DENVER - Sunday is going to be your last gorgeous and well above average warm day -- at least for a week. Temperatures start dropping Sunday.
Saturday, Denver officially tied the record of 80 degrees after breaking the record high on Friday.
All that goes away Sunday night. An upper-level low pressure system will move into the area, high pressure will move on out, and we will see a big change in the forecast by the start of the work week. The biggest difference you will notice with this storm is the cooler air that will filter in behind it. Highs will go from the 70s on Sunday to the 50s by Monday and Tuesday. There is only a slight (20 - 30 %) chance of rain with this system on Monday morning as it moves on through.
Low temperatures however will drop to near freezing in some Front Range cities Monday and Tuesday morning.
Another system, although weaker, will sweep across Colorado Wednesday afternoon and early Thursday, bringing a slight chance for showers on the plains and light snow in the mountains.
Looking ahead to Halloween, it appears that the weather will be cool, but dry for the trick or treaters!
