Big time downturn in the SOI last week certainly supports the setup into early next week, and likely favors that energy ejecting out opposed to becoming cut off with the southern/subtropical branch becoming active. www.longpaddock.qld.gov.au/soi/

Unfortunately it looks like things are trending toward a cut-off situation for early next week. We are facing pretty astronomical odds for winter precip before Halloween, but some of those model solutions sure can get you excited. Either way I don't think anyone will be complaining about lack of rain by the middle of next week.

Man it looks real crappy by camping standards setting up next week in Central,Mo. I mean we will be in a cabin. But still I'm not liking the trends with this setup. Ugh...waiting a few more days, but if this trend continues. We might have to cancel. What a bummer that would be.
At first it looked like one storm early week. Now it looks to cut off and come at us in several pieces.

pretty big differences WRT upper low strength with the EURO vs the GFS as they crash onshore the pacnw.
Euro quite a bit stronger thru hr120
and now has the look of a cutoff.

Its a fast flow, but isnt being in a rr quadrant of a jet max a precipitation inducer or am i getting mixed up?

I'd take that pattern all winter long, lol. I just don't want to be stuck listening to snow falling and melting in the middle of the night like last year. It was an OK winter snowfall wise, but everything was 8:1 concrete and melted faster than it accumulated most of the time.

Unless the core of cold airmass shifts to the other side of the pole(which is possible), I don't think availability of cold air will be an issue all winter...it's just about timing.

Thanks snowman99 and jmg378s for your answers! Jmg478, you are so knowledgeable. Is this a hobby for you or did you get a PhD or masters? You would excel if you still decided to do that/get a job related to model computing. Just a hobby I've been able self teach a little bit with meteorology textbooks/journals and other online resources. I do have a masters degree, but it's just in engineering. Though I do mainly software/modelling in my current job it is mostly unrelated to weather and I like it well enough that I've never seriously considered doing anything different.

Correct...and the upper confluence is nearly ideal for cold air penetration into our region with that flow orientation during the winter months...if not a bit too far south. that's what I'm thinking too. II think it a bit unrealistic to expect a pattern in October for anything further south. I I'm sad that next week is wet because I was supposed to get my roof replaced. My routine periodic inspection indicated significant hail damage. In fact, where the hail hit, the granules left the paper exposed. I'm thinking if I don't get it replaced, then after next summer, I start to see dry rot issues with the roof paper, and leaks then could develop. Using March 27 of this year as the date for the hail damage. I don't believe I was home, or I would have storm spotted it. Safeco said, "yeah, that roof is smoked". Getting all new gutters too. They offered to inspect my deck, but I had already power washed it. They asked me if I saw pock marks, but I said that I power wash it and stain it as ongoing maintenance anyway as ongoing maintenance. I probably could have gotten a couple hundred more on that because I know I had pock marks, but my main concern is not having my roof leak and I'm perfectly fine with periodic maintenance of my deck. I do it anyway. Insurance company said the front gutters were damaged, but the roofer said he was just going to replace them all. I know my ex-wife in warrenton texted me pics of the warrenton hail, it was approaching softball size. I don't report hail damage unless I personally witness it, but both her and my son in Foristell replaced their roofs already. My son had a big hailstorm a week after getting his roof damaged. I hope I can get some decent warm weather to give the new roof a chance to seal before the annual blizzards hit. lol. I'm sure we will get a few warm dry days, but now that I know the extent of the damage, I am ready for a roof. I might get me a drone. I have been known to sit in my backyard with a pair of binoculars, and I've called people out to fix flashings that have come loose in the past, but who knows what I can't see. Just wish I could have had a big enough hailstorm to damage my siding. I know I need new siding. That hardboard is crap. That'll be on my dime in a few years.

00z GFS is a smorgasbord bruiser for early next week over the middle part of the country!

Comparing 12z run to 0z run on GFS certainly looks like a further south push of cold air thru 156hrs.

I understand that the cold air connection was lost, but why did the storm peter out and shunt eastward south of us eliminating any rain from it for us...I hope this is not a winter preview.

Too early to get specific, but I like the overall look of the storm on the 00z GFS. A step in the right direction with a further SE wintery storm track. It would involve multiple pieces of energy ejecting with dry time in between of course. And to somewhat answer your question, the placement of the high pressure and convection can play a role in lower precip output on the models. Btrnwxman and snowstorm920 can give you a better answer.

Interesting pattern of rain tonight. Tropical downpours complete with lightning followed by a break of quiet and then another deluge. Even had a lightning hit somewhere not too far away hiccup the power enough to make my UPS's beep once.

Got .49" total from yesterday afternoon and over night. .71" total for this event. Not much, but better than nothing! Brtn, this shower will settle the dust till noon!
