Splendid Storm and Sunset near Hot Springs SD
14 June 11
SHORT: Began in Kimball. High-based storms and shallow convection along way N to Hot Springs SD. Beautiful storm before sunset over Wind Cave NP followed by equally amazing sunset scenes there.
LONG:
This wasn’t intended to be a “chase day”, per se, but we nonetheless encountered some beautiful shallow-convective scenery enroute that make it well worth sharing here, capped off by a wonderful little storm and color-splashed sunset where the Black Hills meet the Great Plains. On this day, the convection came to us!
After a decent brunch in IBM, we took off N for a couple of nights in a familiar set of cabins at Hot Springs. Along the way, we photographed an abandoned performance hall against a backdrop of brilliant, post-frontal blue sky and deep cumuli. The old place, structurally sound but superficially rickety, had a stage, piano, ticket booth, and separate outdoor latrine. Imagine having to leave the performance because of a terrible need to take a big dump…everyone there would know!
Sufficient residual moisture and relatively cold air aloft supported convectively textured, yet very clean, post-frontal skies that made fine backdrops for photographing other abandoned structures, such as this one near Crawford and this one near the NEb/SD border. The sky also added richness to scenes of rock formations, patterns, flowers and landscapes in the Toadstool Geologic Park within Oglala National Grassland. Toadstool is a wondrous little favorite place for us on the Great Plains–an outpost of the Badlands without all the tourist crowds–where we spent a few hours hiking and exploring for the first time in several years.
We got dinner in Hot Springs, whereupon my son David called to inform me he was caught driving in a tremendous hailstorm in Norman and needed advice on what to do. I directed him to a parking area; but his vehicle later got damaged by a flying tree limb in the second downburst. Facebook soon sprang to life with frantic posts of the fury of the hail-filled downbursts upon Norman. Ultimately, we would need to replace a good deal of roofing and guttering on our house from this event; and I knew even then that I would have many limbs to saw up and drag to the curb upon return. The dread of that chore made me enjoy this vacation even more, far away from still another Norman maelstrom that struck in our absence.
After dinner, we secured our cabin overlooking town, then headed up the road toward the rolling grasslands of Wind Cave National Park in hopes of some buffalo, wildflowers and sunset. Elke and I long have wanted to photograph a beautiful storm in the uniquely beautiful setting of this place…lo and behold! There it was! As we approached, we saw a growing Cb, cruising ESE across the undulating green carpet. One of our favorite overlooks happened to offer an outstanding view of the brilliantly lit storm. There we stayed, intermittent rumbles of thunder competing with the western meadowlarks for our ear, warm inflow at our backs, and before our eyes, among the most astounding non-severe stormscapes I’ve witnessed. The storm receded to the NE then E, letting the deep blue post-frontal sky into our wide-angle view, offering a source of reflected eastern light. We had begun full-sensory bathing in yet another transcendent experience best described by what Gretel Ehrlich once declared “the solace of open spaces”.
Just when we thought things couldn’t get more beautiful, they did, in a three-act production set across the theater of the sky. First, our storm gained a dense little core festooned with a bright rainbow that, after swapping on a zoom lens, made a postcard-pretty landscape scene for the national park. Right as that storm receded across the distant Badlands and weakened, the southwestern sky lit up with golden fractus basking in the sunset glow. As soon as those clouds began to dissipate, a couple of small virga showers formed to the S, dropping their wispy mists into the deepening red-orange hues. As they moved east, the moonrise beneath made for one of my favorite sunset and twilight shots of the year: flaming red virga beneath a golden crowned convective cloud top and blue sky. Finally, even as those colors faded, the western sky briefly blazed with a red-gilded cloud edge.
So concluded an unexpectedly stunning and soul-soothing display of atmospheric artistry! Before leaving the hilly meadow, however, there was one more piece of business to attend. On this evening, even a turd could spawn beauty, in this case a buffalo cookie supporting a mushroom! We would return the next day for some wildlife and flower photography and a visit to Crazy Horse, before resuming what would become the most active storm-observing vacation of our lives to date…
High Plains Lightning Festival
Colorado-Nebraska Border Region
13 June 11
SHORT: Began in BFF. Waited in SNY. Avoided outflow-surfing CO/NEb border storms to intercept supercell near AKO, saw probably non-tornadic dust whirls with storm merger there. Fantastic twilight lightning display from elevated storms along border S of IBM.
LONG:
Elke and I started the day in BFF, targeting the general area of the CO/NEb border SE of there. I wasn’t particularly jazzed by the weak lower-tropospheric winds in the forecast, figuring outflow and/or storm splits would be a problem. Still, it’s the high plains in early June with adequate moisture, upslope flow and at least marginal shear. The answer? Be there.
We waited a good, long time at a hilltop outside SNY, just NW of a dryline that eventually would fire up a tornadic HP supercell in the horrible road network and terrain of the Sandhills. We saw those towers to the distant NE, but chose not to pursue given the great difficulties involved with storm intercepts in those parts.
Meanwhile, we listened to meadowlarks and, on radar displays, watched chaser icons on SpotterNetwork zigzag back and forth across the area in impatience as the lack of focused action. Fuzzy storms began to fire between the Laramie Range and Cheyenne Ridge, which was no surprise; their distant bases were so high we could see them from SNY. I wasn’t impressed. Red dots converged on I-80 and headed W. We sat, waiting and hoping instead for dryline development to access richer moisture to our SE and E.
