Why the warm weather?

Posted:

MADISON (WKOW) -- The weather in Wisconsin has been unseasonably warm here for the past few weeks. But why have the temps been so high?

Dr. Jonathan Martin, the chair of the UW-Madison Department of Atmospheric and Oceanic Sciences, says the jet stream has retreated far to the north allowing plenty of warm and tropical air to be transported into the northern U.S.

This warm weather also has people wondering about climate change. Dr. Martin has no doubt in his mind that climate change is occurring and playing a role in the record warmth.

Although, this early warm weather doesn't necessarily mean a more severe weather season. While warm air is one ingredient for severe weather, rising air and a clash of warm and cold air masses is needed for severe storms to develop. Clearly the cold air is no where to be found across the Midwest.
