Yeah let’s get that to move SW.

I'm also looking at the indies and it looks like if we get that block, there most likely won't be SE ridge issues. the vast majority of members with a SE ridge are the ones that keep the block over Iceland or don't develop it at all

 

At least this is forming in a classic manner…when we get big UK/Scandi ridge retrograding into an NAO block, it is more believable than other evolutions. Sometimes we’ll get duped by shallower wave-breaking events in the North Atlantic or Labrador and they seem to fall apart easier in guidance. 
 

Hopefully this one is real.

only a couple members with the blocking truly link it with a SE ridge

That would help push the ridge response to the SW too. It may not lead to a big +PNA but enough to kick the deep -PNA in it’s face.

i mean... this is kinda sorta how that December block formed. same kinda Scandi retrograding block, and it got picked up around the same time

I agree with you in that this is how you'd want to see a block evolve. it's certainly more reliable than the shitty wave-break stuff. the SSW also bolsters the case for it

Sleet/freezing rain for hours?

Oh f@@k that.

Snow or no.

I’d take it if we can get 3 or 4 inches on the front end. Then sleet and ZR on top to solidify the pack for the next threats….I’d like a couple weeks of wintry appeal at least if we’re not gonna be able to cook up a big dog.

Depends on a number of factors, timing, amounts, ect, but in general that type of storm causes many more headaches than it's worth. It would be fitting for this winter to have a kitchen sink storm though.

Is there any possibility this could be an all out icestorm for SNE? Just like a straight zr storm ? I’d almost prefer that over snow to rain 

Euro was kind of close but it was too cold in the low levels for ice. The cold layer was too thick so it would prob pound sleet at 20 degrees most of the storm. But can’t rule out an icier solution in the future.

Verbatim the euro gives us a healthy front ender, a pelting, then light snow/snizzle.  I’d take that.  Euro with a nice follow up event a few days later.  Caveat I don’t have access to euro soundings so I’m guided by H7

Nice thunderstorm this morning.  Temperature is now up to 43F.  CF shortly

I'm going to post this in the general obs thread too.

Wow, I am amazed how much colder I have been compared to places like Concord NH which is only 35 miles south of me.  Boston is 100 miles away but the climate is so much warmer down there.  I retain snow cover  well and CAD always seems to overperform.  I just realized that I have not hit 50F yet this year!  Some close calls this week but surely not the spring weather so close by.  I know there are a lot of frustrated snow lovers but a salt free roads and bare ground would be nice to see.  My acreage faces south and finally we are getting some bare ground but everyplace around me is still snow covered.  This snow is so durable.  Below if a graph of my temps so far this year.  Guess I'm going to have to wait for my first 50F!

I swear, you must have fallen on your head somewhere and never recovered fully ... lol

You mean to tell me you wouldn't care if we had an intense ice storm which would break or kill trees and bushes, bring down wires, possibly do damage to homes... 

I will send it all to your house. You can have all of that. I'll take snow and I'll take sleet.. I do not want ice

With such a negative PNA this thing has nowhere to go but north . 6 -7 days to trend 

At this time and in this setup, it is all about how the block retrogrades... if it diverts a bit southwest, colder/snowier/icier trends would win out.  One way or the other, I think the next 2 model runs will start locking on to the final outcome with regards to the block.  Not a lot of wiggle room given southeast ridge & -PNA so will need to block to make it all happen?
