WEST MICHIGAN — While some areas in our southern counties made the lower 60s on Saturday, it was generally a dull, gray, foggy day with a few light rain showers and drizzle. As a warm front lifts through the state Saturday night/Sunday morning, look for temperatures to soar in to the upper 50s (north) to middle 60s (south) on Sunday across our FOX 17 viewing area.
The record high in Grand Rapids for December 13 is 57 set back in 1920. It’s likely we break that! The record high for Muskegon is 60 set back in 1975. We should at least tie that. The record high temp for Lansing is 56 set back in 1975. That record should fall too!
The map attached to this story with the numbers were the high temperatures on Saturday across the Midwest and Great Lakes. We’ll maintain a southeast to southerly flow on Sunday likely sending temperatures in many locations in to the 60s! Unfortunately the day will come with extensive cloud cover, areas of fog, and some light rain or drizzle. The image below is from our computer forecast model and is valid for Monday morning at 6:00 AM. Note the big low pressure system in Wisconsin bringing up rain and warmer temperatures. Michigan will remain in front of this system in an area meteorologists refer to as the warm sector (between the warm front and cold front). That means all of our precipitation will be liquid. The steadiest/heaviest rain will likely occur Sunday night in to Monday morning.
Once the system slides to our north/east, look for temperatures to fall throughout Monday and cooler air to filter in behind the low. That said, highs on Tuesday will still be above normal in the mid/upper 40s. We’ll see more mild air on Wednesday with more rain chances from another system that will eventually deliver sharply colder air and lake-effect snow showers Thursday, Friday, and Saturday (accumulations possible) with highs in the upper 20s/low 30s.
