Today's weather: II Marine polar (mP) air mass

Cool, damp weather almost always means we're under the influence of a marine polar (mP) air mass miving in from the North Atlantic Ocean. Coastal New England sees this type of air far more frequently than Vermont, but Vermont has its fair share of foggy, drizzly days due to mP air masses. The map at left shows that we need easterly or northeasterly winds to bring this air into Vermont.
