Welcome

Welcome to the RTMA/URMA VLab community!

The purpose of this community is to facilitate feedback and discussion on the RTMA/URMA system. 

Meeting notes are available under the Google Drive Folder linked above.

To learn more about our next upgrade, see the asset publication below.

Use the System Overview to learn more about the system in general.

Use the forum to ask questions about the system and join the discussion with other users and the development team. 

Note that there are two forums: one for precipitation issues and one for all other variables.

You can post to the precip issues forum by sending an email to qpe.rtma.urma.feedback.vlab@noaa.gov.  For all other issues, you can post by sending an email to rtma.feedback.vlab@noaa.gov.  Please note that you must have a user account to post to the forum.  If you do not have an account, please contact matthew.t.morris@noaa.gov.

We recently added the ability for NWS Regional or WFO personnel to request that stations be removed from the analysis.  To access this, click on the "Station Reject Lists and Requests" tab.

There has been recent interest in knowing exact station locations, especially those of METAR sites.  Our METAR information table is under the "METAR Location Info" tab.

Users may also be interested in the National Blend of Models VLab community.

We appreciate any feedback on how this page or community could be improved.  You can submit such feedback via the above email handle or forum.

Thanks for digging in Dave.  I am definitely curious what is going on in your specific cases here (something for the URMA folks to address). But I do want to mention that the MinT analysis from URMA for this night was very similar to MatchObsAll (bottom two plots). MOA presumably matches all the cold stations that you discuss.  Since the final analysis looks good, URMA has probably been a good source for MaxT/MinT bias-correction.  The NBM forecast minimum temperatures in this case were closer to the observations than NDFD at most stations (top two plots).  I'm not sure why the hourlies you were looking at were so different, but clearly the final answer from URMA was a good one.
