Freeze warning in effect through Wednesday morning

A freeze warning will be in effect tonight from 9 p.m. until 9 a.m. Wednesday morning for Northern Erie, Niagara, Orleans, and Genesee Counties.

A strong fair-weather system parked north of the U.S./Canadian border will continue to act as a brick wall to any unsettledness. It will also keep unseasonably cool air over the region, though there will be some slight moderation toward midweek.

Things start to change toward midweek as a widespread system heads our way. Clouds from that increase Wednesday afternoon and showers push in overnight Wednesday night into Thursday, though they will become spotty for the afternoon. Another shot of chilly air triggers bands of localized lake effect showers with most of it just south of downtown Buffalo and near Lake Ontario for Halloween and Saturday.
