Sorry. I meant I'm glad we can identify storm threats at 200 hrs. The message wasn't very clear. 1 Link to comment Share on other sites More sharing options...

We have cold and precip on Monday plus, obviously, it's sooner so less opportunity to fail. I'd really like to see this one juice up in case #2 fails.

Heisy Posted Monday at 03:28 PM Share Posted Monday at 03:28 PM Icon trending towards that Monday/Tuesday overrunning potential. Mitch it’s really amazing how the models generally just follow the Ai when it comes to H5. I wouldn’t use it for temps or precip total, but man H5 is on point . 1 Link to comment Share on other sites More sharing options...

We’ve had one non Nino HECS in the last 40 years and 2 in the last 75 years! We’ve had 7 in a Nino even though those years only make up like 30% of the winters! I think it’s safe to say we shouldn’t expect an HECS in any non Nino year. We’re missing one of the two key ingredients needed to get those level events, a strong STJ. The other being a really strong well placed 50/50 to keep the cold in place as the STJ moisture attacks, typically from blocking but we’ve had a couple where there was a 50/50 without blocking. 7 2 Link to comment Share on other sites More sharing options...

I'm still a little unclear about the STJ. So, we've had seveal southern waves this year...but those are NOT stj but something else? If am active gulf not always an "stj" per se?

87storms Posted Monday at 04:26 PM Share Posted Monday at 04:26 PM That would be an awesome snow chase. Sipping Sazerac hot chocolate eating beignets watch the snow fall on Bourbon Street. You ain’t lying. Was just down there last week. The food was legit. Went to bourbon st one night…it’s like an adult boardwalk lol. I enjoyed Sazerac, though honestly thought beignets were a bit overrated. Pretty impressive turnout for AMS…heard they broke an attendance record. 1 Link to comment Share on other sites More sharing options...

That’s the difference in many events between a 6-12” event and those 20”+ snowstorms. We rarely get those juiced up southern stream bowling bowls throwing some 2”+ precipitatable water moisture feed at us in non Nino years. Further north they can get a hecs without that if the northern streak phases and bombs a storm and it develops a mature CCB with a crazy deform. But we’re too far south for that. We can sometimes get the southern edge of that and in many of our HECS storms we do get an additional 6-12” from that to put us over the top but we had 12+ already just from the STJ overrunning precip. We are too far sorry typically to get 20” from a NS phasing coastal bomb unless it has a strong STJ component initially. 1 Link to comment Share on other sites More sharing options...

I’d be curious to see how much overfitting would impact the models. Might result in more missed fluke events (just brainstorming). 2 Link to comment Share on other sites More sharing options...

Two years from now, all that froth will dissipate and the so and so things we’d never heard of will fall away back into obscurity while we return to the big boys like Microsoft, Apache, etc. 1 Link to comment Share on other sites More sharing options...

Been trying to better understand the math behind svn’s and neural networks. Understanding the loss function and gradient descent are key pieces, but it’s a thick topic, that’s for sure.
