The Steese Highway was closed in the same area on the 3rd, while a travel advisory was issued for the Dalton Highway on the 5th due to high winds and being impassable along the northern end of the road.

Snowfall totals for the Southcentral areas on the 16th were 8" at Portage and Hatcher Pass and 8" at Thompson Pass, while parts of Anchorage received 4" to 5". The next day, high winds and drifting snow made for difficult travel along parts of the Parks and Richardson Highways.

Extreme cold began to descend across much of the State on the 17th with a temperature range of 101°F from -51°F at McGrath and Tanana to +50°F at Annette. Anchorage Airport hit -15°F on the 18th, and this was the first time in five years this cold of a temperature had been reported. Barrow reported -30°F, and this ended the longest streak of 387 days, on record, of temperatures staying above this mark. Previous record had been 369 days ending on January 20th, 2006. Temperatures dropped lower on the 18th with - 51°F reported at Fairbanks Airport, the first time for that temperature in six years, and it has not been colder than -51°F since the -52°F on New Year's Eve 1999. In the Fairbanks area, -59°F was reported near the Salcha River, -52°F at Eielson and -51°F at Ft Wainwright. Tanana also reported -59°F and Bettles reported -56°F. The next day Tanana and Bettles reported a low of -53°F. In the Southcentral area temperatures were: -38°F at Talkeetna, -33°F at Wasilla, -20°F at Palmer and -29°F at Kenai. Elliot Highway reported hazardous driving conditions on the 20th. The next day the sun rose at Barrow for the first time in over 2 months.

On the 21st, heavy snowfall impacted the Southcentral areas resulting in avalanche warnings being issued for the south and western Kenai Mountains, and hazardous driving conditions reported along the Seward Highway due to snow and high winds up to 50 mph. Moose Pass reported snowfall totals of over 2 feet. The heavy snowfall prompted the city of Seward to declare a local emergency and request aid from the State as more than 2 ½ feet of snow had fallen in the city. An immediate financial help was provided by local government, AlaskaUSA, Alaska National Insurance, and Guaranteed Emergency Loans. The snowstorm gave Anchorage a winter total of 44.3", more than the previous two winters combined, and resulted in a number of vehicle accidents and the collapse of the dome roof of a sports facility. Two days later avalanche reduction efforts were instituted from miles 19 to 45 along the Seward Highway, and this was repeated for miles 80 to 100 on the 26th. Freezing rain in Anchorage on the 26th generated a number of vehicle accidents and the closure of all after school activities. More avalanche warnings were issued on the 26th for the Kenai Mountains and Turnagain Pass.

As warmer temperatures pushed across the State, Eielson AFB reported a high of +36°F on the 26th, 89°F warmer than the -53°F from the previous week. Denali Park reported 43°F on the 26th, with winds up to 60 mph through the passes of the Alaska Range. The warming created ice roads along the Elliott Highway and drivers were warned to avoid the road.

More high winds along the Panhandle on the 27th resulted in observations of 84 mph at Cape Decision, 77 mph at Hydaburg, 67 mph at Ketchikan, 62 mph at Sitka and Juneau, and 60 mph at Yakutat. The next day winds topped out at 71 mph at Cape Fairweather, 64 mph at Lincoln Island, 58 mph at Annette, 55 mph at Juneau, and 52 mph at Ketchikan and Yakutat. More snow in the Southcentral area on the 38th totaled up to 8" at Wasilla, 7" at Eagle River and up to 6" around Anchorage. Total January snowfall at sea level at Alyeska was over 56". Toward the end of the month, avalanche reduction efforts were conducted along the Dalton Highway in the Brooks Range.
