Thornton’s weekend weather to see warming temperatures, dry conditions

Friday, March 18th, 2022 5:07am MDT

With another snow in the books, Mother Nature is being kind enough to return us to drier, warmer conditions for the weekend. Each day will get gradually warmer and overall conditions will be calm.

For Friday, we will enjoy mostly sunny skies above with calm conditions. Highs will top out today in the low to mid-50s. Tonight, lows will be in the mid-20s with mostly clear skies.

Saturday offers up the most sun of the three-day period. Sunny skies will be above and highs will reach the mid to upper 50s. The afternoon will see some breezy winds. Saturday night, cloud cover will increase with lows around freezing.

Sunday will be the warmest day of the weekend but also with some additional cloud cover. Look for highs in the low to mid-60s under partly sunny skies.

Be sure to get out and enjoy the relative warmth. Our next storm system arrives Sunday night and will offer up chances for snow and colder temperatures through Tuesday.

Wet snow, cold temperatures for Thornton’s Thursday

Thursday, March 17th, 2022 5:09am MDT

Well, our storm didn’t quite pan out as expected for us. While areas west and south are being hammered pretty good, the transition from rain to snow occurred later for us and has limited the storm’s impact. We will continue to see snow fall but it isn’t going to be as big of an event as expected.

Cloudy skies start us off and by around noon it will slowly begin to ease. High temperatures today will top out around 40 degrees.

Another inch or two will be possible between now and noon, then things will slowly taper off, ending entirely by late afternoon. The Winter Storm Warning does remain in effect until noon although it likely could stand to be dropped for our area due to the storm’s limited impact.

Tonight, skies will continue to clear and it will be dry. Overnight lows will drop to around 20 degrees.

March 13 to March 19: This Week in Denver Weather History

Wednesday, March 16th, 2022 4:25pm MDT

This Week in Denver Weather History

Snow is one thing we have not seen a lot of in recent weeks but we still have time to gain ground. March is our snowiest month and our look back at this week in Denver weather history provides evidence of this. It was this week 13 years ago that the Denver was struck by a massive snowstorm – the costliest in Denver history. Also, six years ago, we saw significant snowfall this same week. Below is a complete look at those and other events.

From the National Weather Service:

9-19

In 1906…an extended cold and blustery period occurred with light snow totaling 14.4 inches over 11 consecutive days. The greatest amount of snow on a single day was 4.0 inches on the 15th. Only a trace of snow fell on the 12th and 17th. High temperatures were below freezing for the entire period. The coldest were 14 degrees on the 16th and 18 degrees on the 17th. Both readings were record low maximums for the dates. Low temperatures were mostly in the single digits. The coldest were 2 degrees below zero on the 16th and 5 degrees below zero on the 19th. Northeast winds were sustained to 22 mph on the 9th. North winds were sustained to 36 mph on the 10th…32 mph on the 13th…and 22 mph on the 15th.

12-13

In 2005…a winter storm brought heavy snow to the eastern foothills and western metro Denver overnight. Storm total snowfall included: 15 inches in Jamestown…13 inches near Blackhawk…11 inches in the foothills southwest of Boulder and near Nederland…10.5 inches at Gross Reservoir…9.5 inches at Eldorado Springs…9 inches at Roxborough Park… 8.5 inches near Longmont…8 inches in Boulder…7.5 inches at Centennial…7 inches in Louisville…3.3 inches at Denver Stapleton. At Denver International Airport…west winds gusted to 46 mph on the 12th before the passage of the cold front and north winds gusted 31 mph on the 13th.

12-16

In 1880…a protracted cold spell resulted in 8 temperature records being set. Record low temperatures for the date were set when the temperature dipped to 10 degrees below zero on the 13th and 14th…8 degrees below zero on the 12th and 15th…and 4 degrees below zero on the 16th. Daily record low maximum temperatures were set with 11 degrees on the 12th…12 degrees on the 13th…and 19 degrees on the 15th.

In 1990…4 to 9 inches of snow fell across metro Denver with 8 to 16 inches in the foothills. Morrison reported 9 inches; Evergreen…11 inches; and Aspen Springs…14 inches from the storm. Blowing snow and reduced visibilities caused 2-hour delays at Stapleton International Airport where only 5.1 inches of snow fell and north winds gusted to 21 mph.

13-14

In 1996…a storm system moving across northern Colorado dumped heavy snow in the mountains and foothills and across metro Denver where snowfall ranged from 5 to 10 inches. A foot of new snow was measured at Nederland with 11 inches at Conifer. Snowfall totaled 8.0 inches at the site of the former Stapleton International Airport. Northeast winds gusted to 30 mph at Denver International Airport on the 13th.

