Synoptic pattern evolution shows persistent post-frontal upslope flow across the Denver metro for April 27, with enhanced cloud cover limiting insolation. GFS and ECMWF ensemble means are tightly clustered, indicating peak thermal advection aligns with a 56-57°F high. This falls slightly below the 30-year climatological average of 62°F but is strongly supported by current model consensus. We see high confidence in this range. 90% YES — invalid if a strong, unexpected chinook event materializes.
