(8:45AM - 4/17/20) A brief update regarding the snowstorm that continues to affect the state this morning.
Snow continues to fall this morning across a good portion of Northern Illinois, while it has come to and end across affected portions of Central Illinois. As is usually the case, some areas over-performed and some areas under-performed with snowfall accumulations. Additionally, this event ended up further north than expected, and given our forecast was already on the north side of model guidance, there was nothing much we could about that.
As of 8AM reports show upwards of 4-8" of snow has occurred across portions of Western Illinois, south of I-80. Additionally, a larger swath of 2-5" has occurred over much of Northern Illinois, with snow still falling across much of this area. A few of the high snowfall reports across the state thus far are: 7.0" Burlington, IA - 6.4" Knoxville, IL - 5.5" Galesburg, IL - 5.0" Altona, IL - 4.6" Milledgeville, IL - 4.3" Streamwood, IL - 4.0" Crystal Lake, IL
Below are two maps; one on the left being our final forecast from yesterday, and one on the right being observed snowfall totals as of 8AM.
