Multi-Sensor Precipitation

Wintry Conditions in the Plains; Unsettled in the West

A storm system producing wintry conditions will slowly move east and into the Middle Mississippi Valley. Rain will spread across the Deep and Mid-South with this system. In the Pacific Northwest, weather systems will continue to parade through the region. Snow levels will vary with the passage of each storm, and rain is expected in the lower elevations. Read More >

Radar-Derived Precipitation Estimates

Radar-derived Precipitation Estimates are a combination of Radar data and rain gauge observations. These estimates may be referred to as MPE values because they are derived by using the Multi-Sensor Precipitation Estimator (MPE) Program. This data may also be referred to as Stage III data, because the MPE process is the third stage of quality control on the radar-derived precipitation amounts. Hourly Radar rainfall estimates are compared to hourly gauge values to produce hourly MPE values.
