Map of projected temperature anomalies next Thursday across the western U.S. from the ECMWF ensemble. The entire map is bright red and pink, indicative of extreme to record-breaking March warmth. Some location will be 25-30F degrees above average, with a few locations warming over 35F (!) above average.

All signs continue to point to an exceptional, long-duration, and record-breaking to (in some cases) record-shattering March heatwave initially centered across U.S. Southwest but expanding to much broader region next week. This is effectively a full-on summer heatwave in March.
