Light Snow Chances...but Continued Cold

High pressure will be the dominating weather factor later this afternoon but another clipper system will quickly move in Wednesday bringing another chance for a few light snow showers.  As this passes to our east Thursday it will get caught up in the trough (or upper level low) that will continue to move through the northeast and eastern Canada.  A building high pressure system over Greenland the next couple of days will not allow the trough to make much progress eastward.  This will cause the low to actually move west into Canada reinforcing the colder air over much of the Midwest and Great Lakes.  Rotating along the edges of the low will be little disturbances that will bring the possibility of light snow Thursday and Friday. 

Once the high over Greenland starts to break down we might see a quick pattern change into early next week before it turns cold again towards to the middle to end of the work week.
