Temperatures warmed into the 90s Sunday setting a daily record, and tying a record for 3rd latest occurrence of a 90° day in a calendar year. Denver may not be done with record heat this week, although a "cold" front will arrive today.

Record-setting on a number of tallies: Sunday's high hit 92°, which ties the daily record high for September 29th, first set in 1892. We've had the 4th most 90° days this year, with the tally now at 64 days; the most on record is 2020 with 75. This also marks the hottest temperature ever recorded this late in the year. Here are the record-latest 90° days.

It appears that the city is not quite done with 90s as it will make a run at another one this Wednesday. If we hit 90°, that'll be the latest occurrence on record and will set a daily record by two degrees. Our WeatherBoard shows how far from records select cities will be this week.

Check out Grand Junction, possibly setting records every single day. Denver has a chance to set Wednesday and Saturday's records.

Cold Front Arrives Today: Although today cools off leaving tomorrow one of the coolest days this week, it clearly doesn't last long. Plus, with very little moisture in the outlook we may catch some wind to further increase the fire danger across the region.

The forecast for the week:

Sure, we've been teased with model data that suggests a cool off is coming with rain and snow but that has remained just a tease; no viable signs of a major weather change anytime soon. Soon, as in within the next seven to ten days.
