... Winter Weather Advisory remains in effect until midnight CST
tonight...

A Winter Weather Advisory remains in effect for snow and blowing
snow until midnight CST tonight for all of the panhandles except the
southeast Texas Panhandle.

* Timing: periods of light to occasionally moderate snow will
continue before slowly tapering off late tonight.

* Main impact: snowfall accumulations of 1 to 4 inches combined with
north winds of 20 to 30 mph with higher gusts will likely cause
areas of blowing snow by this evening. Visibilities will also be
reduced to near one quarter of a mile at times. As a result... travel
will likely become hazardous across the area by tonight.

* Other impacts: the strong north winds will cause wind chills
to fall to around zero Thursday morning. In addition... areas
of blowing snow may continue into Thursday even after the snow
ends.

Precautionary/preparedness actions...

A Winter Weather Advisory means that periods of snow... sleet... or
freezing rain will cause travel difficulties. Be prepared for
slippery roads and limited visibilities... and use caution while
driving.

... Winter weather impact statement...

Valid...

Today through Thursday

Winter weather expected...

Snow and blowing snow

Affected area...

The Texas and Oklahoma panhandles. With the greatest impacts across
the Oklahoma Panhandle and the far northwest and north central Texas
Panhandle where the heaviest snow will combine with the strongest
winds.

Forecast timing of the event...

Snow will be common through the day across the western and
central Oklahoma Panhandle and the northwest Texas Panhandle.
Some light snow and light rain is expected across the rest of the
area. The snow is expected to pick up in intensity across these areas
late this afternoon into this evening. Snow will slowly come to an
end from northwest to southeast overnight into Thursday morning. A
strong north wind will blow the snow around starting tonight and
lasting through Thursday.

Potential impacts...

Snow accumulations of 2 to 4 inches are expected across the
Oklahoma Panhandle and much of the Texas Panhandle with about one
inch in the southeast 4 counties of the Texas Panhandle. The
heaviest snowfall is still expected across the Oklahoma
Panhandle and the northwest Texas Panhandle. A strong north
wind will develop tonight and will last through Thursday. The
strong north wind will cause blowing and drifting of the
snow... especially where the greatest accumulations occur.
Roads will become snowpacked and icy... especially across the
northwest half of the area. Wind chills will get down into the
single digits Thursday morning.

Discussion...

The winter storm now has two parts to it. The first part is
expected to track across northern New Mexico and then into western
Kansas by tonight. This first piece of energy will bring the
accumulating snows to the northwest half of the area today into
early this evening. The other piece of the storm will be the main
upper level low that will develop into a major winter storm for the
Central Plains states. This upper low is expected to track across
southern New Mexico and across the South Plains of Texas and into the
Red River. A shield of snow is expected to develop on the north side
of the low center by this evening... putting the southern and eastern
Texas Panhandle on the northern fringe of the snow. There is much
uncertainty with the track up this main upper level low. If it tracks
further to the south... then the snow amounts will be much less for
the southern and eastern Texas Panhandle and if the low tracks a
little further north... then the southern and eastern Texas Panhandle
may see accumulations of snow greater than 2 inches.
