Update
For 18z aviation.

Short term
Today and tonight.

Overall, expect a pleasant albeit warm day for the area today. We
will continue to be on the drier side of maria with easterly to
northeasterly flow leading to synoptic scale subsidence across
central al. Expect clear to mostly clear skies with highs in the mid
to upper 80s, which is slightly above normal for this time of year.

Low level high pressure begins to spread across the central plains
behind a cold front this afternoon. Moisture availability looks to
be limited ahead of the frontal boundary, so expect the amount of
rain to decrease as the front pushes into the ms river valley by
tonight.

Long term
Wednesday through Monday.

The forecast for Wednesday remains on track. The main upper low
associated with the rockies system moves ene out of manitoba
toward quebec. At the same time, a piece of energy breaks off from
the upper trough over the rockies forming a closed low over the
desert southwest. Ridging fills in over the gulf behind a
weakening maria (as she moves northward along the atlantic
seaboard over the atlantic) and starts to wrap its way around into
texas and the lower ms river valley. We should remain dry for
Wednesday across central alabama being on the dry N NE flow side
of maria along with ridging in place across much of the deep south
except for SE ga N fl where some weak upper troughing extends
from maria.

At the surface, a cold front makes progress across the central
part of the us expected to move through late Wednesday into early
Thursday. Overall thinking is that any moisture will be shallow at
best, so we are not expecting any precipitation as we are not
getting return flow and available moisture in place ahead of time.

The second reinforcing surface front moves in behind it on Friday
into Saturday. Extended guidance continues to indicate a 1028 to
1030 mb ridge center behind the front. The center digs down out of
central canada and into the great lakes by Saturday with some ne
flow into alabama. From there, the ridge looks to elongate and
expand further to stretch from maine to texas with a center over
new england and a more easterly flow over the deep south by Sunday
as what is left of maria pushes far away over the N atlantic.

The forecast looks dry with the arrival and after the passage of
the two surface fronts. The only exception could be across the
southeast counties of alabama. The upper troughing out of maria
mid week over ga fl looks to retrograde back to the SW a little
over the NE gulf. However, models do not indicate any surface
features. Some isolated showers storms will be possible on
Saturday as a result. For the most part we are looking at a fairly
nice weekend on into the beginning of next week with generally
drier and cooler conditions which will be more seasonal for late
september into early october.

Fire weather
Look for a warm and rain free forecast for today across central
alabama. Relative humidity values only drop into the upper 40s and
50s. There are no fire weather concerns at this time. A change in
the pattern is expected by early Thursday with the arrival of a
front along with cooler and drier weather expected as we head into
the weekend.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
