Area Forecast Discussion
National Weather Service Melbourne FL
246 PM EDT Sat May 27 2017


...Sunny, Dry and Hot this Memorial Day Weekend...

Tonight-Sunday...Axis of high pressure ridge across the area will
settle a little to the south. This will generate a light
south/southwest wind flow tonight and with the low afternoon dew
points experienced, min temps will continue a little below normal
in the mid 60s over most of the area.

Though there was a little stratus and ground fog early this morning,
think that sunny/hot/dry afternoons like today will start to be an
inhibiting factor for early morning low clouds or fog.

The settling surface ridge will cause a little more westerly
gradient wind Sunday, which will delay the east coast sea breeze
slightly. This, combined with mid level ridge building from the Gulf
across the peninsula, point to warmer temps along the coast.  A few
coastal sites could approach the mid 90 temps that interior sections
will continue to experience. Precipitable water around 1 inch or
less will lead to another sunny day, though with the mid level
ridge/subsidence, it will probably be a bit hazy.

Sunday Night...500 mb ridge will continue from the ern Gulf over
central FL. At the surface, high pressure will extend from the
Atlantic across south FL. Continued mostly clear with min temps
modifying to around 70 degrees.

Monday...Mid level ridge over central FL in the morning will move
east into the Atlantic in the afternoon. Westerly low level winds
will continue with a very dry airmass in the H8-H3 layer. The east
coast sea breeze will move slowly inland through the late afternoon
and early evening. It will be hot with high temperatures again in
the lower 90s near the east coast and mid 90s for the interior.

Tuesday...As the mid level ridge shifts gradually offshore into Tue
afternoon a weak shortwave will approach the southeast states into
late afternoon. At the surface, light southerly winds are forecast
in the morning becoming southeast in the afternoon as the east coast
sea breeze moves inland. Models indicate enough low level moistening
to continue a low mid to late afternoon afternoon shower/
thunderstorm chance across the interior with late day sea breeze
interactions expected across the nrn interior zones. Highs lower 90s
coast to mid 90s interior.

Wed-Sat...The mid level ridge east of the area on Wed will be
displaced south and east through late week as a more zonal mid level
flow pattern develops over east central FL. At the surface, high
pressure across the Atlc should keep a south to southeast low level
wind flow regime across the area. Models continue to gradually
increase moisture levels into late week and the early part of the
weekend with shower/thunderstorm chances generally in the 20-40
percent range Wed increasing to 40-50 percent into late week. The
inland moving east coast sea breeze should focus much of the late
afternoon coverage across the interior each afternoon. Highs in the
upper 80s to around 90 coast to 91 to 94 degrees across the interior.


.AVIATION...VFR with variable winds across the area. Inland terminals
could have MVFR early Sun morning with haze/BR developing.


Tonight-Sunday...Axis of high pressure ridge will shift south and
provide a south to southwest gradient wind.  Speeds look mostly 10
knots of less, except in the northern waters tonight where 10-15
knots are forecast.  Seas will continue benign near shore at 1-2
feet and possibly reach up to 3 feet well offshore north of Cape

Sunday Night-Monday...The remainder of holiday weekend boating
forecast looks good with prevailing offshore flow becoming onshore
near the east coast each afternoon and evening with the east
coast sea breeze. Seas will average 1 to 2 ft near shore and up to
2-3 ft well offshore.

Tue-Wed...S/SE flow to around 10 knots into mid week and seas to 2-3
ft are expected. Isolated storms may affect the near shore waters by
Wed afternoon and evening.


Sunday...Surface ridge sliding a bit south will generate a little
more west/southwest gradient wind. MOS doesn`t show RH values as
low as the past couple days, but with mid level ridging building
across the area, continued subsidence should produce a little more
of a dew point crash in the afternoon than guidance is showing.
Lowest RH (30 to 35 percent) is forecast over southern areas
where soil moisture is higher, and with durations looking too
marginal, not planning on a Fire Weather Watch.
