Throwback Thursday: Images of the June 15, 1988, tornado outbreak in Denver. This was a fun find! I was going through old family photos and came across these images of a famous – and destructive - Denver weather event. At that time, I was staying with my sister at her house on Fox Street near 96th Ave in Thornton. The weather was clearly getting spicy and where she lived provided clear views to the south and southeast. We were amazed to watch multiple twisters strike in and around the city, me grabbing pictures with my old 35mm Canon AE-1 Program. The National Weather Service history for the event describes “several” tornadoes. The most powerful was an F3 that struck in south Denver and was on the ground for 25 minutes. That twister alone damaged 85 buildings and many vehicles. Miraculously, no serious injuries or deaths were reported.

Automated systems are no substitute for in-person enforcement but, if this helps with the lawlessness that has taken over our streets, we are all for it. Don't like it? There is an easy workaround - don't break the law. 🚨🚓👮

Thursday in Thornton to offer warm temperatures, increasing clouds. Another good-looking day ahead for us. We will enjoy temperatures well above average and while clouds will be increasing, that won’t be till later in the day. Sunny skies start us off and will be with us till noon. After that, cloud cover will increase leading to partly sunny skies by late afternoon. Conditions will be calm and dry throughout. Highs will be topping out in the low to mid-80s. Tonight, we remain calm and dry. Mostly cloudy skies will be above as we head for a low in the low to mid-50s. More: https://www.thorntonweather.com/

Cruddy cell phone pic but... I was out working on our SxS trailer and heard the unmistakable call of sandhill cranes. Rushed to get out from under the trailer just in time to catch a quick glimpse of them on their migration. Kind of fun to see. Sure would love to find some of these guys on the ground or flying over when I have my big camera as it has been a few years.

Supermoon! A pretty cool show to the east yesterday evening as the full harvest moon rose in the east. Many of you got some cool captures - thank you for sharing them! If you have any other pics from this month - fall foliage, wildlife, cool scenes, etc - share those too so we can get our October photo slideshow going.

Hearing some raindrops hit our skylights now. We won't be getting much out of this evening's showers though. Thornton topped out at 51.5 degrees today, a big change from recent weeks and is our coldest high temperature since April 25th (45.7 degrees)! Looking ahead, tomorrow will be a day of transition. We will see partly sunny skies and highs in the low 60s. Then we see a nice warmup with highs in the mid-70s to low 80s for the rest of the week.

Winter prep is in full swing at Thornton Weather HQ. Over the past week we drained our little water fountains and yesterday we blew out our sprinkler system. A lot of folks wait (and then panic when we get a freeze) but we have seen little point in doing so and always target the end of September / start of October to do it. Yeah, "the experts" say to wait but in 30+ years of home ownership, our lawn does just fine doing it now. The grass knows it is time to hibernate. We also don't bother to manually water in the winter, even if it is dry. When do you blow out your sprinklers?

Following a nice shot of rain Thornton’s Monday to feature clouds, a little precip. As we posted earlier, Thornton received a healthy 0.50 inches over the past 24 hours. Today, the clouds linger, temps will be cool, and we may see a little more rain. Cloudy skies will be the rule throughout the daytime hours. We might see a little lightening in the coverage mid-day but it will generally be a gray day. The late afternoon brings just a slight chance to see a sprinkle. Highs will top out in the mid-50s. This evening chances for rain increase but any that falls is expected to be light. Skies will initially be cloudy then see a bit of clearing after midnight. Overnight lows will dip to the low to mid-40s. More: https://www.thorntonweather.com/
