Chase Case 12

  • Thread starter Thread starter Matt Gingery
  • Start date Start date
I'm a little late to the punch here, but I'll be starting in Beatrice, NE.
 
Am I the only one who is confused by the 12z time stamp? We're talking 7 a.m. CDT, right? But the satellite images look like the sun is high in the sky, and here's a line from MD #1: EARLY THIS AFTERNOON A SURFACE FRONT EXTENDS FROM CNTRL KS SSWWD
THROUGH WRN OK....

I'm seeing a progression in what the models are showing, but that 12z run time seems to be stuck in a time warp. Or am I?

EDIT: Notice that the Midwest satellite image shows a time stamp of 1815z. No doubt I'm betraying my ignorance here, but what am I missing?

Bob,it's the same thing I was thinking before! Probably the cell in southern Ks could be at 18Z...Maybe Matt can give us an help.
 
Sorry about the confusion. That is my fault. I went ahead and updated the last post to make it 12 & 18 Z information. Most of it is based on 18z, with the exception of some of the surface analysis. I was trying to hide the time stamps as much as possible, my bad. This is my first case, and I have tons of data in a folder and I mixed it up just a tad. Disregarding the time stamps etc., this will not effect anyones position, storms haven't quite innitiated yet, so get into position and there will be. . .

Hold it! I have something coming across the wire. . . .

Stand By (Emergency Tones********).

Just so everyone is aware. It isn't too late to jump into this virtual chase. The storms haven't popped yet, and everyone should be able to get into position between 18z and 21z. There will be supplemental updates between the 18z and 21z updates for any watches or MD's. This is my first run at one of these chase cases, so hang in there, I will be a professional when its all over. I was up til 4 a.m. last night collecting data and putting it together, there may be mistakes, and I appreciate you all bringing any to my attention. Happy Chasing All!!!!!
 
note to self: don't pick targets in the middle of the night without comprehending meaningful data. (I think I thought the surface map was a prediction for 0z or something -- I'm not sure ;) )

So I guess I'm enjoy the post frontal weather in, uhh, Dodge City...where I shall be taking off from immediately trying to get back in that watch box. (I was sleeping in -- that's the ticket) How about towards Salina. Bout three hours from here.

Well, I'm definitely leaving Springfield, MO. Have nothing but light rain and cloud cover. I'm liking the looks of the cell in KS near the OK/KS border. I'll head west towards Wichita and keep my eyes peeled for anything interesting. Perhaps the same storm will still be hangin' around when I get into KS and be worth looking at. It's a 4 hour trip, so I should be arriving in Wichita about 22Z. I'm certain something of interest will pop up between here and there though. I'm thinking 15Z info probably would have tipped me on heading west anyway, but since this is a virtual chase, I must admit my mistake of starting off so far east.

Yeah! LOL, you get a complimentary free beaming to the city of your choice. It only takes a few minutes, sit back and relax and pick the city of your choice based off the current and accurate data.:D
 
Waking early to catch the 12Z the progression of the surface low and moisture was such that it looked like I needed to be a bit farther north, but not so far I needed to get crazy. I left Independence, MO, for Council Bluffs, IA, and was fed, fueled, and ready to go when the 18Z data came in. I had just decided to get a little closer to the action suggested by the satellite images and relocate to Lincoln, NE, when the PDS watch came in. I'm off.... I want to stay close to the Interstates because storms will be moving a little north of east right along at 35 kts. or so and things may happen fast when they go.
 
Getting in on this one late and of course I'm going to be somewhere in that PDS tornado watch box. Looking at the latest surface features I will meet Dann out in Beatrice, NE as well!
 
Well with the data update that came in as we were moving through Wichita, we have decided to change course, and are now instead targeting Manhattan, KS. The upper-level system appears to have already ejected out of the Rocky Mountains based on the precipitation structure on the radar image associated with the Tornado Watch. There will probably not be much time to sit around and get more data once I get to Manhattan, though.
 
Time for a course adjustment. I just can't ignore a PDS. I'm making tracks for Lincoln, NE. I have an idea that Oakland, IA, where I was originally headed, will wind up under a watch box as well, but I want to be closer to where storms are likely to initiate.
