Hot and dry conditions for memorial day... .

Update
Late morning surface analysis depicts high pressure (1018
millibars) centered over the southeast gulf of mexico, extending
eastward across south florida and into the western atlantic
waters. Meanwhile, a stalled frontal boundary extends from coastal
texas northeastward through the lower mississippi, tennessee, and
ohio valleys. Aloft... Deep layered ridging prevails over our
region and is centered over the bahamas, while a trough was
deepening over the western great lakes and digging southward
through the upper midwest. A large mesoscale convective system
(mcs) generated along the frontal boundary over texas has pushed
into the western gulf waters, with convection on the edge of this
mcs redeveloping over the western florida panhandle and southern
alabama. Debris clouds from this convection are invading our skies
from the west, resulting in filtered sunshine. Earlier low stratus
over north central florida is lifting into a cumulus field.

Temperatures were quickly rising into the mid to upper 80s as of
15z, with dewpoints ranging from the upper 60s to the muggy mid
70s.

The morning sounding at jacksonville revealed a very dry low level
air mass, with a dewpoint depression of nearly 10 degrees c at 950
millibars (2,000 feet). There is moistening to our west, as
tallahassee's sounding had a 5 degree dewpoint depression at 950
mb. High resolution short term guidance suggests that convection
developing along outflow boundaries originating from convection
over al and the fl panhandle will be sparse this afternoon due to
the dry and suppressed environment over our region, compliments of
ridging aloft. A few isolated storms may be possible late this
afternoon between waycross and the i-95 corridor as these outflow
boundaries collide with the atlantic coast sea breeze. The sea
breeze should develop at area beaches around noon today due to a
looser pressure gradient than yesterday, and this sea breeze
should push inland past the i-95 corridor during the late
afternoon hours. Temperatures will still climb to around 90 at
the beaches before this sea breeze pushes inland, with mid upper
90s expected inland. Dry air mixing down to the surface will
result in dewpoints falling to the 60s, which will keep heat
index values in the 100-103 range inland.

Aviation
Vfr conditions will prevail at the regional terminals through at
least 06z. The atlantic sea breeze will develop around noon,
resulting in winds shifting to an easterly direction at sgj by
17z, with onshore winds reaching ssi by 18z, crg by 19z, jax by
20z, and vqq towards 22z. Patchy fog will develop inland tonight,
with MVFR visibilities expected to develop after 08z at gnv and
vqq.

Marine
High pressure extending from the western atlantic into the
southeast gulf of mexico will slowly lift northward during the
next few days, but will remain centered south of our waters. This
will create light offshore flow during the overnight and morning
hours, with the atlantic sea breeze developing around noon over
the near shore waters and pushing inland each afternoon.

Meanwhile, a weak frontal boundary will approach the southeast
georgia waters from the northwest on Tuesday afternoon. Showers
and thunderstorms will gradually increase in coverage each
afternoon and evening, with activity most likely impacting the
near shore waters during the late afternoon and evening hours,
progressing into the offshore waters during the late evening and
overnight hours. Strong to isolated severe thunderstorms will be
possible, with damaging wind gusts and frequent lightning strikes
being the primary threats. Outside of thunderstorm activity, a
weak local pressure gradient will remain in place and will result
in mostly light wind speeds into next weekend.

Rip currents: low risk expected through much of this week due to
mostly flat seas. Sea breezes will develop each afternoon with
breezy conditions developing at area beaches, but low wave heights
will not create a large-scale elevated risk.

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.
