Forecast Discussion - April 15, 2024 - Multi-Day Severe Weather Outbreak Begins Today
Ғылым және технология
For educational purposes only. If you live in the affected areas, please stay tuned to your local National Weather Service office for the most accurate and up-to-date information.
An outbreak of severe weather is expected to begin today across the Plains before shifting east into the Midwest/Mid-South tomorrow and Wednesday. The SPC has outlined an Enhanced Risk (level 3/5) across southern South Dakota and much of Nebraska down into western Kansas. Supercells are expected to fire in multiple areas by early evening, including ahead of the surface low/along the warm front and along the dryline. Very large hail is possible, and an intense low-level jet will yield a strong tornado threat with any discrete supercells from central Nebraska into southwest Kansas.
The threat shifts east on Tuesday; the SPC has outlined an Enhanced Risk (level 3/5) for parts of Iowa, Missouri, and Illinois. As long as destabilization and storm mode cooperate, supercells with very large hail and tornadoes, perhaps strong, are possible in this area. A separate area of severe storms may occur along the stalled Pacific front across eastern Oklahoma and western Arkansas. What happens on Tuesday will modulate what happens on Wednesday, but severe storms are possible on Wednesday across Indiana, Ohio, Kentucky, and a small sliver of Tennessee.

Man, you and Reed said that the nose of the instability was the place to be 3 days ago. And now look where the target is. Great work as usual

In omaha, and my parents are a little south of des moines so hoping to see some stuff from afar but not on top of us 🤞
Hopefully, this will hold off until i get off work tomorrow 😩. I hate to miss an almost slam dunk chase opportunity. I'm hoping anything that drops stays super rural and doesn't bother anyone. No more mass-casualty events at St Luke's, please! 😳 Edit: Thanks Trey, awesome discussion! Brilliant as usual.😊

Thanks for doing these. I usually read the discussion on the SPC outlook when I'm in an area of concern, but it doesn't go nearly as in depth. I'm just east of DSM so I'll be watching tomorrow
As expected this is gonna be the significant event that was hinting a few days ago. Man the hail is gonna be nuts and the tornado risk is gonna be pretty much just a good I think. These brrroooad 5% usually over-perform well but Tuesday.....that's the day to really eye on. Actually I think both days will be pretty good tornado producers overall. I get models were kind of being strange on this but the dew points are well in place for something to go pretty substantial in KS tonight and NE. Pretty sure we will see a decent tornado outbreak on both days.....actually even Wednesday is trending to be a pretty hot day for all hazards again in the OH River Valley. This truly is trending to be an unreal April-June. It's actually amazing how much discrete potential the models are now showing next 2 days. This has actually he best chance so far to see very strong and powerful tornadoes so far and honestly....all the boxes are in place for it. I will also not be surprised is this ceiling for today is a poor man's April 2012.
First! Thanks for this Trey!

How much do the HRRR and other models use analogs like the dates you have mentioned when they are generating a new run?

@@PartlyDeaf I don't really think analogs are part of the model schemes themselves, but they can spit out analogs as they're running (e.g. the Sounding Analog on the model soundings)
It's been quite disappointing the last couple of days when it comes to severe weather. (besides the severe weather day in Louisiana) Let's just hope that it will be a bit more 'interesting' this time. Thanks for the discussion Trey!

Your videos are always so awesome! Not sure about this one. My target area is Eastern IA/Western IL. I am a little apprehensive about chasing given that I chased the mod risk area South Indy into Ohio a little bit ago. That was a bust. I always do my own forecasting but didn't for that one and trusted the models. Also, forecast hodographs aren't very impressive.
@ConvectiveChronicles

Thank you! Yeah, I think there are a lot of issues with the setup: morning convection, early initiation, etc. Probably will be a few tornadoes but I don’t see a widespread event.
I'm in northern Oklahoma. After twenty years living in this state, I've learned to pay attention to how the air feels. It's got the feel to it today and I haven't felt that in a long time.

Hey, I watched through the video. Most of it is far over my head. In the HRRR on Tuesday, there seems to be a quick and strong spin up near Little Rock, AR. Do you think that will be accurate? I've got interpreters going home around that time and I've been trying to decide if we need to let them go home early.

I wouldn’t put too much stock in the HRRR more than a few hours away from an event. Still, be prepared for scattered severe storms with an all hazards risk.

European events are interesting, and I'd love to see them done but there's a lack of data, radar with velocity or cc in most worldwide areas. I will try my best to find leads, but historical data I'm not really sure if I can despite my research skills. I'll do a bit of searching soon

In your last video you made a comparison to the 2007 Greensburg supercell. In which any tornadoes that may be discrete before nocturnal cooling could become significant. What are the chances of that occurring since we’re closer to storm initiation?
@ConvectiveChronicles

Chances have increased since the last video. Obviously, Greensburg is an incredibly high end event, so it’s unlikely that anything like that happens, but be prepared regardless.
