80 degrees on Thursday might be Denver’s last of the year

DENVER -- It will be warm on Wednesday and Thursday in Denver ahead of a weekend cool down with chances of thunderstorms, rain and snow.

Wednesday evening will remain mostly calm. With a partly cloudy sky, temperatures will cool from the day's high in the upper 70s into the 40s through the evening.

Lows on Thursday morning will be in the mid-30s, a chill for the Thursday morning bus stops and commute.

The morning chill quickly warms to 80 degrees by the afternoon, and perhaps the last 80-degree day of the year.

On average, the last 80-degree day of the year in Denver is Oct. 11. The last 83-degree day was Oct. 9, when it was 83 degrees before a strong storm brought the season's first snow.

Denver has recorded record highs in the 80s at the end of October and three times in November.

It is possible there will be a spike in temperatures over the next month or so for an 80-degree day, but historically, it is hard to come by beyond this point.

There's a cool down arriving Thursday night lasting several days.

This weather change might first be noticed during the Broncos game in that the wind might become variable and start to increase. That will mark the arrival of cooler temperatures.

The impact will be highs in the 60s on Friday and Saturday -- normal for the time of year.

There might be isolated thunderstorms Friday into the evening as the colder air establishes itself; the fire danger might be quite dangerous as a result.

A second push of cooler air arrives by Sunday, keeping Sunday and Monday in the 50s.

Those  days will also be Denver's highest chances for rain and snow.

Data show little accumulation at this point, albeit the impact is to be determined for travelers as even minor amounts might lead to ice and an impacted drive.

There will be a warm-up on Tuesday and Wednesday with highs in the 60s to 70s, but another push of colder air arrives after that and will stay with the area through Halloween.
