This forecast was by far one of the most complicated forecast we’ve had so far this winter. In the days leading up to the event there was a large discrepancy in storm track, one which would send the heaviest snow north of a Macomb to Ottawa line with the other solution much further south keeping the heaviest snow along I-72. With very little movement in the models, it seemed likely that the actual solution would be somewhere in the middle, placing the heaviest snow somewhere in our local area. The lack of model consensus and the relatively narrow nature of the heavy snow swath resulted in more uncertainty in the forecast than we would typically have 24 hours out, therefore, our projected ranges were larger than we would typically see.
On Wednesday the forecast called for a widespread 4-9 inches of snow with a narrow band of 5-10 inch totals located along a Havana to Bloomington line. Throughout the day the storm track was shifting south and beginning to line up with our projections, however there was concern that this southward trend would continue heading into Thursday morning displacing the heavier snow slightly further south than where we expected it to be. As the Wednesday evening models began to filter in, there was another noteworthy southward shift in storm track. So, we adjusted the band of heavier snow another 10-15 miles south.
In the end most areas received their expected amounts of snow. It turns out the final adjustments made Wednesday night were unnecessary as the previous forecast was just as accurate as the final call. Most areas who where expected to see 5-10 inches of snow ended up between 7 and 9 inches. The most impressive snow report came from Manito with 12 inches reported, 2 inches of which fell in 45 minutes as a heavy band of snow moved across the region.
