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.

For NCEP Stage II/IV users: upcoming changes (Mar 2020)

Hello.  A number of changes are planned for the NCEP Stage II/IV analysis, to be implemented with the RTMA/URMA v2.8 in March 2020.  High light of changes:
  • Stage II will be discontinued with the RTMA/URMA v2.8 implementation (scheduled for Mar 2020)
  • Stage IV will be in GRIB2 format, instead of GRIB1
  • Subject to NCEP/NCO approval, Stage IV mosaicking will be done at hh:55 instead of hh:33 (per request by OWP, RFCs for RIDGE II, so that more RFC QPEs can be included for the current hour)
  • There will be an additional re-run for 24h ConUS mosaic done at 30h after valid time (at the 18:55Z cycle), to supplement the current 1/2/3/5/7-day rerun schedule, done at 12:55Z, to give RFCs a better chance to have their re-sent or updated QPEs included in AHPS’s water.weather.gov/precip w/o waiting for the 2-day rerun the next day
Parallel data available at: https://para.nomads.ncep.noaa.gov/pub/data/nccf/com/pcpanl/para/

A 2-page summary of changes, with detailed list of file name changes and link to add'l info about the RTMA/URMA v2.8 upgrade, can be found at
