Lightning Detected within 300 Miles of North Pole Today...

A number of lightning strikes were recorded between 4pm and 6pm
today within 300 miles of the North Pole. The lightning strikes
occurred near 85 degrees north, 120 degrees east, which is about
700 miles north of the Lena River Delta of Siberia. This lightning
was detected by the GLD lightning detection network which is used
by the National Weather Service. This is one of the furthest
north lightning strikes in Alaska Forecaster memory.

There has been record warmth in and around the north pole this summer. This makes lightning much more likely at high latitudes. There's been an unusually strong and persistent blocking high pressure system just south of Alaska that's caused the northern branch of the polar jet to deviate north of the Pacific Ocean. This has meant a very warm, dry, and sunny summer for most of southern Alaska. The tendency for a trough to form downstream of the ridge near Alaska has meant more northerly flow over Canada. Persistent cooler northerly flow over Canada has meant the lack of any significant heat wave over the US this summer, outside the far southwest at least. Europe and Asia have experienced several significant heat waves this summer though. The northern hemisphere average this summer is in record warm territory, despite mostly average temperatures over North America.
