DENVER (KDVR) — Thursday will be a touch cooler at 83 degrees in Denver with sunshine and good air quality.  The atmosphere is very stable with no thunderstorm risk.

The mountains stay sunny and dry with good air quality.  No thunderstorms are expected there.  Highs will be in the 60s and 70s.

Colorado stays smoke-free through early Sunday.

The 90s return Friday, Saturday and Sunday. Saturday and Sunday will be near-record levels and dry.

Labor Day looks mostly dry but a strong cold front barrels in late. High temps will hit 85.  Depending on the timing of the front, the high could get close to 90. 

Right now the total number of 90-degrees days for 2020 stands at 69. The all-time record is 73 days, set in 2012. We will get very close to this record and tying it might come down to Labor Day.

A Pinpoint Weather Alert Day has been issued for Tuesday due to the huge drop in temperatures.

This cold front could drop temps by 40 degrees. Highs will be in the 50s on Tuesday with rain showers in Denver and across the Front Range. Snow is possible in the mountains and foothills. 

Overnight lows drop into the 30s. The earliest first freeze on record occurred on September 8, 1962. Ironically, that corresponds to Tuesday next week.

The Pinpoint Weather team will continue to track the system — and the snow chances it could bring — as it nears Colorado.

Highs stay cool on Wednesday too, with Denver topping out in the 60s.
