The aforementioned frontal system is expected to pass during the early afternoon hours of Saturday.  Temperatures will begin dropping and by Sunday, high temperatures will only reach the high 30’s.  With the warmer lake waters, it would not be surprising to see some lake effect showers on the west side of the state.  After the front passes and for the rest of the weekend, we can expect GoodAir Quality,
