Marine Weather and Tide Forecast for Neptune Beach, FL

NEAR TERM /THROUGH TONIGHT/
This afternoon...NE wind surge has pushed frontal boundary southward and currently remains stalled along a line from Ocala to Palm Coast.
Northeast winds have increased to 15-20G25mph along the Atlantic Coastal Counties and generally in the 10-15G20 mph range over inland areas. Low stratus has broken up in some areas, but abundant mid and high clouds remain and still only expect Max Temps around 60F across SE GA and in the 60s along the I-10 corridor, and some lower 70s still possible for Marion/Putnam/Flagler counties. A few light rain showers are possible through the early evening hours as the frontal boundary start to lift northward as a warm front, but overall measurable rainfall chances remain around 20 percent or less.

Tonight...Warm frontal boundary will slowly lift northward through the local area with cloudy skies continuing along with low stratus development. Still expect some low end rainfall chances as the warm front lifts northward, mainly along the Atlantic Coastal Counties and I-95 corridor but still only expect some light showers and/or sprinkles at the most with measurable rainfall chances still around 20 percent or less. As the warm front lifts northward the winds will weaken across NE FL, while a small pinched gradient will continue along the SE GA coastal counties with breezy NE winds at 15G25 mph through most of the night. South of the warm frontal boundary across NE FL, the influx of higher dewpoints and light south winds will aid in the development of sea fog along the NE FL coastal areas as well as locally dense fog over inland NE FL as well. Dense fog advisories may be required for portions of NE FL and for the nearshore NE FL Atlantic Coastal waters by the overnight hours. Mild overnight lows in the 50s across NE FL, with mid/upper 40s across SE GA.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/
A warm front lifts northward across the area Sunday morning as a cold front approaches from the northwest, shifting through the area on Sunday night to Monday morning. Southerly to southwesterly winds become established behind the warm front on Sunday allowing for warmer air to filter into the area leading to near record warm temperatures for locations across NE FL. Daytime highs are expected to reach into the upper 70s to mid 80s across NE FL, with the warmest temperatures across north central FL, while daytime highs in the mid 70s to lower 80s across SE GA. Showers begin to filter into SE GA during the late afternoon hours ahead of the approaching cold front. In addition to numerous to widespread during the overnight hours, isolated thunderstorms will also be possible as the front pushes across the area. With any storms that do develop, main hazards will damaging wind gusts and potentially a brief tornado along the far interior of SE GA.

The last of the remaining showers push offshore during the morning hours on Monday. Behind the cold front, breezy northwesterly winds will begin to bring much colder and drier air into the area. Cool daytime highs in the lower to upper 50s across inland SE GA and the Suwannee Valley Region in NE FL, while northeast and north central FL will be in the 60s, some locations may push into the lower 70s along Palm Coast. By the evening hours, sub-freezing temperatures make a return to the area as Lows plunge down into the 20s. The cooler temperatures and relatively windy conditions will bring wind chills down into the teens across SE GA and southwards towards portions of northeast, with north central FL and coastal locations having wind chills in the lower 20s, with a Cold Weather Advisory may be needed.

LONG TERM /TUESDAY THROUGH SATURDAY/
High pressure will park itself over the SE CONUS during much of the upcoming week. Colder and drier air over the area will bring a span of days in which daytime highs only reach into the upper 40s to mid 50s. In addition to the colder afternoons, we will also have a span of nights with overnight lows dipping to sub-freezing temperatures, with widespread inland freezes likely each night. The low temperatures in addition to winds each night may be enough to warrant a need for some Cold Weather Advisories, as wind chills dip to criteria levels.

Looking to next weekend, guidance continues to show a low pressure system developing across the Gulf and pushing across the FL peninsula. With the latest 12Z run, models suggest a mostly dry passing across our local area on Saturday. As always, we will keep an eye for better model consistency.

AVIATION /18Z SATURDAY THROUGH 18Z SUNDAY/
Low stratus has mostly broken apart early this afternoon with a mix of VFR conds and occasional MVFR CIGS at times in the gusty NE flow at the regional terminals. These conds will hold in place for a few hours before the NE winds weaken towards sunset with a return to IFR CIGS in the 00-03Z time frame, then as the warm front lifts north across the regional terminals, expect further reductions to LIFR conds at all TAF sites in the 03-06Z time range, with another night of high confidence in LIFR CIGS, but lower to moderate confidence in the VSBYS with best chances for LIFR VSBYS at GNV/SGJ and IFR VSBYS at CRG/JAX/VQQ and MVFR VSBYS at SSI during the overnight hours between 06Z-14Z. As the warm front lifts north of the regional terminals late in the 18Z TAF period, expect a return to IFR conds in the 14-16Z time frame and MVFR conds in the 16-18Z time frame as south winds start to slowly increase to 10-15 knots by the end of the TAF period.

MARINE

Surge of Northeast Winds and Small Craft Advisory conditions this afternoon and evening will slowly weaken as a warm front lifts northward through the local waters late tonight, then southerly flow increases on Sunday. Strong cold frontal passage Sunday Night with a few strong and gusty thunderstorms expected. Very cold Northwest flow and Small Craft Advisory conditions are expected on Monday, which will weaken slightly on Tuesday and Wednesday, before another strong Arctic cold front pushes through the local waters on Thursday with Small Craft Advisory conditions once again.

Rip Currents: High Risk of rip currents in the NE wind surge today as surf/breakers build into the 3-6 ft range. Have extended the High Risk of Rip currents through Sunday due to the lingering 3-6 ft surf even though the winds shift to the South, also the warmer air temps on Sunday at the NE FL/SE GA beaches may attract some folks to even venture into the water.

A few storms may be strong Sunday evening, especially across interior southeast Georgia and the Suwannee Valley.
