It’s just another frigid January morning for the Northern Tier. In fact the coldest of winter so far for some! Helped of course by snow cover and a 1044 high.

Tomorrow am looks coldest for some parts of OH, MI, PA, western NY.

What’s coming!

Based on the large-scale hemispheric pattern shift with -AO returning along with -NAO/-EPO, the models are seeing the rebuilding of the AK/Arctic Canada high and therefore Pacific warming is all but temporary with much colder, Arctic air soon to return as we head towards late January.

Models see the return of snow.
