Denver has had 1" hail yesterday and today, at 6pm-8pm. Right now, severe-warned hailstorms from Denver to Longmont. Yesterday I got a pic of some of the mammatus clouds at 8:30, and a video of some lightning. Storms developed in a NE-SW line near Denver yesterday, and one storm tracked straight northward to Fort Collins and Cheyenne. I only got a trace of rain, or a bit more. When the storm was gone, and the sun had set, I watched the Loveland city fireworks to the SSE. And even then, I saw distant lightning behind the fireworks. Radar showed the rain was close to Denver.
Edit:
more thunder and rain within about 1 mile of downtown Loveland
Edit:
Tonight, the storm expanded northwards, much like last night. My place got 0.10" to 0.15" I think, with small hail. I narrowly avoided large hail again. Hail reports in Loveland and Fort Collins.
