We have the Alberta Clipper centered a little north of Lake Ontario. With the front we have a warm front draped over New York State and southern New England, with an approaching strong cold front from the west. Ahead of the front temperatures are seasonal across northern areas and slightly above average for southern areas. As the clipper continues to move east, it will deepen and winds will increase. During the afternoon into tonight winds of 20-30 mph with gust of 40 to 50 mph will be possible. The clipper has brought several inches of snow to western and northwestern New York State. As the snow continues to push south and east snow amounts will fall as the snow more or less falls apart, but there will be scattered to isolated snow showers.  Lake effect snow bands east of the Great Lakes will drop south and east tonight bringing a few inches of snow southeast of the lakes, especially Lake Ontario. The bands will sit there during the overnight before lifting back north and weaken during the day.

The system will pull away tonight into tomorrow, as high pressure builds in, it will it will cool down as a brief burst of arctic air moves in overhead, temperatures over northern areas being below average with the southern areas seeing temperatures drop back to seasonal. Away from Lake Ontario the rest of the region should be quiet. Thursday night low pressure will be approaching, with the warm temperatures this will be a rain event for much of the region. Rain will move into Southwest Pennsylvania later Thursday evening, these rain showers will work there way east during the overnight, reaching the Middle Atlantic Friday morning, then moving into southeast New England by Friday afternoon.  During Friday Pennsylvania, Maryland, Delaware, New Jersey, Southeast New York State and Southern Connecticut, Rhode Island and southeast Massachusetts this will likely stay all rain. Those north of I-90 could see a mix/snow. Then as the colder air comes in behind the system, rain and mix will see a change over to some snow across northern Pennsylvania New York State and across northern New England into northern Connecticut.  There going to be a chance for some ice for the Catskills, Poconos, into parts of the southern Hudson Valley and northwest New Jersey.

The weekend will be cold as high pressure sits overhead. Sunday the high pressure will start to push east, ahead of another area of low pressure approaching, the clipper looks to be weak. High pressure moves in for Tuesday, than another area of low pressure will move through for Wednesday.
