Anchorage broke a daily temperature record on Monday, hitting a balmy 54 degrees mid-afternoon.
The “Pineapple Express” phenomenon has also led to unseasonably warm weather in a broad swath of Southwest and Western Alaska and could lead to a rare Anchorage snowsuit-free Halloween.
Anchorage broke a daily temperature record on Monday, hitting a balmy 54 degrees mid-afternoon, according to the National Weather Service. The previous record, 52 degrees, was set in 2013.
Anchorage’s high on Monday was a full 20 degrees over the average high temperature for Oct. 28, which is 34 degrees, said NWS meteorologist Michelle McAuley.
Pineapple Express! An atmospheric river is bringing warm and moist air all the way from Hawaii to Alaska. That will bring moderate to heavy rainfall from the Alaska Peninsula to the north Gulf Coast.— NWS Anchorage (@NWSAnchorage) October 27, 2019

The coldest Oct. 28 on record in Anchorage reached just 8 degrees, in 2008.
An “atmospheric river” has been pumping warm and moist air from the tropical Pacific Ocean north, bringing record temperatures to Alaska.
The phenomenon, known as the “Pineapple Express” has also led to unseasonably warm weather in a broad swath of Southwest and Western Alaska.
Bethel, Saint Paul, Kodiak, Cold Bay and King Salmon all broke daily temperature records on Sunday, the NWS said.
The above-average temperatures should stick around through Wednesday, McAuley said.
Thursday may be the rare Anchorage snowsuit-free Halloween, with temperatures expected to cool slightly but remain in the 40s.
Meanwhile, way off in the northwest corner of the USA, Alaska has an atmospheric river ("pineapple express" or "firehose") aimed at it. Maybe Alaska should send it to CA after it gets its fill? Just a thought. ?#AKwx pic.twitter.com/Q8XbBYSLD7— Divergent Weather (@divergent_wx) October 27, 2019
