BOSTON (CBS) – Historic, dangerous, bone-rattling cold.

Not what you want to hear the day after a blizzard. We don’t get a whole lot of cold temperature records these days, more often than not, when we break records in the last few years/decades, it is of the warm variety. Perhaps that makes what has been happening and what is about to happen even more dramatic.

Sure, we get a period or two each winter that can be pretty harsh, we may even throw the records on the TV screen just on the off-chance we may approach them. But it’s safe to say we haven’t experienced anything as prolonged and frigid as this in a VERY long time.

How long you ask? Well we’ve been doing a lot of digging and the closest thing we could find was way back in 1917-1918 (for a stretch this prolonged and this cold). And we are now outlasting even that old streak!

If you simply take just the consecutive days below 32 degrees in Boston, Friday makes 11 in a row. No doubt we will be well below 32 both Saturday and Sunday in Boston, so that will get us up to 13 days. This will tie us for the fourth longest streak of days below 32 degrees in recorded Boston history!

As cold as it has been, this weekend will be even colder. This is rock bottom.

Looking for some good news?

Next week is looking much more “average” with highs in the 30’s and perhaps 40’s by the end of the week!

And looking longer term, it appears as though a prolonged January thaw is likely for the mid-to-latter half of January!

There is a light at the end of the cold, dark tunnel.

  1. Normal, the more the Earth will warm up more thermal shocks will be important, no offense to Mr. Trump who knows nothing about thermodynamics! Here we have a cold bubble because on the rest of the northern hemisphere it is too hot principle of the refrigerator. In Europe we are at + 15 ° C that the normal seasonal.
