MISSOULA — We've seen above-average highs across Western Montana since pretty much August 18th.
A couple of places previously hit the century mark earlier in the summer (St. Regis & Trout Creek at 101°, Plains and Alberton at 100°), but a few just hit 100° for the first time on the 25th — Libby, Troy, I'm looking at you!

It's not a guarantee we'll hit 100° each summer — there have been several where we didn't; much like this year in Missoula (98°) and Kalispell (95°).
But typically, Missoula will see its last 100-degree day around July 28th — the latest 100° reading was August 24, 1969.
Kalispell's last 100° day averages around July 27. The latest 100° reading was also on August 24, 1969.
