Dual Pol QPE performed better than or similar to PPS estimates despite the continuing differential reflectivity calibration challenges. Although Dual Pol QPE challenges in the melting layer were present in some cases, particularly in the Northeast region, they were not as common as was observed during the 2013-2014 cool season. Q3RAD estimates performed better than Dual Pol and PPS over the Northeast, Southern Plains and the Southeast/Mid-Atlantic regions, with overall performance statistics second only to the forecaster quality controlled Stage IV estimates. Over the Great Lakes/Midwest and the Northern/Central Plains, a distinct Q3RAD overestimate bias was noted although Q3RAD remained competitive with the radar-only estimates. The overestimate bias was primarily due to the MRMS system too often classifying radar echoes as tropical. Hence, the 850–500 hPa lapse rate requirement, which affects tropical precipitation classification, was adjusted to favor weak CAPE environments. A test of the new precipitation classification requirement using 15 precipitation events revealed a significant reduction in the overestimate bias; the adjusted code should be operationally implemented before the 2016 warm season. Finally, Q3gc estimates generally improved upon the Q3RAD estimates and in some regions/cases were very close to the Stage IV performance statistics.
