Near term [through tonight]
18 utc satellite imagery and surface data show northwesterly flow
in place across the forecast area this afternoon. Cumulus field
has been slow to develop with some drier air present aloft.

However, model guidance suggests that this will gradually be
overcome late this afternoon as convergence increases with the sea
breeze front along the franklin county coast. Multiple hrrrs and
the local 12z WRF show storm development initiating after 19z
today in the florida panhandle and spreading into the western
florida big bend just prior to sunset. As a result will show 40-50
percent pops in this area through the remainder of the afternoon.

Thereafter, convection should diminish rapidly after sunset.

Overnight, expect another round of offshore storms to develop
after 08z and remain over the coastal waters at sunrise. Lows
should be in the mid 70s.

Short term [Saturday through Sunday night]
Overall, the area will be in a mid upper col region with very weak
deep layer flow over the next few days. At lower levels, general
northwesterly flow is on tap, with a relatively dry airmass in
place (especially on Saturday). Northwest flow is generally dry
for the northwestern half of the area, so will have low pop for
that region. Best rain chances will be south of i-10 and over the
eastern big bend. Very warm conditions will continue with highs in
the mid 90s on Saturday.

By Sunday, the low-level flow will shift around to the east, with
some moistening of the deep layer. Therefore, may see a bit more
coverage of afternoon showers and storms.

Long term [Monday through Friday]
A weak tropical wave is forecast to move across the region on
Monday, which will increase cloud cover and rain chances (which
could dampen eclipse viewing). Through the remainder of the week,
typical summertime conditions will persist with scattered
afternoon and evening thunderstorms each day.

Aviation [through 18z Saturday]
Sct tsra are expected to develop this afternoon across the florida
panhandle, most likely impacting ecp prior to 20z and potentially
reaching as far east at tlh before 23z. With greater likelihood at
ecp included a tempo for ifr conditions there. Further inland, do
not anticipate tsra development at aby dhn vld. After sunset, tsra
should end withVFR conditions prevailing through the remainder of
the period, except at vld where a brief MVFR vsby is possible prior
to sunrise.

Marine
Outside of scattered showers and thunderstorms, winds and seas
will remain rather low through the forecast period.

Fire weather
Red flag conditions are not expected over the next week.

Hydrology
Area rivers are below "action stage" and will remain so through
this weekend. Organized heavy rain is unlikely.

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.
