The Real Time Mesoscale Analysis and the UnRestricted Mesoscale Analysis (RTMA and URMA, respectively) provide hourly 2D analyses of near surface variables, cloud fields, and precipitation for CONUS, Hawaii, Alaska, Puerto Rico, and Guam. RTMA products are distributed in support of applications toward situational awareness and the URMA plays a critical role in NOAA's National Blend of Models project, serving as bias correction for the blended output grids. Recent upgrades of the RTMA/URMA system include the addition of new variables, hourly precipitation analyses over CONUS and Puerto Rico and the continued addition of new observations. A new rapidly updating RTMA (RTMA-RU) has also been introduced to the RTMA/URMA suite. RTMA-RU provides an updated analysis every 15 minutes over CONUS in support of the aviation community.

Aggressive development is underway toward improving several aspects of the system to address user concerns. This includes, but is not limited to, changes to the analysis algorithm to improve the fit of the analysis to observations, enhancements to quality control procedures, as well as the addition of new analysis variables.

Recent upgrades, including RTMA-RU, as well as near term plans and progress will be discussed. Longer term plans toward the development of a 3D RTMA/URMA system with sub-hourly updates will also be presented.
