Short term (rest of today-Monday)
An upper low near the south-central mississippi valley this
afternoon tracks southeast to the ga/sc border. A short
wave trough over southern fl lifts northeastward and is
absorbed into troughing from the upper low. At the surface a
low in northern ga trails a cold front south across the fl
panhandle then southwestward over the gulf of mexico. The
surface low move to the carolina coastal waters by late mon
afternoon with the front sweeping into the east gulf tonight
then across the state mon. In response to the front and the
upper level short wave trough... A surface trough over the
straits from western cuba to the northern bahamas lifts
northeast and merges in the carolina surface low.

The deepest moisture... Model pwat values at 2 inches or more...

which resulted in some record rainfall in the south has shifted
away. However enough residual moisture... Pwat in the 1.5 to 2 inch
range... And instability remain which along with sea breeze
convergence and limited day time heating to support a chance of
showers and a slight chance of thunderstorms through the rest of the
afternoon. There should be a break in rainfall from late afternoon
or early evening through the later night hours. But expect some
cloudiness along with patchy late night fog... Especially in areas
that received rain. Slightly deeper moisture returns with the front
but limited with pwat in the 1 to 1.5 inch range... Enough for
scattered showers or a few thunderstorms. The front and associated
weather begin to impact... The nature coast in the pre-dawn
hours... The tampa bay area around sunrise... Southwest florida around
mid-afternoon... Then exits by late afternoon. Winds will pick
noticeable with the front but will mainly be of concern for
aviation/marine interests.

Mid term/long term (Monday night-Sunday)
Monday night into Wednesday the mid/upper level shortwave trough
will continue to move up along the eastern seaboard away from the
region followed by ridging gradually build over florida as a
deepening trough sets up over the western half of the CONUS late in
the week through the weekend. At the surface weak high pressure will
be over the area for Monday night through Thursday, then late in the
week into the weekend a stronger high pressure will build in from
well out in the atlantic ocean. For Monday night into Tuesday night
a low level west to northwest flow will be in place bringing some
cooler and drier air into the region under fair skies. During
Wednesday and Thursday the flow will shift to south to southwest
with limited moisture continuing across the region so expecting
mostly clear to partly cloudy skies with rain chances less than 10
percent. For Friday through Sunday the low level flow will shift to
southeasterly with moisture gradually increasing leading to some
additional clouds. There will be a slim chance, less than 20 percent,
for a light shower/sprinkle Friday, then over the weekend some more
moisture could move into the region leading to a few showers, but
will keep rain chances at around 20 percent at this time as moisture
does not look that deep. Temperatures will be close to normal for
Monday night and Tuesday then as the ridging builds aloft we'll see
a gradually warm up a couple of degrees each day reaching the mid
80s coast to the lower 90s inland for Friday through Sunday.

23/18z-24/18z. Bkn mid deck spreads north this afternoon as all
terminals swing to westerly winds. Isold tsra expected around 20z-
24z. GenerallyVFR over night with sct-bkn clouds... Possible MVFR
cigs tpa and pie... And lal and pgd could see some limited late night
br. Front arrives at the northern terminals around sunrise with
vcsh... Aft 18z at southern terminals. Westerly winds begin to pick
up toward the end of the period.

A trough of low pressure moves beyond the waters tonight as a cold
front slides into the east gulf... Then across the state mon. High
pressure builds back in Tue and continues for most of the week...

with an axis meandering around central/north fl.

The main concerns may be a few thunderstorms this afternoon but
expect these to mainly be onshore. The front tonight-mon will come
through with showers although can not rule out a thunderstorm or
two. Winds increase in the wake of the front... Up into the exercise
caution range Mon afternoon-night.

Fire weather
Recent heavy rainfall... Especially in the south... Along with more
limited rain as a cold front moves through late tonight and during
mon will provide enough moisture to preclude any low rh concerns 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. 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 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.
