New UPDATE

UPDATE
Issued at 918 PM EDT Sat Jun 1 2024

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

Forecast is looking good this evening with only some mention of light showers skirting onshore the SE GA coast over the next couple of hours before fizzling with inland extent.

Near seasonal overnight lows expected with mid 60s to near 70 degrees away from the coast and low 70s along the coast under occasionnal mid and high level clouds. Incerasing moisture Sunday will support isolated to widely scattered showers and T'storms initiating along the merging seabreezes west of highway 301 while weak shortwave energy passing aloft. Partly to mostly cloudy skies will keep highs near normal in the southeasterly flow up to near 90 degrees over north central FL and upper 80s north to the FL/GA state line and west of the St Johns river and low to mid 80s at the coast.

NEAR TERM
Issued at 130 PM EDT Sat Jun 1 2024

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

East to Southeast steering flow still on track to push Atlantic sea breeze well inland and still possible isolated showers and/or storms to develop as it reaches the Gulf Coast sea breeze or outflows from ongoing storm activity over SW GA. Not expecting much convection as abundant dry air mixing in with any activity will keep rainfall chances around 20% or so. The delayed start to any convection will allow for slight chance PoPs continue this evening into the overnight hours. Cloud cover will remain partly to mostly cloudy tonight as leftover convective debris clouds from convection west of the region will continue with lows in the 65-70 range inland and 70-75 along the Atlantic Coastal areas. The airmass will likely remain too dry and mixed through the overnight hours for any fog formation.

SHORT TERM
(Sunday through Monday night)
Issued at 130 PM EDT Sat Jun 1 2024

Moisture will begin returning to the region on Sunday, with PWATS generally rising above 1.5 inches area-wide. Both Sunday and Monday, scattered showers and embedded thunderstorms are expected, with the highest coverage of storms being in the afternoon as the east coast sea breeze moves inland. Diurnal instability and increased moisture will promote thunderstorms, however with weak mid-level lapse rates forecast, only isolated to widely scattered storm coverage is likely both days.

Highs Sunday will reach the mid 80s to lower 90s, with a slight warm up forecast for Monday. Mild low temperatures forecast, in the upper 60s to lower/mid 70s along the coast.

LONG TERM
(Tuesday through next Saturday)
Issued at 130 PM EDT Sat Jun 1 2024

Temperatures will remain hot this week as high pressure builds overhead, with a gradual slight increase in temps each day through Friday. By Thursday, with steering flow will shift southwesterly, so even the immediate east coast will see high temperatures in the lower 90s.

The general daily trend will be an afternoon/evening isolated to scattered thunderstorm risk as the sea breezes move inland and soaring temperatures create enough surface based instability.
Although far out in the forecast, it appears a front will approach from the northwest late this week, timing and impacts still have a decent level of uncertainty.

AVIATION
(00Z TAFS)
Issued at 755 PM EDT Sat Jun 1 2024

VFR conditions will continue overnight into Sunday as high pressure builds just east of the Outer Banks of North Carolina with light east to southeasterly winds 5-8 knots diminishing to variable around 3-5 knots towards 06Z. Dry airmass and presence of mid and high level clouds will limit any chance of significant fog through sunrise. Weak impulse aloft traveling in from the FL peninsula and the collision of the east coast seabreeze with Gulf seabreeze far inland near or just west of GNV after 19Z will create enough coverage of widely scattered showers and thunderstorms to warrant VCTS at GNV with some of this activity pressing towards the coast by late afternoon due to higher level westerly wind flow and have placed VCSH after 21Z for JAX, CRG, VQQ, SGJ, and SSI. Mid level clouds will persist and lower as moisture increases Sunday across the area. Winds will be predominatly southeasterly 6-8 knots inland with more easterly winds behind the Atlantic seabreeze 8-10 knots at duval county TAF sites and 10-12 knots at the coast where some higher gusts around 15-10 knots possible.

MARINE
Issued at 130 PM EDT Sat Jun 1 2024

High pressure will build off of the Carolinas this afternoon into Sunday with winds turning more southeasterly. The high will shift near Bermuda early next week with lighter southeasterly winds turning southerly midweek with isolated thunderstorms returning to the waters in the afternoon and early evening as a cold front approaches from the northwest on Friday with winds turning southwesterly.

Rip Currents: Moderate rip current risk on Sunday for NE FL and SE GA beaches as onshore winds begin to calm.

HYDROLOGY
Issued at 303 AM EDT Sat Jun 1 2024

Water levels continue to recede along lower portions of the Satilla River near the gauge at Atkinson, where water levels will fall below flood stage by this afternoon to evening. Water levels have already begun to recede along lower portions of the Santa Fe River near the gauge at Three Rivers Estates, but minor flooding will continue through most of the upcoming week due to backwater flooding effects from action level water levels along lower portions of the Suwannee River.
