Our one-day interlude of cool, damp weather is over. Today sees the sun return and the mercury climb to well above normal levels.
Sunny skies will be with us throughout the day. Conditions will be calm and dry. High temperatures will be topping out in the mid-60s.
Tonight, it will be mostly clear and calm. Overnight lows will dip to the mid-30s.
The biannual ritual of changing our clocks to adjust for Daylight Saving Time occurs this Saturday night providing yet another signal of the changing of seasons. The United States will ‘spring forward’ one hour at 2:00am Sunday morning as we begin Daylight Saving Time.
The ritual of changing our clocks twice a year can be met with some resistance as some people struggle to adjust their body’s internal clock. The start of Daylight Saving Time can be particularly problematic given the one hour less sleep people receive on the night of the change.
However, longer days as we head into the milder months are a very real benefit and for many worth the inconvenience of a lost hour of sleep. The time change definitely has big effects on how much daylight we enjoy during our normal waking hours.
On Saturday, prior to the change, sunset will occur at 5:58pm but on Sunday the sun won’t disappear over the horizon until 6:59pm. This affords folks more time in the evening to get started on those spring-time chores and allows us to get outside and enjoy the warming weather.
Similarly, sunrise on Saturday is at 6:23am but shifts to 7:22am on Sunday.
The March Equinox is also on the horizon. Spring officially begins at 8:46am on Friday, March 20.
This year Daylight Savings Time will come to an end on November 1.
Some of the recent history of Daylight Savings Time (from Wikipedia):
Daylight saving time in the United States was first observed in 1918. Most areas of the United States currently observe daylight saving time, with the exceptions being the states of Arizona and Hawaii along with the territories of Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.
From 1987 to 2006, daylight saving time in the United States began on the first Sunday of April and ended on the last Sunday of October. The time was adjusted at 2:00 AM (0200) local time (as it still is done now).
Since 2007, daylight saving time starts on the second Sunday of March and ends on the first Sunday of November, with all time changes taking place at 2:00 AM (0200) local time.

A very fun celestial event is set for tomorrow morning, but clouds may very well intrude and prevent viewing.
The partial eclipse begins at 2:50am with totality starting at 4:04am and lasting until 5:02am. Our big concern right now is the potential for cloud cover.
At the current time, forecasts show the sky to be mostly clear up until about the time totality begins. Then, we expect a sharp, fast increase in cloud cover with the arrival of a cold front. As such, viewing may be hit or miss.
Set your alarm, get up and take a look, and if clouds are in the way, you are free to go right back to bed. 😀
The Colorado Front Range’s mild, dry winter carried right into February. Indeed, the month offered up the warmest and driest February of the past 20 years here in Thornton.
A narrative for the month reveals there really was not much to talk about. High temperatures were above average on all but two days during the month. There was no recorded precipitation and the only snow we saw was a trace on the 20th.
Thornton’s average temperature for the month came in at 44.3 degrees. This was far above our 20-year running average for the month of 32.4 degrees. It was also our warmest February on record, easily besting February 2017 (40.1 degrees) as the previous record holder.
For Denver, as measured at Denver International Airport, it was a very warm month as well. The Mile High City’s average temperature for the month cam in at 42.1 degrees. This was well above their long term February average of 32.7 degrees. It put the month in the books as the third warmest February on record.
Precipitation registered a big fat zero for Thornton. This is the first time in 20 years that the month recorded nothing and well below the 0.60 inches we have averaged over that period. Our previous driest February of the past 20 years was in 2009 when we recorded 0.08 inches.
The Mile High City saw a scant 0.02 inches in their rain bucket at DIA. This was far below the long term average for Denver for February of 0.41 inches. It was the second driest February on record.
Obviously, with no precipitation recorded, Thornton saw no measurable snowfall either. We saw one day with a trace and that was it. Our 20 year running average for the month of February is 10.7 inches. This was the first February over that period that no snow was recorded.
Similarly, Denver only recorded a trace of snow at DIA. Denver’s February long term average is 7.6 inches. The month tied the Mile High City’s record for the least snowiest with February 2009.

The month of March in Denver is usually one that is welcomed heartily by residents. We begin to shake off the cold of winter with warmer temperatures and calmer conditions. That does not mean we are done with snow and cold by any means.
March usually offers healthy snowfall giving us an opportunity to add to our seasonal totals. While there is good snow potential in March, the month also typically brings much warmer temperatures.
March is historically Denver’s snowiest month and brings about 20% of our annual snowfall. Heavy, wet spring snow storms can oftentimes bring the entire month’s snowfall total in one monstrous snow.
We also start the transition to spring and severe weather season and the month typically brings our first thunderstorms of the year. Temperatures climb throughout the month and by the end our average daytime highs are near 60 degrees.
For a complete look at what lies ahead in March 2026, click here.
February signifies the start of the climb toward warmer temperatures for the year. Cold and snow though do intrude but, coupled with milder conditions, there are lots of photo opportunities as can be seen in our monthly slideshow.
The month is one of our least snowiest of the year but it isn’t unusual to see the landscape blanketed in white. Warming temperatures through the month can bring the onset of spring fever and gives residents the opportunity to enjoy some prolonged time outdoors on the mild days.
Cold or mild, snowy or dry, our scenery is almost always gorgeous – and photo worthy.
Showcasing images captured by ThorntonWeather.com readers as well as some of our own, our monthly slideshow covers the entire gamut of weather-related imagery.
