In this video we're going to do a severe weather statement to follow up our severe thunderstorm warning from the previous exercise. 

So the first thing I want you to do is double-click on the Cave clock on the bottom of the display and we're gonna change our minutes to 59. So just hold down the spin bar until it gets to 59 and click OK. I'm gonna go ahead and toggle off the local warnings. Because we've got some of the warnings from the the local CWA archive, and I just want to keep it simple here. So I want to force this display to update to 23:59 by just right clicking on the small pane over on the side. And then I can right click on the small pane again, and now my radar data is updated to 23:59 and we can have a little bit more context to update our severe weather statement. 

So the first thing we need to do with Warngen is select the severe weather statement checkbox. Once we've selected that then Warngen disappears for the moment. We can select the warning that we want to update from the follow up list. But we have to remember our etn number. Mine was 5010. Yours will be a different number so you have to remember that in order to select your warning to be able to update it. I have a choice right now to continue or cancel the warning and I want to continue the warning so I could select that. The second way that you can access this if you have the interactive Warngen is editable, then if you right-click in the location where you had a polygon it's gonna check and it's going to provide that to you in the follow-up list. So I have severe weather statement. Continue. My etn is 5010. I'm good to go. So I could have either just selected it from here or I could right-click on the location where the polygon was when Warngen is editable. 

Next, I want to go to the default settings that I have in here from my warning and I'm going to change them. I have a spotter report of baseball sized hail at 6:35. So I'm going to change my basis from radar-indicated to trained spotters reported. Leave the wind threat 60 miles an hour, and then change what had been two inches is now gonna be baseball sized hail. So if I had a two inch maximum expected size in my warning, and I expected that to continue, and I hadn't had any reports yet, but I did get in a report a quarter sized hail, then I would include the quarter sized hail and manually type that in and leave the two inch hail selected because it's less than my maximum expected threat. In this instance the baseball sized hail is larger than what we had in our previous warning. So we want that threat tag and bottom of the warning to say the maximum expected size, which in this case is going to be baseballs. Alright, so I have baseball sized hail selected. List of cities is how we had it set before. Calls to action: got the destructive hail there. I don't need my generic threat if I have the destructive hail selected. 

So after that I am just about ready to create my text. Only I need to update the motion and the polygon and where the threat area is. So let me step through my loop and see did I get my motion well done? If so then I shouldn't have to do anything. Looks like my storm is continuing to move along the same track. I don't need to change my track. But if I did, then I could just use the distance speed tool here to redo my track. It's gonna change the motion that's in the warning but I can't have the polygon increase in size. I can only decrease a severe thunderstorm warning with a with a severe weather statement. So I don't need to modify my track. I just need to adjust this to cover the threat area better. So Central High is definitely out of the warning by this time. And I see if I... if I do something like that, then this looks like a reasonable adjustment to my warning. The main hail threats kind of right in here, that's moving off to the northeast. You notice that all three of these counties are hatched. There's W's in each one them. So that means all three counties are going to continue. Now if I cut this really close, then I would have this sliver that is unhatched. And so what this is, is if there is... there's a certain percentage, it's an areal percentage that... it's customized at the local site. You can set how much of an area needs to be covered before it's going to be included in a warning. So we have fallen underneath that area threshold. And so it's going to exclude this county from the warnings. Basically gonna cancel this county, and it's gonna continue these two counties. Well right now, I want to keep this area in. So if you ever run into the circumstance where you've got a sliver that you want to keep in, then the only way to get that in is to keep adjusting the area size until it passes that area threshold, and then it gets hatched and put in. So I think there's a hail threat that goes all the way back there. So I'm gonna go ahead and include that area in my warning now. If you want you can tweak it out and then see what happens when the partial cancellation will happen automatically. You'll get one cancellation for eastern Comanche County and then continuation from these two counties. But I'm gonna leave it in and then we'll go from there. 

Alright, so we have all our stuff selected in here. We have our tracks fine. Our area has been modified some. If we tried to increase this in size you see that it's not gonna hatch anything else. And it will snap it back whenever we create our text. So I'm gonna go ahead and hit the create text button, after I need to make sure I have my text workstation up here. You should have yours up. I've got mine. So let's go ahead and hit create text. Gonna generate the product. See it snap that back, cause again, you can never expand a warning in a follow-up statement. You can only shrink it. So I get my AWIPS header block. Don't change anything. Just click enter. Get my severe weather statement locked code in blue. There's my etn, 5010. And I've got Comanche, Stephens, Grady counties in here. So at 6:59 p.m. Central Daylight Time, severe thunderstorm was located four miles west of Marlow moving northeast at 30. 

This is where we're gonna enter in the time of our spotter report. So this is the spotter report was at 6:35. So we're gonna say at 6:35 p.m. spotters reported baseball sized hail, five miles east southeast of Lawton. So we are going to include the time of the spotter report here because we have the radar time here 6:59. This is when we're updating the position of the storm. Was located four miles west of Marlow, moving northeast at 30. At 6:35 p.m. spotters reported baseball sized hail five miles east southeast of Lawton. We've got baseball sized hail, 60 mile-per-hour wind gusts in the hazard at the bottom. We have baseball sized hail and 60 mile an hour winds so we don't want to change any of this. Our source is trained weather spotters just like we had selected. So the whole idea behind a lot of these impact based warnings, a lot of this text taken care of for you. You're just adding some critical information on the front end like what's the maximum expected sizes? And then typing in the spotter report information such as the time in the product. So we just go ahead and click the send button. Click go ahead. And go ahead again. Now if I turn back on my polygon displays, I'm going to turn off Warngen. There is my new warning, my follow-up statement right there. 

So that is the basics of issuing a warning and a follow-up statement. I need to double click on the D2D. clock now, and we're gonna go back to 23:40 so we can continue on with our other exercise, because this is the only time that we've deviated from 23:40 for our exercises here. And now we'll be back to where we were. Swapped panes out. We'll go back to 23:37 and you can continue on with the next exercise.
