I was en route to Seattle (driving) when the mountain snow was forcasted, so I missed it. But I froze my butt off on the way there - temps were in the low 50's with a cold drizzle in mid-afternoon in Missoula. Cranked the heat up quite a bit in the car.
Then on the way back I overheard the Bozeman forecast on the radio. "Highs in the upper 80's on Saturday with temps in the 60's on Sunday. Expect high temps in the upper 40's on Monday." WTF

NWS is indeed forecasting a high temp of 49 on Labor Day and the leaves are already turning yellow... I feel like I hardly knew ya, summer.
