Discussion
Near term /through 6 am Monday morning/...

as of 300 pm edt... Plentiful low-level moisture continues to move
across the region in a brisk east/northeasterly flow, helping to
promote periods of scattered showers across the region. The 12z
observed kmfl sounding indicated some instability, around 500 j/kg,
present which may lead to some brief heavy downpours with the
heaviest showers. The formation of the gulf sea breeze late this
afternoon and early evening will also provide a focus for additional
shower activity along the gulf coast and interior, and cannot rule
out a few rumbles of thunder where coastal convergence is maximized.

For tonight, scattered showers streaming in off the atlantic will
continue to remain possible, mainly affecting eastern areas although
coverage should begin to gradually wane as the night progresses. The
easterly flow will also begin to weaken tonight as well. Low
temperatures will range from the upper 50s to upper 60s, coldest in
the interior and warmest in the east coast metro.

Short term /6 am Monday morning through Tuesday night/...

high pressure and increasing upper-level heights will build across
the region for early in the week. These features will allow for the
east/northeasterly flow to continue to slowly subside and eventually
become southeasterly by late Tuesday. Meanwhile, drier air and
lowering inversion levels associated with the high pressure will
move into the region, with generally dry conditions expected outside
of a brief light shower across eastern areas.

Highs Monday and Tuesday will generally be in the 80s with lows
Monday night ranging from the upper 50s to upper 60s. Lows Tuesday
night will generally be in the 60s, with a few upper 50s reading
possible in portions of the interior.

Long term /Wednesday through Saturday/...

the long term period will feature tranquil and dry weather as high
pressure continues to dominate. The next major weather feature looks
to occur late Friday and into the weekend as a frontal boundary
approaches the region. This frontal boundary looks to be the next
chance for possible widespread rainfall across the region. With a
southeast/east flow in place, temperatures will be above normal with
highs in the low to mid 80s for eastern areas, and upper 80s to near
90 for portions of the interior and gulf coast. Lows will generally
be in the 60s.

Marine
Winds will continue to gradually subside over the next few days as
high pressure builds into the region, with a return of good boating
conditions. The flow will initially be east/northeasterly, but
gradually become southeasterly by late Tuesday generally 15 knots or
less. Seas will be 4 feet or less into the midweek period.

The next marine concerns may begin Friday as southeasterly flow
strengthens to 15-20 knots ahead of an approaching frontal
boundary.

Beach forecast
A high risk of rip currents will continue for the atlantic beaches
through this evening with a continued brisk easterly onshore flow.

The onshore flow will continue to gradually subside tonight and into
Monday, with the risk of rip currents decreasing to moderate for the
atlantic beaches on Monday. The rip current risk will continue to
decrease further heading into midweek.

Aviation
Streamer has persisted over broward county into early afternoon
so will hold onto vcsh for those terminals through around 20z.

Gulf breeze arrival appears imminent for kapf, so vcsh in place
along with 1830z windshift to west.VFR conditions will prevail,
but cant rule out some brief restrictions associated with showers
until all activity ends after sunset. Aside from naples
aforementioned windshift, east wind around 10-12 kt today will
diminish to 5 kt overnight then increase to around 10 kt Monday
mid-morning.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
