Storm Chase 2017 - Day 9 Thursday 18th May

Started the day in Woodward with a general chase target of NW to Northern Oklahoma and maybe SW & S Central Kansas. After sitting north of Woodward we punched through some torjado warned cores near Freedom to an isolated Supercell near Chester and punched east through the top of the storm which already had a large wedge to our south, after stopping and looking back the structure was jaw dropping on this spinning mesocyclone of the Supercell. A wedge was ongoing so we went back to Boise Junction and watched a small tornado skip across the road in front of us and then watched the main Wedge Touch down again over open fields between Boise Junction and Waynoka. Fortunately the tornado lifted as it the meso went over the town of Waynoka. Followed the storm through Waynoka and Alva before leaving the storm when it went HP. We then dropped down to the 2 Dryline Storms moving east and were treated to incredible Supercell structure before sunset. Ended the day in Enid and celebrated 2 more Oklahoma Tornadoes that did not impact anyone today. 8 for the trip with 1 day left.

Storm Chase 2017 - Day 8 Wednesday 17th May

Travel day from Lawton to Woodward in Oklahoma to get in position for a big severe day on Thursday. Stopped at a nice Diner called Lucille's Roadhouse for lunch.

Storm Chase 2017 - Day 7 Tuesday 16th May

Today the SPC gave a Moderate Risk of severe weather, with a 15% tornado risk, over the eastern Texas Panhandle and western Oklahoma.


From our overnight stay in Dumas, we headed SE to Shamrock to grab some lunch and position for storms expected to develop along the dryline in the eastern Texas Panhandle. Sure enough, storms developed mid-afternoon to our west and we intercepted a supercell mesocyclone/ rotating wall cloud which then dropped a tornado near McLean, TX, although we saw it in the distance, wet dirt tracks held us back from getting closer to get good photos and video of it.




We then blasted NE once off the dirt track to follow this supercell which then went on to drop a wedge tornado over Wheeler, TX.

We left this storm then dropped SE into western Oklahoma - where we intercepted another supercell near Erick, moving up from the SW. We had to core punch to storm on the I-40 east, pummelled by golf ball and a few soft ball size hail stones, cars and lorries were hiding under bridges, which made it treacherous. We came off the interstate near Elk City, OK and went south of town where came out the rain and hail and we were greeted by wedge tornado which we stopped just short of, though got hit by strong RFD briefly. Unfortunately, there were a few fatalities in Elk City from this tornado. So a close shave for us.

Followed this tornado warned supercell NE for a bit before deciding to leave it at Clinton, OK. Dropped south along the western side of another supercell moving up from the SW to watch the lightning which was ramping up as the light faded. Then blasted SE to our overnight stay in Lawton, south/central Oklahoma to stay overnight. Watched a squall line along the cold front roll through Lawton, which produced a good lightning show.

A hard and frustrating day, particularly not getting close to the McLean tornado, core puching 3 inch hail, and a close shave with a wedge tornado, but we saw 3 tornadoes and some amazing lightning.

Storm Chase 2017 - Day 6 Monday 15th May

3rd night in Amarillo at the same Super 8 Hotel, don't think I've stayed in the same place for so long. Anyway, same area as Sunday really for storms developing along dryline moving east, though a higher risk of severe weather with more moisture/CAPE meaning some large hail likely as well as strong wind gusts.

Stopped at Groom to east of Amarillo at the Cross of Jesus Christ Ministry to watch the cloud bubble up along the dryline to our west.

Eventually this convection broke the cap and severe-warned storms were developing early evening from Amarillo northwards and tracking NE. We intercepted a batch of supercells neat Stinnett in the eastern texas Panhandle NE of Amarillo, we saw all three types of supercell surround us: Classic, LP (Low Precipitation) and HP (High Precipitation). A classic-type supercell on the southern end of this mass of severe-warned storms had a rotating wall cloud for a time an dropped a funnel briefly. The lightning started cranking up too as the light was fading.

We found some large hail by th road side north of Stinnett.

Finished the day with Pizza and overnight stay in Dumas, Texas.

Storm Chase 2017 - Day 5 Sunday 14th May

A marginal risk of severe weather today, played with some storms over the eastern Texas Panhandle, saw a bit of lightning and sat through a dusty outflow surge - where tour leader Paul Botten may have thought twice about getting out the car to have a cigarette - the outflow winds were gusting to 65 mph, which incidentally snapped a power pole down the road.

But what was most special about today was the amazing display of mammatus on the back of these storms that we following as the sun set.

Storm Chase 2017 - Day 4 Saturday 13th May

Some days there are no storms in the Plains, so Saturday was a day of sight-seeing, and what better place to go than stunnng canyon in the Texas Panhandle. Storms return to the area Sunday.


