Short term (tonight-Sunday)
The upper-level low spinning along the northern gulf coast today
will slowly shift westward tonight and tomorrow, with florida
remaining on its eastern periphery. At the surface, high pressure
will remain centered north of the region through tomorrow as
hurricane maria continues to move northward to the east of the
state. This will keep a low-level east to northeast flow across the
forecast area through the end of the weekend. This flow should be a
bit lighter tomorrow afternoon, with more of a west coast sea breeze
allowed to form. With precipitable water values forecast to remain
close to those for today, we can again expect to see a scattering of
showers and thunderstorms, generally moving toward the coast. High
temperatures will run in the upper 80s to low 90s.
Long term (Sunday night-Saturday)
An amplified upper level pattern continues over the CONUS with deep
troughing extending over the western half of the u.S. Closer to
home, ridging extends over the east coast. This ridge is helping to
steer hurricane maria and keep it off to the east of the eastern
seaboard. On the surface, high pressure will remain in control of
the weather across the florida peninsula. In the western atlantic,
hurricane maria continues to make her way northward. Models continue
to take this storm to the north and maria is not expected to pose a
threat to the florida peninsula. With high pressure over the region
for the next several days, rain chances will be on the low side (10-
30%) pops with seasonal temps expected.
Scattered showers and thunderstorms generally moving westward toward
the terminals could lead to brief vis or cig restrictions through the
rest of the afternoon and evening, but otherwiseVFR conditions are
expected to prevail. Winds will remain out of the east northeast.
High pressure to the north will keep an east to northeast flow across
the waters for the next several days with an overnight surge tonight
to near or just into exercise caution range. The flow will lighten a
bit starting Sunday, which will allow the west coast sea breeze to
develop each afternoon.
Relative humidity values will remain above critical levels, so no
fire weather concerns. No significant or widespread fog is expected
for the next several days.

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.
