August 8, 2006 Storm Chase

With this storm there were 3 main complexes (if I'm using the word correctly) that formed today... one north by cheyenne and fort collins, one south by pueblo, and one east by Limon. We decided to chase after the one to the east. It was a decent severe TS but no tornado warnings issued for it. Looks like they did issue some on the south storm based on radar but no confirmed tornadoes.

We headed east on I 70 to hwy 36 (where 70 jogs south) and kept going east on 36 basically to kansas. We ended up punching through the north side of the storm and experienced HEAVY rains, flooding, extensive lightening <1/2 mile, and some small (gravel size) hail. I noted that even small hail decreases visibility dramatically due to the fog it generates on the ground.

After punching through we saw some pretty cool looking cloud formations including some shelf cloud activity and swirling scud. We managed to stay ahead of the storm though it was coming almost due east toward us. I wanted to get south of it but roads are scarce out there and it continued to advance fairly rapidly.

As the storm got close we could see a lot of cloud motion but not much formed in terms of structured rotation. However, we DID see a couple of dust devils on the ground. They were fairly far away though and could have been gust front. I tried to get some photos and video but not sure they came out.

This was the first chase I took advantage of my cellular data service and was able to look at (near-)real-time radar and other info. While coverage was sparse at times, we usually weren't any more than 20 minutes without an update. I saved off some of the radar images of the storm while we were in the vicinity. Three separate cells colliding created some pretty interesting returns.
