939 am est Tue feb 20 2018
Record warmth expected across inland locations today. Strong high
pressure northeast of the area will maintain a light onshore flow
today. Fog stratus across inland southeast georgia is in the
process of lifting and mixing out. Scattered to perhaps at times
broken cumulus field will quickly fill in this morning and then
scatter out behind the seabreeze as it moves well inland this
afternoon. A few isolated light showers sprinkles possible in
moist onshore flow but the bulk of the area will remain rain free
today. The main update was to increase MAX temps by a few degrees
with mid to perhaps a couple of upper 80s possible well inland
Record temps for february 20:
jax: 86 in 1961
gnv: 85 in 1929
amg: 83 in 2014
ssi: 76 in 1956
Vfr conditions will prevail through tonight. Could see some
reductions in fog late tonight but confidence is rather low at|
High pressure northeast of the region will remain firmly in
control. East southeasterly winds less than 15 knots will
continue. The forecast is in good shape and no changes are needed
Rip currents: moderate risk in onshore flow.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
