First Blizzard Warning Since January 31, 2011

Good Sunday,

Wow! Well, the storm has trended far enough south to bring blizzard conditions to the I-70 corridor. Let’s put this in perspective. It has been 1755 days since our last 3″ snowstorm and our last Blizzard Warning was January 31, 2011. The snowiest November ever was 9.1″ in 1923 that came in one storm. We are at 1.8″,so far, this November.

Here is the time line. The snow will begin in KC from west to east between 10 AM and noon. Roads will become wet then slick. A blizzard will be ongoing northwest of KC by 11 AM. The main part of the blizzard for KC will be noon to 6 PM with snowfall rates 1″-2″ per hour and wind gusts 35-45 mph from the north. The snow ends rapidly from west to east 6-9 PM with blowing snow ending around midnight.
