A strong arctic cold front has brought bitterly cold temperatures,
gusty northwesterly winds and light to briefly moderate intensity
snowfall to portions of central and north central Nebraska this
afternoon. This quick moving system is expected to clear north
central and central Nebraska by mid evening. From now until mid
evening, there will be a threat for blizzard or near blizzard
conditions in these areas. Visibilities as low as a half a mile
with localized areas of a quarter mile or less are possible.
Blowing snow and bitterly cold temperatures are expected overnight

improve by mid evening as snow ends across the area.

In the meantime, travel over north central Nebraska should be
avoided until conditions improve. If you must travel, pack a
winter survival kit in your car. If you become stranded, do not
leave your vehicle.
