The previous warmest day seen so late in the year was set in 1892 when Denver reached 90 degrees on Oct. 1.
Saturday’s high also set the daily record for Sept. 30, which was previously set in 1980.
Denver’s warm streak appears to have hit its peak Saturday; next week’s forecast highs ease down into the 80s Sunday and Monday, then to a cool high of 60 degrees Wednesday.
Rain also has reentered Denver’s forecast, with a 30% chance of showers Monday night, and a 40% chance of storms Tuesday.
Low temperatures are also starting to get lower, with Wednesday night’s low dropping to 40 degrees.
The higher mountains south of Interstate 70 could also see up to a couple inches of snowfall next week, and some areas of the plains could get their first morning below freezing Wednesday through Saturday.
Past next Saturday, the NWS’s 8-to-14-day outlook shows most of Colorado has a 50% to 70% chance of above-normal temperatures returning during the second week of October.
Denver’s normals for the second week of October range from 69 to 66 degrees.
Precipitation in Denver that week has a 33% to 40% chance of being below normal levels.
