Aviation [through 12z Monday]
Diurnal convection will develop later this morning and afternoon,
favoring tlh westward into the fl panhandle and eventually into se
al before dissipating around mid evening. Vcts continues at
tlh ecp dhn in the tafs later today. Aby vld will be far enough
east from the higher moisture to keep mention out of tafs at this
time.VFR outside of convection with light east to southeast
winds.

Prev discussion [256 am edt]
Near term [through today]
Moisture is on the increase as an upper low moves westward across
the northern gulf to our south and a mid level high moves further
offshore the east coast. Pwat on the 00z tae sounding showed 1.78
inches and is progged around 2 inches today and a little higher
across the fl panhandle. Area cross sections show good moisture up
to 500mb as opposed to more drier air and subsidence of the past few
days. An area of higher moisture on the east side of the upper low
will advect into the area which will lead to higher rain chances
from tlh westward with the highest chances (50-60%) the the fl
panhandle counties. Chances decrease north and east of tallahassee
with most spots in ga remaining dry. As more cloud cover is
expected, highs will be in the low 90s.

Short term [tonight through Tuesday]
In the upper levels a ridge will be over the southeast. A trough
will be over the central u.S. At the surface a weak pressure
gradient will be over the southeast with high pressure over new
england and a low near the great lakes and canada. A cold stationary
boundary will extend through the tennessee valley and lower
mississippi valley. Low level flow will be southeasterly. Pops will
be 30 to 70 percent tomorrow as deep layer moisture increases and a
dissipating cold front nears the region. On Tuesday pops will be 20
to 50 percent as deep layer southerly flow continues. Lows will be
in the lower 70s. Highs will range from upper 80s to lower 90s
with lower temps co-located with cloud cover and rain.

Long term [Tuesday night through Sunday]
In the upper levels a ridge will be over florida. A broad trough
will remain to the north but will dip down into the tennessee
valley. At the surface a weak pressure gradient will be over the
southeast. A slow moving cold front will approach the region late
this week. It will likely dissipate over or just north of the
region. The best chance for showers and thunderstorms will be
Wednesday and Thursday with pops of 40 to 60 percent. Otherwise pops
will be mainly in the 30 to 40 percent range. Highs will range from
upper 80s to lower 90s with lower temps co-located with cloud cover
and rain. Lows will be in the lower 70s.

Marine
Light to moderate southeasterly winds will become light and southerly
midweek. Seas will be 2 feet or less.

Fire weather
Hazardous fire weather conditions are not expected over the next
several days.

Hydrology
Most local rivers are steady or falling. Most local rivers remain
well below action stage. Rainfall totals from 0.25 inch to 1.75
inches expected over the next week. The lower totals are expected
over SW georgia and higher totals closer to the coast.

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.
