It's only a freakin' 54deg F here now, SE wind 8-15mph, windchill ~47deg F. BRRRR... Low overnight was a frigid 40deg F.
But it'll be back to 75-78 by Friday-Tue, 80's next week?
Not to make light of that terrible weather up there that so many are suffering from.
Y'all keep in mind that even more places on Earth are experiencing much warmer than normal conditions, like Australia, the US West Coast, even down here in S TX.
[I think the coldest I ever experienced was ~ -20-25 while hunting near Ann Arbor, MI many decades ago. That was cold, was working deep nights in downtown AA and my truck's tires would be flatspotted in the mornings (~ -10-15F).]
A prominent scientist, Jennifer Francis*, explains some of it all here, in a few articles:
