I'd say the chance of precipitation is 100% and didn't stop from last night. It did lighten up for a little while this morning around 9:00 but it never really did stop for the whole day. It looked like was going to break away around 6:30 this morning, but no such luck. Sucked BIGTIME for our yard sale, not many people like venturing out in the cold and rain.

I know, that's always a show stopper. haha

I can't believe I went up in shorts and a t-shirt. Froze my butt off. haha

So, people! That want to move to Wyoming, it's August 15 and we got snow, blowing now, nasty weather. Weather service even issued a warning. Sure you want to move here?

[ElkHunter]

There are currently no alerts pending. So I thought I'd throw this in.

1983 - Record warmest September temperature at Billings and Sheridan (103 degrees), and Miles City (106 degrees); for Billings, this was the 8th consecutive day with a high above 90 degrees

Don't often get much wind out here at the cabin. But got a couple friends coming out to go fishing. Wouldn't you know it, wind is at 43mph sustained, gusting to 45. Hopefully it'll die down before fishing time.

This week, I'm going to change the thread to Winter storm warnings. It's that time of year.
