After weeks of warmer-than-normal temperatures, a big cooldown is on the horizon for Denver.
Saturday will be the last warm day with a high of 88 degrees, then it’s down to the 60s and low- to mid-70s through at least Friday. The warmest high next week is 77 degrees. The lowest high expected is 68 degrees.
“Changes are coming in the upcoming week with a hint that fall is right around the corner,” meteorologists at the National Weather Service in Boulder said in their online forecast discussion. “The most notable impacts will be cooler temperatures and a decent shot of rain for late Sunday and early Monday.”
Ending this dry week, Saturday has little storm chances during the day, a 10% chance after 3 p.m., then there is a 20% chance of showers or storms Saturday night.
The low Saturday night is 56 degrees.
Showers and storms are likely Sunday, and especially so on Monday. There is a 60% chance of showers Sunday after noon, and that picks up to a 90% chance overnight Sunday into Monday. Monday has an 80% chance of storms most of the day.
Today, isolated to scattered very light showers will pose little to no threat of burn area flash flooding. Sunday and Monday, expect greater coverage and intensity of showers, and a limited threat of flash flooding to all burn areas, especially Cameron Peak. #CoWx pic.twitter.com/wDuVIbgM27
