Buffalo, New York – Cold air flowing across Lake Ontario is producing light lake-effect snow across western New York today, with minor accumulations expected along the shoreline and potential travel impacts on major routes including Interstate 190 and the New York State Thruway.
According to the National Weather Service in Buffalo, northwest winds over Lake Ontario will generate periods of light snow this morning, particularly across areas closest to the lake. Forecasters expect 1 to 3 inches of fluffy snow along the southern Lake Ontario shoreline, while locations farther inland should see an inch or less.
Snow activity is expected to gradually weaken through the afternoon as lake influence diminishes. However, untreated roads and elevated surfaces may become slick during the morning and midday hours, especially near the shoreline and along north–south oriented roadways exposed to lake-effect bands.
The National Weather Service notes that snow showers should taper to flurries by late afternoon, improving visibility and road conditions heading into the evening. Despite the lighter nature of the snow, cold temperatures will limit melting, allowing snow to accumulate quickly even during brief bursts.
High temperatures Sunday are expected to remain cold, with readings generally in the teens and lower 20s across the region. Wind chills will make conditions feel colder, particularly in open areas near the lakeshore.
Motorists traveling along I-190, I-90, Route 5, and nearby secondary roads are advised to slow down and maintain extra following distance, especially during periods of reduced visibility. Commuters should allow additional travel time where snow showers briefly intensify.
No significant additional snowfall is expected once lake-effect activity winds down, but forecasters caution that winter driving conditions can persist even after snow ends.
Residents are encouraged to monitor updates from the National Weather Service as lake-effect snow bands can shift quickly and create localized impacts.
