A cold front will push through the Twin Tiers Friday night with rain expected to change over to snow showers.  A second area of low pressure will develop along the front helping to enhance some of the snow late Friday night.  Temperatures will drop into the lower 30s resulting in an elevation dependent snow accumulation.  Valley locations will pick up 1-2" while higher elevations could end up with closer to 4".  Scattered snow showers will continue at times through the weekend.
