Maestrobjwa Posted February 12, 2022 Share Posted February 12, 2022 Eh, PD weekend period not lookin' so good...Looks like the never-ending parade of NS vorts scour out any cold the big cutter leaves behind. Link to comment Share on other sites More sharing options...

Pretty good broad look analysis identifying a common problem and why it's a problem. Anytime shortwaves are zipping north of us, there is a period of return flow sucking warm mid level air up from the south. Even with insitu cold underneath and overhead, it's an efficient airmass rotter and not something to ever be ignored at our latitude. North of us can get plenty of snow with return flow stuff. We usually get rain. Eta: Models can't resolve this stuff far in advance though. There have been countless times in the past where those NS vorts magically appear and disappear in the mid range. With a NS dominant pattern you always need to be looking at those when it counts 1 Link to comment Share on other sites More sharing options...

I never have quite understood how that worked...(although I'm guessing a bunch of those lows to the north is one way it DOESN'T work...lol) Link to comment Share on other sites More sharing options...

They don't say why, though. ENSEMBLES AND DETERMINISTIC MODELS HAVE NEARLY 80 KNOTS OF WINDS AT 850 WHICH SUGGEST THAT WE WILL HAVE SHEAR WELL OVER 60 KNOTS AS THIS FRONT PASSES THROUGH THE REGION. ALTHOUGH CAPE AT THIS RANGE IS FORECAST TO BE RELATIVELY LOW, I SUSPECT THE CAPE IS BEING UNDERDONE. IF WE ARE ABLE TO GET EVEN A FEW HUNDREDS OF CAPE COMBINING WITH 60+ KNOTS OF SHEAR, THE REGION COULD SEE A DECENT SVR THREAT. 2 Link to comment Share on other sites More sharing options...

I never have quite understood how that worked...(although I'm guessing a bunch of those lows to the north is one way it DOESN'T work...lol) Any strong cutter with the correct track will pass through the 50/50 region. It's a climo thing. 50/50s happen all the time but are usually transient meaning they are just passing by the sweet spot. When timing is linked up with something upstream, a 50/50 goes from completely unnoticed to the most important thing in Ji's life. We don't just need 50/50s. We need them linked up with other stuff. So basically, in a progressive pattern, you need 2 swift moving targets to be in the proper place at the same time. Tall order and often why they don't work. It's not bad luck. It's statistical probability. Blocking will lock at 50/50 in place. We still need 2 things to link up but only one is moving in that scenario. Far better odds and why we drool over that stuff 1 1 Link to comment Share on other sites More sharing options...

I was about to say...the only time wind is worth getting somewhat excited about is when it does things like this...lol While it was still a bit bittersweet because it came from a NE, Miller B-ish blizzard that just missed us, to have a pure wind event like that was pretty incredible (and somewhat anomalous, no?)

I think 3 days ago this was a driving rainstorm with very strong slp headed through Illinois or Indiana. Hopefully the ns continues the seasonal trend and drags the boundary even quicker across What is a CF? 1 Link to comment Share on other sites More sharing options...
