.DISCUSSION...

Isolated showers across across central Alabama this afternoon should
dissipate by early evening due subsidence under strong upper ridge.
Upper air soundings indicate a pocket of drier mid level air
across southern Georgia and northwest Florida. Satellite/radar
imagery show minimal cloud cover across this region, and this
dry pocket should expand westward across south Alabama tonight
and Friday. Deeper moisture will pool across north Alabama on
Friday as the center of the upper high shifts eastward. The
lowering of 500mb heights and pooling of moisture should result in
higher coverage of convective activity across north Alabama on
Friday than today.

Beyond Friday the overall upper air pattern does not change much
across Alabama with a large scale ridge over the Gulf Coast
region. This ridge will make it difficult for any tropical system
to make a poleward movement. The models are not showing any
consensus with the tropical wave currently moving through the
Bahamas. The forecast for central Alabama will not show any
impacts from this tropical system due to uncertainty. Overall the
forecast will show little day to day variability with daytime
temperatures running above normal and low rain chances.

58/rose

.AVIATION...
18Z TAF Discussion.

Mainly VFR conditions will prevail through the TAF period. A few
isolated showers and storms will be possible near the northern TAF
sites this afternoon, but coverage is too low to mention anything
besides VCSH. Will have to monitor dewpoint trends at TCL for
possible fog development overnight, but confidence is too low to
mention in the TAF at this time.

32/Davis

.FIRE WEATHER...

A prolonged period of generally dry conditions will continue thru the
weekend, with only low rain chances at times. Temps will remain
slightly above normal thru Sunday. Critical fire weather
conditions are not expected.
