.SHORT TERM...
Today and Tonight.

A cool front has stalled out near the the I-20 corridor early this
morning. Surface dewpoints were still in the middle to upper 60s
across most of central Alabama. The surface front will begin to
push southward later today as the next upstream short wave digs
southward out of the Ohio Valley States. The low levels of the
atmosphere still remain relatively dry, which will hinder
convective potential again today. Scattered showers and
thunderstorms will develop this afternoon ahead of the slow moving
surface front. Areal coverage will be limited and kept rain
chances generally 30 percent or less for areas south of I-20. A
few storms will linger into the early evening hours, but expect
the convection to dissipate by 9 pm. Cooler and drier will work
into north Alabama this evening with temperatures falling into the
50s across areas along and north of I-20 by Wednesday morning.

.AVIATION...
18Z TAF Discussion.

VFR conditions are expected (in an overall sense) through the TAF
period:

As we progress through the afternoon, peak heating and presence of a
surface front should give rise to scattered showers/t`storms.
Such activity is most probable toward MGM-TOI where VCTS is carried,
with some spotty showers possible near ASN-ANB where VCSH is
mentioned. This activity will move southeasterly and dissipate
during the early-evening hours. Otherwise, expect a mix of cumulus
and cirrus. Surface winds are progged around 5-7 knots.
Passage of the front and drier air moving in should preclude or at
least more-so limit any return of sub-VFR conditions heading into
Wednesday morning (perhaps something can get going near MGM-TOI).
We`ll take a look at this again in forthcoming updates.

.FIRE WEATHER...

A front with relatively higher rain chances will move slowly
through Central Alabama through Tuesday. Drier weather returns
for Wednesday and beyond. No fire weather concerns are
anticipated.
