Another round of moderate to heavy snow is on the way, look for the snow to become steady by late tonight and remain through the overnight and early a.m. hours. 2-3" possible from overnight through a.m. The morning commute will be messy.
Snow will then transfer to lake effect snow by late afternoon. Heaviest snowfall will be once again in the South towns and S. Tier. Snow will fall right through Wednesday a.m. for Buffalo Wednesday p.m. for S. Tier. Snowfall totals 4-8" 15-20" for the S. Tier and south towns.
By Wednesday afternoon the snow will taper off for the City of Buffalo, but continue for the S. Tier. Temperatures will be very cold with highs only in the upper teens with wind chills in the single digits.
