FORECAST SUMMARY:
Monday, June 10th, 2019 through Monday, June 17th, 2019
Ozone: 8-Hour average Ozone concentrations will be mostly Good through the forecast period.
PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good with some Low Moderate through the forecast period.
FORECAST DISCUSSION
Rain will move out of the area, Monday morning, as a front migrates across the state. Brisk northwest winds will push dry air into the region during the afternoon and skies should be generally clear by sunset. Air Quality issues will be small as the incoming air will be clean.
Clear skies should persist through Tuesday as high pressure rapidly pushes through the upper Midwest. Highs should reach the mid-70’s with comfortable humidity borne on light westerly winds. Air Quality should remain Good.
The Wednesday/Thursday time frame shows another chance of rain, albeit not as much as we saw during Sunday and early Monday. I expect shower activity to start Wednesday afternoon and linger into Thursday morning. Cooler temperatures on Thursday will struggle to reach the low 60’s with Good Air Quality.
Surface high pressure will nudge its way into the lower Great Lakes region during Friday providing a pleasant day with westerly winds and continued Good Air Quality.
More unsettled weather will likely return to the region during the weekend. The models are not totally certain on the nature of the precipitation potential but overcast skies and mostly southeast winds in advance of another low pressure system should keep ozone levels low and fine particulates in the Good to Low Moderate range.
EXTENDED FORECAST:
Air Quality is expected to remain mostly Good going into the next work week.
