A Recipe For Destroying Myself...

Click here for a plot of all warnings.
Well, today was one of those perfect scenario, moderate risk days. However, I destroyed myself by making a few stupid mistakes. Starting out a bit late...around 2:30 PM CDT...I had my eye on an awesome looking storm on radar that just getting fired up north of the Enid, OK area. This storm was slithering its way ENE. Of course, being very eager to get going, I decided that would be our target...no questions about it. Leaving when we did, around 2:30 PM, would allow us to drive north on I-35 to the Ponca City/Kay County, OK area...where our storm would, hopefully, be fast approaching when we got there. I just had to have known, though, this tactic was going to fail... In the back of my mind I kept wondering about more intense storms possibly firing up in greater instability to the south. In this case, I should have contained my eagerness and listened to the back of my mind for once. Not more than 30 minutes after we hit the road, multiple supercells began to rapidly pop-up off of the dryline in west-central Oklahoma. Argh! By the time we were half way to Ponca City, we could begin to see the fast growing towers off to the southwest. Meanwhile, our original target storm continued to grow larger and more impressive in the windshield.

The question that presented itself at this time was, do we cut-out on an obviously impressive storm to back-track and try getting to whatever was SW of us, or keep going. The longer I thought about it, the closer we kept getting to the Kay County storm...which, unintentionally, made the decision easier with time. Kay County it was...even though the nagging second thoughts of going for the "tail-end Charlie" storms lingered.

Just as we started closing in on the storm from the S on I-35, awesome mammatus began streaming overhead on the underside of the storm's thick anvil. I snapped this picture while stopped at a Conoco somewhere between Stillwater and Blackwell... Lightning activity increased dramatically during this time as well. Then, just a few miles passed the exit to Blackwell, a very menacing looking precipitation core became visible off just to the north. Continuing to drive toward this gave me a rather bad feeling...especially considering that we had been hearing reports from NOAA Wx Radio of hail baseball sized and larger coming out of this storm a county or two back... Also, continuing to drive into the front-flank core from the south would likely mean that we had overshot our prime viewing location, by quiet a bit. Given those factors, the U-turn tactic was employed. We tried several routes in getting to the storm's updraft...but, for some reason, we just couldn't seem to find it. After, about twenty minutes of shifting around, we finally got into a good position inside the inflow notch, just SE of the apex of the front-flank and rear-flank downdrafts and the rain-free updraft.

The storm put on a good show. It had very nice "HP" supercell type structure and obvious rotation. But, by the time we reached the storm, it began to become very much outflow dominated...pretty much blowing its organization to bits. However, wanting to get something for my troubles, I hung with the storm way too long...squandering valuable daylight. It was during this time that we began to get reports of tornadoes in Kingfisher County. NO! Foiled again!

We drove around outside of Ponca City a bit, got some gas, and then decided to head back to OU...hopefully returning to OU before the storms hit Norman (as if storms ever hit Norman...right?!?). The trip home was quite something indeed... We drove through what seemed to be a solid line of supercells from near Billings all the way to back Norman. Luckily for us, we missed most of the hail with these storms. We got stuck in several blinding downpours, however.

During our trek home, the storm situation became quite interesting near Stillwater. Listening to reports on KOSU radio, we ascertained that a fairly significant area of rotation must have been approaching Stillwater from the west. We continued southward and finally broke out of the rain somewhat SW of Stillwater. With it being dark at the time, we used the extremely intense lightning as a guide. We stopped off and observed a lowered cloud base to the east-northeast produce a fair-looking funnel cloud as it moved toward Stillwater.

After that, we continued south. As we approached OKC we began to hear of tornado warnings for Grady and McClain counties to the SW of the metro. As we entered OKC, a tornado warning went out for Cleveland County. Yea! Again with chasing tornadoes at night... We continued plowing our way southward through heavy rain and small hail. Once in Moore, we began to break-out of the precipitation and saw a very ominous looking cloud base off to the west, illuminated by some of the most intense lightning I've ever witnessed. We finally arrived back at the dorms around 8:20 PM. We ran upstairs to our 8th floor TV lounge...which featured a large bay window with a great view to the north. Between 8:30 and 8:45 we observed a very pronounced lowering/funnel move from west to east across, what looked to be, the Moore area. Several intense power flashes occurred during this time. While we were unable to be 100% certain, I bet that what we saw was the Moore tornado in it's weakening stages...

Otherwise, the storm event ended with a squall line that rolled through early, EARLY the following morning. The next day, on my way to get pics developed at our favorite pic stop, the Wal-Green's at N. 12th Street and Santa Fe in Moore, I some fairly impressive damage brought on by the Moore tornado. Little did I know, not more than 5 months later, the same area, including our beloved Wal-Green's, would fall victim to one of the strongest tornadoes in Oklahoma history (more on that here).

The NWS in Norman has also put together a great summary of this event with relevant radar images, damage survey results, etc. Click here for that.
