May 2020 had pockets of interesting weather mixed in with atypically longer dry periods. Here’s a quick and colorful recap of our weather during the month of May and how it relates to climatology.

Top Weather Highlights of May 2020:

  • Isolated severe weather broke out May 19 through May 23 with multiple weak tornadoes touching down in Weld County. There was even a funnel cloud sighting in Broomfield.

  • More than half of Boulder’s precipitation during the month of May fell from a single chilly rain event on May 24th. Outside of this, there were no real storm systems to produce widespread spring rainfall. It was mostly just spotty showers and storms with limited coverage across our area. Not surprisingly, drought has intensified and now reaches further north in Colorado

  • For only the third time in the last eleven years, Boulder ended the month of May with no snow. The stars just didn’t align properly!
