U were 14f colder! 
 

6 for a low here 

Perfect conditions for it. You'll see in the NW thread I post a screenshot that includes Legoland, 7 miles away as the crow flies, almost 19 degree difference. I thought I might have beat KMGJ for once but they got to -9 in between hours. When I was at -8 KMGJ was around 0. Cool stuff, only 2 miles away.

Impressive low temperatures as of 7:15 am in the area around Sussex County. That -37 F in Hackettstown must be an error.

Got down to 11 here. Fri night I think has a chance to get down to 0 (not in the city).

Lake Erie is about 95% ice covered.

Very nice snow extent comeback for North America.

The RNA would be helpful here j would think. Don mentioned that as we go through February and RNA is actually beneficial.

I think 1st half is cold/dry though def not snow free but second half gets a lot more active with that blocking pattern + RNA

I encountered ice fog last night driving through Florida/warwick area. Current temp at the time was 9. It came out of no where & couldn’t see more than 2 feet in front of me. Impressive

Low of 2 in Sparta.
Lots of variability in the lows.  
Walpack bottomed out at -17!  They might do better than that in the next couple of nights.

Great video of the ice flows in the Hudson River.

Yes, during the second half of February, PNA- is better for significant or major snowfalls due to the shortening of wave lengths.

Thanks Don! With the apparent blocking and the +PNA duration this may line up perfectly.
