GFS and ECMWF ensemble means for May 10 consistently indicate a robust thermal ridge over Colorado, driving diurnal heating well into the mid-to-upper 60s. Boundary layer mixing under ample insolation suggests a high probability of exceeding 63°F. Surface analysis shows warm advection prevailing; no significant shortwave trough or cold airmass intrusion is forecasted to impede this warming trend. Expect daily max temps to track higher. 85% NO — invalid if a significant Arctic front pushes through after May 9.
