Bomb Cyclone Brings Heavy Snow, Winds and Arctic Cold

A powerful winter storm that intensified into a bomb cyclone is bearing down on the Great Lakes and the Northeast today, delivering heavy snow bands, damaging gusts and a sharp plunge in temperatures behind a strong Arctic front. Forecasters say the system will produce blizzard like conditions where heavy falling snow combines with winds that will reduce visibility to near zero at times and create prolonged disruptions to roads and airports.

National Weather Service forecasters describe the event as the product of a collision between frigid air surging south from Canada and unusually warm air that remained across the southern United States. That clash is fueling rapid deepening of the low pressure center and throwing a variety of hazards across a wide footprint from the Upper Midwest into the Eastern Seaboard. “Part of the storm system is getting heavy snow, other parts of the storm along the cold front are getting higher winds and much colder temperatures as the front passes. They’re all related to each other, different parts of the country will be receiving different effects from this storm,” said Bob Oravec, lead forecaster at the NWS office in College Park Maryland.

Models and meteorologists show an additional one to two feet of lake effect snow is possible in the heaviest bands downwind of Lakes Erie and Ontario through Wednesday, with some lake effect bands persisting through New Year’s Day. The Midwest Regional Climate Center notes the criteria for blizzard conditions include sustained winds or frequent gusts of 35 miles per hour or greater and falling or blowing snow that reduces visibility to less than one quarter mile for three hours or longer. Forecasters warned that the combined wind and snow threat will meet those criteria in parts of the Great Lakes region.

The storm is already affecting infrastructure. Poweroutage.us recorded more than 153,000 customers without electricity early Tuesday, with more than a third of those outages in Michigan. Officials and utilities are preparing for additional outages as wet heavy snow and strong winds bring down trees and lines. The NWS is also warning of subfreezing overnight lows as far south as the Gulf Coast and has issued Freeze Warnings Watches and Cold Weather Advisories across broad swaths of the South and East.

Economic and market implications are unfolding in real time. Elevated demand for electricity and natural gas to heat homes and businesses could pressure regional markets and push spot prices higher during the cold snap. Transportation disruptions are likely to dent holiday travel spending and delay freight deliveries for retailers still operating in the holiday window. Municipalities will face heightened snow removal and emergency response costs, and insurers can expect a surge in claims tied to wind damage and downed power lines.

Officials urged residents to heed local warnings prepare for extended travel disruptions and power outages and protect against extreme cold. With the storm expected to linger in lake effect zones for multiple days the economic and safety impacts could extend well into the new year as crews work to restore services and clear major highways.
