Short term (through Friday night)
A fairly active late afternoon and early evening in store as a back
door front... Just north of the fl ga state line... Drops slowly south
across the remainder of the region. The front... In addition to
seabreeze collision and outflows... Will help generate scattered storms
first between the i-95 corridor and u.S hwy 301 and then mainly
between u.S. Highway 301 and i-75 of NE fl during the remainder of
the late afternoon into the early eve before slowly fading out.

Drier air aloft advecting into the area could help produce storms
with strong and gusty winds in addition to frequent lightning and
locally heavy rain.

A deep layer ridge will build into the tenn valley on Thursday and
carolinas on Friday. A mid upper (tutt) low will move across
south fl on Friday. The surface ridge will extend from the
northeast portions of new england south into the area providing a
deepening onshore flow to the area. Slightly drier air also advects
in from the north which will help limit pops across most of SE ga
and extreme NE fl on Thursday although pops will continue especially
near the i-75 corridor of NE fl near stalled out frontal boundary.

Pops will be limited to near the coast on Friday as strengthening
onshore flow may bring in coastal showers isolated storms.

Long term (Saturday-Wednesday)
As the ridge continues to push off to the east of new england, an
area of low pressure will be passing across the southern tip of
the florida peninsula towards the gulf of mexico. The prevailing
flow will shift to out of the southeast over the course of the
weekend and into the beginning of next week. Moist air will be
drawn into the region and, coupled with weak low level shortwaves,
a good amount of shower and thunderstorm development is likely
during this span, with the most abundant amount of convective
activity expected on Monday and Tuesday, with storms developing
along the coastline and pressing inland. High temperatures during
the weekend are anticipated to be in the low 90s and upper 80s for
the inland areas and even as low as the mid 80s along the
coastline. At the beginning of next week high temperatures are
expected to rise slightly for inland areas, putting non-coastal
areas solidly into the low 90s. Overnight low temperatures will
follow suit, with the weekend inland lows dropping into the low
70s and high 60s, but will then warm up to being in the low to mid
70s at the beginning of next week.

Aviation Weakening backdoor front and sea breeze activity
expected to produce some scattered showers and storms at NE fl
taf sites this afternoon and have kept vcts at jax crg vqq sgj,
with slightly better chances at gnv and have added a tempo group
for possible MVFR vsbys CIGS and gusty winds in storm activity.

Left any shower activity out of ssi TAF as expected to develop
south of the terminal there. After 23-01z time frame (sunset)
expectVFR conds to dominate with some convective clouds slowly
dissipating by midnight. Towards 12z Wed sunrise expect some
patchy MVFR fog possible at inland TAF sites of vqq gnv but
chances still too low to include at this time.

Marine A backdoor front will move south across the coastal
waters before washing out tonight. High pressure will build
north of the waters producing an onshore flow for the remainder
of the week into early next week.

Rip currents: moderate risk.

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 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 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.
