317 am edt Wed apr 26 2017

Short term (today - Thursday)
A mid level ridge of high pressure over florida and the
southeastern CONUS today will gradually shift east into an
atlantic through Thursday as a broad trough swings through the
southern mississippi river valley. At the surface, atlantic high
pressure ridging across the southern and central portions of the
florida peninsula will edge slightly east on Thursday, keeping dry
and stable conditions in place with rain chances remaining
minimal. Temperatures today are expected to be fairly seasonable,
with highs around 80 along the coast, and in the mid 80s inland.

As the surface ridge slides east on Thursday, mean low level winds
will become increasingly southerly, leading to a hotter and more
humid airmass. Highs on Thursday are forecast to top out in the
mid to upper 80s along the coast, and in the low to mid 90s
inland.

Long term (Thursday night-Tuesday)
Period will begin with a deep u/l trough over the western half of
the country with a strong u/l disturbance digging near the four
corners area Friday night... Shifting east to the southern plains
late Saturday and Saturday night. This will help pump up a strong
u/l ridge over the western atlantic and florida with building
heights and increasing large scale subsidence over the forecast
area. The strong u/l disturbance will lift rapidly northeast
across the mid missouri valley Sunday to the western great lakes
on Monday. The associated u/l trough will approach the eastern
seaboard Monday night and Tuesday... But the u/l ridge over the
western atlantic and florida will be difficult to supplant with
quasi-zonal u/l flow developing across north florida along the
southern extreme of the filling l/w trough.

At the surface, an extensive area of high pressure over the central
and western atlantic will extend across the florida peninsula and
eastern gulf of mexico Friday night through Sunday night. Increasing
deep layer subsidence associated with the building u/l ridge will
allow temperatures to run 5 to 10 degrees above climatic normals
with high temperatures in the mid 80s near the coast to lower 90s
inland. The ridge axis will remain north of the forecast area with
increasing southerly flow over the region. A cold front, associated
with the system near the great lakes, will approach the forecast
area on Monday with an increasing chance of showers and possibly
thunderstorms. GFS is more aggressive with the cold front pushing
across the region Monday and Monday night stalling across south
florida on Tuesday. Leaning toward the ECMWF solution which does
not push the front as far south, stalling it across north florida as
it becomes parallel to the u/l flow. With this solution, shower
activity will decrease as it approaches west central florida due to
decreasing u/l support and weakening low level convergence which
would lead to lower pops across the forecast area.

Aviation
Vfr conditions are expected to continue through the next 24 hours.

Ceilings of 4000-5000 feet moving east into the coast will hold
overnight, but should scatter out during the early morning hours.

Marine
High pressure will continue to ridge across the area through the
rest of the week, with winds remaining around 15 knots or less.

The pressure gradient will begin to tighten Saturday night ahead
of an approaching frontal boundary, with periods of cautionary
level winds possible through the early part of next week.

Fire weather
High pressure will continue to hold across the area through the
rest of the week, with dry conditions continuing. Brief
durations of relative humidity less than 35 percent will be
possible each afternoon, but are not expected to last long enough
to produce red flag conditions.

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.
