tonight and Saturday.

Showers and storms should continue propagating eastward with the
greatest coverage transitioning to our east-central counties this
evening. Areas that have already experienced rainfall are unlikely
to see additional development, and coverage will decrease tonight
as the boundary layer cools. This activity is generally being
supported by weak height falls associated with an approaching weak
upper-level trough and east-west oriented cold front. The front
should continue to move slowly southward and become nearly
stationary across north alabama. This setup will provide a good
focus for numerous showers and storms across our forecast area on
Saturday.

Saturday through Thursday.

A wet and rainy weekend looks to be in order across the forecast
area as the trough continues moving across the far eastern conus
with a ridge and drier airmass building in upstream over the great
lakes region. The east to west oriented surface front will meander
across the tennessee valley and inch its way into northern alabama
on Saturday. This will support numerous to likely showers and
thunderstorms among a moist airmass with highs in the upper 80s to
near 90f across the forecast area both days. Best rain coverage
will be during the afternoon but with some rain lingering after
dark as well. Two separate developments, combined with southerly
flow around the bermuda high, will help usher this boundary back
to the northeast before it has a chance to make it south of the
forecast area. The first being a low off the eastern coast of
florida, which bears watching over the next few days for tropical
development, although this feature will stay well east of the
forecast area thanks to southwesterly steering winds aloft
associated with the second and more influential feature. A
shortwave trough embedded within a larger trough will deepen over
the central and midwest CONUS extending south into the gulf of
mexico Sunday into Monday as southwesterly winds become more
prevalent over the forecast area. As the shortwave moves across
the southeast, rain chances are progged to remain elevated heading
into early next week with highs lowering into the upper 80s for
most of central alabama on Monday and potentially Tuesday as well.

We could see a touch of dry mid-level air move in behind the trough
in our western counties on Tuesday which may limit overall rain
chances west of i-65, but would expect high moisture content to
remain below 500mb for continued support of 50 to 60 percent pops.

A cold front is expected to pass on Wednesday and Thursday as the
large-scale trough and low height center continues to rotate
slowly eastward over ontario and hudson bay. Should see a north to
south surge of drier air behind the front towards the end of this
extended forecast with rain chances finally trending downwards
due to the drier low and mid-level airmass. Increased sunshine and
lower rain chances will allow highs to rise back into the low
90s, although humidity values will be much lower.

Aviation
00z TAF discussion.

Central alabama remains south of a quasi-stationary front through
the period. The atmosphere is typical of summer time with high
precipitable water values and high surface dew points. Convection
has covered a good part of central alabama today, but the activity
has migrated with outflow boundaries to near mgm. This activity
will last a few more hours and have some mention of convection at
mgm toi this evening. Much of the other areas have been worked
over and did not see an immediate threat elsewhere. Since there
was a fairly large coverage of rain today , some places heavy,
have added a mention of some light fog near daybreak at most
terminals. A few of the model soundings indicate some potential
for ifr ceilings too, but we hold off mentioning anything that low
just yet due to overall confidence and light overall flow.

The front slowly inches southward on Saturday but much of central
alabama will remain in virtually the same airmass. Expect more
showers and thunderstorms especially by afternoon. Some areas
could see activity before then. Have a combination of prob30 and
vcts for all terminals. Outside convection, winds will be light
and variable.

Fire weather
High rain chances and rh values will continue through the weekend
for most of the forecast area. There are no fire weather concerns.

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.
