Marine Weather and Tide Forecast for Nicholls, GA

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
High pressure will build to the northwest through Tonight with clear skies. Another unseasonably cold night is forecast, with a widespread inland freeze with frost expected. The flow will largely be parallel to the NE FL coast overnight, helping keep coastal NE FL communities above freezing.

With winds stirring through the night, wind chills will fall into the 25 to 30 degree range inland. A few spots may reach the 25 degree wind chill criteria in NE FL, but not enough coverage expected to warrant a cold weather advisory at this time.

SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/
After a chilly start again from Tuesday morning, temperatures will rebound back into the 50s and 60s Tuesday afternoon under increasing high clouds as an upper disturbance develops over TX. Conditions ill remain dry as the high pressure over the southeast states moves off to the east and northeast, leaving sfc ridge back over the Carolinas to northern parts of GA. Weak coastal trough may form offshore by late Tuesday night. Not as cold Tuesday night/Wed morning under considerable high clouds, but expect still a freeze over parts of inland southeast GA into parts of far northeast FL, but otherwise upper 30s to lower 40s elsewhere. Wednesday into Wednesday night, considerable mid-high clouds as the aforementioned mid/upper level disturbance moves into the northwest and central Gulf by the end of Wed night. While conditions still look too dry with generally insufficient low level moisture, we'll have POPs to about 10 percent for now by Wednesday night as there may be some sprinkles & virga around the forecast area. Highs Wednesday rise to the 60s to around 70, and lows Wednesday night moderate to the 40s and lower 50s under still weak high pressure ridging over the local area.

LONG TERM /THURSDAY THROUGH MONDAY/
A low chance for showers on Thursday to Thursday night as the upper level disturbance passes over the forecast area. Considerable cloudiness starts the day, but drier air will eventually filter in by Thursday night with some clearing anticipated. A weak, shallow cool front moves through late Friday into Friday night with very low rain chances expected, and the front may slow its southward movement as a frontal wave moves through over the weekend. There are better chances for showers Saturday through Sunday, especially north half of area, as strong forcing develops aloft and another front reinforces the cool air over the region by Sunday. Temperatures will trend to be near and above the seasonal average through the end of the week and Saturday, but colder on Sunday to near or below normal.

AVIATION /00Z TUESDAY THROUGH 00Z WEDNESDAY/
VFR conditions to persist through the 00Z TAF period. Light Northwest winds tonight will increase to 10-12G15-18 knots by 15Z and continuing through the Tuesday afternoon hours.