Storm Chase 2017 - Day 3 Friday 12th May

Upper ridge building in today behind the system moving east bring recent days storms means no storms to chase on Friday, so travel Day to Amarillo in the Texas Panhandle - to position for possible storms on Sunday. We all went to the Big Texan restaurant, home of the 72oz steak, but no one was up for eating this steak, which you get free if you eat it along with a starter, sides and pudding in one hour on a stage in front of the whole restaurant.
Limo from our hotel to the Big Texan

Storm Chase 2017 - Day 2 Thurs 11th May

Today had another enhanced risk with 5% tornado probability, this time over NE Oklahoma.


Started off from Witchita Falls, our overnight stay in NW Texas, headed northeast to Oklahoma City then just north of the city up the I-35 to stop for lunch. A severe-warned storm was already over Okarche to the west of our stop for lunch, so we then moved to intercept it to the west of Guthrie. We saw a small funnel briefly poke down then we followed the storm back east through Guthrie, but had to drive through the hail core, where we got pummelled by golf-ball sized hail as arrived at the interstate intersection just outside the town.
We then continued to follow the storm east stair stepping along roads east of I-35, having to go through the heavy rain and hail core to get ahead of it, buffeted by very strong outflow winds too.

Storm Chase 2017 - Day 1 Weds 10th May

Left Childress, where we stayed overnight, after lunch and headed south to intercept a supercell coming off the Cap Rock Escarpment to the NW of Paducah. Followed it north for rest of the afternoon before shaking it off in southern Oklahoma then dropping back south in Texas near Chillicothe on Hwy 287 to watch a storm developing further south on 'tail-end charlie'. This had a solid updraft and signs of strong inflow and meso. Followed it north into Oklahoma where we got cored by golf ball-sized hail as we hooped over the Red River. Ccame of the hail core then went back to storm under the hook on radar - where we intercepted a weak tornado crossing the road.

Storm Chase May 2017 - Bonus Chase Day

Most of the folks on tour 1 of this year's Netweather Chase departed our first overnight stay near DFW airport for a bonus chase day before the first scheduled chase day tomorrow. However, Oliver Ewers and I have taken one for the team and have decided to stay at the hotel to wait for the final guest to arrive on his flight this afternoon while the rest of the guests go in the 2 cars to western Texas as a target to chase the Enhanced Risk (with 10% tornado risk) that will develop there and over eastern New Mexico in the afternoon.



So I will drive with Oli over to the airport to pick up the last guest who lands between 3-4pm, then drive up highway 287 to Childress, which is a bout 3 1/2 hour drive, to wait for the rest of the team to come over from their day's chasing further west. So good luck for those on the bonus chase today, I will post some picks from them later.

Here's the beast I will be driving, GMC Yukon, FBI style

Storm Chase May 2017 - Tornado Alley Here I Come

Flying from Heathrow to Dallas on Monday 8th May 2017, landing early evening. I will be one of three drivers on tour 1 of the Netweather Storm Chase in 2017. First chase day proper will be Wednesday 10th May and will not have too far to go for chase opportunities.

A storm system or upper low will move east from California over the SW deserts and emerge over the southern Plains by mid-week. The cooling mid-levels as the upper low approaches atop a warm moist southerly surface flow that has been in place for several days will generate strong surface-based instability with surface heating. The strengthening SWly flow aloft ahead of the approaching low from the west and backed surface flow will generate sufficient wind shear for supercells that will likely form along a dry line mixing east from New Mexico on Tuesday and Wednesday.



The Storm Prediction Centre day 3 has a Marginal Risk of severe storms on Tuesday across eastern NM, western TX, eastern CO - but we won't make this risk. But as of Sunday's 4-8 day outlook already have a 15% risk area just NW of Dallas Metroplex across NW Texas and western Oklahoma on Wednesday. Then on Thursday the risk shifts east with the eastward-moving low pressure system, with far NE texas, far SE Oklahoma and much of Arkansas under the gun on SPC day 5 outlook 15% risk area.

 



So once the last guest has landed Tuesday afternoon, I think the plan is head NW up highway 287 (or referred by some chasers as the Highway to Heaven!) and perhaps stay somewhere like Witchita Falls in NW Texas. We are then in the general area for Wednesday severe storm risk, though the area of best potential may change a bit by then, but SPC mention 'all severe hazards' which includes tornadoes, but I will look more closely on the potential nearer the time. Then I guess we'll be heading east for Thursday towards or into Arkansas for the severe storm risk.

Beyond Thursday, the severe storms will shift further east still, perhaps east of the Mississippi River across the Dixie States (LA, MS,AL,GA) - but this will probably be too far east to go for us, bearing in mind subsequent risks over the weekend may develop way to the northwest over the central and northern High Plains - as the next upper trough arrives over the Mountain West from the Pacific weekend of the 13/14th and early following week commencing 15th.

CIAO for now, and talk again once I'm state side.
