Tl;dr — “replacing” or competing with NWS alerts could be problematic, but I don’t see what Ryan is doing as that. And
@BluekandyWX
, who is a brilliant met colleague, is helping power it. I trust his expertise.

Folks should wait to see how it’s implemented before opining much.

No agency is infallible — whether private sector, government, broadcast, etc. Supplementing existing alerting (and occasionally patching gaps) isn’t a bad thing so long as there isn’t confusion over the source of the alert. That’s a careful thing to manage. [2/3]

I issue manual alerts via the MyRadar app — sometimes to a few million people at once, and sometimes on hyperlocal levels. We’re working to expand our push alerting even further. We haven’t branded them as watches/warnings, but similar premise.

I never get tired, and yet lately society just seems exhausting. Maybe I’m just old and grumpy now. TBD.

Anyone else feeling burnt out re:social media and the internet lately?

The tone, volume and nature of comments, messages and responses just seems different than even a year ago.

Am even noticing a shift with my student/parent interactions too. Public seems on edge.

I’m going to dissent from the rest of WxTwitter here — I don’t have an issue with this if done correctly.

From what I can tell, Ryan is branding it as a “heads up — stay tuned for NWS alerts that may be coming.” That’s fine.

We all do that to some extent informally. [1/3]

Growing concern for THURSDAY in the Upper Midwest/Great Lakes, where we could have some tornadic supercells.

Early forecasts suggest the potential for rotating supercells – with an attendant tornado risk – that may eventually merge into a line. Once they merge later Thursday evening, the threat for tornadoes would wane and the predominant threat would become damaging straight-line winds.

Uncertainty is still high, and we're not yet close enough to the event to draw insight from CAMs, or Convective-Allowing Models. In other words, the models this far out can't "see" or simulate thunderstorms – but rather the overarching environment.

WHAT WE KNOW: A potent upper-level low pressure system is set to swing across the Northern Plains and Upper Midwest. Ahead of it, an unseasonably warm, humid air mass will be drawn north, contributing to instability, or thunderstorm fuel.

The low will sweep a cold front east, which will push into that juiced-up air mass and trigger storms.

Our stubborn cutoff low continues to bring downpours and a localized flooding/tornado risk across the Southeast:

A very active severe weather stretch begins Wednesday and lasts into early next week.

If you live in the Corn Belt, Upper Midwest, western Great Lakes or Plains, you’ll want to pay attention through Tuesday.

The jet stream will dip over the western U.S., allowing cold air and low pressure to take shape over the Rockies. Periodic disturbances will eject eastwards, encountering warm, humid air and generating storms.

WEDNESDAY, May 14: Low pressure organizing over North Dakota will swing a cold front east. Thunderstorms will form around 4 p.m. in central Nebraska and the Dakotas. Moisture will be meager, so expect high cloud bases. That cuts back on the tornado threat. The main hazards will be damaging winds around 60 mph and some quarter-sized hail. Storms will quickly merge into a line and push east toward Interstate 29 after sunset

La amenaza de supercélulas con todos peligros —tornados, vientos dañinos y granizo grande y destructivo— está aumentando.

Especial preocupación por el Medio Oeste, las Llanuras y el Sur Medio. Erica López tendrá una actualización por la mañana.

Adam makes some great points here, and exemplifies the importance of following the science rather than just hugging models.

Chasers and meteorologists alike come to understand model biases and cultivate a pattern recognition/intuition over time.

A cool discussion on moisture:

Genuinely curious what Nadocast is seeing that I’m not…

Sure, I could see a discrete cell or two pop, but between higher cloud bases and quick upscale growth, it just seems like a long shot.

Anyone else have thoughts?

*Weeklong severe weather sequence begins today*

May is peak tornado season, and we’re about to see a dramatic uptick in severe weather across the central and eastern United States.

Here’s a general rundown of what to expect – and when.

1 hour and 40 minutes later, I’m back.

Apparently maintenance does not start their day until 7 AM so I can’t get in until then

Going back to bed. I will try starting my day when the universe is ready for me and my wonderfulness.

Don’t try me today, people. The hotel waffle maker is broken.

Maintenance does not appear to have showed up at work so I will not be getting into my hotel room any time soon.
