Smoke, tropical remnants, weekend events

Tomer’s Take:

  • The tropical remnants from Kay arrive in Colorado Tuesday afternoon (9/13) and continue through 9/15.
  • This precipitation might end as light snow on the 14ers late on 9/14.
  • Smoke goes away on 9/14 as the storm systems sweep the atmosphere.
  • Then a jet streak arrives with wind and lingering rain shower chances north of I-70 between 9/16-9/18.
  • Two big events this week: Pikes Peak Ascent and Marathon, and Run Rabbit Run in Steamboat.
