The episode as NWS GID wrote it up.
Thanks to a somewhat-unexpectedly potent combination of intense northwest winds and relatively-minimal snow, mainly the daytime hours on this Wednesday featured several hours of near-blizzard to outright-blizzard conditions across most of South Central Nebraska, shutting down several highways for a time and snarling pre-Christmas travel. Various law enforcement agencies reported dozens of traffic accidents and slide-offs (fortunately none fatal within the local area) and the following main highways were reported closed at various times: Interstate 80 between York and Kearney, Highway 281 between Grand Island and Hastings, Highway 30 from Grand Island-Kearney, Highway 34 from Grand Island-York, Highway 6 from Hastings-Kenesaw and Highway 81 near Shelby (all had re-opened by late afternoon). In Adams County, snowplows were pulled off the road for several hours due to very poor visibility. As for areal coverage of white-out conditions, the worst/longest-lasting issues focused within counties both along/north of Highway 6 and also along/east of Highway 183 (including the Tri Cities). Within this area, most places endured at least semi-frequent blizzard conditions for 6-8 hours while accumulating 1-3 of snow, while far northern counties (such as Valley/Greeley) saw blizzard conditions for as long as 10-12 hours and received slightly-higher snow amounts up to 3-4. Meanwhile, the situation was not as severe within far southern/southwest counties especially near the Kansas border, where snow was lighter/less-intense compared to farther north (amounts mainly under 1) and didn't last as long. Although the magnitude of wintry precipitation/blizzard impacts varied somewhat across South Central Nebraska, all 24 counties dealt with at least 9-12 hours of feisty northwest winds, commonly sustained 30-40 MPH and gusting 45-60+ MPH. A few of the highest official peak gusts at airports included: 76 MPH at Ord and 61 MPH at Grand Island, Hastings and York. While there were no known reports of substantial wind damage, NWS observers near both Arcadia and Shelby noted that several small tree branches were downed.
Getting into more detail regarding event timing and meteorological background, the main driving force in the mid-upper levels was the passage of a deep, slightly-positively-tilted trough, with its primary vorticity maximum tracking from the Central Rockies on the evening of the 22nd, and then across the heart of Nebraska-Kansas during the day on the 23rd before departing into the Upper Midwest/Upper Great Lakes through the evening-overnight. At the surface, the associated low pressure center gradually intensified from around 994 millibars as it crossed Nebraska during the overnight-early morning of the 22nd-23rd, to 988 millibars by mid-day in the IA-MN-WI border area, and then maintained intensity while reaching Lake Superior overnight. Locally, the initial surge of strong northwest winds crossed South Central Nebraska during the pre-dawn of the 23rd behind the main synoptic cold front, but gusts largely held under 50 MPH. The overall-strongest winds ended up occurring between mid-morning and mid-afternoon, corresponding to the peak surface pressure gradient between the departing/deepening low and strong high pressure nosing in from the west-northwest (for a few hours the west-to-east gradient across the state of Nebraska averaged near 25 millibars!) As for snowfall timing, an initial, narrow band swept across most of the area during the pre-dawn hours, but the primary, broad zone of mainly light-to-moderate snow (with brief heavier bursts) gradually overspread South Central Nebraska from west-northwest to east-southeast during the morning, eventually departing in similar fashion during the afternoon. Actual falling/accumulating snow ended across most of the area between 2-4 p.m., but lingering blowing snow and ground blizzard conditions held on for a few more hours...until gusts diminished more consistently to around 30 MPH-or-less after nightfall. From a forecast review perspective, the intense winds and at least minor blowing snow impacts were fairly well-anticipated, as a High Wind Warning was issued for the entire area 12-18 hours in advance and a Winter Weather Advisory (for the majority of the area) was issued 6-18 hours out. However, especially the southward extent of accumulating snow and the resultant potential for all-out blizzard conditions was not as well foreseen (especially as far south as the Interstate 80/Highway 6 corridors), with several counties not placed under official Blizzard Warnings until rather late in the game. For sure, one of the biggest takeaways/reminders from this event was that even minimal snowfall can wreak havoc on travel in the presence of powerful winds.

