May 10, 2008 Storm Chase Summary
May 11th, 2008 by Karen PolitteUnlike so many who got behind it on the south side, Jason and I decided to bust on the Stuttgart, AR storm in a new and unusual way. Actually, we busted on three separate tornado-warned storms within two hours. If that’s some sort of record, somebody please let me know.
Unsurprisingly, we chose the eastern AR target yesterday and avoided eastern OK/southeastern OK target like the plague due to the less than favorable chase terrain there.
Anyway, we left home around 11am and sat in north L.R. for the late morning and early afternoon. Saw Currens on Spotter Network blasting down I-40, LOL. Monitoring data and sitting on the north side of the warm front, we deemed it was best to head south to Pine Bluff and assess from there, as the high-CAPE air, sunshine, and cu fields were all down in that vicinity and at the time it looked like southern AR to southeastern AR may be the place to be. Arrived in Pine Bluff (a.k.a. the Armpit of Arkansas) at approx. 2.00PM, and sat up near the mall in their spacious parking lot for hours watching data. Took my compass out and stood in the middle of their parking lot watching our winds veer from southeasterly to southerly to southwesterly. Great. Our benign cu field stayed that way for the longest time, and Jason and I partook in a game of “catch the Mardi Gras beads” in the stiff southerly winds. I really need a Frisbee.
So 4PM came and went, the afternoon threatened to turn into evening, and our cu field began to dissipate. AR appeared to be under the influence of an upper level shortwave ridge, and was still pre-upper-support arriving. Meanwhile, there were thundershowers moving into north-central and west-central AR from some OK junk that rung our alarm bells and, considering that it was far more fruitful of an idea to head back north towards L.R., AND see “some” type of convection - we thankfully left Pine Bluff and headed back towards L.R. Halfway between Pine Bluff and L.R., while watching the thundershowers on radar closely (we’re all too familiar with what disorganized thundershowers can do in these parts), I had the opportunity to nowcast for Brian Emfinger, a fellow AR chaser, who was trying to grapple with the McAlester storms around that time they were going tornadic. Hopefully I helped out - if so, I at least came away something from yesterday.
Anyways - we got some gas in L.R., used the nastiest restroom I ever have, and sat up in the parking lot of the Clinton Library for an hour or so at 5PM. While gazing wistfully at the array of convection - both mushy and somewhat harder - exploding and dancing above my head, I spotted a really neat midlevel funnel backlit by the blue sky, which was extending from a tiny piece of ragged cu. We jumped out and Jason snatched some video. Pretty cool. After that excitement, we saw that an isolated area of harder convection to our northeast near Carlisle, AR was looking a bit stronger on radar - although not yet severe. Favoring this over the junk moving into west L.R., we headed east on I-40 to intercept this area of multicellular storms and see what it had.
Then things started to go downhill in a hurry.
Once we got to near Carlisle and realized that we had gained no ground on the storm driving at 75mph for approx. 30 minutes, and taken a look at GRL3 and realized that the (now severe-warned) southernmost storm of the mess that moved into western L.R. was now threatening to have an appendage (couple of profanities slipped out here), we cut loose from the storm we were pursuing which was now bearing down on wherever (I dunno - De Valls Bluff by now???) and doubled-back to target the southern L.R. storm which was looking quite threatening. Indeed, no sooner had we done this than a TOR was issued for it. And - no sooner had this happened than our entire laptop crashed due to a problem downloading a SpotterNetwork update. Every window froze, we lost our GPS fix and could not re-acquire, and GRL3 ceased updating. The machine wouldn’t even restart from windows, so I had to jam the power button down and forcefully make it switch OFF.
With no data and a blank laptop screen, we entered the northern extent of the two tornadic supercell’s cores around Lonoke. Blinding rain and intense CGs abound, along with terrified drivers slamming on their brakes led to us trying to thread our way into the city again. My nerves began to get a tad bit filed here, I must admit. At long, long last the laptop finally rebooted from the Welcome screen to the actual desktop, and we managed to bring up GRL3 again to see what was going on. Our GPS program would still not acquire a fix. What BS. The southernmost supercell moving across south L.R. was looking downright scary and was taking a fix on England sometime in the mid-future, and the initial lead rotating updraft had retained it’s supercellular characteristics and couplet and placed itself just east of our interest storm, leading to the NWS’s long, rectangular TOR box to cover all of the possible areas of rotation.
So there we were, with no GPS, skirting the north side of two tornadic supercells, unsure of what the hell we could - or wanted - to do. We pulled off at Exit 161 in blinding rain and small hail and went into the third round with our GPS software and finally got it working. But it was too little too late. Way back in Lonoke, where we had had a south road option, we should have taken it - right at the point our whole laptop croaked. The profanities came a little more fluently now in the Politte vehicle. Our tornadic supercells continued munching through the countryside to our south by about 15-20 miles at 55mph. We assessed. The only option that was realistic that would give us hope to witness the intensifying southernmost storm was to head south of where we were currently on 391 (Valentine Rd.) and try and thread the needle in-between the two hooks, placing ourselves just east of the most intense storm once breaking through.
We started our route south and immediately got blinded by torrential rain, small hail, and pretty high winds. Our road skirted “Faulkner Lake”, and not only did we have to worry about our situation w/r/t the storms, but we also had to worry about encountering flooding. Some low-lying areas of the road were already starting to get standing water on them. We travelled two miles down this road at 40mph in blinding conditions before I started to feel sick to my stomach and decided to initiate my “is this really a good idea?” sequence. We pulled off in some random piece of parking lot at god-knows-where and assessed again while the winds went crazy and the clouds above our rain raced northeast. Radar pretty much told us everything - it was hopeless. The strong tornadic storm was already almost due south of us, and also a new type of storm had been identified - the “Bodyguard Storm”. The supercell that had been east of the strongest one had slid - all the while retaining it’s strong-possibly-tornadic couplet - in above the main storm of interest, piggy-backing it. Two potentially tornadic couplets oriented in a N-S line doesn’t make for a very good intercept of the southernmost storm if you begin on the north side of the complex.
Weak.
So obviously we prized our lives more than the chase and abandoned the whole chase, opting to head north to the interstate again before we got ourselves into any sort of real trouble. The drive back north to I-40 was one of my less favored in several years, and we managed to “identify” or “sample” a circulation into the bargain as well. Strong north winds rushed into “something” behind us as we crawled north and passed many vehicles pulled off the road, the winds smashed into the trees on the side of our road, and then a second later we had westerly winds pushing the driven precip into the driver’s side of the vehicle. I only knew that we had come uncomfortably close (for me) to yet another one of those rain-wrapped *somethings* (just like on Dumas day last year). In retrospect, this may have been the developing circulation that went on to produce the “possible brief touchdown” mentioned in SPC’s logs as: 0020 2 E LONOKE LONOKE AR 3479 9186 POSSIBLE BRIEF TOUCHDOWN WAS REPORTED AT MILE MARKER 173 JUST SOUTH OF INTERSTATE 40. (LZK)
We got back to I-40 and assessed data again all the while noting that the storm to our east that we let go had gone TOR too. Two busts down - but we still had one left in us - and that was reserved for the Searcy TOR storm. We attempted to salvage something and blasted northeast on 167 towards this big, meaty SUP, and somewhere just east of Cabot it became obvious that this rocketing storm was also outwith our grasp, and we threw our hands up and gave in on the day.
Got back into Conway at about 9.00PM just in time to grab the worst burger I have ever had from our local Sonic, and collapse and watch our soccer team lose another game on television.
Frustrating day and very sad to hear of the loss of life and much damage that came from yesterday’s outbreak.
