Total Distance: 300 miles
Target Area: Clinton, OK
Chase Area: E. of Cordell to El Reno, OK
Maximum SPC Risk category: Moderate

Dan Dawson, Robin Tanamachi, Gabe Garfield, and I stayed primarily on the northern supercell from not long after initiation to sunset. We successfully played a "split the difference" deal for a while, with bases of both supercells in view, though we opted to stay closer to the northern storm given it's rather beautiful appearance at times. The structure of this storm seemed to improve nicely by about 8 pm, and a blocky wall cloud and tiered low-level structure developed shortly thereafter. Unfortunately for us, though, cell interaction with the supercell to the southwest proved detrimental to the storm we had been following. As such, as dropped south and east to get a spot southeast of Binger that provided a good view to the west. We saw rapid wall-cloud motion between Binger and Cogar not long after, and we measured a 51 kt (not 51 mph, as the LSR indicated) inflow wind a few miles W of Cogar as this 2nd supercell lifted northeastward. With a 3rd supercell to the immediate west, we jumped back towards Binger to get a better view, and we ended up following this one through Union City (were we saw 2" hail on the ground) before calling it a night (near 11:45 or midnight).

Target Area: Near Hobart, OK
Chase Area: S of Wichita Falls, TX
Maximum SPC Risk category: Moderate

Today was definitely a structure day, that's for sure. Dan Dawson, Howie Bluestein, and I made the trip southwest from OUN with an initial target of between Snyder and Hobart, OK. Upon seeing initiation W of SPS, we hedged a bit south, and sat in Lawton for a half an hour waiting to see any signs of life nearer the warm front. SFc maps at the time showed the low-level moisture mixing out across the DFW metroplex northwestward towards SPS, where Tds generally resided in the 55-59F range. Despite this, the only game in town was the triplet of cores W of SPS, so we darted southward towards Burkburnett.

Total Distance: 725 miles
Target Area: Around Abilene, TX
Chase Area: Cisco to Gainesville, TX
Maximum SPC Risk category: Moderate

Dan Dawson and I (with Robin Tanamachi and another following) were ~1 mi south of the meso SW of Breckenridge. I didn't see any full condensation, but the wrapping rain curtains were very impressive. We ran into downed tree and other minor tree damage ~6-7 mi SW of Breckenridge on FM 526 when we were just south of the meso. We then headed N on 183 and ran into a blown-over semi truck a few mi S of Breckenridge. RFD winds experienced were very strong. Power poles were blown down a couple miles S of 180, and the center of the rotation was reasonably apparent -- power poles snapped and laying to the W on the north side; power poles snapped and laying to the east on the south side.

Total Distance: 165 miles
Target Area: Broadly-defined (C through NE OK)
Chase Area: Guthrie to S of Pawnee, OK
Maximum SPC Risk category: Moderate

Howie B., Dan D., Robin T., Mike F. and I sat in Guthrie most of the afternoon as a hedge between an KS/OK border target and a central/southcentral OK play. By the time we saw convection go up SE of ICT, we determined that it was probably too late to try to catch up with it (figuring that the storms would be near Coffeyville by the time we got w/in view of it). So, we waited in hopes of initiation as much better low-level moisture (Tds 64-67F) worked northwestward across southern OK towards the OKC metro area.

Total Distance: 315 miles
Target Area: Near the Red River
Chase Area: Ringling to Durant, OK
Maximum SPC Risk category: Moderate

Didn't really expect a lot, but we chased a supercell that was quickly overcome by more widespread convection that developed in a relatively linear fashion. We ended up calling the chase off after it became apparent that discrete supercells were not going to happen. Oh yeah, it was nice to see some tornado reports from a cold-core sort of set-up near OKC. *rolls eyes*

Total Distance: 265 miles
Target Area: SE of OKC
Chase Area: Seminole to Henryetta, OK
Maximum SPC Risk category: Slight

First chase with all 3 radars saw mostly multicell convection that developed from W of Tulsa southwestward towards Purcell. We scanned from a parking lot in Seminole for a while before we noticed a lowering that looked suspiciously like a wall cloud to our NW. We headed N to I40, then eastward as the lowering persisted. Subsequent radar data from KTLX showed that a supercell was maturing within the larger convective line. A wet RFD soon developed just N of I40 W of Okemah, and we found a deployment location a couple miles N of Okemah as the mesocyclone occluded. The data are quite interesting given the proximity of the occlusion to our location (within a mile or two). We followed the storm eastward to Henryetta before sunset and before turning around to head back to OKC.