Finally, off to the distant SW, two storms erupted near and N of the Palmer Divide in Colorado. This was near the very southern fringes of our forecast area; but as nothing much was happening with the dryline nearby, and the storms were reachable, we decided to go have a look. Along the way SW, through the convoluted maze of roads that is Sterling CO, the southeast storm attracted quite a few chaser icons. The NW storm didn’t, was closer, and was in a similar environment; so we headed toward AKO to intercept it.
Alas, along the way, the SE storm calved off a big left-mover and died! Moreover, the left mover shot toward the inflow region of our target storm like a torpedo hell-bent on mutually assured destruction of both storms. Briefly, we got a view of the NW supercell’s mesocyclone area to our WSW before the left-mover’s core arrived; and it looked like a somewhat higher-based version of a North Texas HP “Stormzilla”. This meant big hail; so it was imperative to get S fast.
Yet there loomed the left-mover over the road to our S, likely bearing ice bombs also. It got there as we did, just S of AKO. The two storms started to merge overhead, and in the tiny gap between their cores, two strongly rotating dust whirls appeared less than a mile to our W, about 3 minutes apart. [I was driving and driving hard, so…no photos!]
Though a narrow, ribbon-shaped updraft had formed overhead at the merger location, we could see no obvious rotation in it. I attributed the whirls to gustnado-like vortices being stretched where the two gust fronts met. We maintained an equatorward bearing, encountering only marginal severe hail at best (to our relief).
Arriving just S of the combined storms, which indeed were killing each other, we photographed the dying supercell across rain-drenched corn stubble S of AKO. It was good to see Steve Hodanish and to swap Hodo stories with a co-worker of his, and also, to talk with a few other friendly storm observers whom I hadn’t met before. Yet we were essentially stormless, parting ways and headed back toward our various bases for the night. All that was left, for now, was outflow spinning a windmill under a dark and stormy high plains skyscape.
We headed toward lodging in the Nebraska Panhandle, soaking in the sights of Pawnee National Grasslands in anticipation of spending a couple of upcoming non-chase days of roaming around some of our favorite haunts around the Black Hills, not counting on any more atmospheric excitement. As good fortune sometimes plays on previously under-performing storm days, the night brought about an unexpected–and most welcome–show of splendor that made our night!
A short line of elevated and high-based thunderstorms erupted over the WY-NEb border region atop the outflow pool from all the late-afternoon activity, and moved SE across the southwestern Panhandle and across the Cheyenne Ridge. Evening storms like this in the High Plains can spark profusely, and these absolutely did! We found a vantage just over the CO/NEb border S of IBM (Kimball, not the company) and began shooting away at the approaching spectacle. Assorted forked and in-cloud displays slashed across the fading twilight, their reports blasting resonantly across the wide-open landscape. Soon, some cloud-to-air discharges flickered forth, followed by yet more (and closer) sky-splitting CG action. Wow…what a show!
The lightning was getting too close, though; so we drove through the translucent core of the thunderstorm line a short distance into IBM, crossing a few miles of small hail (with almost no rain!) along the way. I’ll never forget the sight of countless thousands of little white hail balls in the high beams–cascading dots of brightness, the only form of light shining back at me along that dark High Plains highway.
After securing a motel room near the edge of town (like we like to do), we noticed the sparkling display still underway to our SE, and headed back out past the E edge of town for a little crawler-lightning show in the trailing precip region. And with a few more flashes to light up the midnight hour across the western Nebraska prairie, bedtime drew nigh, our storm-hungry palates duly satiated. I had very few lightning photos to show for 2011 until this night, when the heavens unloaded electrical gifts one after another in a most dazzling and appreciated fashion.
A Championship Day (Even if Not for Storms)
High-based Storms in the Nebraska Panhandle
12 June 11
SHORT: From LBL, headed to the BFF area for high-based upslope action. Observed a few such storms from between BFF-AIA.
LONG:
The day wasn’t too spectacular convectively, but we saw storms and had a great time nonetheless.
Morning dawned to the analytic display of foci that were somewhere between muddy, nebulous and vague on the spectrum of precision. The surface map showed that the isodrosothermal field had been mangled by overnight and morning convection over southern Kansas, east of where we spent the night. When all else fails, the terrain just isn’t going anywhere–at least not for the next 20-30 million years or so.
We therefore headed toward the reachable area of the NEb Panhandle/NE CO, figuring that 50s F dew points in that area sometimes do good things as long as deep-layer shear is at least marginal. It also put us in position for day-2. Plus, Elke and I love that area for many nonconvective reasons.
After visiting an abandoned shack in western KS, we found a nice hilltop vantage about 5 SW Angora NEb, listening to assorted birds and photographing wildflowers (e.g., copper mallow, western wallflower, and veiny dock), as we waited for convective eruptions.
Assorted towers and turrets soon bubbled up to the W and SW. One persistent pile to our W evolved into a short-lived, high-based storm with a wall cloud to our NW, viewed across the rippled orographic musculature of the Nebraska Panhandle’s ash-bed grasslands. The storm exhibited weak cyclonic shear in the midlevels based on radar velocity output, but just for a few scans.
Other, smaller, junkier cells fired along the foothills in SE WY and over the western reaches of the Wildcat Hills to our SW, amounting to little except as a scenic diversion for aviators. We saw several contrails weaving between storms, including this scene over Minatare. The storms died off with the setting sun.
We settled into a charming little mom-n-pop motel in BFF with funky walls made of green quartzite from Utah. This also was the memorable night my hometown Dallas Mavericks won the NBA championship too–making up for a disappointing evening 5 years before in GCK when I watched them lose it to the very same team.
A very fine day, indeed…
