A seasonable and tranquil pattern will take shape over the Commonwealth this weekend and into early next week. Friday should see showers across the northwest and across the southeast portions of the state. A cutoff low should force chilly conditions and widespread showers across the state on Saturday, with perhaps some wet snowflakes as well in the Laurel Highlands. Northwest flow Monday and Tuesday, enhanced by a moisture-starved cold front Monday night, will result in partly cloudy skies generally across the state (with higher cloud cover near Lake Erie) and seasonably chilly temperatures. Fair conditions continue Wednesday before more unsettled and potentially much chillier weather returns late next week.
