Update
For 12z aviation.

Short term
Today and tonight.

The center of the high pressure has moved east and is now in the
atlantic. This has allowed to winds to shift to more of southerly
flow and has been slowly increasing dewpoints across the area.

Temperatures will be a little bit warmer as many areas will reach
the low 70s. However, portions of the northeast may remain in the
60s. We will see cloud cover in the south through the afternoon as a
backdoor trough to our northeast will help in the lift department,
resulting in the cloud cover. However, with the dry air in place,
moisture will not be abundant enough for any rain. Clouds will be on
the decrease tonight, with lows in the 40s and 50s.

Long term
Wednesday through Tuesday.

Ridging builds in across most of the eastern CONUS Wednesday ahead
of a trough sliding through the rockies. The trough picks up the
remnant energy from hurricane willa and lifts the now shortwave
energy through southern tx and into the northern gulf of mexico by
Wednesday night into Thursday morning. A surface low forms early
Thursday and is expected to push eastward along the gulf coast
Thursday into Friday, increasing rain chances for central al. Models
have come into good agreement on the overall timing of this system,
so i've trended pops upward, closer to the 80-90% range, for the
southern half of our area.

The main longwave trough remains over the eastern CONUS for several
days, and at least two more shortwaves dip into the gulf states
before we get into early next week. The first of these comes
Saturday evening into early Sunday as an upper low digs through the
ohio river valley and into the central appalachians. Expect early
Saturday to be mostly rain-free, but chances increase through the
afternoon and evening as the shortwave axis moves through.

Sunday should remain mostly dry ahead of the 2nd shortwave that
follows a similar track to the previous one. However, moisture
return ahead of this one is more limited, and guidance keeps most of
the energy to our north and west, so I have held off adding
mentionable pops in the forecast for early next week.

Vfr conditions to continue through the period, as high pressure
will slowly exit the area to the northeast. Cirrus from an upper
level disturbance over texas will continue to spread eastward
across alabama through tomorrow. Calm winds overnight once again.

Fire weather
Much cooler and drier weather is expected for the first half of
this week. The next chance for rain builds in on Thursday. There
are no fire weather concerns at this time.

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.
