On 17 May 2018, MRMS Version 11.5 became operational in the National Weather Service (NWS). This build contains a number of updates that impact the generation and delivery of MRMS QPE products. These changes include the ability to handle new volume coverage patterns from the NWS fleet of WSR-88D radars, new radar quality index logic, more hourly gauges, and reduced product latency.

The next version of MRMS (v12.0) is tentatively scheduled to become operational in January 2019. More details will be provided soon on MRMS v12.0, which contains the biggest advancements in the generation of QPE in MRMS since the initial operational release back in 2014. Stay tuned…
