National Weather Service North Platte NE
921 PM CST Monday Nov 30 2015

issued at 914 PM CST Monday Nov 30 2015

Dry air is shutting down the snow south of Nebraska Highway 2. The
new forecast reduces snow chances in this area and removes Keith
and Perkins counties from the Winter Weather Advisory.


Short term...(this evening through tuesday)
issued at 313 PM CST Monday Nov 30 2015

Upper level low pressure is centered across central Nebraska this
afternoon...and is only very slowly moving east/northeast. The low
should be centered across northeast Nebraska by Tuesday morning.
Light snow will continue through much of the night along and north
of Interstate 80 on the back side of the weak lift will
continues through the night. Have added Sheridan County to the
Winter Weather moist north to northeast flow /trowal/
favors snow in the upslope area of the Pine Ridge in northern
portions of the County. Have also extended the advisory until noon
for western Cherry account for the trowal persisting in
that area through Tuesday morning. Generally expecting an additional
1 to 3 inches of accumulation north of Interstate 80 through north
central and northwest Nebraska...but locally 4 inches or so in
northern Sheridan County.

On Tuesday the weakening trowal shifts east over Boyd and Holt
County as the upper low moves east. Will carry likely probability of precipitation through
the afternoon in these areas where another inch of snow could

Long term...(tuesday night through monday)

As the cyclone makes its way to the upper Mississippi Valley...the
snow in northeast Nebraska will diminish and end by early Tuesday.

Otherwise...for the Middle Range...Tuesday night through Wednesday
night...the statistical output from the NAM and GFS may be a little
too high with temperatures where snow accumulates today and tonight.

Looking into the weekend...another system is expected to develop in
the intermountain region at the end of the week and an upper trough/
low will swing through the central or Southern Plains Saturday night
and Sunday. At this time...there is about 200nm difference in the
track of the system. The European model (ecmwf) and takes the center of the low
through Oklahoma and Kansas with an inverted trough at the surface
extending across western Nebraska while the GFS keeps the inverted
trough over southeast Nebraska. Blending the long range models
actually keeps the precipitation probabilities below 15 percent.
For the time being...then...we will keep the forecast dry.


Aviation...(for the 00z tafs through 00z Tuesday evening)
issued at 531 PM CST Monday Nov 30 2015
