Thornton Weather

11/21/2025

Thornton’s weekend weather to offer up a mixed bag of sun and possibly showers. Unsettled weather will take the place of the mild, calm conditions that have dominated recent weeks. However, the change won’t be anything too dramatic and we will continue to wait for any real precipitation. For Friday, we start out with cloudy skies and perhaps a few sprinkles this morning. No appreciable precipitation is expected. The afternoon will then begin to see skies clear. Highs will top out in the upper 40s. Tonight, partly cloudy skies will be above with lows near the freezing mark. Saturday will be the nicest day of the weekend. Conditions will be pleasant with sunny skies and highs near the 60 degree mark. Saturday night, partly cloudy skies will be above and lows will dip to the mid-30s. Sunday seesour next system move in although it won’t be dramatic. Mostly cloudy skies will be above and highs will reach the low to mid-50s. The afternoon and evening will bring some chances for rain showers. Have a great weekend! More: https://www.thorntonweather.com/

Verified: Hurricane Melissa winds set record. 🌀 Last month, the storm tore a path through the Caribbean destroying property and claiming 90 lives. Data recorded from a dropsonde released from hurricane hunter aircraft have confirmed a maximum wind gust in the storm of 252 mph. This sets a record for the strongest verified hurricane wind speed, topping the old record of 248 mph recorded during Typhoon Megi in 2010. 😲

Thursday in Thornton offers near average temps, showers later. The much-anticipated change in our weather pattern is arriving. While much is still up in the air, even this close to it, we are certainly in for cooler temps and a dose of precipitation. Mostly cloudy skies will be above this morning then this afternoon those clouds will fill in and it will become cloudy. High temperatures will top out right near the average high for the date of 51 degrees. Afternoon may see a sprinkle of rain then toward the evening showers become a bit more numerous. This evening and tonight is when we expect precipitation to become more widespread, mainly after about 7:00pm with showers becoming likely through the overnight hours. A decent shot of rain is expected perhaps a quarter of an inch or so. Will there be some snowflakes mixed in early tomorrow as temperatures drop? Maybe. However, if so, at this time, it doesn’t look like it will be enough to accumulate. Overnight lows will bottom out in the mid to upper 30s. More: https://www.thorntonweather.com/

A look at the start of some unsettled weather on the way... Tomorrow will see high temperatures right near normal. Initially there will be partly sunny skies above then the afternoon will see cloud cover increase. Along with that, we will begin to see some chances for rain showers. Overnight Thursday into Friday AM, we could see some decent rainfall amounts on the order of a quarter inch or so. Will there be snow? Maybe. However, at this time it doesn't look like any flakes that fall will amount to anything appreciable.

Denver is now tied for number three on the latest snowfall dates since 1882. Certainly not a list we would like 2025 to be on and it is seeming likely we will climb further up. Tomorrow night / Friday morning there is an outside chance the Mile High City records its first snowfall of the season but precipitation is more likely to just be rain.

Thornton to enjoy another mild, calm day Wednesday. Plenty of blue above and temperatures well above nominal levels will once again be our main weather features for the day. Change is on the horizon, however, for the following couple of days. Today mostly sunny skies start us off then by mid to late afternoon, cloud cover will be increasing. Conditions will be calm and dry. High temperatures will top out in the mid-60s. Tonight, mostly cloudy skies will be above and it remains calm. Overnight lows will drop to the mid-30s. The much-anticipated cool down arrives tomorrow. Temperatures then get close to seasonal normals Thursday and Friday. The big wildcard is the precipitation and what form it will take. At this time, it does appear we will be receiving a good dose of rain, mainly Thursday night. Snow, however, is appearing unlikely. Models have been all over the place with this system so we may not have a good feel for it until tonight or tomorrow. More: https://www.thorntonweather.com/