AREA FORECAST DISCUSSION
National Weather Service Hastings NE
1150 PM CST Tue Dec 22 2020
.DISCUSSION...(This evening through Tuesday)
Issued at 440 PM CST Tue Dec 22 2020
Highlights/main points of the entire 7-day forecast:
- By FAR the main focus/time on this forecast shift was spent on
the very first 24-30 hours, which will feature a blast of strong
northwest winds area-wide (high confidence) and for especially
Nebraska portions of our coverage area (CWA) a good chance of at
least light snow accumulations, with areas north of I-80
currently favored for amounts as high as 1-2" (medium-
confidence). As a result, a combination of a High Wind Warning
(CWA-wide starting either at midnight/6AM) and a Winter Weather
Advisory for Nebraska counties north of Interstate 80 (starting
at midnight) was issued this afternoon.
- More on this below, but easily the biggest
uncertainty/dilemma/point of concern at this time is whether we
are hitting the snow potential hard enough for late tonight into
Wednesday daytime. While both snow chances (PoPs) and amounts
themselves were raised modestly from previous forecast
(especially north of I-80), a few recent models (including 12Z
ECMWF/18Z NAM) suggest our snow amounts might need to be raised
a bit more. Stay tuned for at least minor (perhaps somewhat
noticeable?) tweaks to snow amounts from the upcoming evening-
overnight shifts.
- With so much focus on the first 24-30 hours of the forecast,
will gladly state that the vast majority of the remainder of the
7-day forecast (Wednesday evening through next Monday) currently
carries fairly high confidence in remaining dry and fairly quiet
weather-wise. Following our brief blast of noticeably-colder
temperatures Wednesday (highs only in the 20s to low 30s and
perhaps falling further during the day), a gradual moderation
will start to get underway on Thursday (Christmas) with highs
20s northeast to around 40 southwest, then followed by the
overall-warmest days of the next week on Friday-Saturday with
widespread highs in the 40s-low 50s. This warm-up is short-lived
however as colder air returns for Sunday-Tuesday with highs
currently only aimed 30s to low 40s Sunday, then only low-mid
30s at best Monday-Tuesday.
- Although it is way at the end of the official 7-day forecast
(and mostly beyond), fans of longer-term forecasts will note the
POSSIBILITY of a potentially-significant winter storm that is
showing very early/preliminary signs of affecting our general
Central Plains region during the Tues-Thurs time frame next
week. Although this will obviously bear watching in the coming
days, anybody reading this knows darn well that it is FAR too
soon to put much stock in the details of this system. For now,
our forecast merely reflects "innocent" low chances for snow
starting next Tuesday.
Taking a quick look/recap of the current/recent weather scene as
of 4 PM: No big surprises to speak of at all, as indeed today has
panned out to be the anticipated warmest day of the week, as
mostly sunny skies (although filtered this afternoon by passing
high cirrus) combined with steady south winds (generally sustained
15-20+ MPH/gusts 25-35 MPH boosted afternoon high temps well into
the mid 50s to low 60s range across most of the CWA (and even some
spotty mid 60s mainly far southwest). In the mid-upper levels,
water vapor satellite and short term model data clearly reveal a
potent shortwave trough tracking directly toward our region from
the west-northwest, with the main vort max in the base of the
trough currently digging across southern WY. At the surface, the
gusty south winds today are focused out ahead of a north-south
oriented lee trough to our west, which currently registers around
995 millibars in the NE Panhandle.
With the main points of the 7-day forecast as a whole outlined
above, will now conclude with some details SOLELY FOCUSED on these
next 24-30 hours, and starting with some further background on
Warning/Advisory headlines:
- High Wind Warning:
In short, simply upgraded the inherited High Wind Watch for the
western CWA to a Warning (starting midnight) and then also
included the rest of the central/eastern CWA in a High Wind
Warning as well (starting 6 AM). Admittedly, confidence is not
overly-high that we will truly see widespread Warning criteria
(sustained speeds commonly 40+ MPH/gusts 58+ MPH), but with good
potential for several hours of sustained 30-40 MPH and at least
sporadic gusts to 50-55 MPH likely, felt that it was prudent to
"bridge the gap" between Warnings to our west and Advisories to
our east with a CWA-wide Warning. For sure, the initial surge of
strong northwest winds will arrive overnight from west-to-east,
and while this first surge could at least flirt with Warning-
criteria gusts (especially west) as stout pressure rises move in,
the overall-strongest winds of the event are expected to occur
during the day Wednesday before slowly-but-surely easing below
headline-criteria late Wednesday afternoon into the night.
