Update (rest of today through Sunday)
14z water vapor and h4 rap analysis shows a pattern already
set up to support a benign weekend forecast for the entire
area. Harmless upper level shortwave is exiting our region
this morning... Followed by mid upper level high pressure
building expanding east NE overhead from the gulf of
mexico. This upper level ridging will be in control of our
weather through the duration of the holiday weekend. Very
dry representation on WV imagery was confirmed by the 12z
raob. Once again a very dry troposphere was sampled through
the entire column. The measured pw this morning was only
0.62". To put that into perspective for the 27th of may in
central florida, the 10th percentile value for today is
1.01" and the lowest value every sampled for today is 0.57".

This puts today's pw well below the 5th percentile of
values. Basically... The atmosphere over our heads is dry.

With the lack of moisture and no synoptic forcing to speak
of, it is no wonder our skies are clear this morning. Other
than some passing thin cirrus tonight or Sunday, the pattern
will continue to suggest mostly clear skies right through
the weekend.

At the surface... The subtropical ridge axis lies directly
across the central or south-central fl peninsula and into
the eastern gulf of mexico. This ridge axis will not move
much through the weekend. The ridge axis in the vicinity
means winds and gradient flow are weak... And will be
dominated by sea and land breeze circulations during the day
and night respectively.

Today tonight... As mentioned above, generally benign weather
conditions with warm seasonable temperatures and near 0%
chance of rainfall. Only concern with the current weather
has to do with the forestry fire weather community, as
relative humidity values will be rather low this afternoon
away from the moderating influence of the sea-breeze. Based
on our morning raob, once we mix the boundary layer to
between 900-950mb, we will mix down some very dry air just
above the surface. It will not take very long to reach this
level given the time of year and near 100% of possible
insolation. Therefore, an extended period of sub-critical
level relative humidity is forecast for inland areas.

High temperatures by mid-afternoon should be in the lower
90s away from the coast and middle 80s at the coast. Low
temperatures tonight looks seasonable also, with middle to
upper 60s common inland and lower to middle 70s at the
beaches.

Sunday... More of the same, under plenty of sunshine.

High temperatures are likely to be a degree or two warmer,
but so will dewpoints. Therefore, it will begin to feel a
bit more humid for those with outdoor activities planned.

Have a fun and safe Saturday everyone!

Aviation (27 12z through 28 12z)
Benign aviation forecast through the TAF period for all
terminals. Continued dry atmosphere will keep skies mostly
clear... With only a few passing cirrus at times later in the
forecast period. Winds light and variable early this morning
will shift onshore w-wnw 8-12 knots this afternoon... With
sea-breeze progressively moving inland after 17z. Winds
diminish and become light and variable once again a few
hours after sunset. Some slight potential for shallow MVFR
type ground fog toward dawn Sunday for klal kpgd, however,
confidence still low enough to exclude mention with current
tafs.

Marine
High pressure will be the dominant player in our weather
across the eastern gulf of mexico through the next several
days. The pattern will keep winds and seas generally low.

Only gusty conditions will occur near the coast each
afternoon as the daily sea-breeze develops and migrates
onshore.

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.
