Bad Lake Size

MDL is the National Weather Service Meteorological Development Laboratory and has developed a unified terrain data set that is used in weather forecast issued by NWS. As I understand, the unified terrain data set was upgraded, but the size of the Great Salt Lake was blown up! The lake really isn't that big. This is bad because a large lake effects the weather around Salt Lake in a variety of ways. We've seen a large lake impacts the amount of CAPE near the Great Salt Lake. This could mean the models are more likely to incorrectly forecast thunderstorms. Also, a large lake would effect  forecasted lake breezes and possibly lake effect precipitation. Hopefully this issue will be fixed soon.
