209 pm est Fri feb 15 2019

Short term (rest of today - Saturday)
Aloft - a low over the great lakes moves into southern quebec
while a trough over the bahamas exits east... Allowing zonal flow
to set up over the gulf of mexico region. Surface - atlantic high
pressure extending southwest across fl to the gulf of mexico
slowly drops south but continuing to dominate fl and much of the
gulf. Initially the axis of this high pressure stretches through
northern fl but shifts down to near south of the florida keys.

The atmosphere continues generally stable but does slowly moisten up
with model pwat values climbing into the 1.3 to 1.4 inch range
sat afternoon. The main impact from this increase will be late
night-early morning patchy fog and low clouds. Temperatures will
run on the warm side of normal by a couple of degrees or so.

Long term (Saturday night- Friday)
Zonal flow aloft and surface high pressure from the western atlantic
extending west across the southern peninsula at the start of the
period will maintain pleasant dry weather through Sunday with
warming temperatures. During next week an amplifying upper level
trough over the western southwestern u.S. Will support a building
downstream upper level ridge over the bahamas and florida with the
attendant surface ridge persisting from the western atlantic across
south florida. The building ridge will keep any low pressure areas
and cold fronts at bay well to the north of the forecast area
through the period with warm and increasingly humid conditions
expected under a deep layered south-southwest wind flow. Some
isolated showers (pops 20 percent) can't be ruled out each day along
the sea breeze circulations within the increasingly humid air mass,
but for the most part mainly rain-free conditions are expected.

Temperatures will run some 10 to 15 degrees above normal with lows
in the 60s, with daytime highs climbing to around 80 to the lower
80s along the coast, and mid to upper 80s inland with some near
record high temperatures possible in some locations.

Aviation
15 18z TAF cycle.VFR conditions with ci give way to MVFR mainly
br btwn 07-15z. Then br and any low clouds lift toVFR bkn at 4-5k
ft. SW winds less than 10kt become light and vrb to calm aft 01z.

Marine
Main concern will be fog; patchy land fog is expected later tonight
that may drift across parts of tampa bay; some sea fog will be
possible Sat afternoon through Sun as warm and moist southerly air
flows across cooler gulf waters.

High pressure from the atlantic dominates the gulf of mexico through
the middle of next week with gentle to moderate veering winds. A
cold front or two may approach but not reach the waters.

Fire weather
A dry air mass through the weekend will preclude any low rh concerns
but with enough moisture for patchy late night fog. Moisture will
slowly increase during next week with some low odds of showers as a
couple of fronts approach but not reach the area.

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.
