A pleasant, early fall day like we love on tap today. Temperatures will be right near average for the date with a good bit of sun and just a slight chance for a shower.

Mostly sunny skies start us off and will be with us most of the day. Mid to late afternoon through the evening offer up just a slight chance for a shower. Any activity that does develop will be much lighter and far more widespread than yesterday. Look for high temperatures right around the 70 degree mark.

Tonight, any showers will end by midnight. Skies will then see some clearing. Overnight lows will dip to the mid-40s.

Monday looks to offer up similar weather conditions to what we have seen the last few days. Temps will top out right near normal and we expect to see some shower activity in the afternoon and evening.

Partly sunny skies will start us off and be with us for most of the day. Conditions this morning will be calm and dry. Early afternoon may see an isolated shower or two. Chances for activity increase in the mid-afternoon with the best opportunity coming in the evening. Highs will top out right near the average for the date of 71 degrees.

Tonight, the evening will give our best chance for showers. By midnight most showers will have ended. Skies will be partly to mostly cloudy with overnight lows in the mid-40s.

Keep an eye out for those showers here.

Low pressure intrudes this weekend, breaking down the ridge that has kept us so warm. As it does, we see temps get closer to normal and will have some pretty good chances for showers.

For today, mostly sunny skies will be with us this morning then cloud cover will increase. The afternoon introduces a chance for thunderstorms and showers, mainly from about 3:00pm to 9:00pm. Highs will top out in the mid to upper 70s. Tonight, showers will come to an end and we will see a bit of clearing. Overnight lows will dip to around 50 degrees.

Saturday may start with some fog then we will have partly clear skies for the balance of the day. The afternoon and evening offer up another chance for showers and thunderstorms with timing similar to today. Highs will top out near the 70-degree mark. Saturday night, any storm activity should end by midnight. Lows will be in the upper 40s.

Sunday continues with similar conditions but with lesser chances for showers. Partly sunny skies will be above and highs will top out in the low 70s. Some light showers will be possible in the afternoon and into the evening. Have a great weekend!

We have one more day with temps well into the 80s in store today. There will be just a bit of a chance for a  shower / thunderstorm.

Mostly sunny skies start us off with more clouds slowly building throughout the day. By mid-afternoon, it will be partly sunny. The afternoon brings a slim chance for a thunderstorm or shower. Any storms should be quite isolated and not very dramatic. High temperatures will again top out in the mid-80s.

Tonight, lows dip to the low 50s under partly cloudy skies.

Looking ahead, cooler, and possibly wetter weather, looks to be in store for the weekend and into next week. More in the extended forecast.

Oh, TWC, the invented drama and stupidity you put on display is why I refuse to watch you. Today, their top guy, Jim Cantore, got hit with a tree branch while stupidly standing out in the open reporting on Hurricane Ian.

I certainly never wish harm on anyone but if you do stupid stuff like this, you get what you deserve. He is lucky it only hit his leg and not his head.

Of course I suppose at least this portrayed reality, unlike previous coverage which could only be called “fake news.”

The month of September is typically one of the more pleasant months in Colorado.  Temperatures are usually comfortable and there is not normally a lot of weather drama.  That however does not mean there aren’t plenty of photo opportunities.

Wildlife is still quite active along the Front Range and flowers will hold on to their petals for at least the first part of the month.  Then of course there is the weather which you never know what to expect.  Thunderstorms, heavy rain, and even snow are a possibility.

Another pleasant, early fall day ahead for Thornton. We again will enjoy lots of sun and mild temperatures but there may be some isolated thunderstorms late.

Sunny skies start us off and will be with us through the morning. The afternoon will bring a few clouds. The increased moisture does introduce a slight chance for a thunderstorm, mainly from about 3:00pm and then for a couple of hours. At this time, we aren’t expecting much out of the few storms that may form. High temperatures will top out around the 80 degree mark.

Tonight, skies will be partly cloudy then see gradual clearing late. Overnight lows will be around 50 degrees.

Colorado’s famously inconsistent weather can be seen in our look back at this week in Denver weather history. Not only do we see damaging thunderstorms and winds but even major snowstorms that deposited more than a foot of the white stuff on the city.

