Around 2330z we switched from the LWX area to BOU where storms have developed and become severe.  There have been reports of a ‘landspout’ tornado near 00z.

Bill and Jessica have mentioned the utility of the updraft field (Merged W Composite) as being an interesting tool for landspout-type environments.

It should be noted that compared to the updraft field looked quite “off” (incorrect) with the storms in the DC domain, but look much better in the Floater (BOU) domain.  Perhaps the 3DVAR we are using is better “tuned” for a supercell environment and the sub-severe storms in the DC area provided a bit more of a challenge.

We will operate for another hour or so and then begin surveys.
