Winter Outlook Leading Factors

The Earth Networks Winter Outlook meteorology team said there are three main drivers of this year’s winter weather forecast. Here’s what they are and how much they factored into their forecast:

  1. El Niño-Southern Oscillation (ENSO) 40%
  2. Best Matched Winters (Analog Years) 30% 
  3. Decadal Trends (Temperature & Precipitation) 30% 

 

ENSO

What is ENSO?

Have you ever heard a meteorologist say the term “ENSO,” or the phrase “El Niño Southern Oscillation,” and wonder what they were talking about?

ENSO is periodic, cyclical warming or cooling of the equator With all the crazy weather. El Niño is the warming cycle and La Niña is the cooling cycle.

What does ENSO have to do with the Winter Outlook?

It all has to do with the temperatures. We know winter gets cold, but how cold it gets has a lot to do with what phase of El Niño we’re in.

Will it be an El Niño, La Niña, or Neutral winter?

This winter our meteorologists are expecting the La Niña we’re currently in to continue throughout the winter. This means the equatorial sea surface temperatures will be below average.

La Niña Winters

You can expect three main things when you have a La Niña winter.

1. From the Northwest to the Upper Mississippi Valley, you can expect a wet and cooler winter. Precipitation, especially in the mountains, will consist of snow.

2. The second thing you can expect is dry and warm weather for much of the South. If you take a look at the map above, you’ll see that La Niña winter’s typically bring the warmer weather from Texas through the East Coast.

3. The third and final thing you can expect from a La Niña is wetter weather in the Ohio Valley area.

Average snowfall patterns for La Nina years

La Niña also impacts a winter season’s precipitation.

Regions including the Northwest, northern Rockies, and Upper Mississippi River to interior New England will most likely see more snow that average during winter 2020-21.

On the over hand, the southern Rockies, Southwest mountains, Ohio Valley, and Mid-Atlantic will see less snow than average this winter.

Analog Years

Which years most closely resemble our 2020-21 Winter Outlook? There three analog years our meteorologists used to create this outlook:

  • 2005-06
  • 2007-08
  • 2010-11

Decadal Trends

In our webinar, we looked at data from the last 10 winters across the U.S. to help us get a better idea of what this winter might look like.  As you can see from the Temperature Department from Average map below, most areas in the U.S. have been warmer than normal throughout the winter months.

Decadal trends temperature department

There is more variety in terms of precipitation, with California and the South seeing less precipitation while the Northwest and Mississippi Valley saw more winter precipitation.

2020-21 Earth Networks Winter Outlook Precipitation Forecast

Northern Tier

An active northern tier storm track will produce below-average temperatures. Severe cold blasts will be far and few between. Upstate New York and interior New England will see more snow than average.

Southern Tier

The Southern tier will stay warmer than average due to active storm track staying far north. Daytime highs will likely be warmer than average on many occasions due to lack of cloud cover. The Southern Tier and Interstate 95 corridor will see a drier than average winter.

Central

We’ll see near average temperatures from the interior Northwest into the central Plains, Midwest, Ohio Valley and Great Lakes. There will be an active storm track in the Ohio and Tennessee valleys and Great Lakes. We’ll also see less snow than average for the Ohio Valley but near to above average snow likely for the Great Lakes.

The West

Drought will intensify across California, the Four Corners, Southwest and southern Rockies. Wildfire danger will be significant during any Santa Ana wind events. We expect more snow than average expected for the Cascades, northern Rockies, northern Plains and Minnesota Arrowhead. The Northwest Coast will see more rain than average.
