Area Forecast Discussion...UPDATED
National Weather Service North Platte NE
1133 PM CST Wed Dec 6 2017

.SHORT TERM...(This evening through Thursday)
Issued at 329 PM CST Wed Dec 6 2017

The main concern for the short term will be the continued chances
for snow across portions of northern Nebraska and the Sandhills. A
weak cold front will continue to push southward across Nebraska for
the remainder of Wednesday. Ahead of this front, an intense band of
snow will reduce visibilities and result in a quick accumulation of
snow. Up to an additional half inch is possible in this band, with
some locations seeing up to an inch. The best locations to see
greater accumulations will be across western Cherry and Sheridan
counties where snow will continue a couple hours longer this
evening.

Snow will eventually taper off by mid-evening. Strong upper level
ridging will return to the western US allowing surface high pressure
to build into the region. This will keep conditions dry for the rest
of Wednesday night and into Thursday. A weak short wave will pivot
across southern South Dakota and Northern Nebraska late Thursday
afternoon. As a result of how weak this system is, will keep POPs
under 25 percent. Will hold off on any snow accumulations as well.

Temperatures remain below normal for the next day. Highs only rise
into the low to mid 30s on Thursday with lows tonight dropping into
the upper single digits and low teens (warmest temperatures across
southwest Nebraska).

.LONG TERM...(Thursday night through Wednesday)
Issued at 329 PM CST Wed Dec 6 2017

For Thursday night...A fairly moist atmosphere will be in place
across the area. Some weak lift is indicated in the dendritic
layer, supportive of flurries across northern Nebraska during the
evening, and northeast of a Valentine through Broken Bow line
after midnight. Little or no accumulation is expected.

On Friday, a very amplified upper ridge will be in place along
the West Coast of North America Thursday, as a deep trough extends
from south Texas through the Great Lakes into Eastern Canada.
Some upper height rises do occur this weekend, Otherwise, this
ridge/trough pattern will persist through Tuesday of next week.

Western Nebraska will see highs returning to above normal on
Friday from the upper 30s in the northeast to near 50 in the far
southwest. The upper ridge will advance slightly eastward through
Sunday, with a warming trend expected. Highs will warm into the
mid 40s and lower 50s most areas Saturday and 50s Sunday. Some
cooler air is forecast to drop into the Central Plains Monday and
Tuesday, although the current forecast only lowers highs a few
degrees to the lower 40s to lower 50s. A slight chance for light
rain or light snow as well as sprinkles or flurries across
portions of the north central on Monday, Monday night into Tuesday
morning.

Regarding winds, breezy to windy conditions expected Friday, and increased
winds Friday near CONSMOS guidance. Breezy conditions expected
Monday through Wednesday as northwest flow aloft continues.
