NEAR TERM /THROUGH TONIGHT/

- Extreme Wildfire Weather Conditions through this evening - Gusty coastal conditions: Rip Currents and hazardous rec boating

Extremely critical fire weather conditions are the primary weather concern through the rest of the afternoon and early evening as gusty northeasterly winds, frequently gusting between 25-30 mph, continue amid exceptionally dry conditions.

Considering the active and growing wildfires. The smoke generated, specifically from the Pineland Road fire in Clinch/Echols border in SE GA and the Crews Road Complex on the Putnam/Clay county border, will push thick smoke downwind (to the southwest) through the early evening hours, restricting visibility at times.

Outside of the red flag conditions, cooler temperatures in the dry post-frontal airmass have kept afternoon highs generally in the 70s despite full sun.

Tonight, winds will ease up as the pressure gradients are alleviated by high pressure builds from the spine of the Appalachians eastward to the Mid Atlantic coast. As winds settle, temperatures will become much cooler with inland temps falling to the mid/upper 40s while mid/upper 50s are forecasted for the immediate coastal areas.

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/

Main Highlights This Period:

- A Red Flag Warning is in place for portions of inland NE FL on Tuesday - Critically low minimum humidity values for inland locations into midweek

High pressure conditions will continue to dominate the weather pattern through Wednesday with fair weather, critically dry humidity values over inland areas, and diminishing winds as the center of high pressure rotation passes over the forecast area from out of the west. Diurnal sea breeze winds will bring in slightly less dry conditions for coastal counties. High temperatures through midweek will rise into the lower to mid 80s for inland areas and in the upper 70s for areas nearer to the coast. Overnight low temperatures will drop down into the lower to mid 50s over inland areas and in the upper 50s and lower 60s for areas near the shoreline.

LONG TERM /THURSDAY THROUGH SUNDAY/

Main Highlights This Period:

- Dry conditions persist through work week - Isolated T'storms possible Saturday and Sunday - Warming Trend this Period

Potential for showers and possible thunderstorms will increase over the weekend as high pressure moves off to the east and a slightly more moist flow moves across the region from out of the west raising relative humidity levels above critical levels by Saturday and Sunday. Temperatures will experience a heating trend through the end of the week and into the weekend, with above average max temps reaching into the lower 90s by Saturday.

AVIATION /18Z MONDAY THROUGH 18Z TUESDAY/

Gusty northeasterly winds continue with gusts up to 30 knots through around 21z, with gradual easing through sunset this evening. Otherwise, VFR conditions are expected throughout the period. Lofted smoke generated by existing or nearby wildfires may impact approaches for inland airfields. Northeasterly winds will develop through the morning hours Tuesday, turning easterly as the Atlantic sea breeze develops and quickly tracks inland during the early afternoon Tuesday.

MARINE

Gusty northeasterly winds across the waters, resulting in Small Craft Advisory conditions, will begin to ease tonight with seas gradually lowering thereafter. Easterly winds Tuesday into Wednesday will become southeasterly Thursday into Friday with southerly winds ahead of a cold front approaching and stalling near the local waters this weekend.

Rip Currents and Surf:

High risk of rip currents today with elevated onshore winds from the northeast and surf breakers up to 4-6 feet. A moderate to high risk is anticipated for Tuesday with easterly onshore flow.

FIRE WEATHER

Strong high pressure builds in from the northwest with breezy northeast winds near 15 mph gusting to 25 mph and critical MinRH values 15-20 percent will create dangerous wildfire conditions. A Red Flag Warning is in effect for all of inland Southeast GA in Northeast FL locations west of the St. Johns River. Additionally the breezy surface and transport winds will create high dispersions Today. Dry and breezy conditions will again be present across inland NE FL on Tuesday, with a Red Flag Warning set for inland NE FL on Tuesday. A Fire Weather Warning has been set on Tuesday for portions of inland NE FL.

The high pressure over the area Tuesday and Wednesday will gradually move east of the area Thursday into Friday. This will lead to the breezy east to northeast winds to diminish on Wednesday with daily Atlantic seabreeze moving well inland into Friday. Dry conditions will persist and critical MinRH values over inland Southeast GA and portions of northeast FL each day this week. Areas to widespread high daytime dispersions are expected daily into at least Thursday due to high mixing heights and moderate transport wind speeds.

FOG POTENTIAL AND OTHER REMARKS: There will be potential for Localized "superfog" near the vicinity of any smoke from ongoing wildfires
