Denver Weather: Red Flag Warning and hot temperatures Monday, with possible snow later this week
Another hot and sunny day in the Denver Metro area, but high temperatures aren’t expected to last long this week.
Monday is looking partly sunny, but temperatures will remain warm, with highs reaching 81 degrees and a Red Flag Warning according to the National Weather Service in Boulder.
That’s only 1 degree cooler than the average high for March 30 in Denver, according to weather service archive data. The record high for this date was 82 degrees, set only 16 years ago in 2010.
“Continued warm and dry today with increasing west winds leading to critical fire weather conditions,” said the National Weather Service in Boulder on X. “Rapid fire spread possible with any new starts. Avoid any outdoor activity that can create a spark!”