From the National Weather Service:

25

In 1873…a fire was sighted in the woods near Platte Canyon… Probably caused by high winds blowing sparks among the timber.

In 1896…an apparent cold front produced northeast sustained winds to 40 mph with gusts to 48 mph.

In 1910…a thunderstorm produced sustained north winds to 51 mph. This was the highest recorded wind speed in the city in September at the time.

In 1936…a vigorous cold front produced a deadly dust storm in the city. North winds sustained to 36 mph with gusts to 38 mph produced much blowing dense dust…greatly restricting the visibility. The temperature plunged from a high of 84 degrees to a low of 38 degrees by midnight. The weather observer described the event with the following. “at 6:00 pm the temperature was 82 degrees and the wind velocity was only 4 mph; but with the wind shifting to the north and the barometer rising quite rapidly…the temperature fell sharply. By 6:30 pm…the wind velocity increased rapidly and by 7:00 pm had reached a maximum sustained velocity of 36 mph…bringing with it clouds of dust which had been picked up by gale force winds in southern Wyoming and northern Colorado…covering the city. The visibility was generally reduced to about 1/4 mile; however…the whirling of the dust down the streets and alleys…the visibility was at times somewhat less. Airplanes were grounded…traffic was halted at times…and homes filled with dust. The strong winds damaged electric power and telephone lines…leaving homes in darkness for a few hours in the city and for 18 hours in suburban towns and putting 2500 telephones out of service because of broken lines. An electric lineman was killed while repairing damage by the high winds. The dust storm was followed by rain that began falling at 10:55 pm…which turned to snow during the early morning hours of the 26th. A major snow storm followed on the 27th through the 29th.”

In 1999…high winds developed in the foothills of Boulder County. Winds gusted to 90 mph at Wondervu.

25-26

In 1908…apparent post-frontal rain changed to snow overnight and totaled 6.5 inches in downtown Denver. This was the first snow of the season. Precipitation totaled 0.76 inch. North winds were sustained to 39 mph on the 25th.

25-27

In 1996…an early season snowstorm brought heavy snow to the Front Range eastern foothills. Snowfall totals included: 8 to 12 inches around conifer…7 inches on Floyd Hill…and 6 inches at both Bailey and Chief Hosa. Snowfall totaled only 4.7 inches at the site of the former Stapleton International Airport. This was the first measurable snow of the season. After the passage of a strong cold front…north winds gusted to 38 mph at Denver International Airport on the 25th.

26

In 1907…a late afternoon thunderstorm produced hail…0.23 inch of precipitation…and north winds sustained to 24 mph.

In 1927…snowfall of 1.7 inches…mixed at times with sleet… Was the first measurable snowfall of the season.

In 2012…a man was seriously injured when he was struck by lightning outside the Hebrew Educational Alliance as he and his family were getting in their car. The victim stopped breathing but was saved when his wife performed cardiopulmonary resuscitation on him immediately.

26-28

In 1936…the heaviest snowfall ever recorded in September and the heaviest snowfall ever recorded so early in the season dumped a total of 16.5 inches of snow on downtown Denver and 21.3 inches at Denver Municipal Airport. The 15.0 inches of snow measured from 6:00 pm on the 27th to 6:00 pm on the 28th is the greatest 24 hour snowfall ever recorded in September. This was the first snow of the season. The snow was intermittent through the 26th…but continuous from early afternoon on the 27th to around midnight on the 28th…except for a period of rain during the afternoon of the 28th which contributed to a loss of depth on the ground. The greatest snow depth on the ground downtown was 13 inches with 8 inches at Denver Municipal Airport. There were no high winds with the storm and traffic was interrupted for only a short period. The storm produced property damage estimated at 7 million dollars. With trees and shrubs in full foliage…the leaves caught and held the heavy water-laden snow…until the branches snapped from the weight. More than 3000 workmen were called to remove the debris and snow from the city. The city firemen who were off duty…as well as all the reserves… were asked to report to their stations. All schools in the city remained open…but attendance was only 50 percent of normal. Grade school students were sent home at noon on the 28th. The early storm caught stockmen with many cattle still in higher ranges. Warm weather followed the snow…which had all melted by the end of the month…except for a few inches in sheltered places. » Click here to read the rest of September 25 to October 1: This week in Denver weather history