Total Distance: 450 miles
Target Area: Dodge City to Ness City, KS
Chase Area: Around Coldwater, KS
Maximum SPC Risk category: High

One deployment (IIRC) on an LP supercell approximately 2 mi N of the OK/KS border on Hwy 1 (or approximately 16 mi S of Coldwater, KS). The supercell passed from southwest through N/NE at a relatively close distance. A tornado warning was issued for this cell as it passed by to our northwest, but it dissipated rather rapidly when it passed our longitude (to our N). We ended up staying the night in Great Bend, KS. Big supercells and several large tornadoes occurred just S of I70 in northwestern Kansas, but we weren't able to make it that far northwest given our departure time from Norman.

Total Distance: 365 miles
Target Area: Near Ness City
Chase Area: Wakeeney to Ness City to Hays
Maximum SPC Risk category: Moderate

We probably have 3-5 tornadoes in our data, despite not seeing a single one. Road options were abysmal, as all of the non-paved roads were mud disasters. As such, it was extraordinarily difficult to get in position. At any rate, here's what we did:

Total Distance: 230 miles
Target Area: Near Pratt, KS
Chase Area: Clear sky bust
Maximum SPC Risk category: Slight

Frustrating day! We sat in PTT awaiting convective initiation along a dryline and near an outflow boundary from overnight convection. Well, we sat. And sat. Meanwhile, a couple of supercells anchored themselves along the southern portion of the outflow boundary between OKC and Enid. The second supercell produced numerous tornadoes, all while we sat in PTT thinking that we couldn't make it down there in time. Flow aloft was weak, but perhaps it's good that it was weak as it may have allowed the storm to anchor on the OFB without being advected further into the cold air. Regardless, we headed N through HYS in a last ditch attempt to catch TCus that were developed between I70 and the KS/NE border. In time, though, these attempts failed, and we stayed the night in GBD.

Total Distance: 260 miles
Target Area: Ness City, KS
Chase Area: Ransom to N of Great Bend, KS
Maximum SPC Risk category: Moderate

We had 3 deployments:1) NW of Ness City -- previously-tornadic supercell weakened as storms developed to the immediate S and SE of the storm. We scanned for 10 minutes. We dropped this (these) storm(s) to head to a new supercell that rapidly developed to our ESE/SE.2) S of Hays / E of La Crosse / W of Hoisington -- tornadic supercell to our NW through N, then another supercell went up to the immediate WSW of the former. Very nice wall cloud and at least one reported "tornado", but pictures showed it was a dust whirl under a lowering (perhaps a gustnado). Another couple of pictures showed what looked to be gustnadoes or perhaps landspouts. Total deployment time was 30+ minutes. The latter supercell had at least one nice occlusion, with a "hammerhead" hook that wrapped completely around into a donut hole. A tight couplet was noted on velocity data to our NW (~15 km). Visually, the storms became progressively more outflow-dominant. When the 2nd supercell moved east of longitude, we headed back E and N to redeploy.3) NW of Hoisington -- Brief deployment as the cells started to gust out. Meso should have been to our west at the very start of the data collection, but we were hit by cold outflow a minute or two after deployment. Rain and hail followed as the cold pool surged southward and undercut the updraft. Total deployment time of 10-15 minutes.

Target Area: Dodge City to Great Bend
Chase Area: Larned to Pratt to Belle Plaine

Yet another frustrating day to cap off a frustrating stretch of days. We deployed thrice today:

1) 14 mi of W of Larned -- intensifying convection that became increasingly outflow dominant. Large hail was reported to our west.

Total Distance: 1010 miles
Target Area: Near the KS/NE border
Chase Area: Kearney, NE, to Beloit, KS, to Belleville, KS
Maximum SPC Risk category: Moderate

Finally an awesome chase! Dan Dawson, Robin Tanamachi, and I (along with a couple others) made it to the Kearny area in time to witness at least one tornado on the SW side of town. We saw one large occlusion well SW of town, with good RFD motion and a gustnado. As we Hwy 44 two miles S of I80, a very rapid RFD punch occurred, followed by tornadogenesis to our immediate N. This tornado appeared to move N into rain, but there were at least a couple other tornado-like lowerings that we caught glimpses of through trees. We followed this cell as it became an HP mess to near Grand Island, at which time we decided it wasn't really worth chasing.

Total Distance: 255 miles
Target Area: Tonkawa, OK
Chase Area: Osage County, OK
Maximum SPC Risk category: Moderate

Junkus convectus. Intermittent supercells and multi-cells developed just E of I35 in far northern Oklahoma, but they failed to realized the max surface-based instability. We waited at the Tonkawa exit along I35 for a few hours before blasting ENE to developing convection in western Osage Co. We made it to near Skiatook (N of Tulsa) before turning around as the storms rapidly dissipated. The lowlight of the chase was watching the impressive supercells (right- and left-splits) W and NW of OKC on radar on our way home.

