PHILADELPHIA (CBS) — An active jet stream will allow for an area of low pressure to track northeast and intensify as it moves off the Virginia coast Wednesday night. The storm will brush the Delaware Valley with a period of rain changing to snow Wednesday night. Expect clouds to increase during the day on Wednesday with rain developing between 3-6 p.m. with high temperatures well above freezing in the mid 40s.

During the evening, colder air will return as the storm intensifies, changing the rain over to wet snow. The snow will continue through late evening and come to an end a little after midnight. Accumulations of about 1-3” are expected, but amounts will depend on how quick the changeover to snow occurs and how heavy it falls. Temperatures will have been well above freezing, so it may take some time to accumulate on the roads.

Lows on Wednesday night will be near freezing.

The storm will be long gone for Thursday, so expect some sunshine with highs back in the mid 40s.
