Potentially longest cold snap in more than a decade for Anchorage
For the last four nights, temperatures dropped below zero in Anchorage, which isn't uncommon this time of year, but turns out, hasn't been very common in recent history.
Even on the warm side of town, temperatures dropped to -11 degrees Monday at Ted Stevens, which is the first time since 2017 it's been that cold, but what makes this stretch of cold weather more unique than 2017 is how long it's continuing.
Back in 2017, we had 4 days below zero, including two nights down to -15 but then it quickly warmed back to normal, in the teens. Our current cold snap, however, will likely continue for several more days.
We're currently under a rather stagnant weather pattern with consistent flow out of the north, which is keeping this cold Arctic air in place across most of the state. Temperatures across the Interior this week have been between -30 and -47 degrees. Fairbanks dropped below zero New Years Day and hasn't been above since.
This cold snap will keep much of the Interior below zero both day and night for close to two weeks and will keep Anchorage below zero overnight through the end of the week.
A stretch of 8 days below zero, which is the current forecast for Anchorage, would make this the longest stretch of temperatures of -3° or lower since 2009. We've seen 8-day stretches of weather this cold more than 30 times since the 1950s, but it's only happened 4 times in the last 20 years.
Bottom line, this cold snap isn't record-setting but if it continues as forecast, it'll be the longest in more than a decade.
