Strong to severe thunderstorms possible Tuesday...
Hazardous marine conditions begin Tuesday...
Short term (overnight)
Weak short wave trough which resulted in showers and a few storms
this afternoon for the nature coast has exited the ga fl coast...
with just some showers in levy that are winding down. Meanwhile a
strong deep low pressure system is moving up the ohio
valley... Trailing a short wave trough with an associated cold
front across the gulf coastal states and the adjacent gulf waters.
Deep southwest and west flow ahead of these features will provide
increasing moisture during the night with patchy to areas of
occasionally dense fog under low clouds. Forecast for tonight
looks good with not updates planned.
The S W trough and front will be approaching the coast around or
shortly after daybreak then traversing the area during the day...
the northern areas during the morning and the southern areas in
the afternoon. Some strong to severe storms will be moving
through with damaging winds the greatest threat... Along with the
potential for some hail. An isolated tornado cannot be ruled out.
Winds increase as the front passes with breezy
conditions... Perhaps reaching lake wind advisory speeds.
20 00z tafs.VFR under increasing mid and high clouds continue
until aft midnight when br and low clouds begin MVFR conditions
but can not rule out LCL ifr... Mainly for cigs. The br and to a
lesser extent the low clouds begin to lift 12z-15z although MVFR
continues for much of the morning. Potent cold front approaches
with shra tsra and few-sct cb... Starting around 12z for the
northern terminal and about 18z for southern ones. Modest
southerly winds continue through the night and into the morning|
then shift to southwesterly with gusts in the 25kt to 30kt range
for the afternoon... But possibly higher near any strong tsra.
Increasing winds tonight reach small craft advisory speeds in the
morning for the northern and middle offshore waters and elsewhere
in the afternoon... And continue at these speed while shifting to
west and northwest through wed.
Very dry air behind the Tue front sweeps in Wed and continues for
the rest of the week... Creating the potential for some red flag
conditions... Depending upon the erc values.

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.
