US: Winter 20/21 Long-Range Weather Forecast

Newsroom Long Range Forecast US: Winter 20/21 Long-Range Weather Forecast

With everything going on in 2020, we’re looking forward to the 20/21 winter season now more than ever. We sat down with meteorologist Chris Tomer to get a pulse on what we can expect this season.

➽ What will the snow be like for winter 2020/2021?

La Nina will dominate this Winter’s forecast.  Last Winter El Nino was in control.  Now water temps in the south Pacific near the equator have cooled-off.  In fact, some data suggest this could be the strongest La Nina in 10 years.

What does this mean for snowfall patterns this Winter?  I’m forecasting the most consistent winter snowfall across the Pacific Northwest and northern Intermountain West.  The presence of La Nina (cooler water) tends to force the jet stream into a pattern that favors these geographic areas.

➽ Who will have the best Thanksgiving and Christmas snow?

Shoot for the Pacific Northwest, Idaho, Montana, Wyoming, northern Utah and northern Colorado.  Suggestions include Whistler/Blackcomb, Banff, Kicking Horse, Schweitzer, Sun Valley, Big Sky, Bridger Bowl, Grand Targhee, Jackson Hole, Snowbasin, Alta, Snowbird, Steamboat, Loveland, and Winter Park.

➽ Who’s on the bubble?

There are resorts too close to call.  I’m forecasting normal snowfall at Tahoe, Mammoth, Aspen/Snowmass, Crested Butte, and Monarch.  These are places where the jet stream will visit frequently but not enough to tip the scale.
