Area Forecast Discussion
National Weather Service Birmingham AL
201 PM CDT THU AUG 18 2016

.DISCUSSION...

An uptick in coverage this afternoon as the upper ridge continues
to weaken over the area and some weak upper lift traverses across
the tennessee valley. Most of this is diurnally aided, however
lingering showers/storms have maintained themselves through the
past couple of evenings, so some isolated storms could very well
continue deep into the evening hours tonight.

Above average rain chances for Friday through Sunday as ample
moisture will work with a digging trough and frontal boundary.
Looks like most locations will see some rainfall through this
period. Drier air behind the boundary will push into the state and
limit any showers to the far southern counties on Monday with dry
conditions taking hold of the area thereafter. Pleasant
temperatures and humidity behind the front considering it is still
August.

.AVIATION...
18Z TAF Discussion.

Afternoon satellite and radar shows developing storms primarily over
the north eastern portion of the CWA, near KBHM, KEET, KASN, and
KANB.  This afternoon and early evening day time heating will
instigate scattered thunderstorms for all sites however VFR
conditions will prevail.  Winds will remain light throughout the TAF
period and likely become more variable in the overnight hours.  A
chance of rain returns tomorrow morning, primarily for northern
sites.

.FIRE WEATHER...

A hot and humid airmass will remain in place through the rest of
the week and into the weekend, with scattered afternoon and
evening showers and storms each day. Less humid air will make its
way into the state early next week. Critical fire weather
conditions are not expected.
