Experts: Expect Continued High Arctic And Sub-Arctic Temperatures Through October
The Arctic has been gripped in extraordinary warmth since December, when an Atlantic storm blew in from the south and pushed temperatures near the North Pole to about the point of thaw. Expect that unusual warmth to continue, at least in the short term, experts advise.
Temperatures in eastern Siberia and parts of Alaska could reach above 80 degrees in coming days, according to the University of Maine's Climate Reanalyzer. Temperatures are likely to be above normal in all of Alaska this June and all the way through October, according to the National Weather Service's Climate Prediction Center. Most of Canada is also likely to have higher-than-normal temperatures, at least through fall, according to Environment Canada's seasonal forecasts.
That fits with a trend, mapped out by Andrew Slater of the National Snow and Ice Data Center, of unusual warmth for the high Arctic that has run for the entire year to date. "It has been an outlier year," Slater said.
He identified four "notable zones" of unusual warmth in the Arctic and circumpolar north the central Arctic, which was warmed up by the December storm; the Barents and Kara seas, where lack of winter ice allowed heat and moisture to stream into the atmosphere; southwestern Alaska, where ice was especially low in the Bering Sea; and the land areas of Siberia.
