The Mid-Ohio Regional Planning Commission has extended the Air Quality Alert through Thursday for Delaware, Franklin, Fairfield and Licking counties, mostly as a result of the transport of wildfire smoke across eastern Canada, coupled with ground-level ozone concentrations.
High pressure will build south, with a very dry northerly flow carrying dense smoke from Canadian wildfires. Afternoon temperatures topped out in the mid-70s, with hazy sunshine.
Under mainly clear skies tonight, temperatures will plummet in the mid-40s, unseasonably low levels for early June, which reflects very low humidity.
Partly cloudy skies and pleasant temperatures in the seasonable mid- to upper 70s are expected for the remainder of the week, warming to the low 80s on Saturday.
A storm system will bring a stronger front that usual on Sunday, triggering widespread showers and a few rumbles of thunder. Showers will likely linger into early Monday, with pleasant weather returning next week.
