Above-normal temperatures continue across the region today.
Strong southerly mixing winds have pushed readings into the low
60s across portions of southeast Nebraska with mid to upper 50s
common across the remainder of the CWA.
This warm southerly flow will continue into the overnight hours
ahead of an approaching progressive upper level shortwave trough.
The associated surface low is currently over the western Dakotas
and will continue to move east across the northern Plains with a
trailing Arctic front driving through our forecast area overnight.
Rain is expected to spread northeast across our southeastern CWA
within the WAA regime while at the same time, precipitation
spreads east across central Nebraska and into our far northwestern
counties directly behind the front. This area of precipitation
will quickly push through the CWA through the overnight hour and .
will likely begin as liquid but quickly change over to snow as
temperatures plummet behind the front. In addition, very strong
northwest winds of 25 to 35 mph with gusts as high as 40 to 55 at
times are expected. The strongest of these winds will be across
our northeastern Nebraska and west-central Iowa counties. Did
hoist a Winter Weather Advisory for northeastern Nebraska and
Monona county Iowa earlier today where greater than an inch of
snowfall is forecast and mentioned the very strong northwest winds
as well. To the south of this, did issue a Wind Advisory for the
remainder of the CWA. After continued southern model trends, did
later decide to hoist a Winter Weather Advisory from near David
City through the Omaha metro. Do think that road impacts are
possible on this southern extent even though we are generally
speaking about under an inch of snowfall. The gusty winds to 45
mph in this area will only exacerbate the road impacts with
reduced visibilities plus it is typically a busy holiday travel-
day. We can't forget about wind chills on Wednesday either with
values likely in the single digits to mid teens by afternoon. The
upper trough axis slides overhead through Wednesday afternoon,
putting a large portion of our CWA into the deformation band
behind the system adding to snow totals, especially in northeast
Nebraska where we have up to 3" currently forecast. Blowing and
drifting could be significant in these area and reducing
visibilities to less than a half-mile at times. We will continue
to monitor if needing an upgrade of a headline.
Snow should taper off from west to east by Wednesday evening as
the system quickly exits the area however winds will still be
gusting to around 15- 25 mph into the evening. This will produce
wind chills to -10 to -15 below in our northeastern CWA to the
single digits above zero in our southwestern CWA.
Christmas Eve day will be quite cold with winds will still around 15-
25 mph producing cold wind chills that hover around the single
digits above and below zero for much of the day as surface high
pressure builds into the region.
Temperatures are forecast to warm quickly on Christmas Day with
strong downsloping winds which should push temperatures into the mid
to upper 40s. Gusty southwesterly winds will still make it feel
chilly. Mostly dry conditions are expected to continue through
the weekend with temperatures near-normal for this time of the
year.
Medium-range ensembles show a large system taking aim for the
nation's mid-section by mid-week next week.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 518 PM CST Tue Dec 22 2020
Deteriorating conditions are expected at all terminals beginning
late tonight. Strong southerly winds shift to the northwest and
increase to 35-45kt and be accompanied by -SN. The combination of
strong and SN will likely push vsbys down into LIFR territory
toward sunrise at KOFK/KOMA and mid morning at KLNK. Expect the
vsby restrictions to be an issue the remainder of the day on
Tuesday. Winds will also remain strong out of the NW 35-45kt.

This front will also bring gusty northwest winds up to 40-55 mph. Winter Weather Advisories are in place across much of northeast and east-central Nebraska and west-central Iowa Wednesday morning into Wednesday evening. Snowfall amounts generally north of a line from David City to Omaha to Harlan, IA could see anywhere from 1-2" of total snowfall with higher amounts around 3 inches possible toward the Nebraska and South Dakota border. There will be significant blowing and drifting of snow which could reduce visibilities to under a half-mile at times. Snow is expected to taper off from west to east Wednesday evening. Gusty winds are expected across the entire region and so a Wind Advisory is in effect across the much of the region throughout the early evening hours Wednesday for gusts up toward 45 mph. Winds will begin to taper off after dark on Wednesday, but may remain around 15-25 mph through the overnight hours and through Thursday. Roads may become slick and visibilities will likely be reduced in areas of snow and blowing snow. High profile vehicles may have difficulty with travel, especially on east and west routes, including Interstate 80. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday The probability of widespread hazardous weather is low. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed.
