Sunny and chilly with below normal temps today...

Update
Clear skies in light north flow this morning with a light freeze
inland with temps in the lower 30s there with mid to upper 30s
closer the coast. The north winds at 5-10 mph is creating wind
chills in the mid-upper 20s this morning just above advisory
criteria. Freeze warning will expire at 9am with sunny skies and
cold temps today only reaching the upper 40s to middle 50s.

Surface flow will become more northeast through the day as the
high pressure builds down the SE us coastline and this will slowly
push some strato-cumulus clouds over the atlc waters into the ne
fl coastal areas this evening and then across some inland areas
during the overnight hours. This will lead to a more challenging
temp forecast tonight with generally lows in the 30s inland and
40s closer to the coast in the northeast sfc flow around 5-10 mph.

Portions of inland SE ga do have a slight chance of seeing another
light freeze with temps in the lower 30s while other inland areas
will see temps in the mid-upper 30s with some patchy areas of
frost but with low level wind flow remaining up just a bit tonight
do not expect frost advisories to be posted at this time but will
take another look with the guidance this afternoon.

Aviation
Vfr today with NE flow bringing in strato-cumulus deck from the
atlc into the coastal TAF sites tonight, with some chances of MVFR
cigs around 3000 ft at sgj by 06z and rest of the TAF sites by
the 09-15z time frame on Tuesday.

Marine
North-northwest winds will become northeast this afternoon and
tonight as high pressure ridges down the SE us coastline. Seas
will generally remain in the 3-5 ft range for now.

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.
