FORECAST SUMMARY: Monday June 15th, 2026, through Thursday June 18th, 2026
Ozone:
Ozone concentrations are expected to be in the Good (Green AQI) to potentially low-Moderate (Yellow AQI) range.
PM-2.5:
PM-2.5 concentrations are expected to be in the Good (Green AQI) to low-Moderate (Yellow AQI) range.
FORECAST DISCUSSION:
Mid-June is here, which is hard to believe, but summer is in full swing after very warm temperatures last week and just below-to-near normal temperatures for the week ahead. We start off the week today, Monday, with clear skies and surface temperatures expected to hang around the 70s. Monday will be the last predominantly dry day this week until Friday with multiple rounds of rain expected to impact the Great Lakes this week. A Low-pressure system and associated rain showers move across the state on Tuesday which will see rain during the Tuesday evening timeframe. This system will also shift our winds to the north-northwest which will cool us down for the majority of the day. Wednesday will also see another system moving across the state which, potentially, may see more rain compared to Tuesday. Timing for rain on Wednesday is somewhat similar to Tuesday with showers, and potential thunderstorms, nearing the late afternoon and evening. These systems move out of the area on Thursday and Friday with Thursday seeing leftover, residual showers and Friday being mostly clear. Although not a complete washout of a week, numerous rain chances will help keep the gardens watered.
For air quality, PM2.5 continues to remain in low concentrations although upper-level smoke has been present in some quantities. Our eyes are staying peeled, though, for near-surface smoke as we move more into the summer months. Ozone looks to be mostly Good this week due to the numerous rain chances to help keep the atmosphere clean, along with the shifting winds and high temperatures remaining in the mid-70s at most. There may be some increases in the Moderate range on an hourly basis, especially on Monday and Friday, which will have clear skies, but nothing more than low-mid Moderate concentrations should be expected this week.
EXTENDED FORECAST:
The clearing trend on Friday continues into the weekend with sunny skies on Saturday and for the most part on Sunday. Air quality will remain in the Good range.
