Starting today in Limon in a very good area for the Denver Cyclone. Storms should initiate by mid afternoon and become Supercells with a great chance of Tornadoes in and around Denver and points east towards the CO/KS Border area later before it all lines out.

Looking similar set-up to yesterday, though 12z NAM points my finger to SE corner of Colorado for most abundant moisture/CAPE and best wind shear overlap:

 

SBCAPE and Td 7pm MDT

0-1km shear and sig. tornado 7pm MDT:

Fairly good upper support at 500mb level:

Precip charts show Limon/Denver/Colorado Springs good bet and also down into SE corner Colorado:

Be interesting to see where, if any, tornadoes drop - NAM points to SE Colorado best bet, but the weather never bears out exactly how the models suggest.

I think for early afternoon I like SE Colorado best too, Nick. And it appears that the team are heading towards a tornado warned cell that is west of La Junta presently

There are a lot of other chasers on this storm. Lost its tornado and severity warning though!

La Junta storm not up to much ATM looking at TVN streams, but keeping an eye on it, as this area looks most favourable for rotating storms.

Just watched some Colorado dust and probably some tumbleweed too blow past one stream as the gust front blew through. Don't think I've ever seen so much tumbleweed as when I've been in CO!

Arkansas River near Las Animas looks very swollen from one of the live streams that just crossed over, all that water headed toward a flooded Oklahoma!