In 1902…west winds were sustained to 40 mph with gusts to 48 mph.

In 1913…strong winds all day behind a cold front made for a blustery cold day as the high temperature climbed to only 25 degrees after a low of 19 degrees. Northeast winds were sustained to 51 mph with gusts as high as 60 mph. Only a trace of snow fell.

In 1920…west winds sustained to 43 mph with gusts to 50 mph warmed the temperature to a high of 67 degrees.

High temperatures ranged from 65 degrees on the 14th to 72 degrees on the 16th.

In 1983…a heavy wet snowstorm buried metro Denver with the foothills receiving the most.

Boulder received 12 to 18 inches. Flight operations at Stapleton International Airport were limited to one runway for a time. Some roads and schools were closed…and power outages occurred when wet snow downed lines. Snowfall on the 15th and 16th totaled 7.2 inches at Stapleton International Airport where north winds gusted to 30 mph. Maximum snow depth on the ground was only 6 inches due to melting.

Wednesday brings cooler temperatures, chance for rain and snow late

Wednesday, March 16th, 2022 4:59am MDT

Our next weather maker is on its way and will make itself felt today. We start out calm and dry but by tonight, rain and snow arrive.

Partly to mostly cloudy skies will be above to start things off then cloud cover will increase as the front approaches. High temperatures today will top out in the low 50s in the mid-afternoon then begin a decline.

Early to mid-afternoon we may see a few sprinkles of rain. Late afternoon and evening then see precipitation increase with rain initially then a transition to snow around 7:00pm or so. Snow will then continue through the overnight hours with us potentially waking up to 2 to 4 inches tomorrow morning.

As is oftentimes the case with these spring storms, the key factor is going to be the timing of the transition from rain to snow. An earlier transition means more snow, later would mean less snow but more rain.

Highlighting that uncertainty, the National Weather Service has issued a Winter Weather Advisory to go into effect from 6:00pm this evening to noon tomorrow. They mention the possibility of 2 to 8 inches total snowfall although areas west and south are most likely to see the higher amounts.

Overnight lows tonight will be a bit below freezing.

Time to spring forward as Daylight Saving Time begins Sunday, March 13

Thursday, March 10th, 2022 10:29am MDT
The United States returns to Daylight Saving Time at 2:00am Sunday, March 14, 2021.

The United States returns to Daylight Saving Time at 2:00am Sunday, March 14, 2021.

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 6:03pm but on Sunday the sun won’t disappear over the horizon until 7:04pm.  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.

The March Equinox is also on the horizon.  Spring officially begins at 9:33am on Sunday, 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.

Daylight Savings Time Schedule

Year DST Begins 2 a.m.
(Second Sunday in March)
DST Ends 2 a.m.
(First Sunday in November)
2022 13 March 2022 6 November 2022
2023 12 March 2023 5 November 2023
2024 10 March 2024 3 November 2024
2025 9 March 2025 2 November 2025

Denver smashes record low temperature for March 10

Thursday, March 10th, 2022 5:46am MDT

Record Cold Temperatures

Old Man Winter isn’t done with the Mile High City just yet as evidenced by the bone-chilling cold this morning.

As measured at Denver International Airport, Denver’s low temperature plummeted to -7 degrees this morning. That easily bests the previous record low for March 10th of -3 degrees set in 1932.

Additionally, it puts March 10, 2022 into the books as being one of the top 10 coldest March temperatures on record and is the Mile High City’s coldest March reading since 1960.

Here in Thornton, we managed to escape getting quite that cold. We saw a low of 0 degrees at 4:12am.

Thornton’s latest storm winds down Thursday, temps remain very cold

Thursday, March 10th, 2022 5:01am MDT

With an additional half inch of snow overnight, our total for this latest storm comes in at 1.1 inches. Today, we may see a few more flakes fall but they won’t amount to much and temperatures are going to remain quite cold.

Cloudy to mostly cloudy skies will be above throughout the daytime hours. High temperatures today will top out only around 20 degrees. While we may see a flurry or two today, no accumulation is expected.

Tonight, skies will begin to clear and overnight temperatures will again drop to the single digits.

Looking ahead, tomorrow we will see the blue sky return and while it will remain chilly, it will be warmer than recent days. The weekend ahead looks to be quite pleasant with a return to above average temperatures. More in the extended forecast here.
