Rain is falling across the Northeast on Thursday morning, setting up what's bound to be a soggy Thanksgiving for dozens of states. The forecast for both the New York and Philadelphia's Thanksgiving parades are on track for periods of rain and drizzle with temperatures in the 40s and a chilly breeze at 10-25 mph.

A storm that was pounding California's Sierra Nevada with snow Tuesday took aim at the Colorado Rockies and could roll east and slam the Appalachians on Thanksgiving Day, bringing unsettled travel weather to millions of Americans hitting the skies and roads for the holiday weekend.

Dozens of flights have been cancelled and roads have been closed in travel chaos due to a lake effect during the Thanksgiving Holiday.
