Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
818 PM EST Wed Dec 13 2017

.UPDATE...
A near zonal flow is in place across the region this evening, with
some mid and high clouds streaming eastward into the central Gulf of
Mexico. High pressure remains in place at the surface. For tonight,
this high shifts eastward a bit, allowing low-level winds to become
more southwesterly. This in turn will lead to an increase in moisture
and some additional cloud cover intruding into the northern half of
the forecast area by sunrise. There could also be a few showers
before dawn, mainly across the northern Gulf waters and the northern
Nature Coast region, but this is a fairly isolated chance so will
keep PoPs at 20 percent or less. Other than that, really not a whole
lot going on weather-wise across the local area. Temperatures will
bottom out in the 40s and 50s tomorrow morning, generally a few
degrees warmer than this morning. No major changes needed for the
evening update.

&&

.AVIATION...
VFR conditions are expected to prevail through the forecast period.
Winds will remain out of the southeast, increasing into the 8-10
knot range during the day. Should see a bkn layer of clouds around
5-6k feet develop after daylight, but should remain VFR.

&&

.MARINE...
High pressure over the area will shift eastward through Thursday
night ahead of an approaching weak frontal boundary. Southwest winds
will become more northerly and then northeast Friday and Saturday
behind this front. High pressure will then settle back over the
region for the end of the weekend. No headlines are expected for the
next several days.
