URGENT - WINTER WEATHER MESSAGE National Weather Service Cleveland OH 551 PM EST Thu Dec 24 2020 ...Winter Storm to Bring Widespread Snow Tonight Before Transitioning to Lake Effect Snow... . A strong cold front has moved just east of the region and has set the stage for a winter storm as low pressure moves north along the front through the Appalachians. The mixed wintry precipitation has quickly changed to snow this evening and will become moderate to heavy at times east of I-77. Most of the synoptic snow will fall from around sunset through about daybreak on Friday. As this low departs, snow will transition to lake effect snow on Friday across Northeast Ohio and Northwest Pennsylvania. Lake effect snow bands will begin fairly scattered before intensifying through Christmas day and continue into Saturday. The best snow accumulations for lake effect at this time appear to be near the lakeshore. Westerly winds with gusts to 30 mph may allow for blowing snow, which could significantly reduce visibility and could cause drifting on north-south roadways. The strongest winds will be closest to Lake Erie. Temperatures will quickly fall into the 20s tonight behind the cold front.
