Ouch. Talk about an early polar vortex. 0F in Denver last week. We didn't have many extreme hot days like we used to in the summer, & some pretty cool days because these frequent vortexes continued over the summer. But because we live so close to, & downwind from the Great Lakes, it was quite uncomfortably humid. It was like being in a steam room even on cool days, making my COPD worse. But a cooler humid day was much better than a hot humid day.
All that damp moisture coming off the lakes, is exactly what causes these "lake effect" snows when the cold winds pass over them. Take a cold bottle out of the fridge on a humid day, & water quickly condenses onto it. Take a super cold frozen container out of the freezer, & frost condenses onto it.
Once again I was too cheap to turn on my heat last night. With the computers giving off heat, heat generated by making a meal & coffee, & the heat coming off the back of the fridge, it was 65F in the house at bedtime. Went to bed in a cute pink & patterned footed sleeper. Under the blankets I felt warm all night. But it was 53F inside when I got up. Brrr, but the sleeper kept my feet warm. After making some breakfast & coffee, it already warmed up the place to 60F. The fridge kicked in, so it's blowing heat off the back, so it should get warmer within an hour. If it doesn't, I may just fire up a small radiant (reflective) electric heater pointed towards me rather than fire up the main heat.
Kitties don't seem to care about the chill at all, except when we're sleeping. They'll curl up on top of, or against me, but they'll do that even in the summer except on hot days. When it's hot they prefer hanging near the AC, or in the cool hard bathtub & bathroom sink. They like it cool.
It looks like we got another 3-4 inches in the city overnight. Not much to talk about, but at the southern edge of the city (South Buffalo), they got an additional 8-12 inches overnight. Towns south & south east of the city got 12-18 more inches of snow overnight. Portions of Lancaster, Orchard Park, Hamburg, Lackawana, & southern Checktowaga have 6-8 feet of snow on the ground (about 2 meters). But my sister, in mid-Cheektowaga only has about 1/2 a foot of snow.
The deaths from the storm so far seem to be from people getting heart attacks shoveling or running their snow blower. When it get's deep & it's a lot of snow, even with a snow blower, it can be quite a workout, especially in single digit wind chills. People try to do too much at once, or more than they should for the shape or age they are.
Be careful out there, & take your time. You don't have to deal with all of it all at once if it puts your health or life at risk. Call for help, or even pay for help. Some of your neighbors will even accept an IOU to help. Or let them use your snow blower or gasoline if they blow your place too. You can trade food for help if you're better stocked than they are.
