Some of the pits further west decoupled. 

Mins through 12z

Still can’t believe Worcester schools closed

Actually below zero now. Must have been a late secondary arctic surge . We’ll see what it bottoms out at

Don't worry. They're all at @weatherwiz house.

Actually I've seen very few myself. Maybe a few. 

For my birthday my girlfriend got me this little device thing where you like put it over the spider and then slowly move a notch and it traps it so you can put it outside. It actually works kind of well but I told her I can only deal with that up to a certain size. 

I think there has only been one in the bathroom and I caught one crawling on the floor when I was cleaning. Other than that, nothing else.

8° at KBOS this morning, WC -11°. With the sun angle it didn't even feel that bad. (I think a lot of it is that we're kind of getting used to it.)

Today is 6 days at BOS <30°. 9 is likely by Sunday, which would be tied for 11th longest. 

The record at or below 32° is 16 days. Neither the Euro or GFS has BOS breaking 32 through the end of the model, which if it verified would break that record by a lot.

(Thanks goodness we got that storm last week or we'd have cold, mostly-brown conditions which would be miserable.)

Very meh as far as low temps today compared with other days/locations.  A bit breezy.

[CT Valley Snowman]

If I go calm tonight I'm thinking double digits below zero.

Think we see alot of those tonight for the radiators. Looks fairly calm and clear for interior SNE/CNE.

CEF was -15 yesterday.  All time record low is -22 from 2018 and 1961.  Doubt we get there but another -15 seems in play or even a bit colder.

Dang.  I have to wonder what ORH was at that time, because CEF kind of sucks except for fake cold.  Like today's low was 3.

[wx2fish]

One thing ive noticed this week is the AIFS has been horrible with rad cooling over the snowpack. Its a little surprising, given it generally outperforms with regards to temps. But, something is off with a deep snowpack.

This morning it was close, but Tuesday and wedneday mornings it was off 10+ across alot of the interior. All models can struggle with it, but the euro op was alot closer. I suppose it could be a resolution issue.

-15.5/-37.5 26kt is pretty good. There’s not a lot of hourlies available from back then though.

BED had -22 the following morning with radiating

Looks like that is the all time record low for ORH? Must have been some serious fake cold to put up a 24/-24 on the day  

2/9/1934 only other sub -20 min on record and 2/-20 on the day

I think 43 may be the coldest airmass on record for up here…afternoon high on 2/15 was -7 at CEF

CON and PWM had all time record lows of -37 and -39. But yeah, there was some rad cooling the morning of the 16th with WAA all day. CEF only had a high of 15° in the hourlies for 2/16 though so I can’t really comment on that ORH 24°.

[ORH_wxman]

ORH back then was a coop so it kind of sucks....the hourly airport obs didnt start until 1947 I don't think and it didn't go official until 1948.
