.Short term (rest of today - Tuesday)
high pressure building to our northwest will continue to advect
cooler air into our region. A dry and warm stable layer atop a
cool moist post-frontal airmass has helped to create a persistent
stratocumulus cloud deck. This will lift and dissipate some
over land during the afternoon, but the tug-of-war between
daytime heating and CAA will dampen this dissipation effect.

While it will be a chilly night, temperatures will remain above
freezing as mid-upper 30s are expected across the nature coast, low
to mid 40s across the i-4 corridor, and mid to upper 40s across
southwest fl. Light but noticeable winds will make it feel
approximately 5 degrees cooler in the morning hours.

Tomorrow, a secondary shortwave trough will dig down across the
southeast us and help to reinforce the cold air. It should be a
beautiful day but a sweater is definitely in store as temperatures
will not get out of the upper 50s to low 60s.

Mid long-term (Tuesday night - Monday)
Progressive pattern continues with upper trough quickly moving into
the atlantic to start the period then brief zonal flow through
midweek.

At the surface, high pressure centered over the area to keep temps
cold with light winds and radiational cooling Tue night Wed morning
for patchy frost over the nature coast with lower to mid 30 degree
temps. Elsewhere low temps should range from the upper 30s to lower
40s. High pressure then moves into the atlantic later Wednesday and
Thursday with E then SE winds for a moderating trend. By Thursday
enough moisture in place to introduce slight chance showers with
near normal temps.

Next southern jet stream storm system to move through the region
Friday but there are some subtle model differences in timing,
location and strength of features. The southern storm system to
impact the local area with showers and some thunderstorms ahead of
and along the front mainly Friday. Upper low to lift out of the deep
south over the weekend with drier wnw flow overhead Sun mon. Another
high pressure area builds into the region for cooler and drier
pleasant weekend weather conditions.

Aviation
18z TAF cycle. Widespread stratus deck will continue to
produce prevailing MVFR CIGS for all terminals. These
restricted ceilings should begin to improve this evening,
although some low stratocu will still remain. Gusty
northwest winds will begin to subside after sunset andVFR
is expected tomorrow.

Marine
Winds and seas will remain elevated today with headlines in place as
high pressure builds in across the central gulf states, creating
persistent northwest winds. The high slides east on
Wednesday Thursday and will veer winds offshore. Our next frontal
system approaches the area by Friday.

Fire weather
No concerns are expected over the next several days as rh, winds,
and recent rainfall will preclude extreme fire weather behavior.

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.
