Freeze warning expanded
Update (overnight through early Thursday morning)...

late afternoon high resolution guidance members are adding
increased confidence in a full swing of the winds to a more
northerly or even slightly northeasterly direction during
the second of tonight. If this verifies, there is little
reason to believe that in an advection event such as this,
and given the nearby downstream temperatures already in the
forecast, that colder temperatures (dropping to around
freezing or slightly below) will not eventually make their
way into portions of northern pinellas, coastal manattee,
coastal sarasota, coastal charlotte, and interior lee
counties. Obviously every location in these zones will not
reach freezing... Especially some immediate shore locations,
and much of southern pinellas county, where at least some
fetch of flow off the waters is unavoidable. However,
confidence is now high enough in sufficient areal coverage
of freeze criteria to add these zones to the current freeze
warning. Hazard statement (npwtbw) has been issued, forecast
grids have been updated, and zfp will be issued shortly.

Although some colder temperatures have been added to these
areas above, and wind chills later tonight are now a couple
of degrees colder, wind chill advisories were already in
effect and these areas, and the changes do not impact or
change this hazard.

In addition... Although Thursday night will not be quite as
cold as tonight... It will still be well below normal. The
area of potential freezing temperatures will shrink
considerably from what is in place tonight, but portions of
the nature coast will not escape one additional night of
freezing temps. Have gone ahead and issued a freeze watch
for levy citrus sumter hernando and inland pasco county from
12am Friday through 9 am Friday.

Once this potential freeze is over... Temperatures really
begin to moderate. Temperatures warm very quickly this
weekend... And a lot of the region is expected to see
temperatures back up into the upper 60s to middle 70s by
Sunday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
