I know this is late, but last week a whole slew of tornadoes were loose in Northern Colorado.
This one was about 1 mile wide. I knew of at least 7 different tornadoes that touched down that day. I have never seen anything like this so far West in this state. Several people I know had significant damage to their homes (roofs torn off, etc.) One person I know had her child in a daycare there, where all of the kids were shuffled into a vault at a bank. It was quite scary!
