.DISCUSSION...
Issued at 238 PM CST Thu Feb 11 2021

Today:

Light snow has spread across northeast nebraska ahead of a weak
shortwave that will swing through this afternoon.  Light snow will
linger into the afternoon with measurable snowfall remaining
north of I-80. Models suggest that most only see minor
accumulations today at 1 inch or less. Areas closer to the South
Dakota border may see a smidge over an inch, while areas closer to
I-80 will be closer to Trace to 0.5 inches. Snow this evening
will taper off after sunset, and we will see a short dry period.
As far as temperatures go today, we are looking at highs this
afternoon in the single digits across the area. Wind chills today
will remain in the -5 to -10 range. Overnight, expect lows to
drop to 0 to 10 below.

Friday:

The bitter cold continues Friday morning with 6am wind chills at
20 to 25 below zero. Unfortunately, highs on Friday will only top
out a few degrees above 0. Besides the cold, another shot of snow
will move in early Friday morning as another short wave swings
through. Snow will spread across the entire CWA by mid-day. While
forcing isn't particularly strong, long duration, ample moisture,
and a fairly deep dendritic growth zone will allow for slightly
higher accumulations with this one. Snow ratios could also be
approaching 20 to 1 in some spots. With the timing of this system,
expect to have impacts on the Friday evening commute. Snowfall
will linger into the overnight hours on Friday, eventually coming
to an end after midnight. Snow totals will be heavies across the
central and southern parts of our CWA where 2-4 will be possible.
In the far northeast, lower amounts of 1-2 will be possible.

With the expected snowfall in mind, have issued a Winter Weather
Advisory for the central part of the CWA where snow totals are
highest. This includes all of I-80. With the timing of the event,
slippery roads will be possible for the evening commute. Use
caution if traveling. Additionally, have issued a wind chill
advisory for the entire area for wind chill of 20 to 25 below.

The Weekend:

Over the weekend temps will take a dive. By Sunday, expect highs
below 0 across the entire area. Additionally another round of
light snowfall will be possible Saturday night into Sunday morning
across portions of southeast NE and southwest IA where another 1-3
inches will be possible. Additional wind chill products will
likely be needed over the weekend. Especially Sunday morning
where some locations may approach -30 to -35.

Monday and Tuesday:

Monday is going the be the coldest day we have
seen and quite some time. Wind Chills Monday morning will be
dangerous for anyone outside. Windchill will be in the -30 to -35
range across the entire area. If you have to spend any time
outdoors, cover all exposed skin, as frostbite could occur in a
matter of minutes. High temperatures Monday afternoon, will not
make it above 0 in most locations. In fact, the warmest wind chill
we will see on Monday will still be in the -10 to -15 range. While
Tuesday's high temperature may be slightly warmer, the wind chill
will not. Expect another morning of dangerous wind chills with -25
to -35 expected again.

Rest of the week:

But there is some light at the end of this. After our bitter cold
Monday, we will start to see a VERY slow warming trend. While
dangerous wind chills are still expected through the work week, we
may finally see a high near 20 by the end of the week. Long range
models have started to hint at the potential for seeing above
freezing temperatures by the end of the month. For now, lets just
take it a day at a time, and dream of warmer weather.
