March 2026 Graphical Weather Review: The warmest March on record by a massive margin (and warmer than all but a few Aprils)

March 2026 delivered one of Colorado’s most jarring spring months on record with temperatures skyrocketing to unprecedented levels as the region shattered long‑standing warmth records for weeks on end. Western snowpack rapidly declined during this multi-week heatwave, reaching historic lows in a majority of basins across the West, including every major basin in Colorado. Brief interjections of snow occurred during the month across the Front Range, but most the state ended with well below normal precipitation. Here’s a quick and colorful graphical recap of our weather during March and how it relates to climatology.

NOTE: Please ignore the glitches in the below automated graphic. These are related to March temperatures being so far outside of climatology that the visualization routines cannot handle the data. This will not be fixed this month for timing.

    The fact that your automated system was broken by the heat wave is a perfect metaphor for the month of March
