SYNOPSIS
High pressure will prevail through much of the week. A weak disturbance will move through Tuesday and Wednesday, then a weak cold front will stall in the vicinity this weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
Late this evening: Overall, the rest of overnight is expected to be quiet as the area remains under the influence of high pressure parked over the Atlantic. Cirrus could start to increase late tonight ahead of an approaching shortwave, but for the most part we should see mostly clear skies. Model guidance indicates the potential for a corridor of showers to develop offshore within an area of weak convergence, mainly late tonight closer to sunrise Tuesday. But none of this is expected to impact land areas. Lows are forecast to range from the upper 50s inland to the low 60s along the coast.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/
An upper shortwave will pass across the region Tuesday into Tuesday night and provide a bit more active weather than recent days. The first half of Tuesday is expected to be mostly dry then there will be an uptick in convective coverage as we move into the afternoon and persisting through the evening and the overnight. Less coverage is expected on Wednesday as the upper wave shifts offshore, but a surface trough lingering in the vicinity could still trigger isolated to perhaps scattered showers and thunderstorms. High temperatures generally peak in the mid 80s inland of the beaches, while lows stay in the 60s.

Ridge builds over the region on Thursday which will act to limit rain chances. It will be the warmest day of the set, with highs reaching the upper 80s to near 90 away from the immediate coast.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
Mid level ridge extending across the region on Friday will slide east over the weekend as a weakening shortwave moves in.
The surface pattern largely features high pressure although a weak surface trough will linger in the area. These features will support low-end rain chances (generally 20-30%) over the weekend, with the highest coverage inland.

AVIATION /03Z TUESDAY THROUGH SATURDAY/
VFR conditions are expected to prevail at KCHS, KJZI, and KSAV through 00z Wednesday. We could see stratocumulus spread onshore Tuesday morning, potentially producing a period of VFR ceilings.
Otherwise, attention turns to the shower and thunderstorm potential Tuesday afternoon and evening. Through the end of the 00z TAF period, the best chances of showers and thunderstorms should be along or west of KSAV. If a shower or storm were to reach KSAV, it would be in the last couple hours of the TAF period. Therefore we have kept any mention of impacts out of this TAF issuance.

Extended Aviation Outlook: Prevailing VFR.

MARINE
Tonight: High pressure centered across the western Atlantic will extend across the region, maintaining quiet marine conditions across local waters. In general, winds will remain at or below 10-15 kt, slightly veering to south-southeast overnight. Seas will range between 2-4 ft, largest across offshore Georgia waters.

Tuesday through Saturday: Atlantic high pressure will remain the dominant feature Tuesday through Saturday, with winds generally no higher than 10-15 kt and seas 2-4 ft. A moderate coastal sea breeze will develop each afternoon.

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