Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
943 AM EST Thu Jan 18 2018

.UPDATE...
The day has started off very cold across the forecast area, with
widespread temperatures of freezing and below. Some spots have
experienced their lowest temperatures in years. Tampa hit 29 this
morning, which tied the record low back in 1981. Both of the airports
in St. Petersburg recorded temperatures at or below freezing for the
first time in since 2008 for SPG and 2011 for PIE and the NWS office
here in Ruskin fell all the way to 27. The last time it was 32 or
less was 32 in February of 2015. Temperatures as of 9 am have started
to go up and so the Hard Freeze and Freeze Warnings have both been
allowed to expire. The Wind Chill Advisory is good for another hour.

For the rest of the day, surface high pressure will settle in over
the southeast, keeping a north to north-northeast cool wind in place.
Skies will be mostly sunny, but high temperatures today will only top
out in the upper 40s to upper 50s. The ongoing forecast handles today
well so no update is needed this morning.

.AVIATION...
VFR conditions are expected to prevail through the forecast period.

&&

.MARINE...
Strong northerly winds across portions of the Gulf waters this
morning will continue to diminish through the next several hours with
no headlines in place by this afternoon. High pressure will remain
over the region through the next couple of days, with lighter winds
in place through the weekend. Another cold front will approach the
waters early next week, with winds becoming more southerly. Patchy
sea fog may occur ahead of this front as moisture increases.
