Record rainfall

One heck of a good dousing! Thornton and Denver received a big shot of rain for the day and in the process, the Mile High City set a record.

As measured at Denver International Airport, the city received 2.92 inches of rain. This easily bests the previous record rainfall for May 11 of 1.55 inches set in 2011.

Here in Thornton we received less but still a very generous amount. We measured 2.38 inches in our bucket, our wettest day of the year so far.

As measured at Denver International Airport, the Mile High City’s low temperature today was only 55 degrees. This sets a new record warm minimum for the date, breaking the old record of 53 degrees set inn 1932.

Thornton stayed even warmer with a low of 59 degrees soon after sunrise.

Here in Thornton, we topped Denver’s mark with a high of 86.9 degrees.

More heat is on tap as we are likely to set a record high tomorrow as well.

Normally, March sees a considerable warmup as we start the transition to spring. If you felt like that was not the case this March, you would be correct.

Thornton’s average temperature for March 2023 came in at 37.1 degrees. This was 5.1 degrees below our running 16-year average. In fact, the month goes in the books as the second coldest March over that same period with only March 2019 being colder (35.1 degrees).

Out at Denver International Airport where the Mile High City’s official measurements are taken, it was actually colder with an overage of 35.9 degrees. That was well below the long term March average for Denver of 41.6 degrees.

Thornton’s temperatures ranged from a high of 73.9 degrees on the 15th down to a low of 15.9 degrees on the 18th. Denver saw a max of 71 degrees on the 15th and its lowest reading of 13 degrees on the 28th.

In terms of precipitation, Thornton ended up pretty much near average. 1.14 inches was recorded between rain and snow melt. That was just shy of the 1.24 inches 16-year average for March.

Denver came in drier with 0.49 inches in the bucket, well short of the long term Denver average for March of 0.86 inches.

Snow was not a big factor during the month, despite the cold. Thornton saw 7.5 inches of the white stuff, well below the running March average of 10.7 inches.

Out at the airport, Denver recorded 5.1 inches, less than half ther March average of 11.5 inches.

Thornton’s April 2023 weather preview: Winter, spring and summer all in one month

Leave a comment

Thornton's April weather previewApril marks a transition between winter and summer for most of the country but for Denver it is especially true as we can see a stunning variety of weather.

The proverbial April showers are certainly a possibility for Denver. Snow? Tornadoes? Thunderstorms? You bet – all can happen!

For good measure throw in a chance for hail and even dust storms and April gives every type of weather condition you could like – or hate.

Time to ‘spring forward’ as Daylight Saving Time begins March 12

Leave a comment
Daylight Saving Time
The United States returns to Daylight Saving Time at 2:00am Sunday as Standard Time comes to an end.

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 6:02pm but on Sunday the sun won’t disappear over the horizon until 7:03pm.  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 6:17am but shifts to 7:16am on Sunday.

The March Equinox is also on the horizon.  Spring officially begins at 3:24pm on Monday, March 20.

This year Daylight Savings Time will come to an end on November 6.

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.
