331 am edt Mon may 29 2017
Short term (today-Tuesday)
A strong u l ridge will be centered over the florida
peninsula today and will shift east of florida on Tuesday,
but will still hold over the region. A cut-off low over the
northern great lakes will rotate slowly north toward
southern hudson bay on Tuesday. Southern extent of
associated l W trough will sink south and will approach
northern florida late Tuesday.
At the surface, florida peninsula will be on the western
periphery of a large area of high pressure centered over the
central atlantic. The ridge axis, which has been south of
the forecast area creating onshore boundary layer flow, will
lift gradually north across the central florida peninsula
on Tuesday. Boundary layer flow will shift to the
east southeast with increasing deep layer moisture.
Hot conditions expected across west central and southwest
florida today under mostly sunny skies as the u l ridge will
be anchored over the region creating strong large scale
subsidence over the region. Strong subsidence will persist
on Tuesday, however slightly deeper moisture and sea breeze
boundary collision over the interior peninsula will create a
chance of afternoon thunderstorms. Continued hot conditions
across the forecast area, however daytime temperatures will
be a degree or two lower on Tuesday than Monday due to
slight increase in cloud cover.
Long term (Tuesday night-Sunday)
On Tuesday high pressure on the surface and aloft is
centered over the atlantic with the surface ridge extending
eastward over the florida peninsula as moisture us pulled
northward under southerly flow and as a weak cold front
approaches the florida panhandle. By Tuesday evening
interior showers occur primarily over the interior. By
Wednesday afternoon more moisture has returned and scattered
thunderstorms form over the peninsula and are primarily|
over the interior. With the surface ridge extending east-
west across the state and weak high pressure aloft his
pattern of afternoon thunderstorms will continue into Sunday
with seasonal temperatures.
Vfr conditions will prevail for the next 24 hours under
mostly clear skies.
Winds will remain less than 15 knots with seas less than 4
feet through the period. Main hazard will be an increasing
chance of late afternoon evening thunderstorms mid to late
week. The stronger storms will be capable of producing
strong gusty winds, locally rough seas, and frequent cloud
to water lightning.
No fire weather hazards are expected this afternoon.
Minimum relative humidity values will drop near 35 percent
for a few hours over the interior peninsula this afternoon,
however winds and durations are expected to remain below

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.
