Heavy End of the Year Lake Effect Snow

Heavy lake effect snow impacted the west to north wind snow belts beginning Friday, December 29th through Saturday, December 30th. Along with the accumulating lake effect snow, dangerous travel conditions unfolded as white-out conditions were observed in the heavier bands. With strong and gusty west to north winds during this event, wind chills of 15 to 25 below were observed along with blowing and drifting snow.

This event is a great reminder that lake effect snow events, especially when meso-lows are involved, can be highly variable over short distances and lead to rapidly deteriorating conditions within a matter of minutes!
