Live Blog: Flight Delays in Excess of Three Hours Stall Thanksgiving Travelers

A storm with rain and heavy snow is stretching across the East Coast and Appalachians, threatening to cause major air and roadway disruptions on the busiest travel day of the year.

While the heaviest snow will fall well north and west of the I-95 cities from Philadelphia to Boston, enough snow and sleet can fall to make roads in the cities and suburbs slushy and slippery.

Ahead of the snow, enough rain, low clouds and fog will occur to lead to airline and highway delays.

As the storm progresses, blowing and drifting snow will become problematic in areas with the heaviest totals, particularly in northern and western New England.

UPDATES: (All times listed in EST)

7:08 a.m. EST Wednesday: While rain is falling along the I-95 corridor, snowflakes are being seen across the higher terrain of West Virginia and southern Pennsylvania, according to Meteorologist Eric Leister.
