The Weather Prediction Center Development and Training Branch: R2O Activities within the Hydrometeorological Testbed (HMT)

The Weather Prediction Center (WPC) vision of being America’s go to Center for high-impact precipitation and hazardous weather events is supported by the Development and Training Branch (DTB) of WPC. WPC forecast operations range from short term (<6hrs) to long term (up to 7 days). WPC is focused on high-impact precipitation (heavy rainfall, heavy snowfall, and ice) in the short term. At longer time ranges, WPC forecasters prepare forecasts of sensible weather elements (temperature, dewpoint, wind, sky, precipitation, and chance of precipitation) with particular focus on potential weather hazards.

In order to support and advance WPC’s forecast operations; a cornerstone of DTB is the R2O process. DTB engages in collaborative efforts with many scientists throughout the meteorological community focused on heavy rainfall, heavy snowfall, and medium range forecasts. One method for engaging the community is through the Hydrometeorological Testbed (HMT) at WPC. The DTB also leverages the NCEP Visiting Scientist Program and other avenues to stay abreast of the latest science and technology. Particular focus is given to the use of ensembles in the forecast process as well as production of probabilistic products. This presentation will highlight the HMT experimental activities that support operations through R2O to enhance the National Weather Service’s Weather Ready Nation initiative.
