This weekend’s weather will be a tale of contrasting temperatures and airmasses. The week ends with warm temperatures more than 10°F above normal. A cold front sweeps through and fall returns for the weekend itself, but another warm up takes place leading into Monday. Also, Daylight Saving Time ends at 2AM Sunday.

Rest of today – increasing clouds for the day. Warm with high temperatures in the mid-70s. Yesterday, a warm front pushed through, putting us in the warm sector associated with a low pressure now over northeastern Quebec.

Saturday – quite a different feel tomorrow once this cold front below moves through the area. Winds will become onshore from the east, bring much cooler air. High temperatures are expected to top out only in the upper-50s with sunny skies (around normal for this time of year).

Sunday – there’s a chance of showers overnight Saturday into Sunday associated with the next storm system to impact the area. An advancing warm front is expected to bring light, stratiform rain ahead of it. Temperatures will be warmer, in the mid-60s with mostly cloudy skies.

Monday – the familiar pattern of warm front followed by cold front continues Monday. We’ll again be in the warm sector with temperatures peaking at about 70°F. Rain should accompany the passage of this cold front.
