Case Description

Reason for interest: high-resolution window performed worse than NAM

Isentropic lift over a cold dome of air initiated thunderstorms over the Texas panhandle, which later formed into an MCS and moved northeast across the plains into Missouri, bringing a great deal of rain in a swath from the Texas panhandle to western Illinois. Minimal severe reports were associated with this system on 7 October.

This day is particularly interesting because the NAM QPF performed quite well (although it did over-predict precipitation totals over the Texas panhandle) while the high-resolution window missed most of the eastern half of the precipitation event.
