Changeable Weather Ahead

Today marks the last day of weather "calm" for the region. High temperatures since Friday have been rather mild especially considering this time last week sub-zero readings were widespread. The first in a series of clipper system will affect the region this evening into tonight bringing light rain that will change over to light snow by the morning. High temperatures tomorrow will hold around the freezing mark which is near normal for this time of the year. Another system will organize over southern Canada on Thursday and move through the region on Friday. This system will have more strength and cold air than the first so it will drop temperatures to below normal levels.

Currently a weak system is over the Western Great Lakes and it will move quickly through the area overnight bringing a return to seasonable temperatures and light rain and then snow. No significant accumulations or lake effect are expected.

On Thursday a stronger system will be organizing over Southern Canada. This system will move south and east bringing more snow showers and colder air with it on Friday.

In the extended yet another pattern change is on the horizon. An upper level ridge is expected to rebuild over the Northeastern Pacific which will lead to a trough developing over the Eastern USA. This will return the area to well below normal temperatures and increased storminess, depending on the track of low pressure systems moving through the trough. As the pattern maintains and strengthens, the air moving south out of Canada will continue to get colder with each passing Arctic front.
