Area Forecast Discussion

1128 PM CST Sun Jan 21 2018

.SHORT TERM...(This evening through Monday)
Issued at 204 PM CST Sun Jan 21 2018

The main story for the next day will be developing low pressure
system across the central Plains. This low will bring heavy snow and
strong winds to north central Nebraska through Monday afternoon.
Snow is already beginning to fall across portions of eastern
Nebraska and the northern Sandhills. Will continue with the Winter
Storm Warning north of a line from Ogallala to Spencer and a
Blizzard Warning south of this line.

The rest of today (Sunday): Precipitation will continue to push into
the region. Currently temperatures are hovering around freezing
which has resulted in some light rain/freezing drizzle/freezing rain
across portions of the I-80 corridor. Further north and east, colder
air has sufficiently moved in and precipitation has changed over to
all snow. As the colder air moves southward, precipitation will
eventually change to snow for the rest of the forecast area.

For tonight (Sunday night): Snow will continue to spread across the
entire forecast area on Sunday night. Northerly winds will increase
to near 30 mph overnight with gusts to 45 mph. The strongest wind
gusts are expected 9pm CST Sunday and 6am CST Monday. During this
time, visibilities are expected to be reduced down to 1/2 mile or
less with some locations down to near 1/4 mile. Strong winds
combined with heavy snowfall rates overnight will result in
treacherous driving conditions. Travelers across north central
Nebraska should expect white out and blizzard conditions on Sunday
night and early Monday morning. In addition, drifting snow up to 2
feet or higher will cause additional travel headaches. Extra caution
should be exercised if travel is necessary on Sunday night through
Monday morning. Winds remain out of the north through 6am CST Monday
morning before slowly shifting to the northwest.

Monday: The low pressure system will slowly push east throughout the
morning. Snow will taper off in a west to east fashion with snow
ending in locations across the west by 8am CST. Snow will eventually
move out of the forecast area in the east by noon CST. Despite snow
ending, northwesterly winds will continue to gust to 30 to 40 mph
through Monday afternoon. Therefore, blowing snow will be a concern
for much of the day. Winds will slowly diminish throughout the
afternoon before finally dropping back to near 15 mph by early
Monday evening, bringing the threat of blowing snow to an end.

.LONG TERM...(Monday night through Sunday)
Issued at 204 PM CST Sun Jan 21 2018

A weak disturbance in northwest flow aloft will bring an increase
in clouds Monday night with no precipitation expected. The northwest
flow aloft will continue through Tuesday, followed by upper
ridging and a thermal ridge developing Wednesday into Thursday.
While MOS guidance has highs into the 50s by Thursday, expected
snow cover of several inches may exist in some areas. Forecast
highs mainly in the upper 30s Wednesday and low to mid 40s
Thursday look more on track.

For Friday into Friday night...An upper trough will traverse the
region, and drive a cold front across on Friday. This will bring a
chance for rain or snow Friday, and a slight chance for snow into
Friday night. Since this will be an open trough, no significant
precipitation is expected. Highs from 35 to 40 on Friday will fall
back into the upper 20s and lower 30s Saturday and Sunday.
