Well here in Denver, we have went from a record high of 74 degrees on Saturday to 27 degrees with blowing snow less than 24 hours later.
The snow would be considered light to moderate if it weren't for the winds. They are sustained in the 30s and gusting to near 50 mph at times.
It is slowing travel a little but not stopping it. I think it is worse on the roads than in the air.
My house is in the southern approach path to Denver International Airport, and those planes have been coming over constantly all morning.
For those not familiar with Colorado weather, this is pretty typical stuff for us for this time of year. 40 to 50 degree temperature swings in 24 hours are just a way of life.
Weather here is very dramatic, largely made possible by the Rocky Mountains and Denver's relation to that wall of rock. It is any meteorologist's dream.
The same storm system impacting us today will move across the nation over the next few days, bringing a large area of wintry precipitation from Oklahoma and the Ozarks all the way up to the Great Lakes.
Ahead of the front, strong to severe thunderstorms will form later today and rumble into early next week.
The lower Mississippi River Valley will could see a few doozies by late Monday, with a few tornadoes not out of the question.
