Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
228 PM EDT SAT JUL 16 2016

.SHORT TERM...
Over the past few hours, have seen an increase in tstm activity
across the Nature coast; while to the south, east coast seabreeze
activity is gradually increase in coverage/intensity. Over the next
few hours, expecting the activity across the eastern Peninsula to
continue moving slowly to the west as the day progresses. As has
been the case recently, greatest coverage of showers and storms is
expected along and near the I-75 corridor later this afternoon and
into the early evening hours. Weak steering flow remains in place
today so some locally higher rainfall totals can be expected in some
spots. A few stronger storms can not be ruled out with gusty winds,
frequent lightning and small hail possible with the strongest
storms.

The low-level ridge axis will drift north a bit on Sunday but the
east/southeast flow will continue. With no major changes to the
airmass, and ample atmospheric moisture in place, diurnal tstm
activity can be expected the rest of the weekend. Temperatures will
remain above normal into next week with low 90s near the coast, mid
90s inland with heat indices in the 100 to 105 range.

.LONG TERM...
High pressure will build aloft over the south-central part of the
country through mid-week before retreating westward for the end of
the week and into next weekend as a trough extends across the east
coast. At the surface, the Atlantic ridge axis remains generally
north of the forecast area with an easterly flow prevailing.
Overall, not much change to the ongoing longer-term forecast. With
this easterly flow pattern,the best overall coverage will likely be
around the I-75 corridor, with storms shifting westward into the
evening. Hard to put too much detail into summertime rainfall
forecasts, but with plenty of moisture in place along with sea
breeze and other boundary collisions each day, we can expect to see
scattered to numerous showers and thunderstorms each day.

&&

.AVIATION...
VFR expected outside of any showers and storms with E/SE continuing
into Sunday. In the last few minutes, have seen a few small
thunderstorms develop across Tampa Bay which may impact PIE and TPA.
Will send AMD TAFs with TEMPOs if these isolated storms look to
impact the areas. Otherwise, greatest coverage of storms is expected
later this afternoon.

&&

.MARINE...
Tranquil boating conditions are expected over the Gulf waters
through the period with light east to southeast winds and slight
seas expected daily with a weak pressure pattern favoring an onshore
sea breeze component developing along the coast each afternoon. Wind
and seas will be higher in the vicinity of thunderstorms, otherwise
no headlines are expected.

&&

.FIRE WEATHER...
Abundant moisture combined with elevated rain chances from daily
showers and thunderstorms will keep humidity values well above
critical levels with no fire weather concerns expected the next
several days.
