How does the temperature change 17C in one hour? How? We can't even get it to change 17C in one DAY let alone one hour.

Definitely looking like a thaw coming. Wash all this white stuff off my land. Bring back the green. Hope it didn’t go yellow.

Euro has been Sh*t. While I do believe there will be a warm up I think it's being overdone.

I do wish it'd clear up so we can cool down in a hurry again.

Chilly like reload chilly or 1.5C rain chilly?

Oh wait. Forget I asked. I know which one you pick.

Still light flurries here and not amounting to much anymore. I've just been sitting in my living room and staring at the street light. Something peaceful about watching snow fall.

Certainly a lot stronger with the NPAC blocking day 6+. Maybe a fast warm up but a quicker cool down?

That’s some insanely anomalous ridging moving into Alaska but we need a little more help from the northeast pacific ridge so that the energy doesn’t dig offshore
