Whoa moderate risk! 45 hatched wind area, I'm back in the enhanced.

I'll have to go back and take a look later but I believe this might be the first moderate risk in OK in February since 2009 (if it's still there on the day 1 outlook which it should be)

Impressive event whether it's the squall or the winds behind it. Window for discrete/semi-discrete supercell is small but I can't imagine it'll take long for one to develop based on the shear. I see SPC also mentioned the potential for a strong tornado in this small window. Could easily go without seeing one but certainly worth mentioning. I think it would be somewhere between where the 5% tornado starts and where the 45% wind starts. Very small area.

Safe to say we probably won't see model kinematics like this again in the Plains this year, though we often don't need something so extreme.

Dixie Alley kind of wind field. Sure hope there's not a localized area where there's more low-level instability.

Goodness gracious! I do sadly think that we are going to see something like this in the Plains later this year as the La Nina dies away, the Plains is overdue for a nasty Spring Season, it's been generally quiet for the past 3 years in the Spring.

(Also deciphered the location to be ENE of Watonga, OK)

Today is no joke. Red flag warning in the west, a high wind warning for 40-45 mph sustained winds gusting to 70, and obviously this severe threat.

Crap! I'm under the Moderate risk! Storm Shelter is ready though.

 

There could be some room for a High Risk of Destructive Winds for this.

I don't think the SPC would introduce a high risk unless we got a 60% hatched for wind and/or the tornado threat was upped to at least 15%, that being said I don't think that happens, Either way definitely going to be a crazy day in the plains!

There hasn't been a 60 hatched wind since 2014 so I doubt they upgrade

I know it's unlikely, but you never know. There are signs that the Dew Point is increasing across Northern Texas and into Oklahoma as the Moisture Return may have started to be well underway.

Well I mean it's never impossible... Just very highly unlikely. 45 hatched though is no joke

None of the derechos over the past 15 years that stick out in our mind were high risk days. That brings up two points... high risks solely for wind are the most rare kind of high risk, and the high-end derechos we've seen were just moderate risk days. They easily could've verified as high risk days, but they weren't. I honestly wonder if there's a push to make 60% hatched wind days moderate risks.

The last few runs have been consistently showing a 2-3 hour period where we could definitely see a couple supercells, I doubt they'll go higher than 10% hatched but I could see a slight expansion of the 10% north along the Texas panhandle/OK border.
