4/11/20 - 4/13/20 Severe Weather Outbreak

HRRR looked like it had a few initial discreet cells, then kinda looked as if it went linear mode for a stretch, but then broke down some and there's still quite a few UHI streaks...



And of course, west of Georgia, it's all quite bad. Been observing that as the run goes on. And it's not very long range HRRR like this stuff is.

Yeah, this one is trying to get that look.View attachment 39050

Just got tornado-warned.

Just got tornado-warned.

That hook looks nasty.

Just got tornado-warned.

That took way longer than it should have. It looked like on radar it had a signature for the past 20 min.

Yeesh, I find those low topped supercells out ahead of the line interesting aswell, but that QLCS looks nasty on the hrrr

The "Southern Piedmont Alley" has made it fairly obvious on every run. Very consistent. Things just seem to be getting worse here as opposed to better.

March 2008 remains undefeated in my lifetime for ATL. Pretty sure it was a 2% marginal risk that night also LOL

It was and that one lone supercell covered a lot of ground. It dissipated well into SC. Irony that I was looking at this outbreaks and others earlier today for similarities in setups. I remember how that supercell also seemed to be a precursor for the next day.

Latest NAM sounding shows a PDS tornado sounding in ATL.

This may end up being a sunrise/early afternoon event for N.C.

Gsp hasn’t really sounded any alarms.

3km NAM backing off cape in the NC Piedmont

 

[Myfrotho704_]

Even with cape backing off, those parameters are still scary , only thing getting my attention is that warm layer around 500mb, could that keep storms more low topped ?

That's what WRAL was alluding to for the Triangle. They said storms would come through Sunday night into the morning, but the stronger ones will be from the morning to midday.

Reminder, no bashing the SPC/NWS for not issuing over-the-top risk boxes for your back yards. They'll likely come if they're warranted.

The 3KM backing off tonight well to the East from GA-Carolinas wasn't too unexpected, in my book. Yes, I know it's still a potentially significant event, but it will not matter if you're under a enhanced, moderate, or high risk (or not). The weather will do what it will do, regardless of certain forecast advisories/terminology.

ARW has a death tube going through AL
