This Hazardous Weather Outlook is for portions of southwest
Arkansas, southeast Oklahoma and northeast Texas.

.DAY ONE...Tonight...

...A Winter Weather Advisory is in effect until noon Tuesday...
...A Wind Chill Advisory is in effect until noon Tuesday...
...A Lake Wind Advisory is in effect for Southeast Oklahoma until
9 AM CST Tuesday...

Snow is already occurring across Southeast Oklahoma and adjacent
portions of Southwest Arkansas and Northeast Texas Snowfall
accumulations through Tuesday morning will range from 1-2 inches
in most locations with isolated higher amounts possible. Travel
conditions may become hazardous as snow turns to slush and starts
to refreeze on area roadways, especially elevated surfaces such as
bridges and overpasses as well as less traveled secondary roads.

North winds of 15 to 20 mph with gusts up to 25 mph are expected
across McCurtain County during the overnight hours. Therefore, a
Lake Wind Advisory is in effect until 9 AM Tuesday morning.

The north winds combined with the cold Arctic air will lead to
wind chill values falling to between 8 degrees below zero to 2
degrees above zero after midnight through late Tuesday morning.
Therefore, a Wind Chill Advisory is also in effect until noon
Tuesday.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday...

The snow will gradually come to an end during by the mid to late
morning hours on Tuesday, but with air temperatures remaining
below freezing and then plunging into hard freeze conditions
Tuesday night as skies clear, travel concerns will likely continue
through at least late Wednesday and possibly Thursday before
temperatures finally rise above freezing.

Scattered rain showers will return to the region over the weekend
and become more widespread with much warmer air temperatures and
some isolated thunderstorms before ending very late on Sunday as a
cold front sweeps across the region.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, skywarn networks and amateur
radio operators will be needed to report developing icy conditions
this evening, overnight and into Tuesday.

Louisiana and northeast Texas.

.DAY ONE...Tonight...

...A Winter Storm Warning is in effect until 6 PM Tuesday...
...A Wind Chill Advisory is in effect until noon Tuesday...
...A Lake Wind Advisory is in effect for much of East Texas and

A mix of wintry precipitation is already ongoing across portions
of East Texas and portions of Southwest Arkansas and extreme
Northwest Louisiana. A transition to snow is expected in all
locations during the overnight and early morning hours. Total
snowfall accumulations through tonight will range from 1 to 2
inches in most locations tonight with isolated higher amounts
possible. Travel conditions may become hazardous as snow turns to

surfaces such as bridges and overpasses as well as less traveled
secondary roads.

North winds of 15 to 20 mph with gusts up to 25 mph are expected
during the overnight hours across much of Louisiana and East Texas.
Therefore, a Lake Wind Advisory is in effect until 9 AM Tuesday
morning.

The strong winds combined with the cold Arctic air will lead to
wind chill values falling into the single digits after midnight
through late Tuesday morning. Therefore, a Wind Chill Advisory is
also in effect until noon Tuesday.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday...

The snowfall will continue through Tuesday morning and possibly
linger into early afternoon before gradually tapering off in the
afternoon. An additional 2-3 inches of snowfall accumulations
will be possible, but with temperatures remaining below freezing
and then plunging into hard freeze conditions Tuesday night as
skies clear, travel concerns will likely continue through at least
late Wednesday and possibly Thursday before temperatures finally
rise above freezing.

Scattered rain showers will return to the region over the weekend
and become more widespread with much warmer air temperatures and
some isolated thunderstorms before ending very late on Sunday as a
cold front sweeps across the region.
