Climo for DEN late April is ~62°F. 40-41°F represents a deep negative anomaly, requiring persistent Arctic advection. Hitting this tight range as the high is extremely low probability without significant model consensus for a major late-season cold snap. 90% NO — invalid if GFS/ECMWF converge on sub-42°F.
