Forecast Discussion: FORECAST SUMMARY: Monday, February 23rd, 2015 through Monday, March 2nd, 2015 PM-2.5: 24-hour Fine Particulate concentrations are expected to be mostly Good to some Moderate through the forecast period… FORECAST DISCUSSION: A continuation of below average temperatures can be expected through the forecast period with a combination of Good to Moderate particulate concentrations… High pressure on Monday will give way to an approaching Arctic front on Tuesday. As that front passes through the state during Tuesday evening and Wednesday morning, a few inches of lake effect snow may fall in the Lake Michigan counties but most will just see an inch or two through Wednesday. Any lingering Moderate readings should shift to Good following the frontal passage. High pressure will dominate the region from late Wednesday through Saturday. Cold temperatures will prevail with light northwest winds. The Air Quality should be generally Good with a few scattered Low Moderates where local stagnation has a tendency to occur during the early morning hours. A warm front settles over the Michigan/Indiana border for Sunday into Monday. This will allow some warmer air to enter the state. Warmer air over the existing cold snow pack, along with frontal trapping of air at the surface could lead to some Moderate concentrations of fine particulates. The associated cold front will move through and clear things out for Tuesday with cold northwest winds. EXTENDED FORECAST: Air Quality should remain mostly Good into the next week.
