Mild winter could be in store for many Americans, NOAA says

WASHINGTON — A mild winter could be in store for much of the United States, according to the seasonal forecast released Thursday by the National Oceanic and Atmospheric Administration.

States from the Pacific Northwest through the northern Plains and into the Northeast are likely to see above-average temperatures, NOAA’s Climate Prediction Center reported.

No parts of the country are due to see a colder-than-normal winter.

Meantime, drier-than-average conditions are expected for the Great Lakes and portions of the northern Rockies and the northern Plains.

Those factors could mean less snow from the Intermountain West to the Midwest, where lake-effect-snow season is right around the corner.

Even so, it’s no time to ditch the shovels and heavy winter jackets, with NOAA warning that its forecast does not mean the winter of 2018-2019 will not feature major snowstorms.

“Even during a warmer-than-average winter, periods of cold temperatures and snowfall are still likely to occur,” the agency said in its outlook.

Precipitation is expected to be above normal across the southern tier of the U.S., extending up into the Mid-Atlantic.

With the Southeast the only region not projected to have above-normal temperatures, that could mean a few winter storms will bring snow to the Deep South, which can cause major disruption to the region.

The winter forecast only covers December through February, though winter weather can last well beyond that.

In March, the Northeast got clobbered by four nor’easters that brought extreme snowfalls, damaging winds and record water levels because of storm surge.

The winter forecast hinges largely on the 75 percent chance that an El Nino event — characterized by warming waters in the eastern Pacific Ocean — develops in the coming months and lasts through the season, which for meteorologists begins Dec. 1, according to NOAA.

“We expect El Nino to be in place in late fall to early winter,” said Mike Halpert, deputy director of NOAA’s Climate Prediction Center.

That could “influence the winter season by bringing wetter conditions across the southern United States, and warmer, drier conditions to parts of the North.”

El Nino tends to generate an active subtropical jet stream that would hike precipitation across the southern half of the country, including in Southern California, where beneficial rains could swiftly morph into threatening flooding and mudslides.

NOAA’s winter forecast comes as temperatures finally begin to dip across most of the country after a summer that lasted well into October in the eastern U.S., with temperatures into the 80s and even 90s.

A blast of colder temperatures also coincided with flooding rainfall this week in Texas.

Monday’s high temperature of 49 degrees in Dallas was the earliest date on record with a high temperature below 50 degrees.
