I don't have the ability to post in the target area forum, so I thought I'd post this here; I encourage those who can post in that forum to note this information to those currently posting there about dew points and cape values in the RUC.
A new version of the RUC will be implemented at the end of June. I'll spare the many details of the changes right now, but one item of significant relevance is the much improved handling of soil moisture. The operational RUC tends to dry out sfc moisture way too quickly, and the new version has shown significant ability to generate a much more realistic evolution of it.
Graphics are available at http://www.emc.ncep.noaa.gov/mmb/ruc2/para
The problem today is that the machine on which I generate the graphics is unavailable today; I have, however, been able to produce a limited set of graphics for some of the fields.
I am posting this, as I have seen many comments in the target area forum about the model's handling of dew points and resultant cape over the SD/NE region late today. If you examine the 18z cycle on my page, you'll see that the new version of the model keeps much higher dew points and cape across this region this evening. The soil moisture availability field shows the differences that at least partly explain the discrepancy.
I apologize that the site is incomplete today, but I thought it worth pointing out with so many folks closely examining the parameters in NE/SD today. The site should be completely reliable tomorrow.
