area forecast discussion
national weather service melbourne fl
241 pm edt Thu aug 17 2017

Discussion
Thru tonight... Boundary driven storms will continue to develop
through mid and late afternoon in the weakly steered environment.

The best chance for deep convection will be across inland locations
where numerous boundary mergers have yet to occur with activity
beginning a decrease past sunset. Locally heavy rain and frequent
lightning will remain the primary storm hazard.

Friday... Ridge axis is expected to become situated a little
further north, which will open up a little earlier onshore flow
conditions for the space and treasure coast. Pcpn chcs will
correspondingly be a little lower across the south on Fri with
another round of scattered storms inland and especially across
orange co. North across lake co and the i-4 corridor.

From earlier discussion...

weekend-next thu... The 00z GFS showed mid level inverted trough
shifting west over the gulf of mexico early in the period, with
ridge building in behind it over florida. Meanwhile, the surface
ridge axis will lift into north florida Sunday, which would
generate an onshore wind flow.

The latest models showed highest moisture values from Sat (in the
south) into Sunday as area comes under east side of the inverted
trough. Lower pops are anticipated Mon as mid level ridge covers
the area. These climo or slightly below normal pops will continue
into mid week, except the northward nudge of the subtropical ridge
may allow for the northern extension of a tropical wave to affect
southern areas Tue into wed. Frontal trough is shown dropping
into the southeast states Thu and suppressing surface ridge back
to the south. This would signal a return to higher than normal
pops for east central florida.

Aviation Scattered to numerous showers and thunderstorms expected
this afternoon and evening primarily north and west of a line from
kism to ktix where tempo groups have been included. Southward only
have vcts for kmlb where some storms could push back toward the
coast this evening. Kvrb, kfpr, and ksua should remain dry.

Shower storm activity should diminish around sunset withVFR
prevailing overnight tonight into early Friday afternoon.

Marine
Through tonight... Onshore winds along the coast becoming light
this evening below 10 kts. Seas 1-2 ft near shore and around 2 to
3 ft well offshore. The greatest chance for offshore moving
afternoon storms should be from about canaveral northward.

Fri... Surface ridge axis is forecast to extend across the central
waters. This will produce a southwest wind flow in the north and
southeast in the south. Speeds look 10 knots or less with
continued rather benign seas. The chance for offshore moving
afternoon storms looks low and mainly from about canaveral
northward.

Weekend-mon... Little change in the models showing axis of surface
high pressure ridge nudging north into the northern waters Sat and
then north of the waters on Sunday. Speeds look 10 knots or less,
except up to 10-15 knots in the south half sun-mon. The more
southeast wind component should bump up seas slightly to near 3
feet offshore and maybe 4 feet by mon. A weak low pressure wave
should increase shower storm coverage in the southern waters sat
and central north waters Sunday. Drier conditions are expected
mon.

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.
