This Hazardous Weather Outlook is for the counties served by the
National Weather Service office in Birmingham.

.DAY ONE...Outlook Through Tonight.

Dense fog will affect east central Alabama overnight. Visibilities
will drop below one half of a mile, with several areas near zero at
times. This area is generally east of a line from Gadsden to Troy.
Southerly winds will increase overnight and improvement should take
place after 4 am.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

There remains a slight chance for a wintry mix of precipitation on
Friday, initially across our far northwest counties of Marion,
Winston along with portions of Lamar, Fayette and Walker Counties as
freezing temperatures are expected to be achieved before
precipitation ends across the area. A slight chance of light wintry
precipitation will also exist across our north-central and northeast
counties Friday afternoon and evening as temperatures drop to below
freezing before precipitation fully moves out of the area.

There remains low confidence in this forecast due to the expected
light intensity and limited duration of frozen precipitation along
with the potential that all of the precipitation moves out of the
area before temperatures fall below freezing.

A cold airmass will reside across the region through the holiday
weekend. Temperatures on Sunday morning could briefly fall to near
15 degrees in the normally colder locations, typically sheltered
lower-elevation spots across our far northern counties. Confidence
remains low for this potential as most locations are expected to
remain above hard freeze criteria at this time.

Even colder air is expected to arrive on Tuesday with the potential
for the normally colder locations across our northwest counties to
briefly fall to near 15 degrees. The confidence remains low for this
potential at this time as the majority of locations are expected to
remain above hard freeze criteria.

Reaching hard freeze criteria appears a bit more likely on Wednesday
morning across our northern counties with potential lows at or below
15 degrees possible roughly along and north of Interstate 22 west of
Birmingham and roughly north of Interstate 20 east of Birmingham.

The combination of light winds with these very cold temperatures
could produce wind chill values in the single digits across our
northern and central counties Tuesday night through Wednesday


Activation of storm spotters and emergency management may be needed
