Another day of unseasonably cold air will make many residents of the Northeast reach for their winter coats and hats on Wednesday. The cold air is the result of a large storm system over Quebec, which is producing strong northwesterly winds across the region. Most of the I-95 corridor from Washington D.C. to Boston dropped into the upper 30s early Wednesday morning.

To put the chilly air in perspective, Tuesday's high temperature in Philadelphia was 48 degrees. The last time Philadelphia failed to reach 50 degrees was back on March 26th. Temperatures across the Northeast will be a few degrees warmer on Wednesday, thanks to a few more peeks of sunshine during the afternoon hours. The major cities along Interstate 95 are expected to climb into the 50s on Wednesday.

Even warmer air is on the way, as a ridge of high pressure is forecast to move off the East Coast over the next 24 hours. This will allow for the winds to shift to the Southwest. The warm winds will allow temperatures to return to normal for Thursday and Friday.
