Arctic blast about to invade US. What happened to warm winter predictions?

Hoping for a January thaw? Dream on.

Wasn't this supposed to be a milder-than-average winter for the East and the South? Toasty isn't exactly how you will describe the bone-numbing coming days.

"Multiple waves of arctic air continue to gather over northern Canada with eyes for the central and eastern United States in the days and weeks ahead," AccuWeather meteorologist Paul Pastelok said this week.

"By Tuesday, the entire Lower 48 (will be) blasted with extreme Arctic cold. ... The first days of the new Trump administration will be heavily focused on weather-related problems," meteorologist Ryan Maue posted on X this week.

Maybe Ted Cruz needs to make another reservation to Cancun.

These make the sort of predictions rather hit and miss.

Driven, of course, by climate change and a warming planet.

Santa Ana winds over Los Angeles in January is a perfect example.

If it wasn't for sunlight and our atmosphere's ability to retain heat, we would be as cold as interplanetary space!

Interstellar space is very cold, with an average temperature of 2.7 kelvins ((-454.8degree F) or (-270.4degree C)). This is only a few degrees above absolute zero, the temperature at which molecular motion stops.

it is only objects in space. And that depends primarily on how close it is to a source of heat, such as the sun, and whether it has an internal source.

All objects in space are however subjected to the cosmic background radiation but it has an effective temperature of only about -270 C so any object not subject to star light or the equivalent would cool to about that temperature (unless it had an internal heat source).

So, no matter how cold it may seem here in winter, we are sweltering compared to what it could be!
