A "Rare" July cool front will sweep through the state Friday and Saturday. Showers and storms will increase. Some could become strong. As far as what happens behind the front, don't get too excited. The air won't be cool, but it will be slightly less humid. You should really notice this early in the day as lows drop into the 60s. Expect it to arrive Sunday. Dewpoints will lower to the 65-69 degree range. Check out the "Icky" factor post from a few days ago.
Of some interest is a tornado that touched down near Polson, Montana yesterday. Polson is a great town in the mountains of western Montana. It's located on the southside of Flathead Lake which is the largest freshwater lake west of the Mississippi River. I can't even begin to explain how unusual it is to have a tornado up there. I worked in Missoula, Montana for a couple of years back in the late 90s and never saw anything like it. Missoula is located about one hour south of Polson. Anyway, if your interested in more check out the National Weather Service Missoula website or one of the local TV stations... kpax.com or keci.com
