Minimum 12-Day Mean Min Temperature for Alaska Records (From NOAA RCC S Xmacis2)
Jan. 1989 Cold Snap
For about two weeks, extreme cold gripped most of Alaska. The cold snap was caused by a reduction of warm air advection resulting from a southward-shifted jet stream. This prevented low-pressure systems to move in and warm the Interior, thus high pressures built and temperatures plummeted.[1] The worst of the cold snap, occurring during the end of January, was exacerbated by cold-air advection near the surface from Siberia.[2]
A variety of consequences strained Alaskans because of the cold snap. The troubles included: fuel shortages, congealed heating fuel, cars not being able to start, scattered telephone outages, frozen water and sewage lines, and non-delivery of supplies to villages. Governor Cowper signed a declaration of emergency to have more funds readily available for the emergencies.[3]
Many single-day and multi-day records were set during these two weeks. On January 31 in Northway, the pressure rose to 31.85inHg, which became the highest North American pressure ever recorded, until the record was broken two days later in Dawson City, Yukon.[4] The coldest temperature during this time was -76F in Tanana, followed by -75F in McGrath[5], but temperatures of -50F to -60F were common, with wind chills in the -100Fs.
The high finally began moving eastward on February 1, plaguing Canada and the lower 48.[6] Contrastingly, Alaska had an anomalously warm February because of warm advection due to strong meridional flow.1 On February 5, a Fairbanks sounding recorded the station’s largest ever surface-to-925mb temperature inversion of nearly 60F as temperatures began to rise.[7]
