Warm sectoring here. Clouds breaking with a beautiful murky sky blue sky

Perhaps even some strong storms around, particularly western areas

maybe this Christmas we'll be ripping severe weather but if we're swallowed by the Walker cell we may not even get any fronts

This is a great point - you would have to figure it is going to take some time for vendors to make the necessary changes and adjustments needed and I would have to imagine this is not going to be an easy task and this is going to require a ton of OT hours. Now, it's also possible many vendors have already been preparing for this as this has been known for a while but I guess the question is how much work could have been completed in preparation for this?

Wouldn't be surprised to see some small hailers tomorrow

Another big source for error too comes from rounding. We only touched upon this briefly but it's an interesting concept to think about - but thinking out loud here, I guess you can consider something like rounding human error. At first glance, something like rounding may not seem like a huge deal but when you're dealing with the computation of tens of thousands (maybe even in the hundredths of thousands or millions?) of equations, errors due to rounding are going to add up quickly and this could very well be a large source for error when you start getting out to say 3 days. You could also argue that modeling is rather accurate out to 15-16 days because when you're getting that far out in time what are your two options really? Modelling and climatology. I never knew this until this was discussed briefly as well in my class, but the reason the GFS is ran to 384 hours is because that is about the cut-off of when modeling has an advantage over climatology. After that time climatology tends to outweigh modelling. Interesting stuff

I know you have stated this over the years and it's something I believe in as well, but introduce quantum computing and improve model initialization schemes and we will see forecast accuracy improve drastically - and not just accuracy but we probably see less wavering. But who knows...maybe this is a nice theory lol

Part of the degrading in forecasting too is all of these stupid products that exist. Model snowfall maps, Freezing Rain Accumulation maps, Supercell Composite Parameter, Significant Tornado Parameter, the stupid hazard type at the bottom right of the SHARPpy forecast soundings, maybe throw updraft helicity swaths in here too

NBMv5 became operational last week. Curious to see how this performs.

If everyone thinks its dry now just wait until we move into Fall and Winter. With a super, super, super strong EL Nino coming the Walker Circulation is going to get so expansive and swallow the entire U.S. There will be no storm track...just a massive high pressure from coast to coast. We'll be seeing highs in the 80's into November and highs in the 50's and 60's through the winter. No precip

I was just going to comment on this

I'm pretty sure that supercell is producing a waterspout that is sucking Great White Sharks out of the Gulf

Nice classic supercell just off the western Florida coast

I wonder how rare Blowing Dust Advisories are in Illinois

Maybe we can try sneaking in an EML ~next Tuesday

There definitely is some support for the typical torch spots to hit 90

Looking at some significantly warmer periods coming up but should be active with the fropas too. However, the theme should be much different than we've seen with cool dominating. Should be warmer days winning out with a day or two of cooler temps post fropas

Some people must think we live in the Amazon or something. You'd think we're supposed to average like 70+" of rain a year

Today absolutely blows. Saying today is depressing is an understatement

HRRR did pretty well yesterday having these showers moving through

Well so much for lasting until Fall I’ve been wanting to hold off longer, but my girlfriend had been looking at shelters and came across Izzy and fell in love with her. She was found around a gas company by some employees and had a leg injury. They had paid for the surgery and brought her to the shelter. we went to go meet her last night. Unfortunately, she came down with a cold and because she is being treated we can’t legally take her across state lines. So hopefully we will be able to bring her home Tuesday or the following Tuesday.

what about adding NBM and NBM probabilities?

This is pretty cool!

I wonder if the below average precipitation departures (not just in our region but within the country), particularly the last several years are a product of what seems to be the peak of the +AMO regime. Or I shouldn't say directly related because there are always other factors but perhaps a large driver.

Let's do it
