A large nasty area of low pressure is threatening to create another significant December severe weather outbreak, this time in Minnesota and Iowa. How well will the nasty weather hold together? Does Michigan need to brace itself
At 953AM, ET, Grand Rapids was reporting overcast skies and a temperature of 50 degrees. Low pressure in the Plains was already working to pump warm air into the Great Lakes, leading to near record highs at this early hour. Snow melt was putting a lot of extra moisture in the air and leading to extra fog and clouds across the region. Eventually, there may be some clearing later today, but not much, even with aggressive southerly flow.
The rapidly developing, strong system in the Plains is also going to be very fast moving, with the associated cold front arriving in Michigan early tomorrow morning. Fortunately by that point, the dynamics of severe weather will be gone, and even the associated moisture will be drawn north to the center of low pressure. and little to no precipitation will accompany frontal passage. More typical December weather will follow on Thursday afternoon and into Friday, with clearer, colder but less breezy conditions.
