Synopsis..High pressure across the waters will produce benign winds and seas through Thursday. A weak cold front will move in from the north tonight, with high pressure filling back in from the north behind the front bringing increased northeast to east winds. Another cold front will move in late in the weekend, with increasing rain and Thunderstorm chances. This pattern will lead to building winds through the weekend, with periods of cautionary or advisory level conditions expected.

Short term (today through Friday)
Surface high pressure stretched east to west across the florida
peninsula will drift south today with a general westerly flow
setting up ahead of weakening cool front. This front will move south
into the forecast area tonight and Friday with the only real affect
being some clouds. The boundary will wash out across the region
during Friday with another area of high pressure well to the north
building south shifting low level winds back to northeast which will
bring some slightly drier air back into the area. As for
temperatures today we'll see a wide range from mid 70s close to the
gulf coast to the middle and upper 80s inland east of interstate 75
thanks to the westerly flow. Tonight some clouds are expected to
move into the region in the vicinity of the front with lows ranging
from the mid 50s north to mid 60s near the coast from around tampa
bay southward. For Friday northeast winds will setup from around the
interstate 4 corridor northward with some slightly cooler and drier
air moving into these areas keeping temperature in the mid 70s to
lower 80s. Further south lighter north to northeast winds will allow
the west coast sea breeze to develop setting up a range from the
upper 70s near the coast to the upper 80s inland.

Mid term long term (Friday night through Thursday)
As we head into the upcoming weekend, a rather benign weather
pattern will remain in place. Broad, somewhat flat upper flow will
continue as surface high pressure remains anchored north of the
region. With time, this pattern will change, resulting in unsettled
weather heading into next week.

Shortwave upper ridging and surface high pressure will persist into
Saturday, with highs in the upper 70s to mid 80s and a few showers
across mainly interior parts of the peninsula. The upper pattern
will transition early Sunday, as a strong upper trough moves across
the central gulf coast states. This system will nudge closer to our
area Sunday into Sunday night, with substantial increases in rain
chances, especially across the northern peninsula and panhandle, and
interior portions of the state.

Heading into next week, the upper trough will become somewhat cutoff
from the upper flow, allowing it to drift across the region. This
coupled with several weak areas of low pressure emanating from the
gulf of mexico, will continue to promote unsettled weather with rain
chances each day. Light westerly flow will favor early day showers
along and near the coast, with late day showers and perhaps an
isolated storm east of i-75. Given the increase in cloud cover and
moisture, high temperatures will be somewhat limited, remaining in
the 70s and lower 80s.

Drier weather will eventually resume beyond mid week as upper
troughing lifts northeast and a zonal to northwest flow pattern
becoming established. Weak surface high pressure will slip in along
with drier air, allowing for warm afternoons and slightly cooler

Vfr conditions will prevail into early tonight, then some areas of
MVFR ceilings and visibilities could develop as the weakening
front moves into the region. Westerly winds today will increase to
9 to 13 knots this afternoon then diminish to around 5 knots and
shift to north to northeast tonight.

Westerly winds will shift to north to northeast tonight and
increase to near exercise caution criteria across the northern
waters overnight. The breezy northeast winds will persist across
the northern waters Friday with lighter winds further south
allowing a shift to onshore with the sea breeze near the coast
during the afternoon. Friday night an evening surge will move
across the waters with breezy northeast to east winds setting up
and continuing into Saturday. The breezy conditions will persist
Saturday night into Sunday with a shift to a more east to
southeast direction during this time. Early next week a cold front
will approach from the north with southerly winds shifting to

Fire weather
Relative humidity values could dip into the mid 30s across
portions of the interior counties this afternoon and then over
inland areas south of the interstate 4 corridor Friday afternoon.

Otherwise relative humidity values are expected to remain above
critical levels over the weekend and into early next week with no
red flag conditions anticipated.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
