Today will start out with low cloudiness across the suwannee
valley and southeastern georgia which should burn off and lift
into a cumulus deck between 9 and 10 a.M. That low cloudiness may
inhibit destabilization over the nature coast counties with
convection initiating closer to interstate 75 and the florida-
georgia state line later this morning. With more stable
conditions near the altamaha river we should take a day off from
major convection in that area but from about waycross southward we
should see an active day. Mostly clear conditions are evident
south and east of a line from fernandina beach to trenton and this
area will heat up and destabilize rapidly today. Expect to see
heat index values rise into the 103-108 degree range by late
We currently have MAX surface based capes over 5000 j kg over the
gulf and nature coast with some convection over the apalache bay
area. By noon that area will expand to cover the entire north-
central florida peninsula area. 0-3 km storm relative helicity is
only in the 100 to 150 range so not looking at a tornadic day
with the greatest threat likely to be strong down busts.
The main flow will be from the west to the east across the area
with the cells moving east at 20 to 30 mph also increasing
confidence in linear downburst with and ahead of cells. So expect
early convective initiation along the florida-georgia state line
moving east through the jacksonville metro area and over the
coastal waters. The convection will then fill in over most of the
area south of waycross by early afternoon with cells again moving
over the coastal waters.
Showers and thunderstorms will develop near and over almost all of
the fields later this morning and continue through most of the
day. Low ceilings in the 1-2.5 kft range, reduced 1-3sm
visibilities and downburst conditions will be the primary threat.
Wind gusts of 30 to 40 knots in and near convection are definitely
possible with a slight risk of severe conditions at all fields.
Going to be a deceptive day for boaters with conditions looking
good during the morning hours but convective initiation over the
land areas this morning will cover the intracoastal waterway and
coastal waters by early afternoon. Strong possibility of wind gusts
near or above 35 knots with those storms and boaters should be
ready to make for shelter port with short notice today. Not going
to be a good day to be well offshore today. Plan to issue a marine
weather statement for this possibility after completing the afd.
Southwest flow will continue as low pressure develops over
the carolinas and drops southward early next week. Speeds generally
in the 10-15 knot range may increase to cautionary levels offshore
early next week. Offshore moving storms with wind gusts of 35-50
knots will be possible today and possibly on Monday and
mariners boaters will need to be prepared for rapidly changing
Rip currents: low risk today due to offshore flow. Have gone with a
moderate risk NE fl beaches Monday as the flow increases and becomes
onshore in the afternoon.

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.
