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...
(18Z TAFS)
Issued at 1201 PM EDT Sat Jun 1 2024

Not much changes ongoing with the current TAF suite as VFR conds
will continue through the period as airmass still too dry to
support any convection near the TAF sites and just expect a mix of
FEW-SCT diurnal Cu field this afternoon around 4000-5000 ft with
SCT-BKN high clouds aloft at 15-25Kft. East-Southeast winds this
afternoon at 10-13 knots with gusts of 15-20 knots at times that
will fade to light SE-S south winds after sunset this evening.
Airmass still too dry to support any late night fog and any low
rainfall chances will likely not occur until after 18Z on Sunday
at any of the local NE FL/SE GA TAF sites.

&&

.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.
