It is winter time after all.
Yes, but the odd thing.
Or perhaps better put - the unusual thing - is that the cold spell spanned the entire northern hemisphere. It’s suddenly a lot warmer here in Norway too today. -4 degrees after going through a month long spell of -20 or so (celsius).
This though does happen, but apparently we have to go back to the fifties to find when this particular weather phenomenon (arctic oscillation) was as strongly negative as it was this winter.
Anyhow.
Have a good one in Maryland :-)
