FORECAST SUMMARY: Saturday July 22nd, 2023, through Sunday July 23rd, 2023
PM-2.5: PM-2.5 concentrations are expected to be in the Good to Moderate range.
OZONE: Ozone concentrations are expected to be in the mid-to-high Moderate range.
FORECAST DISCUSSION:
This Saturday morning provides winds staying more southerly throughout today and tomorrow, Sunday. This will keep our surface temperatures in the upper-70s to low-80s throughout the state, through the weekend and into next week. An upper-level disturbance makes its way through the lower peninsula overnight which may trigger some short-lived rain during the Sunday morning hours. As the afternoon approaches, the rain should be moving off to the southeast and bringing the clouds with it as the sun is expected to come back out mid-afternoon.
As stated in yesterday’s forecast update, Ozone will be continued to be looked at but as of now, it does not look like widespread Ozone will be an issue for western lakeshore counites. The wind direction predominantly staying southerly, cloudy morning and early afternoon conditions, along with potential rain shower will help keep Ozone production low. If by chance Ozone does develop, it will mainly stay out over the lake and may only impact hourly concentrations. Overall 8-hour averages for Ozone are expected to be in the mid-to-high Moderate range for Sunday and Monday, as of now. Ozone for Monday will be looked at tomorrow morning. PM-2.5 looks to remain in the Good to moderate range throughout the state.
EXTENDED FORECAST:
Next week sees quite the warmup with surface temperatures well into the 90s with southerly winds. Overall air quality will be looked at throughout the week.
