A day after a quick-moving Nor'easter dumped a foot or more of snow on parts of the area, skies brightened Friday with the sun out in abundance.
But in the afternoon, motorists traveling near the border of Westchester and Fairfield counties saw a sight many had never seen before - rows of vertical, line-shaped clouds.
Lisa Wexler, host of a daily late-afternoon radio show on WGCH 1490AM, pulled over from the Merritt Parkway in Stamford to snap a photo (shown above) just before 3 p.m.
"I had no idea what they were," she said. "Some people said it might be chemicals."
After sharing her story -- and the photo -- with WGCH operations manager/traffic manager Bob Small shortly afterward, Wexler learned she had just contrails.
Contrails, short for condensation trails, are vapor trails sometimes produced by aircraft engine exhaust, usually at cruise altitudes several miles above the surface.
They are composed primarily of water, in the form of ice crystals.
Listeners on Wexler's show, which airs from 4 p.m. to 6 p.m., called in to say they also saw the contrails from Westchester.
