Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
257 PM EDT TUE JUL 12 2016

.SHORT TERM (This afternoon-Wednesday)...
A more typical summertime pattern for the area this week as the
broad upper ridge over the region continues while the weak
relative high center moves from the Bahamas today over the state
then into the Eastern Gulf late Wednesday. Western Atlantic
surface high pressure axis holds over the N FL Peninsula keeping
the C and S FL areas in SE low level flow. Warm, humid and
unstable July atmosphere to combine with diurnal heating and
bay/sea breeze boundaries to produce scattered to numerous
thunderstorms through this evening then again Wednesday afternoon.
Best coverage of storms favor I-75 corridor from the Tampa Bay
area southward into SW FL. Temperature around seasonal normals as
well.

&&

.LONG TERM (Wednesday Night-Tuesday)...
Upper ridging over the state weakens Thursday and flow becomes
more zonal across the area. Surface high pressure will ridge
across the area through the period from the Atlantic with the
ridge axis mainly remaining north of the area. This will keep
generally SE flow in place across the area with an afternoon sea
breeze developing each day. Moisture will increase through the
column as the upper ridge weakens and will allow for scattered
afternoon and evening showers and thunderstorms each day forming
along sea breeze and outflow boundaries. Temperatures will remain
in the lower to mid 90s for highs and in the mid 70s to around 80
for lows.

&&

.AVIATION...
Afternoon through evening thunderstorms continue for brief
MVFR/IFRconditions in/near the strongest cells through about
02Z. VRF conditions returning all sites after that through the
overnight hours.

&&

.MARINE...
Light pressure gradient to hold over the E Gulf waters through
the week with light winds and slight seas continuing. Expect seas
2 ft or less and afternoon seabreezes near the coast with
increased thunderstorms near the beaches and coast that may
produce strong gusty winds that would briefly increase and chop up
seas and contain deadly lightning. So mariners need to always pay
attention the weather for their safety.

&&

.FIRE WEATHER...
Summertime humidity values along with afternoon sea breezes
showers and storms will continue through the week.
