Forecast Summary:
Monday, March 21st, 2022, through Monday, March 28th, 2022
PM-2.5: PM-2.5 concentrations are expected to range from Good to low-mid Moderate this week.
FORECAST DISCUSSION:
The week starts out with temperatures in the 60s for mid-Michigan and southward, with areas to the north creeping into the low-40s. A warm front somewhat stalls over southern Michigan today, Monday, which is the reasoning behind the warmer temperatures appearing to stay in the south. This warm front is associated with a low-pressure system that will gradually approach the region during the early part of the week. It will provide rain and some possible rumbles of thunder mid-week on Wednesday for southern portions of the state. Scattered rain and snow, to the north, continues into Thursday with temperatures dropping down to the low-mid 30s throughout Michigan. As we approach Friday, temperatures hang around the mid-30s with scattered rain and snow in the late afternoon timeframe.
Saturday continues the trend of temperatures in the 30s, but the winds pick up from the northwest providing colder air going into Sunday. PM-2.5 concentrations are forecasted to approach hourly Moderate levels in some southern Michigan areas earlier in the week. Mentioned above, as the low-pressure system makes its way into the area mid-week, this will clean out any PM-2.5 buildup that occurs. The increase in winds on Saturday will also help push out any concentration build up that occurs late-week.
EXTENDED FORECAST:
The start of next week appears to have two high-pressures to the north and south of Michigan providing somewhat stagnant conditions but overall air quality looks to remain Good.
