AVIATION...Lingering convective activity expected to remain over
interior through 02Z, then clearing overnight. Seabreezes will
diminish after 02Z-03Z, with light drainage flow at all sites.
Seabreezes redevelop after 15Z-17Z becoming ESE 8-10kts for east
coast sites and WNW 10kts at KAPF. Can`t rule out a SHRA/TSRA in
the vicinity of KFLL southwards, but most activity looks to be
inland of sites and too low to mention at this time.

PREV DISCUSSION... /issued 351 PM EDT Fri May 26 2017/

Rest of Today: A weakening front over the extreme southern part
of Miami-Dade County is generating a few showers and thunderstorms.
Enhanced moisture and convergence associated with this boundary,
coupled with Atlantic and Gulf sea breezes currently moving
inland, will produce scattered showers and thunderstorms. These
will be mainly over interior portions of the far southern part of
the peninsula through this evening.

Saturday through Tuesday: The front will dissipate late tonight
or early Saturday as deep layer high pressure builds in across the
region. The high pressure will dominate South Florida`s weather
pattern Saturday through Tuesday. We can expect a mostly sunny and
relatively dry Memorial Day Weekend. The only possible exception
would be over the interior during the afternoons, when colliding
sea-breezes could produce an isolated thunderstorm or two. Temperatures
will be hot with highs ranging from upper 80s along the coast to
mid 90s interior, and heat indices will be around 100 degrees.

Wednesday through Thursday: The high pressure will gradually
weaken and move east of the area by mid-week. This will allow
winds to become east-southeasterly, ushering in higher levels of
moisture from the tropics. Shower and thunderstorm activity may
increase for the middle to latter portion of next week.

MARINE...Isolated showers and thunderstorms are possible through
tonight for Atlantic waters off Miami-Dade County. After that,
relatively benign marine conditions will prevail through the
middle portion of next week.
