Short term
Through tonight.

Isolated showers and storms have developed this afternoon, mainly
across the northern half of the area. This activity will drift
southward, and diminish with sunset. Mostly clear skies are
expected overnight, with light fog as low level moisture remains
high. Overnight lows will be in the low to mid 70s.


Long term
Monday through Saturday.

An elongated deep layer ridge will remain in place on Monday
across the deep south eastward to the atlantic. Models continue to
trend slower in bringing mid-level moisture back into central
alabama in the east-southeast flow south of the ridge axis, due to
a stronger ridge and further southwest track of the tutt low
moving into the northwestern gulf. Have slight chance pops for diurnal
convection along the i-85 corridor, with scattered coverage
limited to our far southeastern counties. Across the northern half
of central alabama, a very isolated shower storm can't be ruled
out given the lack of a strong cap, but coverage should be 10% or
less as updrafts will entrain very dry air aloft. Few to scattered
cumulus are expected across the area, with more cumulus in
southeast alabama though even there some breaks are likely.

Cirrus is expected to be very limited due to the further southwest
track of the tutt low, and will be dependent on any convective
debris. So conditions still look favorable for eclipse viewing.

Another warm day with highs in the low to mid 90s expected, with
perhaps some slight relief from decreased insolation during the
eclipse. Convection should dissipate after sunset.

The ridge begins to weaken during the day on Tuesday as a trough
digs into the great lakes. Deep layer moisture will increase with
pwats increasing to around 2 inches in our southern and western
counties. Expect scattered diurnal convection across much of the
area, a bit more isolated in the far northeast. Some models try to
indicate a weak MCV drifting westward over georgia which will have
to be monitored for any enhancement in coverage over our southeast
counties. Meanwhile a cold front will be pushing southward through
the ohio valley ozarks. Will keep some small rain chances going
overnight across the far north in case any remnants of pre-frontal
activity makes it there.

The cold front will move into central alabama Wednesday Wednesday
night, enhancing rain chances over the area. A developing lee
trough along the east coast may also enhance pre-frontal
development but also limit convergence along the front. There are
some lingering questions about whether any weak upper-level
forcing will be present and how quickly mid-levels dry out. So did
bump up rain chances a bit but some additional adjustments will
probably be needed. Lapse rates shear look weak so severe storms
are not expected.

Thursday and Friday will see a northwest-southeast gradient in
rain chances, with lower to nil chances further north due to dry
post-frontal air and higher chances southeast closer to the front.

The pattern will de-amplify into a west-northwest flow pattern by
Saturday, while weak wedging develops along the east coast.

Placement of increased moisture along the leading edge of
developing easterly low-level flow will determine rain chances on

00z TAF discussion.

We have a few small storms remaining on radar thanks to the aide
of some outflow boundaries. Still a chance thru 1z of a brief ts
at tcl. Included a tempo for northerly winds at eet from the
outflow but this is weakening and do not think that we will get
a TS to develop as it passes. Otherwise, we have a similar night
to last night with some MVFR visibilities possible late at a few
of the usual low near creek spots. Low rain chances exist for
Monday afternoon in the south but not confident enough to mention
in tafs at this time.


Fire weather
Moisture and chances rain increase gradually through the week,
ahead of a cold front that will move through the area Wednesday.

There are no fire weather concerns at this time.

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.
