Temperatures will be about 20 degrees below average into Sunday morning.
High pressure building in will dry things up but also keep the colder air in place.
High temperatures on Saturday only made it into the upper 30s and low 40s. Buffalo had a night temperature of 41 degrees F. The average is 57.
Temperatures Saturday night will drop even more, down to the upper teens for parts of the Southern Tier, and mid 20s elsewhere.
