00:00Joining me right now is AccuWeather Severe Weather Expert Guy Pearson.
00:03You know, Guy, you and I were talking the last couple of days.
00:05This overall pattern across the plains very much has a feel of July and August.
00:13And in this part of the country, this is an area that you deal a lot with nocturnal thunderstorms.
00:20That is, thunderstorms that are mostly during the overnight hours.
00:23It's a fascinating process.
00:25I want you to explain to our viewers, especially living where you live,
00:29in Wichita, you see it a lot.
00:31Explain how that process works and how it's a little different than what we see during the day.
00:39Yep, certainly.
00:41And, you know, a lot of it does start with the heat and the moisture that's already in place, right?
00:46So during the daytime, all that heat builds across Texas, Oklahoma, even Kansas,
00:52and works its way north.
00:53So, you know, with the high pressure area here, with the directional clockwise winds around it,
00:59it's helping to move that moisture and that heat farther north during the day.
01:04And so you can sort of see our cluster of storms from this morning that sort of moved across the Red River,
01:08and that sort of moved across overnight, right?
01:10It's all part of this process of you get a complex that starts to develop towards the evening time frame,
01:17and there's other processes then that take over after that to help maintain it
01:22and help it continue through the evening and to the overnight hours.
01:26Well, here we go.
01:27You were looking at that area.
01:28There's that line of thunderstorms.
01:29Now, thankfully, I've not seen any severe weather.
01:32You and the forecast team, you believe that this will likely weaken as we go through the morning here
01:39as it approaches the Dallas-Fort Worth area?
01:42Yeah, I've actually taken a little bit of a look at it,
01:48and it intensified a little bit to where maybe there's even some small hail with it,
01:53maybe some penny-sized hail and certainly some gusty winds, 40 to maybe 50.
01:57But it will continue to deteriorate as we go through the rest of the morning here
02:01as it does continue to slide east-southeast.
02:05And then later today, watch the afternoon processes take over.
02:08You get some heating.
02:08I'll tell you what, there's no place, there's no place like home,
02:13but there's no place like the Southwest Plains and West Texas when it comes to thunderstorms.
02:18Guy, I always say this, thunderstorms in this part of the country are never run to the mill.
02:22They always have what?
02:23Wind and hail.
02:24These look like some nasty thunderstorms later today.
02:29They do.
02:30They've got sort of the next piece of energy starting to come out
02:34as well as then all the key ingredients for thunderstorms to develop.
02:38And you can sort of see they are a little discreet here.
02:41So they're going to have their own sort of inflow, undisturbed air coming in
02:44to really maintain those thunderstorms.
02:47Certainly some hail, large hail golf ball size,
02:51as well as then damaging winds and even an isolated tornado or two.
02:55That thunderstorm north of Lubbock looks very suspicious to me, Guy.
03:00Now, I know it's the model, but it has that bent stretch kind of look
03:04that you can see with these thunderstorms that you typically would then get to tornado
03:08on the southern side.
03:09Do you see that as well?
03:13Yep, it does look like, as I've sort of looked at this,
03:16some of the in-between hours as well.
03:18We have those little individual discrete cells that do get strung out a little bit,
03:22and typically those are the ones that, you know, if they are going to,
03:26one, it just shows that there's a good strong updraft to be able to produce hail,
03:30and then beyond that, with the additional rotation,
03:33then maybe we'd have one or two there that would produce a tornado with it as well.
03:37And then here's the nocturnal process.
03:39Thunderstorms weaken across the Red River, but there it is.
03:42By late tonight, tomorrow morning, severe weather threat
03:45as we head toward late tonight, tomorrow morning,
03:47including West Texas and Oklahoma City.