- Winter Weather Advisory:
As touched on above, the snow situation (particularly exact
amounts) carries considerably-lower confidence than the wind
situation. Even at this close time range, models vary considerably
regarding how aggressively they phase low-mid level
lift/saturation, and thus snow potential. For sure, our official
forecast of generally 1-2" north of I-80, a dusting up to 1" along
the I-80/Hwy 6 corridors and only a dusting at best near/south of
the state line is a "middle ground" between the more
aggressive/benign model extremes. That being said, confidence that
at least SOME snow will fall between late tonight and early
Wednesday evening is increasing, and PoPs have been increased
(quite possibly not enough). Obviously with such strong winds, it
won't take much snow at all to reduce visibility to less than one
mile, and at least briefly/localized much lower, with yes even
near-blizzard conditions possible at times, but with expected
fairly brief duration due to this system being fairly progressive.
In the end, coordinated with neighboring LBF/OAX to get the ball
rolling with an official Advisory for those areas north of I-80
where confidence is highest in at least 1" of snow falling (not
that it will be easy to measure in the wind), but obviously at
least minor travel impacts could occur south of the current
Advisory as well (including I-80 corridor. In addition, there
COULD be a flash-freeze scenario late tonight into Wed AM
depending on how quickly temperatures fall and allow the initial
rain and/or rain-snow mix to freeze onto roads.
Other short term weather details...
This evening-tonight:
Both the upper level trough and strong/associated surface cold
front will enter/surge across our area late tonight, with the main
vort max directly over/very near our CWA at sunrise Wednesday. All
precip chances kick in post-midnight as precip type will likely
initially start out as rain showers briefly before fairly quickly
transitioning to snow/snow showers. Low temps are a little tricky
as the strong winds will initially keep things rather "mixed"
before the strong cold air advection arrives. Actual overnight
lows were nudged up slightly, ranging from low 20s northwest to
low 30s far south-southeast.
Wednesday daytime:
The fairly quick-moving/progressive upper trough passes directly
overhead, keeping areas of wind-whipped snow/snow showers going
throughout much of the day (especially in our northern CWA).
However, by sunset any falling snow should be gone/departed east
of our area. High temps are a bit misleading as they will likely
occur right away in the morning with steady-to-falling temps
possible thereafter. For sure, most areas can expect actual temps
in the 20s most of the day with wind chills only single digits-
teens.
Wednesday evening-night:
In the wake of the departing system, skies will largely clear and
winds will gradually decrease, although it will remain modestly-
breezy throughout the night with sustained speeds commonly 10-20
MPH and some higher gusts. Though these breezes will help keep
temps from falling to their full potential, still have most areas
bottoming out well down into the teens.

.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Thursday)
Issued at 1150 PM CST Tue Dec 22 2020
A strong cold front is approaching the forecast area with strong
northwest winds. Upstream as the front passed gusts are 40kts or
higher. Expect this to impact both terminals. Also high-resolution
runs have indicated that precip will begin as rain and quickly
switch to snow this morning with more snow than originally
anticipated. This heavier snow and wind will cause reduced
visibilities. MVFR to IFR conditions are expected with some
potential for LIFR if snow is heavy enough. Snow will persist
throughout the day today with the winds to at a minimum off and on
IFR to LIFR conditions depending on the intensity of the snowfall
throughout the day. Winds and snow will eventually decrease
around 21-00z today.

Overnight, strong northwest winds will surge across the entire outlook area behind a powerful cold front. A High Wind Warning is in effect after midnight for all counties west of the Highway 281 corridor, where the overall-strongest overnight winds should focus. Please refer to the Warning statement for more details. In addition to strong winds, portions of the Nebraska outlook area could pick up light snow accumulation between midnight and sunrise. Although snow amounts through sunrise will likely be less than 1 inch, a Winter Weather Advisory is in effect after midnight for counties north of the Interstate 80 corridor. Please refer to the Advisory statement for more details. .DAYS TWO THROUGH SEVEN...Wednesday through Monday. During the day Wednesday, the entire outlook area will have very strong northwest winds, and especially Nebraska portions of the area will continue to see areas of at least light accumulating snow. As a result, a High Wind Warning is in effect through 6 PM for the entire outlook area, and a Winter Weather Advisory is in effect through 6 PM for Nebraska counties north of Interstate 80, which is the area that stands the best chance of seeing total snow accumulation of at least 1 inch. Please refer to the High Wind Warning and Winter Weather Advisory statements for more details. Please note that even south of the official Winter Weather Advisory area, at least minor travel issues due to the combination of falling snow and strong winds could also affect Nebraska counties along the Interstate 80 and Highway 6 corridors. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed through tonight, but any reports of accumulating snow over 1 inch or possible wind damage would be appreciated from late tonight into the day Wednesday. && More information may be obtained at the following web page: https://www.weather.gov/hastings Pfannkuch
