Polar vortex to blast US with freezing temperatures: ‘There’s no escaping this’

Most of the US will enjoy milder temperatures on Thursday, but the warmup will be brief as a polar vortex will send temperatures tumbling below freezing for most of the nation starting this weekend.

Despite a cold start across parts of the eastern US on Thursday, most of the country will experience milder temperatures with forecast highs as much as 20 degrees above average. Enjoy it while it lasts, however, because it’s about to get brutally cold.

How cold?

Minneapolis has a forecast high temperature of about 34 degrees on Thursday. On Sunday, the forecast high temperature is a frigid 3 degrees below zero.
In fact, more than 300 million Americans will experience below-average temperatures by Monday.

The FOX Forecast Center said temperatures will plummet as much as 45 degrees below average in spots, leading to below-zero temperatures across at least 20 states, from the Plains to the Great Lakes and interior Northeast.
All the lower 48 states and more than 80% of the population will see temperatures drop below freezing. The deep chill will be felt as far as the Deep South, with only South Florida escaping the icy grip of the arctic blast.

Polar vortex to blast US with freezing temperatures: ‘There’s no escaping this’

“Perfect time to hop on a plane and go somewhere south,” FOX Weather Meteorologist Britta Merwin said. “Like, really, really far south.”

And up where polar vortexes belong, in the Yukon, my step mum and step sister have had above freezing in the daytime last week out at the cabin on Lake LaBarge. The snow is melting.

I guess I won't be walking outdoors for the next few days. Then we escape to EL Paso where it might be cold for El Paso but will be warm for us.

Maryland will be unusually cold starting on Monday and into next week. We are one of those states that can go either way in the winter, it can be in the 50s all season or freezing cold.

It's not good when the southern areas get hit because pipes aren't as well insulated or dug as deep into the ground as they have to be up north where it's routine. People get those awful ice storms, and I can't imagine the chaos.

Just to make everyone feel better . . .

International Falls, MN, predicted high on Monday is -15F without the windchill

Also the insulation in many houses in America sucks. In most of Canada all new construction requires R-50 in the attic and at least R-24 in the exterior walls. Here in Illinois, I believe the required value for attics is currently R-24 with R-13 in exterior walls. The best I've been able to find out is that when the apartment building we live in was built in the 1970s, the exterior wall requirement was R-13 and the attic requirement was R-16. We freeze here unless we crank the heat right up and keep it running on really could days..

R49 for ceilings here, and cathedral ceilings have some reduction. It's been that way since I was a kid when Parents built summer house, so I learned about building codes, etc.

Walls suck . . . R20 or 13+5. They should be R40 or better

If I ever get to build, I want R64 in the ceiling, R50 in the walls, and R31 in the interior walls. Insulation in the interior walls helps with heating and cooling AND sound-proofing. Good insulation helps keep energy costs down all year-round. Can't go too overboard, though, because too tight an envelope means the building can't breathe or move/give, which creates big problems.

For a little extra cost when building, you get savings and comfort for the entire life of the structure. I've never understood why better insulation isn't included in new developments everywhere in the country nowadays. The Alaska home I had built was super-insulated. Even at minus 20 deg F the boiler in the Alaska home wouldn't run as often as the gas furnace here runs when it's 30 deg F...

'Life-threatening' cold weather to expand southward across the nation​

The coldest air so far this winter will plague the Central and East once again this week, plunging temperatures below zero for an extended period of time for some cities.

“The cold air will have wide-reaching impacts on everyday life and the economy, such as stressed power grids due to increased heating demands, closed schools, health impacts and dangerous AccuWeather RealFeel® Temperatures as low as minus 50 degrees Fahrenheit,” explained AccuWeather Meteorologist Haley Taylor.

The core of the cold is on track to arrive by Monday and Monday night across portions of the Dakotas, Minnesota and Wisconsin. Actual daytime temperatures on Monday will not even crest the 0-degree mark across these regions, while overnight temperatures are projected to drop as low as 20 to 30 degrees below zero.

@Ghoti Ichthus

Cities like Minneapolis are among some locations projected to be at or below the 0-degree mark for an extended period of time, currently forecast to be subzero from Saturday night to Monday morning. This extended period will place a strain on the energy supply with residents trying to keep their homes and businesses warm enough.

Man made global warming is certainly showing itself at the moment... I'm gonna try and escape to El Paso where the temps are in the balmy 40s and 50s.

That's why I believe TPTB created this new "feels like" temperature/new windchill. Make winters seem less cold on paper or news/weather forecast, thereby "raising" temps and "proving" global warming.

Um, nope. Not going to drink that koolaid.

R-13 is 2 X 4 studs. Next size up is 2 X 6 which gives R-18. After that the walls are built to give the R rating that is desired. But once past the 6" walls then go for desired insulation. Then it is just the extra cost for the insulation.
