FORECAST SUMMARY: Monday, December 6th, 2021, through Friday, December 10th, 2021
PM-2.5:
PM-2.5 concentrations early in the week are expected to be Good with localized Moderates increasing as we approach mid-late week.
FORECAST DISCUSSION:
Monday, December 6th, will be a rather windy day for all of Michigan as numerous Wind Advisories have been issued. A Low-pressure system to our north will provide a cold front that makes its way through Michigan today, Monday. The combination of the Low-pressure and cold front is the reasoning behind the windy conditions. Tuesday will have colder temperatures with highs in the 20s Fahrenheit with most of northern Michigan in the teens. The winds on Tuesday will be lighter and will be from the west. Strong winds Monday help to push out any PM-2.5 concentrations and westerly winds Tuesday help to keep the concentrations at bay.
Wednesday, winds shift to the SSW for much of Michigan which will increase PM-2.5 concentrations for the southern portions of Michigan. Going into Thursday, winds quickly shift to more SSE with temperatures in the low 30s Fahrenheit. Friday continues the trend of SSE winds with temperatures rising to the mid-30s for much of Michigan. Overall, PM-2.5 concentrations will be Good for Michigan this week, but there is a high chance of hourly Moderate concentrations come mid-late week.
EXTENDED FORECAST:
There is an increase in temperature as we approach the weekend with an increase in PM-2.5 concentrations as well, but conditions quickly change and decrease Sunday as another front makes its way through the region.
