Aviation [through 12z Tuesday]
Vfr today and tonight with light southeast winds. Isolated tsra
will develop this afternoon but probability to impact any TAF site
is low. Overnight, patchy fog is possible at TAF sites with the
exception of ecp. Flt conds will fail to ifr MVFR beginning around
09z.

Prev discussion [427 am edt]
Near term [through today]
Deep layer ridging will remain in place over the florida peninsula
today, with south-southeasterly flow at the lower levels and
west-southwesterly flow at the mid and upper levels. A cold front
stretches from the great lakes southwestward into the lower ms
valley and into southeast tx. Ahead of this front, scattered
showers and isolated thunderstorms may develop across the area in
the late morning- early afternoon, with the highest chances in
southeast al and the fl panhandle. Highs today will be in the
upper 80s to low 90s the eastern big bend with heat indices
ranging from low 90s in southeast al and southwest ga to the upper
90s along the north fl coastline.

Short term [tonight through Wednesday]
The weak cold front will move into the forecast area Tuesday
night through Wednesday morning before stalling over the area
Wednesday. Pwats will rise to 1.5-2" across the area, but forcing
and instability will remain weak, so pops will stay in the 20-30%
range with this system. Rainfall accumulations will be
correspondingly low, remaining below an inch. Morning lows will be
in the upper 60s to low 70s both Tuesday and Wednesday morning.

Afternoon highs will be in the upper 80s to low 90s on Tuesday,
but will be cooler (low 80s) on Wednesday in southeast al where
the front will have passed earlier in the morning.

Long term [Wednesday night through Monday]
The cold front will stall across our coastal waters Wednesday
night, then push back northward on Friday. Temperatures will peak
in the upper 70s to low 80s for most of the week, with lows mostly
in the 60s. Pops will remain low through Friday night, then
increase to 30-50% ahead of the next front. This second, stronger
cold front will push into the area Saturday. Behind this second
front, lows may dip into the mid 50s in parts of southeast al,
low-mid 60s elsewhere with highs in the upper 60s to mid 70s.

Marine
High pressure will move off the eastern seaboard today as a weak
cold front approaches the area. The front will move into our

before lifting northward again Friday. A few rounds of cautionary
winds are expected with this approaching frontal system- first
Wednesday night and then again on Thursday night.

Fire weather

winds and dispersions will stay on the lower end, even during
daytime hours. Otherwise, no hazardous fire weather conditions
are forecast.

return to moderate flood tonight. With no significant rainfall in
the forecast, no additional flooding is expected for the next few
days.

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.
