Our active winter pattern continues this week across the region. Another cold front is right on our doorstep, which will yet again bring in some colder air into the area.
In the meantime, at the 10 p.m. Monday analysis, winds were picking up out ahead of a cold front. Our area was picking up some warm air advection thanks to a warm front that passed to our north. Even at 10 p.m., many areas in our region were still in the 40s, which is much warmer than we have seen over the last few days. However, a cold front extended basically from Cincinnati down to near Nashville, with colder air behind the front. That cold front will pass through our region Tuesday morning, which will rid us of the warmer temperatures.
With that cold front will be some light precipitation in our region during the morning hours of Tuesday. Though the model below is showing all snow for our area at 7 a.m., I anticipate most of this to be a rain/sleet mix that will slowly transition to snow as the cold front passes through our region. By the early afternoon, the front will have passed our region, and by then, we should all be below freezing, so any precipitation that falls will be in the form of snow.
During the afternoon and evening, we’ll see upslope snow from Lake Michigan fall across our region thanks to a stiff northwesterly wind. That upslope snow will last through the evening hours and into the early morning hours of Wednesday, allowing for a light accumulation of snow in the lowlands, with better snowfall totals in the highlands.
For my snowfall forecast, I’m going with a light dusting to an inch of snow for the lowlands between now and Wednesday morning. The areas with around an inch of snow will be the areas impacted by lake effect the most. 1-2″ will be possible along the I-79 corridor, with more snowfall likely in the highlands.
Weather conditions will improve by Wednesday afternoon, but the active weather pattern looks to continue on as we head toward the end of the week.
