The unusual heat wave is expected to continue through the next week with highs about 15 to 20 degrees above average and comes as a massive heat dome has parked over the region.

Alaska hit record-breaking temperatures on Independence Day, shattering the previous heat record by 5 degrees.

At 5 p.m. local time Thursday, Anchorage reached 90 degrees for the first time in the state’s recorded history, topping the previous record set at Anchorage International Airport of 85 degrees on June 14, 1969.

“Breaking an all-time record by this much is pretty unheard of in the climate community,” NBC News meteorologist Bill Karins said. At least three other cities and towns in Alaska also reached new record temperatures, according to Karins.

“A plethora of daily and all-time records were set across southcentral and southwestern Alaska” on Thursday, the National Weather Service said Friday.

The northernmost state's hot spell also comes on the heels of a heat wave that baked Western Europe and shattered records in France, Germany, Poland and the Czech Republic.
