Lake-effect snow showers and flurries will fly across Great Lakes and Northeast tonight into Friday for perhaps the last time this season.
As we head deeper into March and closer towards spring, intrusions of cold air become less and less frequent, thus limiting lake-effect snow.
In addition, the battle between warm and cold is often won by the warm air, again limiting lake-effect snow.
Still, if a bit of cold air can pass over the Great Lakes, like it will tonight and Friday, a bit of lake-effect snow can develop.
A strong cold front will blast through the Northeast tonight into Friday and much cooler air will push into the region behind the front. The springlike warmth that surged into the East will be a distant memory, at least for a time.
Due to such an unusually mild winter, most of the Great Lakes are still unfrozen, giving the opportunity for lake-effect snow showers and flurries.
Areas downwind of Lake Ontario will have the best chance of seeing a coating to an inch or two of snow on Friday.
Residents who will be traveling in these areas should use extra caution while driving on snow-covered roads and should watch out for slick spots.
Looking ahead, high pressure will build into the region for the weekend and another springlike surge of warmth will return for the start of next week. There are signs that this return of warmth across the central and eastern United States might not leave anytime soon.
