2017-18 Winter Discussion Thread (Northern Hemisphere)

Feels weird to have temps in the teens during the middle of the day, when in 2015 we didn't even maded frost in December

Would be a heatwave for your dream climate though, right? lol

Wind chill advisories and warnings in effect in a good chunk of the country, from the Midwest and Northeast to the Deep South. Hard Freeze Warnings down to the Gulf coast. Even McAllen, Texas won't be avoiding chilly weather:

Very cold in Northeastern Montana, some spots nearly at -40C

Chilly morning here -9C/-10C in the city. It's pretty bizarre to have highs in the teens at any point of year in NYC, that usually means at least -20F anomalies

If you told me this is forecast for Fairbanks, Alaska, I'd probably believe you. it'd probably be plausible (albeit above average for them but quite possible). But, in fact, it's mine:

Looks like even Florida won't escape the cold hitting the eastern part of the continent late week.

meanwhile late sea ice build up in Arctic Alaska

silly cold. what an extreme tongue shape, thinks that's common with the most extreme cold outbreaks, when it's that narrow often short-lived. -28°C 850 hPa temperatures. Also not much of a ridge along the west coast, center of warmth has moved eastward over the Mountain West.
