- Potential for Dense Fog Tonight

- Extended Period of Breezy Onshore Winds This Week. Elevated Surf and High Risk for Rip Currents Likely by Tuesday and

- Record High Temperatures Later This Week

NEAR TERM /THROUGH TONIGHT/

WEATHER CONCERNS THROUGH TONIGHT:

- Dense fog potential Tonight

High pressure will strengthen to the north through Tonight, with a trough developing over the coastal waters. Low level moisture is expected to result in fog and stratus development again overnight.

Temperatures will be near seasonal levels Tonight.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/

Main Highlights During the Period:

- Breezy Winds along the coast - Slight Chance of Coastal Showers Tuesday

Breezy northeast winds develop on Monday as high pressure located north of the area shifts towards the Atlantic, pushing a backdoor cold front towards the area. Along the coast, winds will begin to increase through the day on Monday, peaking during the afternoon hours with gusts from 20 to 25 mph. By the overnight hours, high pressure shifts further into the Atlantic, allowing for winds to wane a bit. Fog development on Monday night likely will be limited due to winds and cloud cover. By Tuesday, the a onshore flow will bring isolated to scattered coastal showers by the afternoon to early evening hours.

Warm temperatures on Monday/Tuesday as daytime highs reach into the upper 70s to lower 80s along inland locations, while the onshore flow will keep coastal locations relatively cooler with highs only reaching upper 60s to lower 70s. Overnight Lows in the lower to mid 50s over SE GA, while mid to upper 50s over NE FL and coastal locations, with some spots reaching into the lower 60s.

LONG TERM /WEDNESDAY THROUGH SUNDAY/

Main Weather Highlights:

- Chances for coastal showers continue Wednesday - Record High Temperatures possible Thursday through the Weekend - Isolated Thunderstorms Inland Thursday/Friday

Onshore flow will persist through much of the upcoming week, allowing for moisture to push inland by the later part of the upcoming week as winds shift to be southeasterly. With the increase in moisture (PWATs ~1.25),isolated to scattered chances of showers across much of the area. With temperatures trending to rise above seasonal averages, could additionally see isolated storms develop during the afternoon hours during the back half of the week, particularly along locations in NE FL. Periods of sea fog will also be possible due to the warm, moist air moving over the cool coastal waters.

AVIATION /18Z SUNDAY THROUGH 18Z MONDAY/

Stratus is expected to move down the coastal waters, and affect KSSI, KJAX, KCRG and KSGJ TAF sites early this period with possible restrictions. Otherwise, VFR conditions for this afternoon and evening. Fog is expected to develop over the area again Tonight, with restrictions expected. This fog will lift during the morning Monday.

MARINE

High pressure will strengthen to the north northeast through Monday, as a coastal trough develops over the coastal waters. The high will move more toward the northeast Tuesday and Wednesday, with the coastal trough gradually weakening. The high will be centered to the east northeast Thursday into the weekend, with the ridge extending across forecast area.

Rip Currents: Moderate risk of rip currents expected at area beaches with some persistent onshore flow and surf height around 2 to 4 feet. Rip current risk increases throughout Monday as onshore flow strengthens.

FIRE WEATHER

- Patchy High Dispersions Monday, Tuesday

A pattern shift with strong upper ridge building across the region this week will lead to near record temperatures Thursday and Friday. Critical weather conditions don't appear to align through the next week but the transition to moist, and mildly unstable, airmass later this week may lead to a moderate sea breeze and the potential for scattered showers and isolated thunderstorms for inland districts Thursday and Friday.

FOG POTENTIAL AND OTHER REMARKS: Potential for locally dense fog Tonight for inland areas, more so across SE GA. Nightly potential for fog which may become locally dense is expected each night this week.
