WEBVTT 1 00:00:00.080 --> 00:00:03.000 Box thirty one's chief meteorologist, Day Fraser, Ainy Day Fraser, 2 00:00:03.000 --> 00:00:03.640 what about this. 3 00:00:03.720 --> 00:00:07.080 Dug and gloomy skies today? What's happening? 4 00:00:08.119 --> 00:00:11.160 Weeah that nice refreshing change, thanks for cool front last night. 5 00:00:11.480 --> 00:00:14.320 So instead of baking at ninety five like we did yesterday, 6 00:00:14.320 --> 00:00:17.480 we'll only pop out in the in the mid eighties today. 7 00:00:17.559 --> 00:00:19.920 So that's that's the benefit of the dark and gloomy 8 00:00:19.920 --> 00:00:22.079 skies out there. But the price that comes with it 9 00:00:22.160 --> 00:00:25.039 is a chance for showers and thunderstorms, some of which 10 00:00:25.800 --> 00:00:29.559 will have lightning and wind and hail typical threats, and 11 00:00:29.600 --> 00:00:32.640 so we'll watch for that this afternoon. But the humidity 12 00:00:32.719 --> 00:00:35.359 level is higher today, I'm sure everybody by Colorado standards 13 00:00:35.399 --> 00:00:37.920 just about that, and that can lead to heavy rain 14 00:00:38.200 --> 00:00:41.079 but hopefully beneficial range. So there's a there's a trade 15 00:00:41.119 --> 00:00:43.359 out right, Maybe keep the hail on the small side. 16 00:00:43.439 --> 00:00:45.719 We don't get any damage, but we can ring out 17 00:00:45.719 --> 00:00:48.039 some rain this with this higher humidity, and that's what 18 00:00:48.039 --> 00:00:48.679 I'm hoping for. 19 00:00:48.960 --> 00:00:51.079 Well, let me give out the text number if people 20 00:00:51.079 --> 00:00:53.600 have weather questions. Now's the time, five sixty six nine. 21 00:00:53.679 --> 00:00:56.840 Oh is who you text? Yesterday? I was driving home 22 00:00:56.920 --> 00:00:58.799 and I was all excited because I was driving through 23 00:00:59.000 --> 00:01:02.479 really like health rain, right, good rain, and then drove 24 00:01:02.479 --> 00:01:04.200 into my neighborhood and not a drop and I was like, 25 00:01:04.319 --> 00:01:06.159 dang it, now I've got to water on my plants. 26 00:01:06.599 --> 00:01:09.319 So how scattered are these showers? 27 00:01:09.480 --> 00:01:11.239 When are we I mean, when are we going to 28 00:01:11.319 --> 00:01:13.400 see like a solid line where I know I'm going 29 00:01:13.439 --> 00:01:13.920 to get rain? 30 00:01:14.120 --> 00:01:15.040 When am I going to get that? 31 00:01:16.879 --> 00:01:20.439 You know, when we're dealing with storms of convective nature, 32 00:01:21.079 --> 00:01:23.280 you know, it just depends where the first ones go up. 33 00:01:23.280 --> 00:01:26.519 And then we always talk about outflow boundaries. When the 34 00:01:26.519 --> 00:01:29.280 thunderstorms are kind of dying, they can throw a gush 35 00:01:29.359 --> 00:01:31.599 of wind across the ground and that can be a 36 00:01:31.680 --> 00:01:36.439 focal point for additional development. Those things, even the highest 37 00:01:36.480 --> 00:01:38.560 resolution models don't do a good job picking up on, 38 00:01:38.840 --> 00:01:41.079 so you kind of have to watch the radar real time. 39 00:01:41.439 --> 00:01:43.599 I will tell you if you're going to get your 40 00:01:43.680 --> 00:01:46.359 rain up and down the front range. As I'm looking 41 00:01:46.400 --> 00:01:50.280 at our high resolution models, it's going to start. The 42 00:01:50.400 --> 00:01:52.680 clouds are going to delay the start because they're delayed 43 00:01:52.719 --> 00:01:55.439 the heating. So obviously heating is a component to get 44 00:01:55.480 --> 00:01:58.400 the storms going. I'm thinking we're going to be somewhere 45 00:01:58.400 --> 00:02:00.920 in the two to three o'clock start. I think the 46 00:02:01.000 --> 00:02:04.519 best window goes till about five o'clock, and by five 47 00:02:04.599 --> 00:02:07.159 to six they're starting to push past the airport and 48 00:02:07.159 --> 00:02:09.159 go onto the eastern planes. So if you're going to 49 00:02:09.240 --> 00:02:11.800 get the rain, you're going to have to see it 50 00:02:11.840 --> 00:02:14.080 by five to