Wow thanks for posting this. I knew it was cold but didn't realize the impressive nature of it.

@bluewave frequently mentions that cold anamolies are short in duration. This is the opposite. January 15 - February 4 is the coldest 3 weeks of the year on avg to begin with. 2026 now ranks 3rd coldest for that 3 week stretch at Detroit in 153 years of record. Only 1918 & 1963 were colder.

Pittsburgh also ranks 3rd in 152 years of record. Cleveland 4th in 156 years. Toledo 6th in 153 years. And even NYC 17th in 158 years.

Anthony,

 It’s important to be aware that the WxBell Euro EW 2m maps have a notable 2m temp cold bias as I’ve posted about repeatedly. I have an easy way to show this by posting the in-house Euro weeklies maps covering the same period and comparing to this WB map.

Examples:

 -The Rockies and west coast are a very cold -3F to -10F for 2/21-3/22 on your map. What?!?
 
 -Chicago/OH Valley are -2F, Asheville is -3F, Detroit is -4F, DC/Richmond are -3F, ATL/CLT are -1F.

 -Now check out ECMWF’s in-house maps for the truth: no BN on any maps covering the same period for the locations I listed

2/23-3/1:

 

3/2-8:

 

3/9-15:

 

3/16-22:

 So based on the truth, the Rockies and much of the West should be a bit AN instead of well BN. So, that means they’re mainly 5F to 10F too cold on WB!

 The E cities I listed should be NN in Chic, Det, Ohio Valley, DC, Richmond, and +1F in ATL/CLT/ASH. So, that means these locations are 2-4F too cold on WB.

 WxBell has NYC at -4F. The truth is that they should be -1F. So, NYC is 3F too cold on WB.

@donsutherland1this remains a problem

Just for the northern MA and Northeast, thats a decent look for BN temps, albeit slightly.

Unfortunately those 10 or so days were not all that fun for here. Eastern NC though I'm sure was just in love with this pattern lol.

From the looks of the Nina phase 1 passage is taking place this weekend. Large cold dump with warming through much of the plains showing up. Going forward it does show cold building back up into Canada to be unleashed again at some point maybe the last week or so of February into early March as we move into Phase 2/3?

Hopefully phase 3 occurrs by 1st week of March (considering lag).

dt says next couple of weeks going to be bad if you want snow in the east

 

He also pointed out how off the forecast was for the MJO. It’s definitely going in the wrong direction so here is to hoping if is off about that.
