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.

There are currently no major storms forecast for the near future, but rain, wind and snow could snarl travel plans for Americans headed to the airport for the Thanksgiving holiday. Here's where travelers could see delays at major travel hubs, according to the Weather Channel:

One of the strongest storms we've seen in Massachusetts in quite a while will bring rain and snow on Thanksgiving.

Central Minnesota and western Wisconsin could see a dusting of snow Wednesday as a weak system moves across the region, but snow is not expected in the Twin Cities.

Tens of millions will travel during the holiday period, and weather could interrupt plans for some. Here's a look at the forecast.
