Weather Tidbits: Continental Polar Air Mass

The continental polar air mass is checked out in this Weather Tidbits. A continental polar airmass or cP is a cold, dry, stable air; that originates around 60° N. It’s associated with rapid rational cooling in winter; but areas along the Great Lakes deal with lake-effect snow, as the air mass collides with the warmer waters. The air mass acts different in summer; by bringing lower humidity and comfortable temperatures.
