Can’t believe it!! We are never gonna shake this snow I swear. Didn’t hear any thunder today myself. Some huge rain drops (thought I might see some hail) in Beikser. Was out in Drumheller today (escaping the city life in Calgary) and nothing but showers. The thunderstorms are down south enjoying the warmer weather I guess. Nice blog!!
May 7th, 2008 at 8:17 pmstarting to snow now here in red deer. big flakes that are melting on contact now. ive seen enough snow already! prairiechaser: were you on any storms last summer? i was on a couple supercells, one near alsike, ab that dropped a funnel 3/4 of the way to the ground. awesome storm. 20 more days im outta here PB!
May 8th, 2008 at 8:11 amWow looking at the Hinton and Jasper cameras, looks like a foot. Cochrane looks like they have at least a few inches. Here in Airdrie rain has been off and on. 5mm of rain last nite, but no snow yet as its still +2. There really was a thunderstorm yesterday here, and Pat I got a couple pics of the pea size hail, although it was almost melted a half hour later when I found my digital. Just looked at Lethbridge AMA camera, nice there with a big chinook arch and that wonderful west wind.
Cheers

May 8th, 2008 at 11:43 amNo thunder here either, so close though.
We have a skiff of snow on the ground here and it’s still snowing lightly.
That NE wind can bugger off any time!
No I missed out on the thunderstorm season last year. This year will be my first go out here. I chased in Ontario from 2000 - 2005. Was living in the mountains with no transportation but now that I do I’ll be out in the prairies!!! Can’t wait!!
