Welcome to April!
Unbelievably, all of the computer models have changed overnight. Flagstaff will receive 5-7 feet of snow overnight! The National Weather Service is clearly scrambling to get a grip what they should do about this. No severe weather warnings have been issued. Expect temperatures to drop severely this afternoon and early evening. Snow should start to fall right at sunset. Be ready to not be able to travel for several days.
What a way to start April!
