“The RPM model is our in-house real-time forecast model, and the lettersstands for Rapid Precision Mesoscale model. The output allows the display of the latest forecast information on our television graphics. Themodel uses the very successful Weather Research and Forecast model as its forecast engine, a collaborative effort between a host of government and academic agencies. The model is run every three hours out to a period of 51 hours, allowing frequent updates to our forecast products, most important in critical weather situations. Like any weather forecast model, it has its ups and downs, but overall it has been very helpful for our weather forecast efforts.”
It uses the WRF as its engine which isn’t a terrible model. I often look at them in lake effect situations.
