Hard freeze with low wind chills tonight...

Update Cold and dry air continues to funnel into the area in the
wake of a strong cold front. Temps are already below freezing across
much of inland SE ga and will continue to fall steadily overnite
from strong cold air advection. MOS guidance still appears too
cold for overnite lows given that winds will be elevated. However
still going with a hard freeze most areas with lows mostly in the
lower to mid 20s. Sustained winds of 10 to 15 mph will produce
wind chills in the teens and a wind chill advisory continues in
effect.

Aviation PrevailingVFR expected.

Marine As a strong surface high moves in across the lower mississippi
valley a locally tight pressure gradient will produce blustery northwest
to north winds resulting in small craft advisory conditions for all
of the waters.

Rip currents: a moderate risk.

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.
