Baked Alaska: How That Frigid Northern State Not So Frigid This Winter, Compared To The Lower 48.

The Washington Post just had an interesting piece comparing the kind of January Alaska has had compared to the rest of us in the tropical Lower 48. 

Compared to Alaska, the Lower 48 ain't so tropical.  There's quite a role reversal going on. 

Anchorage, Alaska is having one of its warmest Januaries on record. With just a few days left in the month, the average temperature for January is 29.3 degrees, or a whopping 13 or so degrees warmer than normal.

Anchorage in January has been warmer than such cities as Indianapolis, Pittsburgh, Cincinnati, St. Louis and Louisville. 

We also had that famous snowstorm along the Gulf Coast earlier this month, which means New Orleans and Pensacola, Florida have had more snow this January than Anchorage. 

It's not just Anchorage. Fairbanks, in interior Alaska, is normally known as a forbidding icebox, where low temperatures often get into the 40s below zero and sometimes in the 50s to near 60 below. 

For only the second time on record, Fairbanks had a low temperature on a January day that was above freezing. (33 on January 25). On seven days this month,  the temperature in Fairbanks rose above 32 degrees. 

The normal high during January is 3 above zero and the normal low is about 15 below.  

Meanwhile, most of the Lower 48 has been unusually cold this January. That's especially true in the southeastern half of the United States. Though that region is having a mild spell in the closing days of this month, it will still be among the colder Januaries on record in much of the South.

The only regions of the Lower 48 that have been warmer than average are Maine, and large sections of Nevada, California, Oregon and Utah. 

REASONS AND OUTLOOK

The Alaska warmth is probably a mix between a fluke and climate change. A persistent northward bulge in the jet stream has kept Alaska on the mild side. A corresponding dip in the jet stream has pushed frigid air that's normally up in Alaska and northern Canada down into the United States. 

A marine heat wave, which is a zone of much warmer than normal ocean temperatures, has been ongoing in the Pacific from near Japan to the Gulf of Alaska. The marine heat wave is likely at least partly due to climate change and has probably been bolstering the Alaska balminess.

Plus, cold waves are in general less cold than they once were and hot spells are hotter in this age of climate change. That's likely a factor that has caused record heat in Alaska.  

The cold temperatures in the Lower 48 have broken few record lows, except near the Gulf Coast, where a previously unheard of snow cover combined with clear nighttime skies caused all time record lows as cold as 1 below zero not far from the Gulf of Mexico in Louisiana. 

(Editor's note: Yes, the Trump administration has renamed it Gulf of America, but international regulators, as well as the Associated Press style book still call it the Gulf of Mexico, so that's what we'll do here). 

The Alaska winter warmth is expected to mostly continue for awhile yet. The latest National Weather Service extended forecast out to two weeks calls for continued above normal temperatures in most of Alaska at least until a tad before Valentine's Day.  

For the Lower 48, the outlook is mixed, with variable conditions over the next two weeks. The northwestern United States is most likely to stay on the chilly side. 

Theses kinds of things do have a tendency to even out, usually. Although everything is skewed by climate change, I'm sure the Lower 48 will have its torrid hot spells in 2025 while Alaska will at least at times, revert back to its usual chilly vibe
