The beginning and middle of the month of December were rough, to say the least. The second major system featuring severe weather started in the northern Plains, and reached the Great Lakes by our December 16th forecast time in Grand Rapids. There was a gust of nearly 60mph, even outside any precipitation on Thursday the 16th. Temperatures, which started in the low 60s on Thursday were ready for a decline, dropping 35 degrees for Friday. Even though the weather was bad, forecasts were generally good. The Weather Channel had the best temperature forecast, but Forecast.io drew level as they were one of only two not to have rain in the forecast.
