An active week of weather is in store for the Philadelphia and New York City metropolitan areas which of course lines up with the most active week of travel in the United States, the week of Thanksgiving. This week the northern Mid Atlantic will experience record high temperatures (today) with highs in the 60’s and 70’s, rain, and then snow. Then to end the week, below normal temperatures. You get every thing, just like a Thanksgiving dinner!
A warm front will continue to lift north this morning with periods of moderate to heavy rainfall expected.

High pressure from the Great Lakes will briefly be in control tomorrow morning with scattered clouds before clouds begin to increase through the afternoon and evening. An area of low pressure in the Gulf of Mexico will intensify and lift northeast towards the coastal waters of South Carolina by tomorrow afternoon leading to the increasing cloud cover.

The area of low pressure will lift north towards the New Jersey coastal waters by Wednesday evening. Periods of rain and snow will move into the region. The rain/snow mix will change over to rain along the coast on Wednesday while a winter mix will continue over the interior. Cold air will slowly work in from the interior to the coast leading to the wintery mix to first go over to all snow. By the time the cold air reaches the coast, most of the precipitation will be done leading to just a few snow showers or a period of light snow on Thanksgiving morning.
