Discussion
Water vapor and upper air analysis shows plenty of dry air over the
region today with high pressure in place aloft. At the surface, a
cold front is draped across the northern part of the peninsula, with
a low-level east to southeast flow in place across our forecast area.

This boundary will slowly drop southward before stalling across
central florida on Friday. Unfortunately, this front will only bring
some extra clouds and a few showers mainly to areas north of around
the i-4 corridor for today and Friday. Areas to the south will remain
warm and humid, with temperatures nearing record highs.

For this weekend, a trough will dig southward over the eastern part
of the country from canada, suppressing the ridge over florida and
allowing heights over us to fall a bit. Another cold front will move
through the region Saturday night and Sunday, with high pressure and
some drier air briefly filtering into the area. Temperatures will
remain warm on Saturday, but maybe just a couple of degrees lower
than those for Friday and then for Sunday, we will have both lower
dew points and temperatures. Nothing to get overly excited about yet
as this will be brief, but we will take anything at this point.

As we head into next week, some shortwave energy will move along the
northern gulf coast, with increasing rain chances. The surface high
will shift to our east, with an easterly flow in place and
temperatures a degree or two above normal.

Aviation
GenerallyVFR conditions are expected through the forecast period. A
few showers will be possible today, but chances remain too low to
mention in the tafs. Winds will become light out of the east to
northeast tonight into Friday morning, then the sea breeze will turn
winds onshore at the coastal sites in the afternoon. Similar to the
past couple of mornings, we could see some patchy fog at the
normally fog-prone terminals, but nothing that should linger for an
extended period.

Marine
East to northeast winds will persist through the end of the week,
with a weak sea breeze forming near the coast each afternoon. Winds
will generally remain less than 15 knots except for tonight, when
they will increase to near cautionary levels. For the weekend, winds
will shift from south to southwest Saturday to northeast on Sunday
as a cool front moves across the waters. Wind speeds will remain
less than 15 knots Saturday, then increase to cautionary levels
Sunday and then possibly to advisory criteria for a few hours Sunday
night. A light easterly flow will then return early next week.

Fire weather
Relative humidity values will remain above critical levels for the
next several days. Some patchy ground fog is possible in the
typically fog-prone areas late tonight into early Friday morning,
but no significant fog or visibility restrictions are expected.

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.
