AVIATION [Through 12Z Thursday] VFR conditions. WNW winds < 10 kts will veer NNE through the day and into tonight. May have some gusts by late morning near 15-20 kts due to elevated boundary layer winds near 25 kts, but gusts will decrease into the afternoon high pressure builds in from the west. High cirrus increase from the west late today, with some stratocumulus nearing SGJ Thu morning.

PREV DISCUSSION [233 AM EST] NEAR TERM [Through Tonight] Gorgeous weather day as high pressure dominates the region.

Continued dry, a bit warmer, and weaker winds as surface high pressure over the central Gulf Coast states shifts northward toward the Carolinas through tonight while an upper level ridge over the central CONUS shifts eastward. Mostly sunny skies will prevail today with increasing cirrus from the west into the evening. Light NNW winds < 10 mph will transition to NNE into the afternoon as the surface ridge builds to the north. Winds veer more ENE along the coast tonight with a few low level stratocumulus approaching the St. Johns and Flagler county coast after midnight.

Temperatures will moderate today as ridging builds in from the west. Highs will warm into the mid upper 60s across most zones to near 70 across our southern FL zones from GNV to OCF. Tonight, dry air will remain in place inland with a cool NNE drainage flow focusing the lowest mins in the 40s across inland SE GA and the Suwannee River Valley while NNE onshore flow increases moisture and raises lows into the low 50s along the NE FL Atlantic coast.

SHORT TERM [Thursday Through Friday Night] Surface ridge will shift eastward to the east coast on Thursday.

This will produce east to northeast winds across our area with the dry pattern continuing. Winds will veer to the southwest for Friday ahead of the next cold front. Temperatures will be near average on Thursday and then above average on Friday with highs reaching the mid upper 70s.

LONG TERM [Saturday Through Tuesday] Warm and mostly dry conditions for Saturday as cold front moves east into SW Ga by early evening. The front will move across the area Saturday night bringing a good chance of showers to the area.

The front will push SE of the area early Sunday morning with showers ending and decreasing cloudiness. Cooler and drier conditions behind the front will lower temperatures back to near average levels for Sunday and Monday. Temperatures will start to rebound on Tuesday as a return flow commences.

MARINE High pressure over the central Gulf Coast will build north toward the Carolinas through tonight. WNW winds over the waters this morning will veer more ENE into the afternoon with winds 10-15 kts and seas of 4-6 ft within the outer FL waters where the SCA was cancelled and replaced with Small Craft Exercise Caution. The high will settle south and build offshore of the southeast Atlantic coast Thursday and Friday. A cold front will track south across the local waters late Saturday with increasing SW Sat rising to SCEC and SCA conditions likely Sat night. High pressure will build east across the the Gulf of Mexico Sunday.

Rip Currents: Moderate risk today due to lingering easterly swells of 2 ft and periods of 13-14 seconds. Moderate risk expected Thu.

HYDROLOGY Tidal departures continued to dampen with most gauges along the NE FL coast and within the St. Johns basin reaching +1-1.5 ft MHHW around high tide. Scaled back the Coastal Flood (CF) products as water levels continue to gradually subside today. Cancelled the CF Statement for Camden & Nassau counties were high tides will peak below Action Stage. Replaced the CF Advisory with a CF Statement for Duval, St. Johns and Clay counties were tides will peak between Action and Minor flood stage. Continued the Coastal Flood Advisory for minor tidal flooding for Putnam and Flagler counties.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
