A storm pounding California’s Sierra Nevada mountains with snow Tuesday was taking aim at the Colorado Rockies and could roll east and slam the Appalachians on Thanksgiving Day, bringing unsettling travel weather to millions of Americans hitting the skies and roads for the holiday weekend.
Denver, a major travel hub, will likely see only a couple inches of snow Wednesday, but it could be enough to delay flights and slow travel along Interstate 25, 70 and 80, AccuWeather warns. Then the storm will head east. Factors that could impact the precise track and type of precipitation were still playing out Tuesday, AccuWeather Meteorologist Bernie Rayno said.
“Track and intensity (will be) the keys to where the rain and snow line will set up and the amount of snow that will fall in the Midwest and Northeast,” Rayno said.
No matter how the storm plays out, rain and snow could cause significant disruptions for tens of millions travelers, he said.
Developments:
∎ Cold temperatures could add to the havoc. By Saturday morning, about196 million Americans will be waking up to below-freezing temperatures, according to Weather.com.
∎ Overall, temperatures by the weekend in many locations will be more typical of mid-January, the National Weather Service.
