Much colder tonight with patchy frost inland...

Update
Moderate cold advection will continue through Friday with temps
averaging well below normal. Tonight, areas of lows clouds
affecting west and northwest zones and along the coastal areas
will shift eastward and slowly erode through later tonight with
clear skies expected most locations by about 2 am. Winds still
expected to stay up around the 4-8 mph range so with lows expected
in the mid 30s to lower 40s, wind chills expected to drop to the
lower to mid 30s with a few upper 20 wind chills possible from
alma northward. Based on latest guidance, with winds staying up a
bit and the current clouds over inland southeast ga, will maintain
patchy frost and not go with a frost advisory for the coldest locations.

For the update, adjusted clouds over the NRN zones to go with
slower improvement there, and placed patchy frost a little
further east.

vfr after midnight for terminals. Northwesterly winds at or below

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
