area forecast discussion

1013 am edt Thu aug 17 2017

Near term [through today]
With west-northwesterly flow prevailing across our area today,
highest chances of showers and thunderstorms should once again be
confined to our northern fl locations with the sea breeze pinned
near the coast. Adjusted pops accordingly, showing 40-60% across
northern fl and generally 20-30% across most of SE alabama and sw
georgia. Highs will range from the lower-mid 90s inland, and upper
80s along the coast. High humidity combined with this heat will
result in maximum heat index values reaching the mid-100s across
much of our area; be sure to limit physical exertion outdoors this
afternoon and early evening.

Prev discussion [1012 am edt]
Short term [tonight through Saturday]
Upper ridge centered across the northern gulf will slide westward
in response to a shortwave trough moving across the eastern third
of the us and an inverted mid upper trough moves westward into the
eastern gulf by late Saturday. A weak front, supported by the
shortwave trough, will move into the southeast and stall across
the area Saturday. Focus for showers and storms will be the
typical seabreeze each day and the front. The inverted trough will
also add some mid level support for shower storm development
Saturday. Some mid level dry air noted in area forecast soundings
may help to drive strong winds in heavier storms each afternoon
but are not expecting widespread severe weather. Temperatures
will remain in the lower 90s for highs and mid 70s for lows. Heat
indices will be in the low 100s each afternoon.

Long term [Saturday night through Thursday]
The aforementioned front hangs around the area through Sunday
night then lifts northward Monday as western atlantic high
pressure builds over the southeast us. Chances for showers and
storms each day will remain around typical summer norms and will
be driven by the seabreeze. Temperatures will remain seasonal with
highs in the lower 90s and lows in the middle 70s.

Aviation [through 12z Friday]
Vfr conditions with light winds through the period. Scattered to
isolated afternoon thunderstorms with brief periods of MVFR
conditions will be possible at tlh, vld, and aby.

Marine
Light winds and low seas will continue through the
weekend. Expect showers and storms in the overnight and early
morning hours each day.

Fire weather
Red flag conditions are not expected for the next several days.

Hydrology
Showers and storms are expected each day. Although minor flooding
could occur in urban and poor drainage areas, widespread flooding
is not expected.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
