The Upper Midwest has had a consistent, cyclical pattern of late, generally transpiring over the course of a week or so. Warm over the weekend and through the early part of the week, then the threat of a little bit of precipitation, very cold by Thursday and warming up again for the weekend. It’s happening this week, and it happened last week in Green Bay. Forecasters generally saw that pattern and latched on to it in their forecast. The issue came down to temperature, as forecasters were a couple degrees too warm for where this cycle ended up falling in line. There was a three way tie atop the standings in the end, with the Weather Service, Weather Nation and Forecast.io splitting the winning share.
Actuals: Thursday – High 15, Low -7
Friday – High 31, Low 3