six. If you haven't seen it by 51 00:02:14.120 --> 00:02:16.479 five to six, your only hope would be that an 52 00:02:16.479 --> 00:02:19.680 outflow boundary comes back in your direction, But chances for 53 00:02:19.759 --> 00:02:21.400 that in this type of environment are going to be 54 00:02:21.400 --> 00:02:24.800 on the very low side. So that's your window coverage 55 00:02:24.840 --> 00:02:27.800 is about sixty percent, Mandy. So I know a lot 56 00:02:27.800 --> 00:02:29.639 of people think that that means though there's a pretty 57 00:02:29.639 --> 00:02:31.840 good chance you know that you'll get rain, it's decent. 58 00:02:32.240 --> 00:02:33.840 It means a lot more of us have a better 59 00:02:33.960 --> 00:02:36.080 chance of seeing it, but it's not one hundred percent, all. 60 00:02:36.039 --> 00:02:39.520 Right, So we got a couple of questions, and funny, 61 00:02:40.680 --> 00:02:45.120 I have three different questions from three different textures, and 62 00:02:45.159 --> 00:02:48.520 they are all about the use of the word land spout. 63 00:02:48.599 --> 00:02:50.000 Let me read them all to you in one one 64 00:02:50.000 --> 00:02:52.000 little fellow swoop here, Hi, Mandy, can. 65 00:02:51.919 --> 00:02:54.199 You ask Dave what a land spout is? Mandy? 66 00:02:54.240 --> 00:02:57.680 For Dave, difference between a land spout and a dust devil. 67 00:02:58.000 --> 00:03:01.520 Mandy Weather Wednesday question. Please ask Dave when and why 68 00:03:01.599 --> 00:03:04.879 did they start calling tornadoes land spalves. So let's clear 69 00:03:04.960 --> 00:03:07.879 the air on landsfalts, shall we yep? 70 00:03:08.479 --> 00:03:11.280 So let me start with the lower end, the dust devil. 71 00:03:11.719 --> 00:03:15.759 The dust devil is exactly that. As the ground heats, 72 00:03:16.680 --> 00:03:20.759 the air rises, and if it heats a finite area, 73 00:03:20.960 --> 00:03:22.759 you can get the air to rise and kind of 74 00:03:22.759 --> 00:03:26.599 swirl a little bit. Generally, a dust devil doesn't do much, 75 00:03:26.639 --> 00:03:29.560 and it doesn't connect to the upper atmosphere, and it 76 00:03:29.599 --> 00:03:32.080 only lasts as long as it's over that heated source 77 00:03:32.560 --> 00:03:34.919 and then it dies away. So if a dust level 78 00:03:34.960 --> 00:03:36.759 comes up and it moves over an area that's cooler, 79 00:03:36.800 --> 00:03:39.960 it's just going to die out. The next one would 80 00:03:39.960 --> 00:03:43.400 be the land spaluve and land spout tornadoes, and that's 81 00:03:43.719 --> 00:03:47.120 the frase you'll hear us use are defined as tornadoes. 82 00:03:47.639 --> 00:03:51.280 It's just that they form in a different way. So 83 00:03:51.400 --> 00:03:55.120 a tornado is generally associated with a large thunderstorm or 84 00:03:55.120 --> 00:04:00.560 a cumulomimous cloud. The whole storm is rotating and the 85 00:04:00.560 --> 00:04:04.120 tornado drops from the center of the storm down to 86 00:04:04.199 --> 00:04:08.159 the ground. And that rotating column of air can be violent, 87 00:04:08.199 --> 00:04:10.680 and as we know, we have categories for them or 88 00:04:10.759 --> 00:04:13.000 a zero one two through the EF scale that we 89 00:04:13.080 --> 00:04:15.080 talked about all the time. And the stronger the wind, 90 00:04:15.120 --> 00:04:16.920 the more damage you're going to have. The storms can 91 00:04:16.959 --> 00:04:19.720 be very large. We don't tend to see them. Most 92 00:04:19.720 --> 00:04:22.120 of Colorado deals with E F zero EF one. They 93 00:04:22.120 --> 00:04:26.079 don't last all that long. A land spout is in essence, 94 00:04:26.120 --> 00:04:29.040 a dust devil that starts on the ground because of 95 00:04:29.079 --> 00:04:34.040 heating or swirling wind, and as a thunderstorm is growing, 96 00:04:34.600 --> 00:04:37.639 just starting to develop, it acts like a suction or 97 00:04:37.639 --> 00:04:41.800 a vacuum, and it stucks that rotation up and connects 98 00:04:41.839 --> 00:04:43.560 it with the cloud and gives it a little more 99 00:04:43.639 --> 00:04:46.480 spin up and so it