Hoboken, GA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis.. A surface trough across the area will weaken through the weekend. Breezy southwest winds will decrease some tomorrow as flow remains offshore. A cold front will then approach the georgia waters from the north on Tuesday. It is expected to stall near the florida border towards midweek, bringing back onshore flow for the remainder of the week.

area forecast discussion
national weather service jacksonville fl
410 pm edt Sat jun 23 2018

Hot today but even hotter tomorrow with dangerous heat index
values expected inland...

Discussion
Very dry and subsident air mass remains across the area. A few
storms over north central florida were able to develop as the gulf
seabreeze moved inland in predominant westerly flow. Further to
our north, strong thunderstorms have developed along a shortwave
trough. This activity could clip our far northern counties across
southeast georgia, but with the dry airmass in place it would be
difficult for storms to hold together. Nevertheless, some
southward moving outflow boundaries could spark some isolated
convection over coastal southeast georgia later this afternoon and
evening. Overnight thunderstorm activity should wane with diurnal
heating, but with plenty of CAPE and outflow boundaries a few
showers or thunderstorms are possible.

Hot temperatures will likely be the main feature tomorrow as the
upper level ridge amplifies. Heat index values will still be in
the low 100s at the coast despite the development of the atlantic
seabreeze. Inland, heat index values will soar to around 110, and
possible near excessive heat advisory criteria of 113. For now
have opted for just an advisory, and if any isolated convection
can develop tomorrow it may lower the readings across north
central florida. Models seem unimpressed with convection for the
most part tomorrow though, owing to the strong subsidence in
place. Pwats should be on the rise though as mid and upper level
flow shifts to become more easterly from the dry northwest flow of
today. On Monday, heat index values will again be near or well
into advisory criteria for most of the area. The upper level ridge
will start breaking down some though, and as heights fall the
possibility for diurnal convection along the seabreezes may help
keep those index values in check. 500mb temperatures remain around
-8, so while a few storms could become somewhat strong heavy
rainfall may be the higher concern as pwats approach 2 inches.

500mb temperatures will continue to decrease despite very weak
upper level ridging remaining in place across much of the
southeast through the week. A very weak shortwave trough and
surface trough will drop southward on Tuesday and Wednesday, and
should act to enhance coverage of diurnal thunderstorms. With weak
surface and steering flow, seabreeze convection and mergers will
be common each afternoon through the end of the week.

Aviation
Vfr conditions will continue for the rest of today, tonight, and
into tomorrow. Winds will be predominantly out of the west today
with strong winds and wind gusts of approximately 20 knots which
will slow later in the afternoon and become light and variable
overnight. Conditions tomorrow morning will beVFR overall, with
the possibility of some lower cloud decks in the morning.

Marine
General offshore flow at 10-15 knots with seas 2-4 ft will
continue through the weekend. A weakening frontal boundary drifts
south into the waters Tuesday with lighter and more variable flow
with local sea breezes.

Rip currents: low risk
