Nearly 2 hours now with off and on rolls of thunder in southeast Aurora! WOW - incredible. The snowfall rates are 2 to 3 inches per hour. It is really piling up - already covering the sidewalks, driveway and the streets.
Thundersnow always comes with intense snowfall rates - in some cases it can be 5 inches per hour! I just saw a report near Evergreen in the foothills of 5.5 inches of snow in 90 minutes.
Look at the line of storms east of Denver!
