WASHINGTON — If you thought last winter was a horror show, with cold blasts from the polar vortex and a lack of California rain, here’s some good news: No sequel is expected this year, federal forecasters say.
Mike Halpert of the National Oceanic and Atmospheric Administration said Thursday that the upcoming winter looks pretty average in general. He doesn’t expect a lot of extreme conditions like last year’s cold outbreaks when Arctic air dipped south with the polar vortex.
‘‘A repeat of last winter is not particularly likely,’’ said Halpert, acting director of NOAA’s Climate Prediction Center in College Park, Md.
That doesn’t mean there won’t be cold air and snow, which is normal for much of the country during winter, Halpert said. It just won’t persist as much as it did last year, he said.
Similarly, the high pressure ridge off the Pacific coast that last year kept rain out of California during its crucial winter rainy season is unlikely to return in force, Halpert said.
For December through February, NOAA forecasts warmer-than-normal winter temperatures for northern New England.
