While Lake Michigan snowstorm totals might not usually be as jaw-dropping as their Lake Erie or Ontario counterparts, there are some exceptions. 3-12, 2007, an incredible 141 inches of snow were measured in the town of Redfield, New York, about 50 miles northeast of Syracuse.Īverage annual snowfall (1981-2010 period) in the Great Lakes and Midwest. In 2007, however, even this snowbelt was overwhelmed. Three- to four-foot lake snowstorms are routine here each fall and winter. Furthermore, the Tug Hill Plateau rises steeply from the lakeshore, adding lift to the lake-effect band. Single bands of heavy lake-effect snow also form more often off this Great Lake due to its west-to-east orientation. Lake Ontario's depth allows it to be largely unfrozen even in the middle of winter, keeping it open to generating lake-effect snow. Even higher unofficial snowfalls have been recorded nearby, with the towns of Adams and Barnes Corners receiving 68 inches and 54 inches, respectively, on Jan. snowfall record, it does hold the official 24-hour snowfall record for the state of New York: 50 inches set in Camden on Feb.

Many of the snowfall records for periods of 24 hours or less are dominated by lake-effect snow events, primarily those from Lake Ontario. Lake-Effect Events Dominate Short-Term Snow Rate Records If the terrain rises appreciably from the downwind lakeshore, as it does in most Great Lakes snowbelt locations, that added lift to the air accentuates the snowfall. Feet of snow can pile up under this band, while just 10 to 15 miles away, only light snow falls, if any. When this occurs, you can get a single, narrow, intense band of snow, sometimes accompanied by thunder and lightning, dumping incredible snowfall rates over a small area for several days on end. The heaviest lake-effect snow events occur when a flow of air much colder than the unfrozen lake sets up over the longest stretch of the lake's axis, persisting as long as possible. 5, 2015, in this high-resolution image from NASA's Aqua satellite. but the National Weather Service says it is "increasingly likely" most areas on the Front Range will end on the low end of the snowfall forecast range.Lake-effect snowbands blanket the Great Lakes region on Jan. | SNOW FORECAST UPDATE | Denver's western suburbs and eastern Boulder County were downgraded to a winter weather advisory due to projected snowfall amounts expected on the lower end, according to the NWS.ĩ:57 p.m. While some roadways are slick and hazardous, the NWS said some winter weather alerts could be cancelled early.ģ:15 a.m. | SNOW TOTALS | While the NWS said snowfall rates haven't been "particularly impressive" the northern foothills have seen decent accumulations including 5 to 7 inches in eastern Boulder County.
