Our group was in pretty good shape position-wise as we gathered for the morning briefing at the motel in Chadron. \u00a0We had some time to allow Chuck to give a presentation, and then we enjoyed a fast-food lunch in town. \u00a0SPC put most of the Nebraska Panhandle in a slight risk area, which also covered most of the Dakotas. \u00a0I felt that our best prospects would be nearby, with convection developing not too far to our west and then drifting east during the afternoon. \u00a0Tornado prospects were low, but shear and instability values were very good for rotating updrafts.<\/p>\n

In the early afternoon, SPC circled the NE Panhandle and southeastern WY and shared their thoughts regarding severe weather potential:<\/p>\n

I was not inclined to go after the typical and early high-based development in eastern Wyoming, and by mid-afternoon we were observing some strong convection organize just southwest of Crawford, NE, which is just a 30-minute ride west of Chadron.<\/p>\n
 <\/p>\n

The storm base shown above began to get a good look to it. \u00a0It enjoyed a nice, unimpeded low-level flow of moisture from the southeast, so it was time to get into position. \u00a0We dashed south into the pine trees along Hwy 2\/71 in the Nebraska National Forest and stopped a couple of times as the base continued to spin and move east towards our N-S road.<\/p>\n
 <\/p>\n

 <\/p>\n
The base sported a decent RFD cut, and a rather low wall cloud threatened to issue a funnel cloud. \u00a0Strong westerly RFD winds with the “atomized” raindrops slammed us, cloud motion nearby got rather crazy, and I was pretty excited that a tornado could develop. \u00a0But, like yesterday, this supercell was unable to put a tornado down. \u00a0The supercell continued to the east through an empty area without paved roads, and we stopped again, near Marsland, to check the storm’s structure to our northwest and northeast.<\/p>\n

 <\/p>\n
It was not bad at all! \u00a0The storm was getting rather HP-ish, and chasers lined up on Hwy 385 south of Chadron had a great view. \u00a0In the meantime, other convection was developing nearby. \u00a0 When we reached the “Hemingford” schoolhouse along Highway 2, we had a minute or two to shoot the school and sky before getting too wet.<\/p>\n

 <\/p>\n
On our way east to Alliance, a storm base to our south became quite perky, featuring a brief funnel cloud and a lot of outflow and blowing dust:<\/p>\n

 <\/p>\n
This storm and the original storm to our north looked more HP and less discrete as we reached Alliance. \u00a0So, instead of venturing into the Sand Hills to the east to stay with these, I directed Tom and Woody southward to newer updrafts, towards Angora and Bridgeport. \u00a0Here, we came upon \u00a0another rotating updraft, which sputtered upon arrival and offered a rainbow in apology.<\/p>\n

 <\/p>\n
The sun had another hour or so of shining scheduled, and yet another updraft beckoned a little farther south. \u00a0From Dalton, NE, we headed west on an unpaved road to position ourselves a little south of a nice LP supercell. \u00a0The updraft was smallish, but the anvil and sunset colors were spectacular. \u00a0I have two sets of “LP sunset” images to share — the 21mm versions and the 15mm versions. \u00a0First, the 21mm shots:<\/p>\n
