We are starting to see more signs in the next week of a much colder temperature trend developing. For the Tuesday-Wednesday time period of next week (January 22-23), the jet stream will allow cold air to drop southward from Canada.
The core of the coldest (arctic) air will stay across southern Canada and the Great Lakes. However, for our area, we could potentially see the coldest highs of the winter season so far, possibly not getting out of the 30s.
It does appear that this will be a glancing blow, and that the cold air will get ejected east of us by later next week.
