Nice cumulus cloud blewup NE of Fort Collins. It was going to move in to an area of decent CAPE and helicity of no more than 200 m2s-2.
Bulk shear may have been around 40 kts so I figured something good might come of it.
Cell went up, area of slight rotation observed, then began to die as another cell from a line extending southeast towards limon blew up to the SE of my position.
Each cell showed a short lived funnel.

A great quick chase!

It brought me to this article written by Jon Davies posted on Stormtrack a while back... http://www.stormtrack.org/library/forecast/ehi.htm
Definitely a good read~

Add QUEBEC to the list ;)

F1 tornado touchdown North of Montreal, Quebec, Canada chased by Allan Theunissen.

The same supercell cycled and produced another tornado a couple of miles east of the first touchdown (lasted 15 mins)