grows from a different direction. Now, 100 00:04:46.480 --> 00:04:49.720 the lamp spout that did the damage in Franktown yesterday, 101 00:04:50.160 --> 00:04:53.720 most lamp spouts do not do damage. They last, they 102 00:04:53.720 --> 00:04:56.199 don't last very long, and their speeds are very very low. 103 00:04:56.720 --> 00:04:58.199 But I mean, you don't want to be in one. 104 00:04:58.279 --> 00:05:01.759 I mean feeling even stung by bees. The one that 105 00:05:01.839 --> 00:05:03.759 hit frank Down came up and hit the corner of 106 00:05:03.800 --> 00:05:05.319 a building. It looks like it took a roof off 107 00:05:05.360 --> 00:05:09.759 of a commercial property that one only lasted ninety seconds, 108 00:05:10.439 --> 00:05:13.600 But ninety seconds enough. Here's the problem when it comes 109 00:05:13.639 --> 00:05:16.480 to land spouts. The radar the start at the ground. 110 00:05:16.639 --> 00:05:20.959 The radar cannot point directly to the ground radar right, 111 00:05:21.040 --> 00:05:23.600 so the radar is pointing over the horizon. So the 112 00:05:23.639 --> 00:05:26.199 farther out you get from the radar, the beam is 113 00:05:26.199 --> 00:05:28.319 getting higher and higher and higher off the ground because 114 00:05:28.360 --> 00:05:30.600 of the curvature of the earth. So because the radar 115 00:05:30.639 --> 00:05:32.720 is not pointed at the ground, it's pointed more in 116 00:05:32.759 --> 00:05:34.839 the middle aspect of the storms where we can see 117 00:05:34.839 --> 00:05:38.920 the rotation. You don't get the notification of anything happening 118 00:05:39.000 --> 00:05:41.120 until it grows tall enough that it might be able 119 00:05:41.160 --> 00:05:43.319 to be seen by radar. So, in essence, we can 120 00:05:43.360 --> 00:05:46.879 be blind in those respects when it comes to the technology. 121 00:05:47.120 --> 00:05:50.680 Once it connects, it can grow tall, and generally the 122 00:05:50.720 --> 00:05:52.800 base of the thunderstorm is way up high, and sometimes 123 00:05:52.839 --> 00:05:54.600 you'll be able to see it growing up and it 124 00:05:54.639 --> 00:05:57.439 does visually look like a tornado, it's just a different formation. 125 00:05:57.600 --> 00:05:59.560 So but does it ever become a tornado or is 126 00:05:59.560 --> 00:06:02.120 it all a land spout and it's always a tornado 127 00:06:02.199 --> 00:06:03.240 based on how they start. 128 00:06:04.360 --> 00:06:06.680 Now it's because of the way it started. It's not 129 00:06:06.839 --> 00:06:09.759 going to the storm that's generating. It is not the 130 00:06:09.800 --> 00:06:14.720 typical formation of a classic rotating funderstorm. It's basically the 131 00:06:14.759 --> 00:06:17.839 thunderstorm is growing and the air going into the thunderstorm 132 00:06:17.920 --> 00:06:20.519 is kind of drawing up that land spout, if you will. 133 00:06:20.759 --> 00:06:23.959 The cloud itself is not generating the rotation in the spent. 134 00:06:24.240 --> 00:06:28.000 Okay, so it sounds to me as a Floridian. A 135 00:06:28.160 --> 00:06:30.480 land spout is the same as a water spout on 136 00:06:30.519 --> 00:06:31.199 the water. 137 00:06:32.279 --> 00:06:36.560 So yeah, it can be. But sometimes water stoups can 138 00:06:36.639 --> 00:06:39.040 be tornadoes that form over water, and they define them 139 00:06:39.079 --> 00:06:41.160 as water stops because they're over water. 140 00:06:41.319 --> 00:06:43.160 Okay, I've actually been in the Gulf. 141 00:06:43.639 --> 00:06:45.399 Yeah, I've been in the Gulf of Mexico on a 142 00:06:45.439 --> 00:06:47.800 small boat when I watched a land spout form and 143 00:06:47.839 --> 00:06:49.439 it was one of the coolest things I've ever seen 144 00:06:49.480 --> 00:06:52.680 in my life and also super terrifying. So I didn't 145 00:06:52.759 --> 00:06:55.360 enjoy the as we were running away from it as 146 00:06:55.399 --> 00:06:58.480 fast as we could, but it was really fascinating to 147 00:06:58.480 --> 00:07:01.759 see it happen in real time. It was really super cool. 148 00:07:01.879 --> 00:07:04.279 Here's one for you, Dave. Ask Dave if a dust 149 00:07:04.360 --> 00:07:06.639 devil is related to the Tasmanian Devil. 