January 25/26 Jimbo Back Surgery Storm

If everyone (a reminder to myself as well) could try and put your posts in the context of a location  that will help make the discussion clearer. What is good for southern VA is not necessarily good for northern GA

Ya’ll, it’s now pinned. Could someone PLEASE start a sanitarium thread for one liners, complaints, etc so we can keep this thread clean for information? Also, could ya’ll put locations and for those lurking, please keep in mind where that poster is located.

Speaking through a NC lens mostly:

I think at this point I feel pretty confident in verifying some sort of winter storm across the region this weekend but man are the red flags apparent. AI models have been outperforming the globals and to no surprise (or with our luck), of course they’re north with the coldest air and snow as the warm nose rages during the event. 
 

Last thought: for someone this will be an ice storm for the ages. Idc if the HP is over upstate NY, Ottawa, Iowa, whatever. It’s going to be somewhere in a favorable position and it’s going to be strong. This favors an abnormally large area of mixed precip and stupidly low temps being fed by a steady pump of cold, dry air. Remember, freezing rain is self limited if the cad is in-situ, but not when it’s an anchored HP to the north. Latent heat release can’t compete with that much caa. We’re talking nightmare type of stuff. Sometimes it helps if the precip is heavy, but in the mid 20s, that won’t matter either. 

I was noticing the AI models pushing the warmth further north. Was surprised no one posted about it. I guess we only post what we want to see. I am sure the next 5 days will be a rollercoaster as usual. I just hope we can keep that ZR down at a minimal amount. The Euro AI is actually showing some warmish temps through the storm to keep ice totals down. Should be an interesting week to track.

AI models did well this past weekend with temps. Different setup entirely but both kept central NC in 40s for most of storm while others were way too quick to cool

Done.

A lot will depend on how shallow the airmass is of course with the CAD in place. What we have going for us is the fact that there will be a parent high to begin with. The players are there for sure in looking at the models but as always we need everything to line up perfectly for blockbuster snows. We will see how this plays out. Even if there is some mixing I always remind people that 1/25/00 started off with many hours of rain before the massive snowfall.

The thought of someone getting NAM'ed starting tomorrow night makes it start to feel even more real.

My area in GA is forecast for mid to upper 50's Wed through Friday, then temps dropping. That might be good for me as far as ice is concerned. Wishful thinking??

Mid Atlantic crew are hoping the AI models are right... obviously they are further north. Will be interesting to see which way things go the next couple of days.

I like the Google model. Looks somewhere in the middle of the road with the AI models and the OG GFS and Euro. Probably get a mixed bag of things in central NC with more snow the farther north you are to more ice the farther south you are. Pretty much a classic NC witnter storm.

I don’t really know what to think at this moment. I still think physics based models are better suited here than AI this time because of the AI tendency to underestimate high intensity, be it LPs or HPs. But they are always learning, and that very bias could be lessening as they ingest more data.
 

Really sucks to be sitting here with the best overall solution being the GFS again though. Seen that movie one too many times lately. But please just give me sleet or a warm rain above all that ice.
