238 pm est Thu feb 22 2018

Short term (tonight - Friday)
A highly amplified upper level pattern continues over the u.S.

Troughing dominates the western half of the country while strong
persistent ridging remains over the east coast. The upper high sits
off the carolina coast and ridges southwest over florida and into
the gulf of mexico. This pattern will hold strong through Friday and
into the weekend. On the surface, strong high pressure sitting over
bermuda ridges west over the southeast u.S. And northern florida.

This will keep a predominant easterly flow over the region, which
will prevent any strong push of the west coast sea breeze inland
today and on Friday. Any shower activity will be limited to
southwest florida on an east-southeast flow from southeast florida.

With no real change in the synoptic pattern, there will not be any
cool down through the period. Temperatures will remain well average
through the remainder of the period.

Mid term long term (Friday night - Wednesday)
Upper ridging holds from the gulf of mexico, over the state and
bahamas, into the W atlantic through the weekend then slowly sinking
southward next week as an upper level trough moves through the
plains states.

At the surface, W atlantic high pressure holds in place over the
region keeping warm and humid se-s low level flow through the
weekend. A weak front stalls and dissipates north of the area early
next week with another high pressure area moving through the SE and
settling into the W atlantic. Expect well above normal temps with
mainly slight chances of light diurnal showers through the extended
period.

Aviation
All terminals are reportingVFR conditions this afternoon. Latest
obs are showing a bkn ovc layer of CU sc streaming in from the east
at most locations, but conditions are expected to remainVFR with
ceilings around 4-6 kft. East-southeast winds will prevail today
remaining 10 knots or less through the period. No other aviation
impacts expected.

Marine
High pressure ridging over the area will keep pleasant boating
conditions over the gulf coast waters through the period. A
predominant north-northeast through south-southeast wind
flow around 10 knots will prevail with some gusts
approaching 15 knots, but no headlines are expected. A
chance of showers will be possible, but only in the 20-30
percent range. The high shifts south by next Monday, which
combined with an approaching cold front from the northwest
will cause a shift in the winds to the south-southeast, but
still remaining 10 knots or less. No other marine impacts
expected.

Fire weather
Sufficient low level moisture will keep humidity values above
critical levels through the end of the week and into the upcoming
weekend with no red flag conditions expected. Some patchy fog will
continue to be possible during the late night and early morning
hours the next several 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.
