321 pm edt Sat mar 25 2017
Short term (tonight - Sunday)
Afternoon visible satellite imagery is showing a broken cumulus
field covering the florida peninsula under broad easterly winds, as
the surface ridge axis remains north of the area. Despite the overall
dry airmass, southeasterly mean low level flow across southwest
florida will support slightly higher moisture over the southern
extent of the forecast area, and a few isolated showers cannot be
completely ruled out later this afternoon and into the early evening.
Otherwise, generally rain free conditions will continue through
Sunday morning. By Sunday afternoon, an upper level trough and
surface cold front will approach the area, with moisture increasing
ahead of the system. This will allow for a few showers to be possible
mainly over the nature coast where moisture will be highest, and it
will not be impossible for a few stray showers to develop farther
south along the sea breeze.
Temperatures will remain near to slightly warmer than normal, with
lows tonight in the low to mid 60s, and highs on Sunday in the upper
70s and low 80s.
Mid term/long term (Sunday night-Saturday)
Weakening mid/upper level shortwave will move east of the region
Sunday night with another weakening shortwave moving across the
lower mississippi and tennessee valleys Monday and Monday night
before out into the atlantic ocean on Tuesday. These systems will be
well to our north and have little impact on our weather early in the
period with the warm and dry weather continuing. During midweek some
mid/upper level ridging will build over the region as the next
cutoff low moves out of the desert southwest into the
central/southern plains Thursday and gradually weakens as it moves
across the eastern u.S. Late in the week. Models are depicting
differences in location and strength of this system with the gfs
further south and stronger and therefore bringing a better chance of
showers than the ecmwf/canadian late Thursday night into Friday
night. For now have continued the slight chance to chance pops
during this timeframe, but if the weaker and further north pattern
verifies we would not see much more than some clouds with this|
system. Temperatures during mid to late week will continue above
GenerallyVFR conditions will continue through the next 24 hours.
The exceptions will be that there is a small chance of a few showers
this afternoon around kfmy/krsw/kpgd, then brief periods of MVFR
ceilings overnight cannot be completely ruled out, mainly over the
interior. Generally easterly to southeasterly winds could be
interrupted this afternoon by a sea breeze for sites near the coast.
High pressure centered over the atlantic will continue to ridge into
the eastern gulf through the weekend, as a weak front washes out
over the northeastern gulf on Sunday. The surface ridge will then
shift west towards florida through mid week, with light winds and
Relative humidity is expected to remain above critical thresholds
through the rest of the weekend and into next week, with no
significant fire weather concerns anticipated. A few patches of fog
will be possible during the next couple of nights, but widespread fog
is not expected.

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.
