FORECAST DISCUSSION: After a flurry of mixed precipitation yesterday, March 26th, with snow in the north and steady rain in the south, us Michiganders get a break in weather for the weekend ahead. Aside from a slight disturbance potentially bringing light precipitation overnight tonight and Saturday night, High pressure slides in Saturday morning which will clear the skies but may bring breezy conditions come Saturday afternoon and evening. Temperatures will increase throughout this weekend as well with the mid-30s to mid-40s on the docket for Saturday and the mid-40s to mid-50s on Sunday. The warmth will continue early next week, at least for southern Michigan, as the 60s look to make a return. For air quality, the breezy conditions and change in wind direction will help to keep our current airmass continuously clean and prevent any PM-2.5 buildup. At the tail end of this weekend and into early next week, there may be a slight increase of PM-2.5 into the low-Moderate range as southerly flow returns and wind speeds start to slow down. However, overall air quality this weekend is expected to be in the Good range. EXTENDED FORECAST: A run at the 70s looks possible Tuesday next week along with the potential of heavy rain. Air quality will remain in the Good to low-Moderate range.
