Storm Chasing May 8 and 9

On May 8th and 9th, a mid-level jet streak emerged into the Central Plains, triggering severe weather. Here are the storms that we saw. On Friday, May 8th, we tracked a supercell along the Red River Valley. We first intercepted it at the junction of US 183 and 287 east of Vernon, TX. This video is from while we are driving east on 287 near Harold, TX from 4:50-4:58 PM CDT:

This one is while we are driving north on 1739 and then east on 240 from 5:16-5:19 PM CDT:

We followed it into far southern Oklahoma, heading east on US 70. This is from just east of Randlett from 5:50-5:53 PM CDT.

The view from the junction of US 70 and 65 was had low contrast, but there was starting to be some good lightning. This was from 6:14-6:18 PM CDT:

From 6:31-6:41 PM CDT the structure had become impressive, there was more intense lightning, and the storm was producing a constant low rumbling sound. We are on US 70 west of Waurika and south of Hastings.

One more good view from Waurika, at the intersection of US 70 and US 81 from 6:54-6:59 PM CDT:

On May 9th, we caught a storm that had recently developed in the Texas Panhandle along a dry line, and moved into the Oklahoma Panhandle. We are on US 64 about 5 miles northeast of Beaver, east of Forgan, and east of highway 23. This is from 6:35-6:36 PM CDT on May 9, 2015:

These next three are from the same spot, at 6:45-6:46, 6:48, and 7:01-7:03 PM CDT:

This one is from a little further east on US 64 from 7:15-7:17 PM CDT:

The next video is from Kansas highway 34, north of US 160, northeast of Ashland, and west of Coldwater. This was from 8:26-8:27 PM CDT:

As we continued north on 34, the storm intensified. This was from 8:29-8:37 PM CDT, and towards the end of the video, we are nearing Bucklin and US 54:

At the beginning of the next video, we are at Bucklin, on Kansas highway 34, just south of US 54 seeing excellent storm structure. We then drive east on 54, then north from Mullinville. This was from 8:38-8:58 PM CDT:

The same synoptic scale system responsible for these storms also produced blizzard conditions in western South Dakota.

Rapid City received 13.6" of snow on May 9-10. And 24" fell at Fort Robinson, NE.

A frost advisory has been issued as far south as Hutchinson, KS tonight.
