We know the cold is coming but did you know that snow may fall in Las Vegas New Years Eve or Day? There’s good model agreement that snow will reach the LV Valley floor in the coming days and may even see Vegas end December with more snow than New York City.
A record 3.5″ of snow fell in Oklahoma City yesterday (6″ for the season) which is more than Chicago and Boston’s paltry 2.9″. (info via Ralph Fato)

Latest ECMWF surface shows the cold upper low above Vegas with low thicknesses that would support snow to low levels.

Yesterday morning’s low fell to 34 degrees at Las Vegas’s McCarran Intl Airport but it’s expected to dip into the 20s in coming nights which would be the first below freezing temp there since December last year!
Meanwhile in Alaska, temps remain abnormally mild with Fairbanks only receiving their first low below -20F yesterday. That’s the 3rd latest.
In Anchorage, they’ve spent an entire year above zero.
