Hey, y'all...

Rehashing a previous topic here.

We've been having some significant issues with the Clarksdale, MS (CKM), observation the past month or so. The dewpoint is essentially matching the temperature throughout much of the observation period, especially during the day. This results in afternoon dewpoints in the lower 90s. While this data is being kicked out of URMA by 1900 UTC, it is making it into the system through 1800 UTC and causing some bias issues and significant heat indices.

I'm relatively new in the SOO role and haven't had to deal with this before, but is there still a blacklist for ingesting observations into URMA? I've attached the 1800 UTC QC documentation from yesterday and a screenshot of today's dewpoints at 1500 UTC.
