Starting May 1, as part of the Warn-On-Forecast project, NCEP will be running several high-resolution model ensembles in real time (they are currently being run occasionally on an occasional basis, but will be run daily starting May 1). The HRRRE (pronounced "Hurry") is an ensemble of small-scale, limited-area HRRR runs, initialized every hour and run for 90 minutes at 3-km resolution. The NEWS-e is an even more detailed, smaller ensemble within the HRRRE, initialized every 15 minutes, run at 3-km or 1-km resolution depending on the resources available. The domain areas will change based on the specific severe weather threats on a given day.

The types of products that will be available are everything from the familiar (simulated reflectivity, CAPE, STP) to the more obscure but helpful (updraft helicity) along with all the ensemble-specific products like "paintball" plots, 10th and 90th percentile plots, etc.
