(The Washington Post) – As an antidote to the report of minus-88 degree weather in the Siberian outpost of Oymyakon earlier this month, we give you this: The temperature in a settlement just to its east was an astonishing 126 degrees warmer two weeks later.

The mercury in Omolon, Russia, reached its highest January temperature ever recorded Monday: a relatively toasty 38.4 degrees.

But the warmth flooding east Siberia and parts of the Arctic may, in turn, displace the frigid air that is normally pooled there sending it surging south into the north central and Northeastern U.S. through mid-February.

The mild weather over east Siberia can be traced to the development of an enormous, bulging zone of high pressure over eastern Russia. […] Mashable science editor Andrew Freedman called it “one heckuva monster” on Twitter

Underneath this high pressure zone, models show temperature differences from normal exceeding 50 degrees over a broad area. Weather.US meteorologist Ryan Maue tweeted that these temperature anomalies are “off the charts.”

The Arctic seas, surrounding this region, including the East Siberia, Bering, and Chukchi have historically low amounts of ice, which is likely intensifying this warm pattern. [more]

The temperature in Siberia rose 100 degrees. The northern U.S. may pay a frigid price.
