area forecast discussion... Correct paragraph 3
national weather service melbourne fl
348 am edt Tue sep 26 2017

Discussion
The local map features a very light gradient with a sfc col
analyzed over central fl this am. Deeper moisture remains confined
over S fl, south of a weak sfc trough from near lake okee to N of
grand bahama. Some light marine showers near this feature will
remain into today. Mentionable rain chcs will remain isold over
the SRN forecast area as forcing appears only modest at best
during the heat of the day due to marginal sb instability and
boundary interactions setting up during the aftn. GFS mos guid has
been a little on the high side the past couple days and have
undercut this by a category.

Temps will warm into the l-m90s across inland sites with u80s
along the immediate cst. A few lingering evening showers wl remain
possible across the treasure cst and lake okee regions where
better moisture in the presence of the decaying boundary remain
in place. Lows will fall into the 70s.

A rip current statement will be in effect once again today through
the daylight hours due to swell from distant hurricane maria.

Wednesday-Thursday... Most areas expected to remain dry during the
middle of the week; however, a tight moisture gradient will exist
across south florida, close enough to warrant a low chance (20%) for
afternoon and early evening showers across okeechobee county and the
treasure coast. Ample sunshine will allow high temperatures to climb
several degrees above their late september averages, even along the
coast where light westerly flow will warm temps to 90-92 before the
sea breeze provides some mid late afternoon relief. Would not be
surprised to see a few sites flirt with their record highs given the
latest MOS numbers.

Friday-Monday... A cold front will push through the southeast late
this week, weakening as it approaches north florida by Saturday.

Guidance indicates a surface trough or closed low developing
offshore, though there exists considerable model spread as to both
the strength and placement of the feature. Regardless, a period of
building onshore flow is advertised this weekend with steadily
increasing moisture and pops. Have capped precipitation chances at
50%, though this may need to be adjusted upward should the
trough low move over the area. Increased cloud cover and developing
maritime flow will drop temperatures from their mid-week highs with
mid-80s (coast) & upper-80s (inland) expected.

Aviation
Vfr conds will be primary with isold shra and MVFR conds ascd
with isold shra mainly along the coast this morning S of kmlb-ksua
through 26 17z then isold shra and spreading to both inland and
coastal sites fm 26 17z-26 23z. BecmgVFR areawide aft 27 02z.

Marine
Today and tonight... Lingering long period swell will pose hazards
for small craft with sig waves of 5-7ft mainly ascd with swell
near the coast and 7-9ft offshore today. Breaking waves will
present additional hazards near jetties and inlets. Headlines for
advisory will shift to the outer and gulf stream segments by
tonight with caution nearshore later today and into tonight.

Wed-sat... Long-period swells from hurricane maria will be slow to
subside from mid to late week. Seas 4-6 feet Wednesday will lower to
3-5 feet through the remainder of the period. Weak pressure gradient
remains in place through Friday with winds at or below 10 knots.

Onshore winds begin to increase on Saturday. Abnormally dry air will
keep precipitation chances quite low through at least Thursday,
before scattered lightning storms return to the forecast late this
week.

Hydrology
A river flood warning remains in effect for the st johns river
near cocoa, above lake harney near geneva, near sanford, near
deland and at astor.

River levels remain high over the middle st johns river basin,
with all forecast points above flood stage. The river stage near
cocoa, and above lake harney near geneva will begin a gradual
decline through the end of this week. The river stage near
sanford, near de land, and at astor are forecast to remain steady
with some very gradual decline from the middle to through the end
of this week.

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.
