Cold shots and possible snow
Friday January 30, 2015

When storm systems in the northern hemisphere (where we are)
are well formed they begin to rotate counterclockwise (like a hurricane). When this happens a flow of warm air and a flow of cold air begins. When the storm passes to the north or west of a city, the city stays in the "warm sector" of the storm. When the storm passes to the south or east of a city, the city stays in the "cold sector" of the storm.

Storm "L" is to the north and west of city "B", so "B" is in the "warm sector".
Storm "L" is to the south and east of city "A", so "A" is in the "cold sector".

This morning's storm passed to our south and east. As a result we are now in the "cold sector" behind the storm. Tonight's temperatures will fall close to zero degrees. Winds may make it feel below zero in the morning. As the storm moves further away temperatures will moderate some for Sunday.

A new storm system may move across the region during the day on Monday. Currently, this storm has the potential to produce a moderate snowfall across the region. This storm would again be centered to our south and east, so following it we will likely see a renewed shot of cold air. This second round of cold air could be the coldest of the season so far.
