If true, this is turning into a day like Greensburg.

And it's only about 12:30 pm out there. At least 12 hours to go...

Feed anyone ?

Strong cell just east of Boulder, CO now has tornado warning with it. The warning image box prevents me from clearly seeing any TVS. definitely a strong shear with clearly defined red/to green transition, winds moving away and towards radar.

CBS4.Denver.com reports that a witness in Windsor says there is damage to homes and a cemetary.

Yep there is another tornado on the ground, all still pretty early in the afternoon as well, as someone else said this is going to be a very long day!

#88 Postby **RL3AO** » Thu May 22, 2008 1:32 pm

CNN has video of the tornado. It could be a EF5 if it hit something.

I hear that the metreologist Dr Josh Wurman has his offices up in Boulder. I hope Boulder doesn't get hit as it is only 35 miles from Denver...

Yes - dbz was black - that must be a huge thing.

KWT · #99 Postby **KWT** » Thu May 22, 2008 1:39 pm

Yeah thats sizeable hail, certainly large enough to cause some real damage I'd have thought, yet alone the tornadoes that are about.

Reports put the tornado at 3/4---1 mile wide so yep it was a large tornado, does sound like a high end tornado as well.

Cells starting to develop in eastern Colorado. Double dryline perhaps?
