everything he “models” is long range so my money is on teleconnections a la beiring sea rule or lezak recurring cycle or an “all blend” of both making “Brian’s proprietary model” copyright 2021

 

ps no diss Brian, while your maps are vague with farmers almanac levels of leaving yourself open to being accurate no matter what happens you have had some ringer level hits this season

 

That was my initial impression as well, mentioned them in one of the other threads as well.

 

I think there is a little credence to all of them in their own rite, but to call a theory a model is a bit much. I'll end it at that as I've come to acknowledge they're(other theories) not well received here for scientific purposes. No issue with that either, I just love to be prepared for what lies ahead regardless the means, and morseo use the greater knowledge of everyone involved to keep friends and family safe days in advance.

 

For all I know he was Musk or Bezos and had supercomputers with an alias to keep it on the downlow :lol:

With all the snow just north of me, it looks like I'll be going into this cold snap with close to no snow on the ground.

I wonder how hard it would be to find the lowest recorded temperature with <1" of snow on the ground at a given observing site. :nerdsmiley:

February 1996 redux incoming!

 I believe hoosier has posted stats before, and it's way more common than you would think to have no snow or just a trace on the ground with temperatures below 0, especially away from the Great Lakes.

The mammoth artic blast Christmas December '83 is an excellent example, in SE Ohio in Athens Co we went below zero for 3 days down to -13F w/o a flake of snow, then 2 days later the very next spec of precip was.....    ....wait for it, ....rain! :angry:

I edited the title to change the dates to Feb 7-12, as there is growing consensus of a prolonged cold snap.  IMO, how extreme on any given day is still TBD. 

6z GFS still shows significant cold temps here...and that's even before the true cold drops down around Days 7-9.  Seems like more of a radiator set-up overall, where nights are extremely cold but it warms up (relatively speaking) during the day because the airmass itself is not brutal...though still colder than normal.  It's like the freezer keep regenerating, with all of the snow cover and consistent high pressure in a colder-than-normal airmass.  It shows 8 consecutive days of subzero low temps here, with some days not getting much above 0...not easy to do this time of year.  Really an amazing GFS run for prolonged arctic cold, verbatim...noting the usual op run caveats further out in time.

Shouldn't you edit the dates to Feb 5-12 ? I think the arctic air arrives in some areas on the 5th ?

doesn’t meet beavis criteria.

Ha.  Now that there is extensive snow cover, I'd rather put all of our chips in on the cold.  But if the choices are "cold with snow" or "extreme cold with not as much snow"...can't go wrong wither way. :snowman:

Nice 1060 high in MT at Day 8-9 on the 12z GFS; the Euro showed something similar yesterday.  I'm sure there are maps showing this data...but I don't think the lower 48 has ever had a pressure this high in February in recorded history.  Fun times ahead...

Correct! Looks like it's 1058.5 mb

Can you post some more about your model? What is it and how do you ingest data and such? Couldn't imagine the specs of a computer to accomplish such a feat at home. I recall Skilling used to state he had an inhouse RPM model, similar?

 

I've been a lurker during my first umpteen years here and have not followed along with every system thread since then, until this year(Winter season). May have missed it, but I'm curious whether to add more weight to your postings or if it is a bit of BS.

 

Not calling you out on it, just want a bit more info if you could.

I don't get into my methods. I keep that close. I'm not trying to BS anyone, just having fun with this hobby. Have been doing it off and on over the years. I don't charge anything for forecasts like some out there do. I try to be honest and if I blow it, I own up to it. Whatever you wish to think about what I do, or how good or bad I am at it, I'll leave up to you. 

Thanks for your interest, and if the forum wishes me to stop doing this, I'll respect their wishes.

This map is probably overdone with the cold...but I think it's reasonable to expect some -10 to -15 temps in N IL on Sunday morning 2/7.  Chicago's record low is -10 set in 1875...could be threatened.  Rockford's record low is -16 set in 1972...that could be in jeopardy too. And some nice -52F temps in N Manitoba. :wub:

No worries man, up until your 3rd-5th thread and seeing you mention it in a post on this thread I haven't seen your other predictions and how they have panned out.

 

You said "your model" so I figured you had somehow delved a way to incorporate an algorythm/program to actually forecast. We never know who we are really interacting with on the internet, you could have the wealth of Bezos for all I know and have your own weather predictor :lol:

 

I like your terminology in this post a lot better in using "method" rather than model, in weather forecasting the difference in definition is vastly different.

 

Good luck with it, and if it works it works. If not, try and try again.
