Overview

  • A stationary high-pressure ridge anchored by Tropical Storm Dexter keeps skies dry and seasonably mild with highs in the low to mid-80s through midweek.
  • Smoke from Canadian wildfires has pushed particulate matter into levels deemed unhealthy for sensitive groups across multiple Northeast Ohio counties.
  • The Air Quality Alert remains in effect overnight Monday into Tuesday, advising those with lung conditions, children and older adults to limit strenuous outdoor activity.
  • Cloud cover increased Monday and a stray afternoon shower cannot be ruled out Tuesday, but overall rain odds stay minimal until late-week.
  • A cold front and an upper-level system moving in from the Upper Midwest are forecast to raise rain and thunderstorm chances by this weekend.
