May 29, 2010 wrapup and May 30, 2010

So yesterday we ended up mainly north of Grand Forks, trying to play the warm front/outflow boundary. Storms formed nicely in the region but they were a bit too numerous and outflow-dominant (not enough low-level flow) so we had to take what we were given.

We did see some incredible shelf cloud motions and some small hail--about 1 cm diameter, which was not worth reporting. As well, we experienced an easily severe outflow wind from a storm in Minnesota. Our estimate of the wind speed was well over 50 knots, I thought about 60 so that's what we reported to the NWS. Here are the reports from the day.

All in all, it was a pretty great day.

Today we don't really have high expectations, although we should see storms, maybe pushing the severe limits. Wichita, KS is our initial target. More later.

And speaking briefly on the rain in Winnipeg, all I can say is wow. I hope the flooding is minimal. I'll now present the special weather statement issued by Environment Canada in its entirety.
