FORECAST SUMMARY: Friday November 3, 2023, through Monday November 6th, 2023

Ozone: Ozone season is now over and will start forecasting again in the spring 2024.

PM-2.5:  PM-2.5 concentrations are expected to be in the Good to low-Moderate range.

FORECAST DISCUSSION:

Michigan ends the week on a higher note than when started with surface temperatures climbing into the upper 40s and low-mid 50s. Southerly flow has been building since yesterday, Thursday, bringing in warmer air and clearer skies. Today, Friday will see relatively sunny skies and winds blowing from the SSW. Overnight tonight, a weak system traverses the state with a cold front associated with it, so there may be a chance of a popup rain shower. Due to the weak cold front, tomorrow, Saturday may see slightly cooler temperatures, but the majority of Michigan will see temperatures in the upper 40s to low 50s. Sunday continues the trend of surface temperatures in the upper 40s but may see more sunshine than what is expected on Saturday. Sunday night into Monday presents us with another Low-pressure system which will influence our weather throughout the day on Monday as we start Monday warm and dry, and end cooler and wet.

For air quality, the Ozone season is now over so we will stop updating the Ozone forecast in our updates until the 2024 season starts in the spring. PM-2.5 will continue to see Moderate increases during the morning hours when winds are light. The past few days have seen rather strong winds gusts throughout the day to dissipate PM-2.5 concentrations, so this will be expected the next few days as well.

EXTENDED FORECAST:

As stated above, an early week system is expected to impact our state Monday into Tuesday. This will help keep overall air quality Good.
