June 14th Lincoln, Nebraska Nocturnal Tornadic Supercell

We weren’t expecting much on June 14th. Things were mistimed, moisture was iffy and instability lacking. Storms eventually fired early evening towards Grand Island along a front and moved eastward. They started out high based and lowered as the temp/dew point spreads lessened. West of Lincoln by mid evening, a supercell emerged and started really rotating strongly. A tornado warning was issued as the storm moved east and developed a strong couplet. (An EF3 tornado was confirmed later!) As the storm approached the north side of Lincoln, it wrapped in rain and was a very dangerous supercell. You couldn’t see what was going on in the notch and we didn’t dare go north without an escape route to look down the notch. We had to let it go due to timing and lack of roads. It moved east and recycled again becoming tornado warned. Some damage was recorded east of Lincoln, but at the time of this writing it was not confirmed whether it was tornadic or RFD winds.  Certainly a surprise event and thankfully no fatalities occurred!

May 9th Wynnewood and Sulphur, Oklahoma Violent Tornadoes

May 9th was one of the best days of 2016. Deep moisture, high CAPE values, great wind shear and strong lift along a dryline would generate several intense and tornadic supercells in central and southern Oklahoma.  We positioned ourselves south of Pauls Valley as a persistent updraft was forming to our southwest. One supercell formed and anchored there and became tornado warned. However, it was the new updraft on its southern flank that would become the storm of the day. This updraft would become an intense tornadic supercell dropping an EF4, and 2 EF3 tornadoes along its path.

Our intercept of the very close and INTENSE EF4 Wynnewood tornado would be one our guests will never forget. A very predictable and fairly stable tornado would allow us to get very close to it, something we usually do on our Close Encounters tour. We were positioned a couple hundred yards north of the path of this tornado, and we flipped the vans around, ready to jump in and get out of the way should it make a sudden turn. It did not. It passed very close to us. You could hear the waterfall sound of the tornado as it ripped its way across the highway next to us. It would move east and dissipate near I-35. But this storm was far from done. A nearly mile wide tornado would develop and pass just north of Sulphur and an additional elephant trunk shaped tornado would form east.  Both of these tornadoes were rated EF3.  At the end of the day we would drop all the way south of the Red River into northern Texas as more supercells would develop and become tornado warned.

Our hearts go out to those who suffered losses this day.
