FORECAST SUMMARY: Monday May 15th, 2023, through Monday May 22nd, 2023
OZONE: Ozone concentrations will range from Good to Moderate throughout the forecast period.
PM-2.5: PM-2.5 concentrations are expected to range from Good to low-Moderate throughout the forecast period.
FORECAST DISCUSSION:
The beautiful Spring weather from the weekend continues into this week with ample sunshine and surface temperatures in the upper-60s and 70s throughout the Great Lakes State. This is attributed to regional High-pressure clearing the way for clear skies and temperatures near seasonal norms. Along with sunny skies and warm temperatures, winds should be relatively light from the WNW. This weather pattern sticks around through Wednesday until a Low-pressure system drifts into the area from the north on Thursday. This will shift winds to more southerly flow and cloudier conditions for the end of the week. Precipitation does not look to start until early Friday morning and will be on and off throughout the day on Friday.
The rain may hang around to start off the weekend with temperatures in the 60s and possibly 70s as we approach Sunday. Winds will shift back for the weekend and into next week due to a High-pressure system setting up just to our west.
For air quality, with most of the week being under northerly flow, the airmass will be relatively clean with little pollutants. When winds shift to more southerly flow later this week, concentrations may uptick but the rain on Friday will help clean out any buildup. Concentrations should remain low with winds shifting back to northerly for the weekend. Cooler temperatures will help keep Ozone production at bay although we will have ample sunlight to start off the week. There might be some Moderate concentrations on Tuesday, but only should hang around the mid-Moderate range. Light winds in the mornings may allow for PM-2.5 concentrations to increase but afternoon increase in winds will help blow those concentrations out of the area.
EXTENDED FORECAST:
Monday will continue what Sunday provides for us with winds shifting to more southerly to start off next week. Overall air quality should remain Good.
