It's one of those things where we're certainly not breaking any all time or monthly records, but the duration of the cold is legitimate.
1961 was a big one.
It is a fantastic site. Thanks for sharing a week or two ago.
An effort at simplifying language by the NWS, right? Despite what Kev says the wind chill has been a thing for decades. I think it's more that we've had so many warmer than normal and outright blowtorch winters that the general public, which does not care about the weather in the way us weenies do, forgot what normal cold actually is around here. This one is extended to be sure, but the point still stands.
