Off Lake Erie, lake snows will oscillate between the Buffalo Southtowns and the Boston Hills today, then lift north and weaken tonight. Off Lake Ontario, lake snows will remain in the Tug Hill region with some subtle oscillations through tonight. Gusty winds will also produce blowing/drifting snow and near whiteout conditions at times, making travel within the snow bands hazardous.
Extreme cold is possible Friday through this weekend. Daytime highs in the single digits, and overnight lows well below zero. Lowest wind chill values as cold as 20 below across western New York and 30 below east of Lake Ontario.
Another round of Arctic air will move into the region Friday and last through the weekend. Proper precautions should be taken when preparing to head outdoors.
