AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 130 Pm Edt Sun Mar 8 2026
Synopsis -
atlantic high pressure will continue to extend its axis westward across the florida peninsula, creating a prevailing south to southwesterly wind flow across our local waters through midweek. A frontal boundary entering the southeastern states this afternoon will stall to the north of our waters tonight before lifting northward as a warm front on Monday night and Tuesday. Showers and Thunderstorms developing this afternoon along the interstate 95 corridor will likely progress eastward across our local waters late this afternoon through early this evening, with activity likely dissipating by midnight. Otherwise, episodes of dense fog will be possible each morning through midweek.
a stronger cold front will cross our local waters on Thursday, accompanied by showers and possibly a few stronger Thunderstorms. Strong northwesterly winds in the wake of this frontal passage will create small craft advisory conditions on Thursday afternoon, with these conditions continuing on Thursday night and Friday morning as high pressure briefly builds over the mid-atlantic states. Winds will quickly shift to northerly and then northeasterly on Thursday night before becoming easterly with diminishing speeds on Friday afternoon.

Area Forecast Discussion National Weather Service Charleston SC 747 PM EDT Sun Mar 8 2026
WHAT HAS CHANGED
The thunderstorm risk has ended for today and Key Message 1 has been removed. The Aviation section has been updated for the 00z TAF issuance.
KEY MESSAGES
- 1) Unseasonably warm temperatures continue through Wednesday, along with increased rain chances.
- 2) A cold front may bring widespread rainfall on Thursday in addition to breezy conditions.
DISCUSSION
KEY MESSAGE 1: Unseasonably warm temperatures continue through Wednesday, along with increased rain chances.
The mid-levels will consist of zonal flow overhead Monday.
Ridging builds over the Deep South Tuesday, then shifts over the Southeast U.S. on Wednesday. At the surface, a stalling/dissipating front will be to our northwest on Monday, while High pressure is in the western Atlantic. The High will prevail in this location through Wednesday. This pattern will usher moisture into our area through the middle of next week.
NBM POPs should be slight chance late Monday, then increasing to chance POPs Tuesday. Any showers/thunderstorms during this time period are expected to be fast moving, leading to low rainfall amounts. No severe weather is expected.
Unseasonably warm temperatures will continue through Wednesday.
Highs will range from near 80 degrees to the upper 80s, except cooler temperatures along/near the coast. Wednesday should be the hottest day across our entire area with a few spots across our interior GA counties making a run for the 90 degree mark.
Lows each night will generally be in the upper 50s to lower 60s.
KEY MESSAGE 2: A cold front may bring widespread rainfall on Thursday in addition to breezy conditions.
The mid-levels will consist of a trough quickly moving over the East Coast early Thursday, then offshore from the late afternoon into the overnight hours. At the surface, a cold front, will quickly move from west to east through our area, during the morning or afternoon, shifting offshore during the evening and overnight hours. There will be a deep plume of moisture ahead of this front. The combination of the moisture and lift may generate widespread showers across our area.
Though, due to the fast movement, rainfall amounts look to remain on the lighter side at under 0.5". Given the unseasonably warm temperatures ahead of the front, there should be just enough instability to fire off some thunderstorms. But the risk of severe weather is low given the unfavorable (early) timing of the front. Additionally, expect breezy southerly winds ahead of the front. Winds will clock around to the west/northwest behind it and increase due to cold air advection and building strong High pressure.
The High will bring dry conditions for the end of the week.
High temperatures will be a few degrees above normal on Friday, then well above normal on Saturday.
AVIATION /00Z MONDAY THROUGH FRIDAY/
The 00z TAF period begins with VFR conditions at KCHS, KJZI, and KSAV. There could still be a period of showers moving through KCHS and KJZI through about 03z, but not significant impacts are expected. Fog and stratus will be a concern again tonight, with the low ceilings likely being the main driver of flight categories. The main time period of concern is roughly from 08-13z for IFR conditions at all 3 TAF sites. Stratus and any fog should lift by around 14z and VFR will return. As of now, little to no shower and thunderstorm activity is expected Monday afternoon and evening.
Extended Aviation Outlook: Flight restrictions are possible each night and morning through midweek due to low stratus/fog.
Brief flight restrictions are possible due to showers and thunderstorms on Tuesday. A cold front should bring flight restrictions and breezy conditions on Thursday.
MARINE
Tonight: Southerly winds will generally range between 10-15 kt through the period. Some gusts to 20 kt are possible across nearshore SC waters as well. Seas will remain in the 2-4 ft range nearshore and up to 4-5 ft across offshore Georgia waters. Another round of patchy to areas of fog is expected to develop across the nearshore waters late tonight. There is potential for dense fog to develop, but there are concerns that afternoon and evening shower and thunderstorm activity could disrupt the fog environment. Confidence in the development of dense fog is considerably less than the last few nights.
Extended Marine: High pressure will be the dominant weather feature across our local waters through the middle of this week.
Expect south/southwest wind sustained in the 5-10 kt range and seas 2-4 ft. A cold front will approach from the west late Wednesday, causing winds and seas to increase to Small Craft Advisory levels across all of our ocean zones. The cold front should cross through our waters Thursday, causing winds to veer behind it and further increase. Gusts to gale force are possible across portions of our waters Thursday and Thursday night. High pressure building into the region will lead to improving conditions for the end of the week.
