Supercells and Possible Brief Tornado?

Greetings from everyone's favorite town of Ogallala once again, this time from the Comfort Inn, a substantial upgrade on the Super 8 across the street. Very little time to write tonight as it's already 1:51am local time, and we need to be leaving by 9:00-10:00 am tomorrow morning. Anyhow, observed several supercells in E WY and W NE, one of which tried very hard to, and may have produced a brief tornado/landspout just north of the city of Lusk, Wyoming. Certainly the best day of the trip so far, with 3 or 4 supercells observed, 1 possible tornado (we'll post photos), and some excellent structure. If I have time tomorrow, I'll try and elaborate on the Lusk storm a bit more. Adios for now. Initial target of just east of Castle Rock, CO tomorrow.
