Say goodbye to arctic cold and hello to above average warmth. Over the next few days the upper level ridge that has been keeping it cold and dry will be pushed east.
By this weekend a new pattern will take hold. The cold will exit and above average temperatures will return to the eastern half of the US. This will lead to storm development across the southern plains that will move northeast towards Wisconsin. This has the potential to be a major storm system and current simulations suggest snow north, rain south Sunday and Monday. The details will change with many days left before the event.
The Climate Prediction Center is forecasting high likelihood of above average precipitation across Wisconsin in the 6-10 Day period. A similar trend persists in the 8-14 day period, suggesting there may be more than one major storm chance in late January.