Total Distance: 270 miles
Target Area: Near Wichita, KS
Chase Area: Near Medicine Lodge, KS
Maximum SPC Risk category: Slight

Not much to report... Left w/ the W-band radar truck towards S KS, making the decision to head W towards the GUY supercell as opposed to northeastward towards EMP. We got to P28 in time to notice the HP supercell to our SW begin to gust/bow out, so we called it off and headed to GBD for the night.

Total Distance: 440 miles
Target Area: Red Cloud, NE, to Osbourne, KS
Chase Area: Near Kearney, KS
Maximum SPC Risk category: Moderate

We awoke in GBD from the previous chase, and it looked like the area between I70 and the NE/KS border would be game this day. We meandered northward with time as hot 700mb air slowly advected northward and capped off the areas of central and northern Kansas. Widespread convection developed near and just N of I80 in NE, and this convection spewed out a lot of cold outflow that undercut the rest of the convection. We passed north of the OFB SE of Holdrege and witness an undercut supercell S of Kearney. This supercell actually had some structure (RFD, good rain-free base, etc), but it was definitely undercut by a shallow cold pool. This cell actually produced a brief funnel S of Kearney. Regardless, we were already north of our target and knew nothing tornadic would come of the undercut storms, so we called the chase off and headed to SLN for the night. We arrived in SLN after midnight in extremely windy conditions. Never have I felt gradient winds that strong at midnight!

Total Distance: 400 miles
Target Area: Ill-defined
Chase Area: Ellsworth, KS, to Blackwell, OK
Maximum SPC Risk category: High

We "intercepted" severe embedded HP supercells and assorted thunderstorms from NE of Great Bend to S of Wichita between 1 pm and 7:30 pm, hoping southward for the next storm as we watched the nearest one fly by at speeds that would be fast for March and April.

Total Distance: 490 miles
Target Area: Condcordia, KS
Chase Area: Concordia to Salina to Carlton, KS
Maximum SPC Risk category: Moderate

Waited in Concordia, KS, for several hours awaiting initiation to our north through southwest. Several TCus and small Cbs developed and quickly weakened through mid-afternoon, before a relatively persistent supercell approached Concordia from the southwest (on the northeast side of a larger mass of convection that extended down towards Great Bend). We had a great view of a good rain-free base and strong RFD punch (and subsequent meso occlusion) just S of Concordia. As this cell tried to cycle back up again SE of CNK, it became apparent that it was weakening rather quickly. Seeing a very intense supercell SW of Salina at the time, we opted to ditch the weakening cell and hope to get a glimpse of the SLN supercell.

Total Distance: 440 miles
Target Area: N of Wichita, KS
Chase Area: Strong City to Emporia to Wichita to Rose Hill, KS
Maximum SPC Risk category: Slight

We witness a few supercells, largely embedded within a larger convective mess, to the NW of the Kansas Turnpike between ICT and SLN. We saw a few wall-clouds and RFD punches, but we didn't see any tornadoes. We were making our way to the tail-end charlie activity near Athony, KS, when a cell near us (W of Haysville; immediately SW of ICT) rapidly organized into a supercell. We tried to deploy the W-band in a good parking lot W of Haysville, but the lightning was extremely intense. Wrapping rain-curtains soon developed to our immediate south and southeast as we tried to get ahead of the storm, but we opted to let the occlusion occur to our east (we were in N winds on the west side of the meso) in light of safety issues that we'd incur if we wanted to punch through the hook at the same time it was occluding. We eventually felt safe enough to cut through the hook and got a good view of the storm again near Rose Hill (ESE of ICT). It was also apparent at this time, however, that the storm was throwing out an OFB that well undercut the rain-free base. Since the tornado potential seemed to be nil with this undercut storm, we headed to Wellington to get dinner. One last supercell moved to our north, but it was well after dark, so we let it slip by.

Target Area: Clinton to Hobart, OK
Chase Area: Hobart to south of Vernon, TX
Maximum SPC Risk category: Slight

I'm stealing this from Dan Dawson's chase report, since he was in my car (and, thus, we saw the same things):

We saw the same two supercells as the CoD crew, and indeed saw them a couple of times (along with another chase tour group that I was too far away from to identify). Jeff, Gabe, some others, and I headed west from Norman in mid-afternoon. We initially targeted the easternmost supercell, heading west on 152. To stay ahead of it, we had to drop south to Fort Cobb and head back west on 9. About this time, it was clear that this storm was dead, as no updraft base was visible, so we kept going west to the formerly tornado-warned supercell near Hobart.
