Heavy rain will be ending sooner than anticipated because of the storm's forward speed. That's good news for the morning commute.

Heavy Rain Ending, Breezy with Rising Temperatures
Temperatures: 40s and 50s
Rain: 2-3 inches
Morning Rain Changing to Snow Dhowers, Gusty and Colder
Temperatures: 40s to 30s
Snow: Up to an inch NW Surburbs
Mostly Sunny,Quite Breezy at Times
Highs: Mid 30s
Wind: NW 10 m.p.h.

A developing winter-like storm system over the Southeastern U.S. will continue to strengthen as it moves across the lower Chesapeake Bay, on a track that will take it to the New England coastline later tomorrow. Along the way, it will be pulling tons of moisture from the Gulf of Mexico and especially the Atlantic Ocean. The increased speed of the system will mean the heavy rain will end in the early morning hours...before 3 am. But periods of rain will continue through the morning rush.

When the storm center passes north of our latitude, winds will veer to the northwest. This will draw colder air into the back side of the departing storm, And as the storm interacts with strong high pressure building over the Central Plains, the winds will increase. This process increases the chances many parts of the area will see the rain mix with or change to snow tomorrow afternoon. And on the huge travel day Thanksgiving Wednesday always is, it could adversely affect road travel even though any accumulations will be light to non-existent locally. Heavy snow will be a problem but over the mountains of MD, WV and Western PA. Heavy snow could make headlines over northern and northwest PA, Western NY and Western New England.
