Thornton Weather

Finally a break from the heat as cooler temperatures, moisture arrive for the weekend. I can’t remember the last time I created a forecast graphic that didn’t have a “9” as the first digit in the high temperature! This is wonderful! LOL! A cold front arrives later this morning and with it, monsoonal flow from the southwest will increase moisture. Between the two, cooler temps and precipitation will be on tap in the coming days. For today, mostly sunny skies starts us off and highs will be in the mid-80s. Mid-afternoon we begin to see chances for thunderstorms with showers that will continue into evening. Some of the afternoon thunderstorms could deliver a fast, heavy shot of rain if we are lucky. Tonight, a few sprinkles will be possible. Saturday will see partly sunny to mostly cloudy skies above. Highs will be in the mid to upper 70s. Sprinkles of rain will be possible in the morning. The afternoon may see some thunderstorms. No significant precipitation is expected however. Sunday will be dry in the morning with increasing clouds. Highs again will be in the mid to upper 70s. The afternoon and evening bring chances for showers and thunderstorms. It should be noted that for the weekend, while we may see a thunderstorm make a nice, fast bit of rain, overall precipitation won’t be anything crazy. Monday does bring a better chance for a good soaking. No matter what, I think just about everyone is glad to have some cooler temps. Have a great weekend! More: https://www.thorntonweather.com/

I won’t even ask if you are ready for this as I could easily guess the answer. 😉 Thornton topped out at 96 degrees today, thankfully a few degrees cooler than expected. Tomorrow, a cold front will move in and bring some real, lasting relief from the heat and dry that has dominated the month of August thus far. Cooler temperatures and varying chances for thunderstorms / rain will be the rule well into next week.

Good! Now we can get the water that the city worked so hard to secure for us decades ago.

As a side note, that was back when all members of council could work together for the betterment of the city. Sadly that is not the case anymore it seems. Now days everyone has their own agenda and it is as divisive as national legislative bodies. That is sad and ultimately it is Thornton residents that pay the price.

The nonprofit environmental advocate Save the Poudre is ending its legal fight against the controversial Thornton water pipeline, saying it will not appeal a state district court’s endorsement.

Tuesday in Thornton offers up toasty temperatures, dry conditions. It is becoming a struggle to come up with headlines that are at least a bit different than what we have used before. How many ways can you say “hot and dry” as we have done repeatedly this summer? Well, here it is, again, and you will see it more this week. Sigh. Anyway, look for sunny skies to dominate the day with a few clouds coming along this afternoon. Overall conditions will be calm and dry. Look for highs to reach the mid-90s again. Tonight, temperatures will drop to the low to mid-60s under mostly clear skies. Conditions will remain calm. More: https://www.thorntonweather.com/

Yeah, another toasty one with Thornton topping out at 94 degrees. Thankfully we have since cooled down a bit due to outflow from thunderstorms east of us. Tomorrow look for similar highs. Webcams: https://www.thorntonweather.com/webcam.php
