite imagery, but they have consistently weakened once they get within about 20 miles of shore. We do not expected to see another round of fog and stratus again tonight.
Overnight lows should range in the upper 50s to low 60s in most areas, though portions of the coast might not fall out of the mid 60s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/
Aloft, a strong mid-upper lvl ridge will remain directly over the Southeast United States this weekend, then shift offshore early next week. At the sfc, the local area will remain along the southern periphery of cool high pressure centered to the north while subtle coastal troughing takes place off the Southeast Coast. The setup will favor onshore flow each day, with sfc winds slowly veering during the weekend and resulting in a slight warming trend as the ridge aloft starts to slide offshore early next week. Latest guidance continues to suggest low-lvl flow bringing sufficient moisture onshore in the form of scattered/broken stratocumulus Saturday morning and potentially Sunday morning. High temps should peak into the upper 70s/lower 80s away from the coast this weekend, then low-mid 80s away from the beaches on Monday. Overnight lows should range in the upper 50s inland to mid 60s near the beaches Saturday night and Sunday night. However, lows could be dip into the mid 50s well inland Sunday night due to lighter winds and clear skies leading to more favorable radiational cooling conditions.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Mainly dry weather is expected through much of next week as a zonal flow develops across the Southeast by mid-week while sfc high pressure centered across the western Atlantic extends across the Southeast. Warm air advection and ample sunshine will yield a warming trend through the week, with high temps peaking in the upper 80s to lower 90s mid to late week. The next chance of rainfall should come with a front potentially reaching the local area next weekend.

AVIATION /02Z SATURDAY THROUGH WEDNESDAY/
VFR conditions are expected to prevail at KCHS, KJZI, and KSAV through 00z Sunday. We do not expect to see another round of fog and stratus again tonight, though a few clouds in the 1-2 kft range could push onshore at times. Winds will remain elevated within the easterly flow through the evening, then diminish a bit late. By mid morning, east to southeast winds will pick back up with frequent gusts up to around 20 knots expected as early as midday.

Extended Aviation Outlook: Prevailing VFR conditions.

MARINE
Tonight: East winds around 15 kt will hold through the night.
Seas build under the persistent easterly flow and long fetch building to 3-5 ft and possibly as high as 6 ft late overnight and through much of the upcoming weekend in the Georgia offshore leg out 20-60 NM. We will be hoisting a Small Craft Advisory for that offshore leg starting at 4 AM early Saturday morning and continuing through Sunday afternoon.

Saturday through Tuesday: High pressure centered well north of the region will favor a long east-northeast fetch across local waters this weekend, and support seas building up to 6-7 ft across offshore Georgia waters, where a Small Craft Advisory remains in effect until late Sunday afternoon. Otherwise, marine conditions remain fairly quiet across remaining coastal waters with east-northeast winds peaking near 15-20 kt on Saturday slowly veering to south-southeast during the weekend and weakening to 10-15 kt or less early next week.

Rip Currents: Moderate onshore winds will continue through the weekend, while approximately 3 ft waves every 6-7 seconds reach the beaches. The local rip current calculator indicates a Moderate Risk of rip currents along all beaches Saturday, then lingering along the Georgia beaches Sunday.

CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...Small Craft Advisory from 4 AM Saturday to 6 PM EDT Sunday for AMZ374.
