735 pm edt Tue mar 20 2018
Aviation [through 00z Thursday]
Vfr conditions will prevail through the taf, though a scattered to
brokenVFR deck is forecast to spread across the region overnight.
Gusty winds will continue through the night, though not as intense
as this afternoon. Tomorrow will feature another day of winds
gusting between 20-30 knots.
Prev discussion [347 pm edt]
Short term [tonight through Thursday night]
The cold front is pushing to the south and east of our area this
afternoon and all convection has ended. Gusty northwest winds in
the wake of the front will diminish shortly after sunset. Overnight
lows will dip into the lower to mid 40s. Wednesday will be sunny,
breezy, and cooler than normal with highs in the mid 60s to
around 70. Wednesday night winds will be light under clear skies
with lows dropping into the upper 30s. Sunny skies again on
Thursday with light winds as high pressure settles over the
region. High temperatures will be in the 60s to lower 70s with
lows Thursday night around 40.
Long term [Friday through Tuesday]
After a cool start on Friday, a gradual warming trend will begin
with temperatures warming at or above seasonal levels through the
remainder of the period. A backdoor cold front will approach
Sunday bringing a slight chance for rain to our northernmost zones
Sunday into Monday. Otherwise, it will be dry until at least Tuesday
when a stronger cold front approaches from the west. Temperatures will
be near seasonal levels.
Winds have increased rapidly across the local waters behind today's
cold front. Winds to gale force, mainly in gusts, are expected over the
marine area through late tonight. Then, an extended period of advisory
level winds and seas will continue through Wednesday night. Thereafter,
high pressure builds over the marine area as light winds and generally
low seas returns.
Critical relative humidity levels are expected over the next
couple of days, with gusty winds tomorrow. However, the rain has
lowered fuel moisture indices enough to preclude red flag
conditions. Still, caution should be used as dispersion indices
are forecast to be quite high over the next couple days.
Recent rains have resulted in some notable rises on area rivers in
north florida, though with many starting this event so low,
flooding is not anticipated at most river points. The steinhatchee
river bears watching over the next 36-48 hours. Significant rains
in southeast lafayette county have led to sharp rises on the
river at us-19, which may approach minor flood stage late tonight
and into Wednesday.

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.
