Aviation
[through 00z Thursday]
this evening CIGS are already ifr in most locations. Lifr CIGS can
be expected late tonight and in the early morning hours. Patchy fog
is likely. Rain will become more widespread late tonight. By late
morning to early afternoon rain will become steadier and heavier.

Ifr conditions will persist for most of tomorrow morning and
afternoon.

Prev discussion [254 pm est]
Near term [through tonight]
Cold front continues to press eastward across the forecast area this
afternoon, moving through tallahassee around 18z. Scattered showers
and thunderstorms ahead of the front will continue to move eastward
as well through the afternoon. Behind the front, there is a break in
the precip across the big bend and SW georgia, with additional
rainfall developing and moving inland into the florida panhandle and
se alabama. This area of precip will slide slowly east through the
afternoon, producing a widespread area of light rain. Overnight,
this area of rain will increase in coverage as isentropic lift
strengthens ahead of a deepening trough digging into texas. While
coverage should be widespread, the intensity is expected to be
limited, with only modest QPF amounts in the forecast. With this in
mind, will go ahead and cancel the flash flood watch.

Short term [Wednesday through Thursday night]
Upper low will start this period over the ARKLATEX and move
northeast towards the DELMARVA while slowly weakening over time.

Cold front will stall to our south while another area of low
pressure will develop in response to a shortwave trough moving
through the flow. This surface low will race northeast and drier
air will sweep in on the backside and dry the weather out from
west to east Wednesday night into Thursday with decreasing clouds
Thursday afternoon. Thursday night will be dry. Temperatures will
be at or below normal this period.

Long term [Friday through Tuesday]
Zonal flow sets up across the southeast CONUS this period with
surface high pressure dominating through Monday. A weak frontal
boundary does move into the southeast states but moisture is
lacking and just a mere increase in clouds is expected.

Temperatures will be below seasonal averages through the weekend
then around average early next week.

Marine
Winds will be moderate to strong over the next few days with
alternating advisory and caution conditions likely. Rain will
continue through Thursday then dry weather into the next weekend.

Fire weather
Aside from low dispersion indices, hazardous fire weather
conditions are not expected.

Hydrology
Periods of moderate to heavy rainfall will continue through
Wednesday night with dry conditions beginning Thursday. Generally
1-2 inches of rainfall is expected with isolated amounts up to 4
inches. The heaviest amounts will generally be across SE alabama
and southern georgia. Isolated flash flooding will continue to be
a concern. There are several river basins, especially across the
florida panhandle, that are in action stage with forecasts into
flood such as the chipola, shoal, and choctawhatchee near bruce.

These will need to be watched over the next 24 to 36 hours or so.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
