Cold and wintry weather continued in the Great Lakes region on Tuesday as the storm system impacting the region moved northeastward into southeastern Canada.

Blustery winds wrapping around the system spread cold air from the north across the Upper Midwest and maintained well below normal temperatures for this time of year. As cold air surged across the warmer waters of the Great Lakes, lake-effect snow showers formed downwind of the lakes in areas of Wisconsin, Michigan, western Pennsylvania, and upstate New York.

Shifting focus to the East, a mess of wintry precipitation spread further into the Northeast on Tuesday as a second storm system lifted northeastward from the Midwest and moved off the southern New England coast by the afternoon.

As this system progressed, cold air over the Northeast supported snow showers mixed with areas of sleet and freezing rain through the morning hours. Precipitation in southeastern New England changed over into mostly rain showers by the afternoon as a warmer airmass associated with this system spread in from the south.

As this system picked up moisture, heavy snow shower blanketed the northern and interior regions of the Northeast on Tuesday, leaving behind up to a foot of snow through Tuesday. In addition to snow accumulation, many areas experienced up to a tenth of ice accumulation due to sleet and freezing rain.

Meanwhile, an associated cold front reached across the Mid-Atlantic and southeastern corner of the nation and pushed toward the Atlantic Ocean through the day. This front was fairly weak and only stirred up scattered showers and isolated thunderstorms due to limited instability.

Out West, scattered showers and high elevation snow began to spread into parts of northern California and the Pacific Northwest late Tuesday afternoon and evening as a Pacific storm approached the Coast.
