Discussion
Today... High pressure will consolidate over the southeast u.S. Which
will produce veering wind flow from N NW early this morning to ne-e
by afternoon. Very dry air will remain despite the developing
onshore flow with only some thin cirrus streaming overhead. Over the
interior, MAX temps will be a degree or two warmer with upper
70s near 80. But along the immediate coast, MAX temps will be a
little cooler, in the lower 70s, because of the developing breeze
off the atlc.

A lingering small but long period (11 sec) east swell will produce a
moderate risk of rip currents at the beaches. The threat will be
greatest during the afternoon and early evening, a few hours either
side of low tide.

Tonight... Temps will not be quite as cool as onshore flow gradually
modifies the airmass and forecast model soundings show an increase
in opaque cirrus after midnight. Still, expect seasonable mins in
the mid 50s over the interior. Mins along the coast are trickier. If
the light onshore flow ceases and a light offshore drainage flow can
develop, temps could fall into the mid 50s as indicated by NAM and
gfs mos. Will go a degree or two higher though in the official
forecast given the strength of east winds above the boundary layer
and increasing high clouds.

Sun... Weak shortwave trough crosses the CWA during the day, but
with continuation of dry airmass (preciptable water near 0.75
inch), it will remain rain-free, with only some scattered
daytime cloudiness (following two mostly cloud-free days). High
pressure center works into the western atlantic from carolina
coast, and with ridge axis establishing to our north, east flow
will gradually veer southeast. MAX temps very near climo (upper
70s near 80), except a few degrees below along the volusia coast
(mid 70s) due to onshore flow across cooler shelf waters.

Overnight mins also near normal (upper 50s near 60), except
low mid 60s along coast south of the cape.

Mon-tue... Mostly zonal flow aloft Mon becomes cyclonic Tue as tail
end of longwave trough crosses the state during the day. Low level
ridge drops through and south of region mon, allowing weak frontal
boundary to slowly advance across area tue. Isolated showers
possible far south CWA Mon and across much of area Tue as front
drops southward. More important feature will be post frontal ne
wind surge which develops between strong high entrenched from new
england to the carolinas and marine low which forms near bermuda.

Breezy conditions will develop along the volusia coast Tue night,
bringing scattered showers onshore and inland, with isolated
coastal showers farther south. MAX temps near 80 Mon tue, except
upper 70s along the coast. Tue morning mins similar to mon
morning.

Wed-fri... Nw flow prevails aloft as trough along eastern seaboard
moves offshore and evolves into a deep cut-off cyclone near
bermuda. Moderate to strong NE flow between high pressure wedging
down the us east coast and stationary surface low near bermuda
peaks Wed along entire CWA coast, then slowly abates Thu and fri
while veering easterly. Moisture trapped within tight gradient
flow will bring scattered showers to the eastern half of CWA wed,
lingering overnight across the coastal counties. Isolated coastal
showers still possible Thu fri, but coverage becoming more sparse.

Ne wind shift combined with weak cold advection will drop max
temps about 10 degrees from Tue maxs, ranging from upper 60s
along volusia coast to lower to mid 70s elsewhere. Slow temp
moderate will begin thu, reaching back toward climo fri. Mins
through the period generally mid to upper 50s, except near 60 to
the lower 60s along the coast south of the cape.

Ne wind surge and associated high seas may create high surf and
beach erosion issues along the beaches Wed thu.

Aviation Vfr. Light NW to N winds this morning becoming NE to e
up to 10 knots by afternoon.

Marine
Today... Offshore (w-nw) flow this morning will veer NE during the
day as high pressure consolidates over the southeast u.S. Winds will
maintain a northerly component with speeds 10-15 knots initially
this morning over the open atlc, decreasing to around 10 knots this
afternoon. A caution headline does not look warranted but less than
ideal boating conditions expected ESP in the gulf stream where
choppy seas 4-5 feet will occur, 3 feet close to the coast.

Tonight... Winds will continue to veer and become easterly 10-15
knots. Seas remaining 3 feet nearshore and 4-5 ft offshore.

Sun-mon... Ridge axis north of the waters Sunday, drops south to
the area mon. East wind 10-15 kt sun, veers SE S overnight near 10
kt and continues mon. Wind becomes SW W Mon night in advance of
next front. Seas 3-4 ft Sunday and up to 5 ft offshore, subside
to 2-3 ft all waters Sunday night through Mon night.

Tue..Winds become NW 5-10 kt as weak front moves across waters,
then veers N and NE Tue night, increasing rapidly toward 20 kt
across at least the volusia county waters by daybreak wed. Seas
2-3 ft tue, building rapidly across waters north of the CAPE by
daybreak Wed to 5-8 ft.

Wed... Strong NE wind surge builds down the coastal waters by mid
day. NE wind near 20 kt north of sebastian inlet and 15-20 knots
farther south. Seas respond quickly to long fetch length of strong
ne surge, reaching 6-10 ft (or more) across waters north of
sebastian inlet by mid day and farther south into the afternoon.

Fire weather
Today... Modification of the dry air will begin as winds turn onshore
(ne) by afternoon. So min rh along the coast will hold near 40
percent. But over the interior, long duration of critical rh is
expected once again with min rh values around 25 percent over lake
county and adjacent portions of western orange. With MAX temps
warming into the upper 70s near 80, a few locations in lake county
could see rh near 20 percent. Winds will start out from the N nw
this morning then NE by afternoon with speeds up to 10 mph. Red flag
conditions are not expected.

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.
