Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
241 PM EDT Thu Sep 6 2018
.SHORT TERM (Tonight-Friday)...
Surface high pressure weakens as an upper low moves over
the state for Friday. This will allow for lighter easterly
flow with an afternoon sea breeze developing along the
coast, and some additional upper energy to enhance
thunderstorm coverage Friday afternoon. Scattered to
numerous showers and storms will be possible. Highs will be
in the upper 80s to lower 90s, and lows will range from the
lower to mid 70s inland to the mid to upper 70s near the
coast.
.LONG TERM (Friday Night - Thursday)...
A weak upper level low will be drifting west and situated
across the Florida Peninsula at the start of the period.
Under strong easterly flow, showers and thunderstorms should
quickly move west off the coast and dissipate tomorrow
night. Low level flow will eventually weaken and turn to
more southwest/variable due to a trailing frontal boundary
from the remnants of Gordon slowly pulling away from the
Mississippi Valley. Drier air will also help to lower our
rain chances some into the early part of next week, compared
to this weekend. An upper level trough may enhance activity
on Tuesday across southern areas but this feature will be
influenced by the exact position of Hurricane Florence.
The threat of Florence having direct impacts somewhere from
the Carolinas northward is increasing. With that said,
there is no indication this system will have any affect on
our weather here in West Central Florida. There are a couple
other waves moving off the African Coast that likely
develop in the coming days and will require monitoring over
the next week. However, it is critically important to
remember that models fluctuate considerably from run to run
and 10 to 14 days out is substantial in the tropical
forecasting world. Be prepared regardless, especially as we
enter the climatological peak of hurricane season.
&&
.AVIATION...
Prevailing VFR conditions under light E to ENE winds.
Numerous SHRA/TSRA are developing this afternoon as they
push west across the Peninsula and these will produce tempo
MVFR with possible IFR restrictions along with gusty winds
as they pass through. Improving conditions after 02Z with
similar scenario expected tomorrow.
&&
.MARINE...
Easterly flow weakens through the weekend, with diurnal
circulations dominating the flow. Winds then becoming more
southerly for early next week, though also have increasing
uncertainty as to how much the ridge holds across the area.
Scattered thunderstorms will still be possible each day,
increasing winds and seas near the storms. No other
headlines expected through the period.

.FIRE WEATHER...
No concerns.
