Widespread snow, rain and strong winds developed overnight as a winter storm rapidly developed over the Northeast and northern Mid-Atlantic regions. Heavy snow across portions of New York have already exceed a foot in a few locations with more forecast today. Heavy rain is expected for southern New England, especially for coastal areas from New Jersey to eastern Massachusetts. Wind speeds have increased in response to the strengthening of the main low pressure system offshore New Jersey. Widespread high wind speeds will persist through the late morning and afternoon hours today as the system moves offshore the East Coast. Inland flooding from the excessive rainfall and coastal flooding from high seas/storm surge will impact much of the area from New Jersey to Massachusetts. Numerous warnings are in affect for the Northeast and Mid-Atlantic, including: Winter Weather Advisories, Winter Storm Warnings and High Wind Warnings. Snow and rain will taper off by late Friday/Saturday morning as the system tracks further out into the Atlantic Ocean.
Cold and snowy conditions will persist across much of the West into the weekend as a cold front pushes eastward toward the Rockies. Heavy rain will likely set up along the coastal areas of the Northwest and portions of northern California with heavy mountain snow across the Sierras and other ranges across the Great Basin and Inter-mountain West. Locally heavy rain is expected along the southern coast of California which may pose flooding concerns this morning, especially over burn scar regions where flash flooding will be possible. Portions of the northern and central Rockies likely seeing up to a foot or so of new snow through Saturday.
