area forecast discussion
national weather service jacksonville fl
409 am edt Wed aug 23 2017

Near term (today and tonight)...

surface high pressure will continue weakening this morning. Fog has
been a little slow to start this morning as we have some lingering
higher clouds, but at least some patchy fog can be expected around
sunrise across portions of florida. We'll likely see an increase in
convective coverage as a whole this afternoon as heights fall with
the weakening of the upper level ridge. There may be a drier area
in the middle of north florida as the trough south of us brings
activity northward and the upper level trough deepens southward
across southeast georgia. With the falling heights bringing
slightly cooler 500mb temperatures (-6 to -7c), a few stronger
storms are possible. Steering flow will be weak and generally
westerly and as has been the case, heavy rainfall and frequent
lightning strikes will be the main hazards. A cold front will move
through central georgia by late tonight. This trend for a stormier
pattern will continue in the coming days.

Short term (Thursday-Friday night)
Deep tropical moisture returns to the area as a tail end of a
mid upper trough and associated back door front approaches the
region. The front moves through the region Friday and stalls south
of the area (cntl fl) Friday night as high pressure builds well
north of the area. Light steering winds with added low level lift
and convergence will lead to scattered mainly diurnal storms driven
by the front as well as seabreezes and outflows. Localized flooding
is possible given the light winds and high pw (2+ inches). Afternoon
temps in the lower mid 90s on Thursday combined with the humidity
will produce heat indices from around 102 to 106 degrees across
inland areas while coastal areas will reach around 90 degrees with
heat indices of around 100 to 102 degrees. Slightly cooler temps
Friday due to more cloud cover with coastal areas remaining in the
mid to upper 80s due to a surge of northeast winds.

Long term (Saturday-Tuesday)
The remainder of the forecast is rather uncertain pending on the
evolution of the broad trough of low pressure across the bahamas and
south fl. Fairly good agreement with the GFS and ECMWF on some type
of low forming off the east central coast on Saturday and then
eventually getting pulled to the northeast from the southern
extension of the mid upper trough. The tropical weather outlook
indicates a low chance of the trough becoming tropical or sub-
tropical over the weekend and next week as the system is moving
offshore which leads to further uncertainty. There is continued high
confidence in more abundant clouds and cooler MAX temps mainly in
the rainfall forecast also still uncertain but have highest amounts
near the coast and lowest across inland southeast ga. Have followed
wpc QPF which has most of the heavier rain offshore but is subject
to change. Whatever does develop and eventually moves northeast... A
surface wedge setting up from new england into the deep south will
keep a moist northeast flow across the area into the early part of
next week and have continued with scattered pops with slightly below
normal MAX temps.

Aviation
Vfr conditions will give way to MVFR ifr fog and patchy ceilings
later this morning. Bases will rise to the low endVFR range (030-
050 feet) after 13-14z. Winds will be mostly westerly except right
along the coast as the seabreeze moves inland and shifts winds
southeasterly at 8-10 knots. Scattered thunderstorms will develop
this afternoon.

Marine
High pressure centered off the southeast u.S. Coast will move slowly
eastward during the next few days. A weak low pressure trough will
remain situated near south florida through Friday. Winds are
starting to become southwesterly over the coastal waters, however
the atlantic sea breeze will develop on this afternoon and on
Thursday near the coast, with onshore winds expected to remain below
caution levels each afternoon. A long period east southeasterly
swell is keeping combined seas elevated in the 3 to 5 foot range
offshore, and will only gradually fade on later tonight. A cold
front will approach the southeast georgia waters from the north by
late Thursday, and this front will slowly move southward into the
northeast florida waters on Friday. Low pressure is forecast to
develop off the east central florida coast by Friday night and will
move slowly northeastward this weekend. Onshore winds will
strengthen over the weekend, with small craft advisory conditions
possible by Sunday.

Rip currents: a persistent and long period east southeasterly ocean
swell will keep a moderate risk of rip currents in place at area
beaches through Wednesday.
