Here’s how it shapes up:
Tonight Heavy Snow Tuesday Snow Tuesday Night Heavy Snow Wednesday Heavy Snow Wednesday Night Heavy Snow
The National Weather Service defines heavy snow as:
- snowfall accumulating to 4″ or more in depth in 12 hours or less; or
- snowfall accumulating to 6″ or more in depth in 24 hours or less
That’s a lot of snow for that many days. I don’t know how they will define Thursday and Friday. Maybe Monster Snow. Here is the GFS model from the Navy’s NOGAPS site. They use reds and yellows to show heavy amounts. Isn’t it pretty?
That is the 12 hours ending Friday morning about 5am. The 12 hours before and after are just as pretty. If it comes as snow, we are looking at 2 feet in less than 24 hours.
I hope you are ready. Here is a great mesage from the Coconino County: Prepare for Extended Snow
Please, let me (email@example.com) and the National Weather Service hear your snow reports.
The National Weather Service in Flagstaff needs your snow reports. Here is a pdf that tells you how to report:
