.SHORT TERM...(This evening through Wednesday)
Issued at 336 PM CST Tue Dec 6 2016

An upper level disturbance will track across the region tonight into
Wednesday. Snow is still expected tonight mainly along and south of
interstate 80 in southwest Nebraska. A cross section indicates a
classic mid level frontal slope, with lift increasing after midnight
and continuing into Wednesday morning. Moisture is quite limited,
but with such cold temperatures some snow will occur as the column
saturates. Thinking right now is less than one inch will fall in
North Platte area along I-80, around an inch or a little more in the
Ogallala area. Around 2 to 3 inches is expected in far southwest
Nebraska near Ogallala. Have shied away from issuing any type of
headline. Winds will remain relativity light, so little blowing snow
is anticipated, and accumulations will be less than 3 inches. As the
upper wave passes Wednesday morning, downglide will quickly take
hold with light snow quickly ending by noon and skies clearing by
late afternoon.

The other story will be the cold temperatures Wednesday. A secondary
cold front will bring a reinforcing shot of cold air to the area,
with highs only around 12 above across far northern Nebraska,
warming to the lower 20s across portions of central and southwest
Nebraska.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 336 PM CST Tue Dec 6 2016

Strong high pressure building in across the northern plains for the
remainder of the week will allow chilly arctic air to filter in to
the area beginning on Wednesday night. The coldest night will be
Wednesday night where air temperatures will drop to negative single
digits across the eastern panhandle and the positive single digits
across central Nebraska. These cold temperatures combined with
northwest winds gusting up to 30 mph on Wednesday night, will result
in wind chills dropping quite significantly during the early
Thursday morning hours. Expect wind chills across the forecast area
to easily drop into the -10 to -20 degree range by 6am Thursday,
with the coldest wind chills across the eastern panhandle. Wind
chill headlines could be possible for Wednesday night. Will wait to
issue anything at this time.

Continuing northwest winds throughout Thursday will keep high
temperatures on the colder side ranging from 15 to 20 degrees.
Temperatures will gradually warm over the next couple days
eventually reaching the upper 30s to low 40s by Saturday. In
addition to warming temperatures, weather conditions remain dry
through the end of the week.

The next system to bring a chance of wintry precipitation will
arrive Friday night and Saturday. Best locations to see snow will be
across northern Nebraska. Snow accumulations are expected to be
minimal at this time, however, some uncertainty still remains in the
track of this storm and any slight adjustments in the track could
significantly impact the snowfall totals.

Dry conditions return on Sunday and last through the beginning of
next week. High temperatures hold steady in the low to upper 30s
both Sunday and Monday.
