Short term (today - Saturday)
Mid level ridging dominating the gulf region today will begin to sag
southward Sat as a trough moves through the upper midwest and digs
into the ohio valley and deep south. Surface high pressure on the
mid-atlantic coast this morning exits to the atlantic today and
continues moving east through sat... With relaxed ridging extending
back across fl to the gulf of mexico. A warm frontal boundary
across central fl eases north through tonight then begins to
dissipate sun.

Moisture varies across the area from north to south with pwat of
1.5 to near 1.8 inches along and north of the boundary and 1.0 to
1.4 inches to the south. This will keep the best odds of showers and
a few storms over the central and northern counties today then
generally north of the i-4 corridor sat... As the boundary moves north
and weakens sat. Pops stay in the 20 to 40 percent range. Low level
northeast to east flow today becomes more easterly Sat as the
high pressure moves east. However the gradient stays relaxes
enough to allow some afternoon sea breezes. Temperatures continue
to run above normal.

Mid term long term (Saturday night - Thursday)
At mid levels: a trough over the eastern seaboard exits to the
atlantic Mon with a second trough sweeping across the northeast
quarter of the nation late tue-wed. This will keep a ridge
suppressed over and south of the area through the period as a
couple of weak short wave troughs traverse the gulf coast and
north fl. On the surface: high pressure near the upper mid-west
slides east to the atlantic by Mon with a cold front strung out
along the gulf coast settling into central fl during Sun then
south fl mon. The high tracks eastward through mid to late week as
another high pressure area drops into the northern plains from
canada and treks to the great lakes region.

The front moves through early in the period with some showers thunderstorms
and slightly drier and cooler air in it S wake. Temperatures will be
closer to normal. But as the high pressure moves east during mid to
late week the low level flow becomes easterly with moisture and
warmer temperatures gradually returning.

Aviation
19 06z TAF cycle.VFR. Although lal and pgd could see some limited
br this morning. There will be a few shra tsra around but with
low chances of impacting the terminals. Light mainly ene to e
winds become easterly and increase slightly late morning and
afternoon... With a sea bay breeze wind shift at tpa pie srq.

Marine
A relaxed pressure gradient across the waters will keep winds
light to moderate and allow some afternoon wind shifts in sea
breezes. A cold front moves through the area Sun and into south
fl mon... Bringing some showers and storms with increasing winds in
it S wake as high pressure builds in. Winds may reach cautionary
to advisory criteria at times. The high moves east mid to late
week with winds diminishing and veering.

Fire weather
A frontal boundary wandering across the area as it slowly
dissipates over the next couple of day will provide adequate
moisture to maintain minimum humidity above criteria levels and
provide showers storms and some patchy fog. A front tracks south
across the area Sun with showers thunderstorms and drier and
cooler air in it S wake. Humidity values may approach 35 percent
early next week but not drop below.

It is not checked for accuracy either by anyone at L-36.com 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.
