Severe Weather Threat May 17-19, 2025

A bit out of nowhere, but isn't there a bit of rotation all the way up north here in Canada, southern QC, near Saint-Hyatinthe and La Présentation?
Certainly looks like it.
 
Wonder if they’ll upgrade to a 10% for tornadoes.
Ehh, that sounding doesn't really impress me enough to where I believe a 10% upgrade is warranted. LCL's are just under 1000 which doesn't really scream an upgradeable tornado theat. If it was around 800, I think a consoderation would be warranted.

Not to mention, the hodograph doesn't really scream a 10% tornado upgrade.
 
Going back thru SPC event list, this is the first Day 4 30% "Enhanced" in May for North MS since SPC redid the whole Day 4-8 Outlook scheme.
 
Monday and specifically Tuesday is looking like one of “those” days in the plains. Classic plains setup, exponential due points in the 70s. A bowling ball of a low. A very defined dry line. And huge cape. Seems like a thread is necessary because this is looking nasty.

Edit: Gonna also add Saturday and Sunday here too. Since it’s all the same system. (Not trying to cause confusion!) Saturday is indeed looking like the day where this is gonna come in. Haven’t checked the models for these days yet. I did see the SPC didn’t have an outlook for these two days. The potential is there however, gonna be more the lower end days it seems.
Tuesday is a mid south Dixie setup.
 
Thank you.
Also me, her, and granddad got weekly church service later today, but we may have to catch it online if weather get rough.

In meantime, saw this sounding on Twitter:

Even if the tornado threat is not as large today as the coming days, the potential for 2"+ hail over major metro areas could still be a doozy. Insurance is already very expensive for this area and an upper significant hail event would just spike it further.
