And here we are looking at 84º on the thermometer right now here in Houston. I have very good friends that live in Milton, right down the road from Madison, but I think they are in Phoenix with their new grandson right now.

My wife and I have been waiting for her to go into labor at any time for the last week or two, when the weather has been very cooperative for a nice 25-min drive to the hospital. I'm sitting in our home office, looking out the window at this:



We're not getting the brunt of it like they are in western WI / southern MN, but I'm guessing my wife's water will break in a couple of hours.

[Icey455]

thundersnow WITH hail? how strange! Do you think it was "real" hail or just sleet mixed with the snow?

[Icey455]

Well I dont think it was sleet. Can sleet get as big as pennies?? There were some reports on the short term forcasts in the southern WI area warning about possible hail with these thunderstorms.

EDIT: found a few resorces during the event

Well I dont think it was sleet. Can sleet get as big as pennies?? There were some reports on the short term forcasts in the southern WI area warning about possible hail with these thunderstorms. I have no idea where to get these though.

If it was as big as pennies, then I would have to say that you were probably right about it being hail. Sounds like a crazy experience you guys had up there yesterday.

[Icey455]

Indeed, it was crazy out there. The beltline and I-90 were parking lots during the event. luckly I work right down the road, so it was a short trip going about 10 mph watching for the next flash of lighting down the road, at the same time I could barely see 100 feet ahead of me with roaring winds. That's Somthing I will remember for a long long time.
