Cool, humid Sunday

Another great day for the indoors. Yesterday's low pressure system (see below) has moved northeastward and is now situated over Atlantic Canada. If you remember that the flow is counterclockwise and inward around the low, you'll see that this brings a flow of maritime polar air from the North Atlantic ocean across Quebec and into New England (see red arrows in figure at left). This keeps things cool, cloudy and humid, with a few showers.
