WEST MICHIGAN — After sunshine and temperatures well into the 50s on Monday, a strong cold front blasting through the state will usher in sharply colder air on Tuesday. In fact, our warmest temperatures on Tuesday occur at midnight in the upper 40s/low 50s, then tumble into the low/mid 30s around daybreak. We only expect a rebound on Tuesday afternoon around 40 degrees. If that wasn't bad enough, strong winds from the west-northwest at 15 to 25 mph with gusts around 40, will generate wind chills in the 20s most of the day!
Take a look at forecast wind speeds on Tuesday at noon in the image below. The larger, whiter numbers are sustained winds. The "G" number is the wind gust. The arrow represents a northwest wind.

Our forecast model image below shows temperatures at 6 P.M. on Tuesday in the larger, whiter number, and the WC represents the wind chills or feels like temperatures. Most of these are in the 20s!
The only good news? We expect mostly sunny to partly cloudy skies. By Wednesday morning, another low pressure system will slide into the western Great Lakes and may generate a strip of accumulating snow across southwest lower Michigan. Specifically, from Grand Rapids off to the south and west. Anywhere from a dusting on grassy areas, up to an inch or two may fall across Allegan, Van Buren, Cass, and Kalamazoo Counties. We expect to warm into the upper 40s Wednesday, and rain showers will be possible later in the day, evening, and at night into Thursday morning. See our forecast model below valid for 6 A.M. Wednesday.
Normal highs for this time of year have us at 60 degrees. All of this week is expected to remain below that number. More rain showers are likely this weekend. Get the complete West Michigan forecast at www.fox17online.com/weather.
