305 pm edt Thu jul 18 2019

Scattered thunderstorms remain in the forecast through the end
of the week...

Near term Rest of today and tonight...

upper level cirrostratus stretched across the area late this morning
and early afternoon has resulted in some differential heating
from north to south. As a result, the convective initiation is
rather disorganized with thunderstorms initiating off the east
coast sea-breeze in flagler county and the gulf coast sea-
breeze outflow boundary forcing a few storms along the suwannee
river. Further north into SE georgia, storms have generally formed
along and north of us-84 where an instability axis exists. A
ridge axis stretched from e-w along the fl ga border suggest
storms across SE georgia will slowly move SE and storms across ne
florida will slowly move westward. Storms over NE florida will
slowly work toward inland area with perhaps colliding boundaries
over the central parts of the the peninsula late this afternoon
and early evening. Across SE georgia, activity moves toward the
coast with storms merging with the inland moving sea-breeze near
the i-95 corridor. With the upper level clouds, coverage will be
more limited today. As storms weaken this evening, remnant showers
will remain where late afternoon storms develop and dissipate.

For the overnight, expecting partly cloudy and dry conditions with
temperatures dropping into the low to mid 70s.

Short term Friday through the weekend...

tropical moisture continues to persist over the region for Friday as
another round of scattered to widespread showers and
thunderstorms is expected. Remnant vorticity centered over georgia
will help aid the development in these areas producing widespread
coverage with NE florida primarily seeing scattered sea-breeze
initiation during the early afternoon. The lobe of vorticity moves
west of the area, along with the deep tropical moisture, into the
weekend, with typically scattered sea-breeze driven convection
expected. Temperatures will be a few degrees above normal this
weekend with low to mid 90s forecast.

Long term Monday through Thursday...

zonal upper air pattern begins to amplify early next week as a trough
descends into the midwest. The trough approaches the southeast on
Tuesday before stalling over the local area for the remainder of
the week. With a tropical airmass parked over the region, the
expectation will be for above average precipitation and near
normal high temperatures (low 90s area wide). With southwest
surface flow, night-time lows will be above average. Depending on
how far south the trough pushes, any vorticity generation in the
ne gulf will help to enhanced rainfall across the area as these
features moves northeast along the front.

Aviation
Some high-level cirrus has delayed heating a bit and timing of
storms more into the 19-21z for the coastal TAF sites of crg sgj
and 20-23z for jax vqq gnv ssi. Have continued tempo groups for
potential wind gusts to 25 knots and possible ifr vsbys and MVFR
cigs at times in thunderstorm activity. Still expect conds to
improve in the 00-02z time frame withVFR conds and just some
debris high clouds during the overnight hours. Any chances for low
clouds patchy fog too low to include for vqq gnv at this time.

Marine
Broad area of high pressure will persist over area waters through
the rest of the week and into the weekend keeping wind weak and
seas low. A trough of low pressure moves into the southeast
during the middle part of next week with increasing chances for
showers and thunderstorms.

Rip currents: low risk of rip currents.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