150 00:07:09.120 --> 00:07:12.199 Or the vice versa. Yes, the Tasmanian Devil is related 151 00:07:12.199 --> 00:07:14.839 to the dust level. Yeah, because dust devils. We all 152 00:07:14.839 --> 00:07:17.759 know the cartoon, right, Yes, swirled the dust devil in 153 00:07:17.759 --> 00:07:20.879 the cartoon, you know, bugs Bunny and the Tasmanian Devil, 154 00:07:20.920 --> 00:07:23.920 a swirling pile of dust creating chaos. And so yeah, 155 00:07:24.079 --> 00:07:26.399 I think it's interchangeable. Which came first, the chicken of 156 00:07:26.439 --> 00:07:27.399 the egg. I can't tell you. 157 00:07:27.920 --> 00:07:29.199 This is a serious question. 158 00:07:29.600 --> 00:07:30.279 They need. 159 00:07:31.199 --> 00:07:34.560 The smoke here on the western slope is awful. Please 160 00:07:34.600 --> 00:07:36.639 ask Dave if there's any relief coming dust in the 161 00:07:36.680 --> 00:07:39.800 next week. We've got some big fire fires burning on 162 00:07:39.920 --> 00:07:42.839 the western slope the border of Utah. Is there any 163 00:07:42.920 --> 00:07:44.800 rain coming to give any relief from that? 164 00:07:45.920 --> 00:07:49.079 You know? Unfortunately, the long range outlook for the next 165 00:07:49.120 --> 00:07:51.560 six to ten days does keep the western slope dry. 166 00:07:51.680 --> 00:07:54.759 They struggle at this time of the year. We're benefiting 167 00:07:54.800 --> 00:07:57.000 from a cold front that came in from the east 168 00:07:57.040 --> 00:07:58.800 last night. They did not make it up and over 169 00:07:58.800 --> 00:08:00.920 the mountains to the west. So while there will be 170 00:08:01.000 --> 00:08:06.040 spotty storms over the west, for instance, the San Juans tomorrow, 171 00:08:06.120 --> 00:08:08.160 the San Juan Mountains in the southwest. We'll get some 172 00:08:08.279 --> 00:08:12.279 small storms out there. I don't see a huge relief coming. 173 00:08:12.319 --> 00:08:15.920 I don't see a widespread rain event enough to you know, 174 00:08:16.079 --> 00:08:19.639 put the fires out. The hope with the smoke might 175 00:08:19.680 --> 00:08:21.720 be that if we can get a little wind to 176 00:08:21.839 --> 00:08:23.600 stir it and get it up in the way. They 177 00:08:23.600 --> 00:08:26.160 do have air quality alerts right now for the west 178 00:08:26.199 --> 00:08:28.360 and southwest part of the state because of the smoke. 179 00:08:29.120 --> 00:08:31.360 It's unfortunate. But that part of the state We've talked 180 00:08:31.399 --> 00:08:33.840 about it for months and months and months, is the 181 00:08:34.000 --> 00:08:35.840 part of the state. The eastern half of the state 182 00:08:35.879 --> 00:08:38.000 has no drought. The western half of the state is 183 00:08:38.000 --> 00:08:41.080 still druggling its drought and the trade off for rain 184 00:08:41.240 --> 00:08:43.799 chances may come with lightning, and that of course can 185 00:08:43.840 --> 00:08:47.639 spark additional fires. I mean, we've seen the news. You 186 00:08:47.639 --> 00:08:53.159 know what's happening down in the Grand Canyon area in Arizona. 187 00:08:53.360 --> 00:08:55.679 You know, unfortunate to see that the lodge was lost 188 00:08:55.679 --> 00:08:58.039 and stuff. So the west is struggling a little bit. 189 00:08:58.080 --> 00:09:00.000 I just don't see a big enough storm right now 190 00:09:00.120 --> 00:09:02.960 to help. But any wind can help disperse the smoke, 191 00:09:03.039 --> 00:09:04.879 and that would be my hope, is that maybe we 192 00:09:05.080 --> 00:09:06.879 get the smoke up in a way so that they 193 00:09:06.879 --> 00:09:08.679 don't have to deal with the poor air quality and 194 00:09:08.679 --> 00:09:09.879 the smell. Uh. 195 00:09:09.960 --> 00:09:11.960 Dave Frasier, Joy as always, my friend. We'll talk to 196 00:09:12.039 --> 00:09:12.600 you next week. 197 00:09:13.440 --> 00:09:14.840 Yep. Have a great rest of your week. 198 00:09:14.960 --> 00:09:17.759 Huh you do? That is Dave Frasier from Fox thirty one.
