Area Forecast Discussion
National Weather Service North Platte NE
328 AM CST Sat Dec 10 2016

.SHORT TERM...(Today and tonight)
Issued at 327 AM CST Sat Dec 10 2016

Light snow will continue over the north central zones through the
morning. Visibilities have been reduced to a mile at times so more
than flurries. Less than a half inch additional accumulations
expected from Valentine to Oneill. Snow will end through the
morning. Today a trough of low pressure lies along the front range.
Surface low pressure organizes through the afternoon and evening as
a mid level wave moves in from the west. Warm air advection will
develop and spread warmer temperatures into western Nebraska with
some temperatures approaching 40 over the southeast Nebraska
Panhandle and southwest Nebraska. The low moves into western Kansas
through the evening with cold air at the surface undercutting the
warmer air aloft. Looks to be an east west boundary set up through
the Sandhills through the evening with southerly upslope flow over
it. Timing of cooler air will make or break the forecast. Have opted
for areas of light snow in the vicinity of and north of the east
west frontal boundary. lows will drop off rather quickly with teens
north and low 20s south.

.LONG TERM...(Sunday through Friday)
Issued at 327 AM CST Sat Dec 10 2016

Dry weather returns on Sunday as high pressure builds back into the
region. Temperatures begin to slowly rise as well starting on
Sunday. High temperatures reach the low to mid 30s on Sunday and the
mid 30s to low 40s on Monday. High pressure remains across the
region through mid-week.

A quick moving disturbance arrives on Tuesday night bringing a quick
half inch to 1.5 inches to mainly western Nebraska. Greatest totals
will be further west. A series of weak waves coming off the Rocky
Mountains will continue through Wednesday night keeping snow chances
around through this time frame. An additional half inch additional
snow accumulations are possible through Wednesday.

This shortwave will be quickly followed by a stronger developing low
pressure system on Thursday night and through Friday night. While
this system is still several days out and model intensity is still
uncertain, this system does look like it could blanket much of
central Nebraska with a couple inches of snow. Will continue to
monitor this system in the upcoming days. Temperatures remain in the
upper teens to low 20s from Tuesday through Friday.


.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1116 PM CST Fri Dec 9 2016

IFR will spread east through nrn Nebraska in snow and low cigs
affecting areas along highway 20. Local LIFR may develop. These
conditions should affect ncntl Nebraska Saturday morning. MVFR
cigs are expected to linger throughout the day Saturday across
Ncntl Neb with improvement to VFR across Wrn Neb.

VFR is generally expected south of Nebraska highway 2. The latest
short term models are generating isolated to scattered snow shower
activity along I-80 tonight. This could result in a brief period
of MVFR/IFR cigs and vsby in snow.
