Near term [through today]
Similar to yesterday with a stout low-level inversion in place and
ample moisture just below within a continued, cool northwest surface
flow. With a bit more subsidence in place further removed from the
frontal passage on Sunday, it will be a dry day. High temperatures
were fairly close to guidance, with continued cold air advection
(nearing 0 c at 850 hpa), ranging from the upper 40s to lower 50s,
around 15 degrees below normal. It will feel several degrees cooler
with northwest winds 5-10 mph, and with the lack of sunshine, a day
to dress warm!

Short term [tonight through Wednesday]
A shortwave and its associated surface reflection will move through
the region overnight. In addition to the continued moist low-levels,
an axis of mid-level moisture and added lift with modest streamwise
vorticity moves through the region. Some brief, cold rain showers
are likely north of i-10, with sprinkles possible elsewhere. Low
temperatures in the low to mid-30s.

A dry stretch of weather is expected Tuesday through Wednesday as
high pressure moves from the lower mississippi valley to a position
near the southeast atlantic coast on Wednesday. It will remain cool
with temperatures several degrees below seasonal norms, yet slowly
moderating during this period. Tuesday night will be the coldest
with high pressure directly overhead. Expect lows in the upper 20s
to lower 30s, expect near 40 along the gulf coast. As the mid-level
ridge axis moves east of the area on Wednesday, time-sections show
an increase in mid to high level cloudiness. But again, it will
remain dry.

Long term [Wednesday night through Monday]
The main feature during this period will be another storm system
with the potential for addt'l heavy rainfall and thunderstorms.

Northern stream and southern stream energy are expected to phase
over the southern plains, leading to a mid-level low that closes
off and traverses the southeast us. The ECMWF continues to be the
deeper, slower solution, while the GFS is more progressive. The
500 hpa GEFS ensemble mean and spread conveys this uncertainty
well with considerable spread amongst the members. Like recent
systems, there will likely be ample moisture and robust dynamics,
so the potential for heavy rainfall and thunderstorms are the
primary concerns.

Aviation
[through 06z Tuesday]
MVFR due to low ceilings will prevail at all TAF sites through the
forecast period. Temporary ifr is possible in lower ceilings at aby,
dhn, and vld early this morning. Northwest winds around 10 kt across
the terminals.

Marine
Advisory conditions early this morning will give way to cautionary
conditions today. Cautionary or low-end advisory conditions are
again possible tonight and Tuesday. More tranquil boating weather is
expected later Tuesday through Wednesday night, before deteriorating
thereafter with cautionary or advisory conditions returning. There
is also the potential for a brief period of gales with another
strong cold frontal passage Friday into Saturday.

Fire weather
Hazardous fire weather conditions are not expected over the next
days. Low dispersions are not expected today, but are possible on
Tuesday.

Hydrology
Little rainfall is expected through Wednesday night and this will
allow the area to dry out some and most area rivers to become steady
or begin to slowly fall. The next rainmaker moves in for Thursday.

The withlacoochee, ochlockonee, apalachicola, chipola, and aucilla,
and are all in flood and either hold steady over the next few days
or begin a slow fall. The choctawhatchee and suwanee are expected
to enter flood over the next few days.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
