Synopsis..Strong high pressure will remain in place over the western atlantic and florida through the end of the week with southeast winds in the 10 to 15 knot range along with warm and dry conditions continuing over the gulf waters through the period. The upper level high will weaken and shift west-southwest into the gulf during the upcoming weekend with the attendant surface high sinking south to lie across the north-central waters. This will allow for lighter winds with an onshore sea breeze component developing along the coast each afternoon. Wind and seas should remain below 15 knots and 5 feet with no headlines anticipated.

228 pm est Wed feb 21 2018

Above normal temperatures through the upcoming weekend...

Short term (tonight - Friday)
tonight... Strong mid level ridge will remain off the
southeast atlantic coast tonight with low level east
southeast flow around the low level atlantic ridge. A dry
airmass will continue across west central florida with warm
overnight low temperatures mainly in the 60s. Some patchy
fog may develop late tonight across the nature coast.

Thursday-Friday... The mid level ridge off the southeast
atlantic coast will retrograde toward central florida by
Friday afternoon. Subsidence from the ridge will keep mainly
dry and warm conditions continuing through late week. The
latest GFS model runs indicates some low shower perhaps by
Friday but with the strength of the overhead ridge will
leave rain chances just below mentionable range and lean
toward the drier NAM guidance for now. Highs will average
in the lower to mid 80s coastal areas and mid to upper 80s
across the interior. Lows will be in the 60s.

Mid term long term (Saturday - Wednesday)
the mid level ridge near the area Saturday will slip south
and elongate across south fl over the weekend and into early
next week. High pressure well east of the state will also
slip south and allow low level flow to veer to the southeast
satuday and southerly on Sunday. This will allow low level
moisture to gradually increase with some low diurnal shower
chances each afternoon through the weekend. Low level flow
will veer to the southwest Monday ahead of an approaching
frontal boundary into early Tuesday which will then lift
back north into mid week. This will should bring more
cloudiness and a chance of showers to the area for mid week.

Well above normal temps will continue over the weekend into
Monday and then temps will be slighly lower but still above
normal as the frontal boundary approaches the area into
Tuesday.

Aviation
Scattered to brokenVFR cumulus will diminish shortly after
sunset with mostly clear skies for the overnight. Some MVFR
fog may develop late tonight at klal and ft myers area
terminals.

Marine
High pressure across the atlantic will keep low level east
to southeast flow to 10-15 knots at times across the waters
into Friday. Winds will veer to the southeast Saturday and
southerly Sunday with winds becoming onshore near the coast
by late afternoon each day over the weekend. Mainly dry
weather will continue into the weekend with highest seas to
around 3 ft remaining offshore with good boating conditions
near shore. Winds will veer to the south-southwest Monday
ahead of the next front which is forecast to move through
the waters Monday night.

Fire weather
Adequate low level moisture will keep humidity values above
critical levels through the end of the week with no red
flag conditions expected. Breezy southeast transport winds
will result in elevated dispersion indices Thursday. Some
patchy fog will be possible during the late night and early
morning hours the next few days, with the best chances
across the fog prone locations of the nature coast.

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.
