A fresh blast of arctic air will produce another round of lake-effect snow downwind of the Great Lakes during the middle of the week.
“With flow from the Arctic, ice-cold winds will affect the Great Lakes and all of the Northeast throughout the week,” said AccuWeather.com Chief Meteorologist Elliot Abrams.
These frigid Arctic winds will cause a lake-effect snow event to set up downwind of the Great Lakes.
The worst conditions are forecast to occur on Wednesday and Wednesday night with significant accumulations possible in areas close to the lakes.
In general, 6 to 12 inches of snow is forecast to fall from the heaviest snow near the lakes, creating major travel disruptions.
Those planning to drive across the region through Wednesday evening should anticipate snow-covered roads with the heaviest snow squalls producing white-out conditions for several hours at a time.
Conditions can quickly deteriorate along portions of Interstate 80 and the New York Thruway as the lake-effect snow bands develop and intensify.
“While the most intense banding will be localized, the potential exists for up to a foot of snow around Syracuse, New York, with higher amounts in the most persistent snow bands,” said AccuWeather.com Meteorologist Edward Vallee.
Although the most frequent bands of snow, flurries and squalls will be confined to areas closer to the Great Lakes, snow showers can reach all the way to the mid-Atlantic and New England coasts.
The passage of an arctic cold front will help to push snow showers well away from the Great Lakes on Wednesday into Wednesday evening.
According to AccuWeather.com Senior Meteorologist Alex Sosnowski, “It is possible a few locations are hit with a brief, but heavy snow shower on Wednesday that suddenly drops the visibility and quickly coats roads.”
Strong winds may flight arrival and departure delays.
Lake-effect snow should diminish heading into Thursday, but snow will not be absent from the region.
A disturbance swinging over the Great Lakes will spread light snow over the region on Thursday followed by another blast of arctic air on Friday.
Friday’s frigid weather will create yet another round of heavy lake-effect snow that will continue into the weekend, keeping people busy plowing and shoveling the fresh snow.
Some locations may have several feet of snow by the end of Saturday due to the persistent bands of lake-effect snow.
Despite the negative impacts that the snow will bring, there will be some positive impacts.
People planning to hit the slopes this weekend can expect favorable skiing conditions as the series of storms and lake-effect snow events bring fresh powder to ski resorts across the region.
Even in areas that do not receive a plethora of snow throughout the course of the week, temperatures should be low enough for ski resorts to create their own snow, helping resorts open up more trails and create a deeper snow pack following a mild end to 2014.
