Today (Monday) marks the beginning of Meteorological Winter. Astronomical Winter occurs on December 21, which marks the shortest day of the year. The current weather pattern is living up the winter name with colder than normal temperatures following a weekend snowfall event unmatched in many years for this time of year. The cold weather will continue for the foreseeable future. In the Lower Peninsula, normal daytime high temperatures should be around 40 degrees with lows in the upper 20’s. It is unlikely that we will see temperatures north of the freezing point during this forecast period with low temperatures potentially reaching single digits Thursday night. Monday morning, Air Quality starts out in the Good AQI range. However, with a cold snowpack and lingering overnight inversions, some stagnation could drive concentrations into the Low Moderate range. While models are not showing any major storms heading our way, the National Weather Service is predicting a major lake effect snow event occurring on Monday night, north of Muskegon. Other lake shore counties will probably also see some snow but to a much lesser extent. A cold front is expected to drop south from Canada, Wednesday night, with some light snow accumulation expected. EXTENDED FORECAST: Air Quality is expected to remain Good to Low Moderate entering the weekend.
