Well the clipper system brought some snow to much of PA last night, but accumulations were pretty limited with Pittsburgh seeing the bulk of snow with between 3 and 6 inches. Light snow looks to potentially linger on during the day today in western PA as most locations should see an inch or two at most. Mostly sunny skies will push in on Wednesday. The DC Region will see a mix of rain and snow today and tonight, with potential for some accumulation to the north of the city. Could see 1-3″ of snow to the north of DC with possible higher amounts up towards Frederick and northern Maryland. Light snow could continue into early Tuesday before mostly sunny skies move in on Wednesday.

Lows in the mid 10s to low 20s tonight will drop into the upper single digits and 10s tomorrow night before mid 10s to low 20s return Wednesday night. The DC Region will see highs afternoon highs in the mid to upper 30s today and tomorrow before low to mid 30s settle in on Wednesday.

Worst of coastal storm for NYC and Boston comes later this afternoon/evening and into early Tuesday. Snowfall rates over 1″/hour possible as winds could gust over 60 mph. If you live in NYC, Long Island, Connecticut, Rhode Island, Massachusetts, southern New Hampshire, and southern Maine, prepare to get a hefty amount of heavy, wet snow.
