Chilly conditions in store for weekend

Polar air continues to move into our region, and the first frost looks imminent tonight. In fact, temperatures could reach the freezing point outside Boston! A high pressure sitting in the Midwest is pulling cold air from Canada down into New England. Winds should be somewhat stiff today as well, but will subside on Saturday. By that time, the high pressure will reach us and provide clear, dry conditions. The cold temperatures will not last long because a low pressure will approach the Great Lakes, pushing warm air into the Northeast by Monday. Any significant rain chances should hold off until late Sunday. So the jacket is a better choice over the umbrella this weekend.
