The color of cold

I asked my grandkids this morning:  what do you think of when you imagine intense cold like we have today (-22 F at 7 a.m. this morning) ?  They said — white, blue, partially transparent — sort of like this.

Sunset 4:30 p.m. in St. Paul MN - temperature -12 F

White and blue, slightly purple colors at sunset 4:30 p.m. in St. Paul MN – temperature -12 F

Intense cold makes interesting patterns of ice crystals on the insides of our windows -- white, slightly transparent.

But weather forecasters reserve the color purple for the really intense cold.

  1. We warmed up to about 40 degrees this morning. Now, the temperatures are dropping back to the single digits later tonight/early tomorrow. But -22? I don’t think I’ve ever experienced that kind of cold!

  2. They say that a pattern change is going to happen later this week and that’s supposed to get things back to “normal.” My problem is, I’m not sure that I really know what is normal anymore when it comes to weather.
