FORECAST DISCUSSION:
The first full week of April is upon us, and it looks like Michiganders will have to wait a few more days to see warm April weather. A cold front drops down from our north throughout the day today bringing north-northwesterly winds and snowfall for the entire state. The upper peninsula and northern lower peninsula will see most of the accumulation with mid-Michigan and southward only seeing flurries with trace amounts of accumulating snow. The cold front leaves clear conditions in its wake for Tuesday and a good amount of Wednesday before another Low-pressure system approaches the Great Lakes late Wednesday and kicking up rain showers for southern portions of the state. Once we get through the first half of the week, there is a rather steady incline in temperatures which will carry us into the weekend ahead. For the latter half of the week, we will see High-pressure hanging around with winds coming from the south—providing temperatures returning to the 50s and 60s.
Northerly winds for the beginning half of the week will help keep air quality in the Good range as there appears to be little to zero smoke or dust in the area to impact PM-2.5 concentrations and it is still too cold for Ozone to develop. Once we get into the latter part of the week, warmer temperatures may bring hourly Moderate concentrations for PM-2.5 These concentrations will mainly be contained to the morning rush hour timeframe with dissipating concentrations throughout the day. It should be noted that there are current fires burning in southern plain states, so there will be continued smoke entering the atmosphere. As of now, this smoke does not look to impact Michigan, but smoke concentrations will be monitored. Ozone may see an increase towards Moderate, but it will still be too cold for any real Ozone development.
EXTENDED FORECAST:
As mentioned above, warm and clear conditions look to be on deck for the weekend ahead. Air quality is expected to remain in the Good range.
