Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
845 AM EST Wed Dec 5 2018

...FREEZING TEMPERATURES POSSIBLE ACROSS THE NATURE COAST
TONIGHT...

.UPDATE...
Noticeably cooler and drier air continues to advect into the
forecast area early this morning on gusty northerly winds.
Ample sunshine is expected the remainder of today as surface
high pressure builds in over the area, but despite the
sunshine cool air advection will keep temperatures from rising
much with highs only reaching the upper 50s to around 60
across the Nature Coast, and lower to mid 60s central and
south with the gusty northerly winds making it feel even
cooler. Current forecast is in good shape with no morning
update required at this time.

&&

.AVIATION...
VFR. North winds 12 to 15 knots with gusts up to 25 knots
will diminish to 8 to 10 knots after 00Z tonight.

&&

.MARINE...
Strong surface high pressure building in over the northern
Gulf and a tightening gradient will maintain a gusty north
to northwest wind flow over the Gulf waters the remainder of
today, with solid Small Craft conditions expected over the
offshore waters and Cautionary over the near shore. Based
on the latest marine observations near shore will add
Cautionary headlines to the Tampa Bay and Charlotte Harbor
waters in the mid morning update, otherwise the rest of
the forecast on track with no other changes planned at this
time. The strong and gusty onshore flow will support choppy
wave action along with a high risk of rip currents at all
area beaches the remainder of today, and a high rip current
risk will remain in effect through early tonight.

&&

.FIRE WEATHER...
Much drier air will continue to advect into the forecast
area the remainder of today. This dry air will support 3 to
5 hours of humidity values below 35 percent over a large
portion of the forecast area during the afternoon. These
low humidity values combined with elevated ERC's and gusty
winds will support elevated fire weather conditions today,
and will need to monitor for the possibility of short fused
Ref Flag conditions during the afternoon. A slow increase in
moisture is expected during Thursday and Friday.
