Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
817 PM EDT Sat Jun 24 2017

Rather warm mid level temperatures (-4C at 500MB) kept
overall convective development and coverage in check during
the afternoon with only isolated to widely scattered showers
and a few storms being observed. Early this evening 88D
returns show a broken band of showers with a few embedded
storms from western Polk/southeast Hillsborough counties
south to the Fort Myers area along the sea breeze.

A few additional showers or storms may fire off along
existing outflow boundaries during the next hour or so as
the convection moves slowly toward the west, otherwise the
convection will gradually wind down after sunset as boundary
interactions weaken and loss of daytime heating continues
with skies becoming partly cloudy overnight.

It will be a warm and muggy night with lows in the mid 70s
inland areas, and upper 70s along the coast. Will update
the zones to remove evening rain chances in a mid evening
update once most of it ends or shifts west into the Gulf
waters, otherwise no other grid or zone changes are expected
at this time.


Brief MVFR cigs/vsby from shra/tsra will be possible at the
terminal sites through 02Z tonight, otherwise VFR is
expected. West to northwest winds in the 6 to 8 knot range
early tonight will become light and variable after 02Z.
Additional brief MVFR/IFR cigs/vsbys will be possible after
17Z on Sunday as shra/tsra re-develop over the region.
Southeast winds at 4 to 6 knots early Sunday morning will
become southwest to west at 8 to 10 knots after 17Z as the
west coast sea breeze develops and moves inland with higher
gusts possible in the vicinity of tsra.


Surface high pressure from the Atlantic extending west
across the central Florida peninsula will maintain tranquil
boating conditions over the Gulf waters the remainder of
tonight through Sunday with a light southeast to southwest
wind flow expected from south to north with a weak pressure
pattern supporting an enhanced onshore sea breeze component
developing along the coast Sunday afternoon. The current
forecast is in great shape with no changes expected in the
next forecast issuance later this evening.


Gulf waters...None.
