A storm will bring a mix of rain and snow to Cape Cod, Massachusetts, and parts of Long Island, New York, on Wednesday while moderate snowfall extends from eastern Pennsylvania to Maine. Enough snow is expected to fall to make roads slippery in the coastal Mid-Atlantic. Accumulation in parts of New England may exceed 8 inches.
Farther south, a second storm will form near the Carolina coast. The system will bring snow from southeastern South Carolina to parts of North Carolina and southeastern Virginia. This may result in up to a few inches of accumulation in the northern part of the region.
Mainly dry, cold air will prevail in the East and the Central States. Some sleet and freezing rain may linger for a time in parts of South Texas. High pressure will build over the southern Plains.
Mild air is projected to linger west of the Rockies. Most areas from the Rockies to California can expect a dry and sunny day, with patchy low clouds and fog in the early morning. A storm from the Pacific Ocean will spread rain and mountain snow across Washington and parts of eastern Oregon. The moisture will then expand into much of the Northwest Wednesday night and Thursday. The same storm may bring warmer conditions to the Central States and the East later this week and over the weekend.
FOCUS: Rain and Snow in California Next Week
The jet stream is expected to dip south along the West Coast during the middle of next week. This will allow Pacific storms to bring additional rain and snow to parts of California, Nevada and Utah. It will turn colder.
