.SHORT TERM...
Tonight and Tuesday.

Weak surface ridging is present today across much of Alabama on the
dry side for the most part of what is left of Bonnie with the
exception of the southern part of the state and into the Florida
panhandle in associated with a surface boundary. We do have decent
cumulus development evident on visible satellite thanks to ample
heating and some tiny showers here and there on the radar. Any
showers that pop up should be short lived and not strong. Will not
carry any mentioned rain chances for tonight as these are heat
induced storms. Expecting any lingering activity to die off near
sunset with the loss of heating. For Tuesday, looking for the
ridging to have an even better hold on the pattern as the low
pressure associated with Bonnie deteriorates further. Only a 10%
very low chance of shower activity is expected. Temperatures will be
similar to today.

.LONG TERM...
Tuesday night through Sunday.

Mainly isolated storms expected during the afternoon hours
through the work week with temperatures above normal through
Wednesday. The upper ridge will slowly weaken beginning Wednesday
as a short wave trough moves into the Plains states and pushes an
upper trough axis towards the Lower Mississippi Valley region.
However, rain chances will generally not increase due to weak flow
and lift to the south of the trough axis.

As we progress towards Friday, the upper trough axis will become
nearly stationary near the Alabama and Tennessee state line due to
a cut-off low over Texas. This pattern will not bring significant
rainfall to central Alabama, but there will be chances of rain
every day and increasing some as we reach Saturday and Sunday as
the upper low begins to open up and gradually shift eastward as a
second upper wave pushes through the Ohio Valley region. The
increase in moisture at the end of the week and into the weekend
will also limit daytime temperatures to values closer to average.

.AVIATION...
18Z TAF Discussion.

Not much change from yesterday, except a little warmer. Some
isolated showers are possible this afternoon, but chances are low
for any one spot and difficult at best to pinpoint. Northwest to
north surface winds will continue for this afternoon as we are
being wedged between the deteriorating low of Bonnie to the east
and weak ridging to the west-northwest. Overnight low level
moisture for any dense fog is low but a couple of brief 4-5SM obs
are not out of the question.

.FIRE WEATHER...

Look for only low to minimal rain chances through the middle of
the week with above normal temperatures. Rain chances will
increase after Wednesday as upper level toughing pushes slowly
southward into Alabama. There are no fire weather concerns at
this time.
