Weak system to chill Thornton out Wednesday, possibly bring a touch of snow

Wednesday, March 1st, 2023 4:59am MDT

A return to wintry conditions today as a system moves through. It will, however, be more of a show for the mountains with little effect for us.

Mostly cloudy skies will be above throughout the day today. Temperatures will be chilly with highs in the low to mid-40s. Breezy winds this afternoon will make it feel colder.

After noon we begin to see some chances for snow that will last through tonight. At this time, we aren’t expecting much at all in terms of the white stuff, maybe a half inch or so between noon today and dawn tomorrow.

Tonight, flurries / light snow will be seen. Lows will drop to around 20 degrees.

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.

Sunday, February 26th, 2023 5:00am MDT

This Week in Denver Weather History

In the past week Denver has seen its fair share of wind and snow and looking back at this week in Denver weather history, we see both are common conditions.

From the National Weather Service:

22-29

In 1960…heavy snowfall of 6.1 inches at Stapleton Airport on the 22nd and 23rd marked the beginning of a protracted cold spell which lasted until the end of the month. The cloudy… Cold weather was accompanied by occasional light snow or flurries and fog. New record low temperatures for the dates were set on the 24th thru the 29th with the lowest temperature of 11 degrees below zero on the 28th. The seven consecutive days of low temperatures of zero or below had been exceeded in duration only 4 times previously. New low maximum temperatures for the dates were set on the 23rd… 24th…and the 26th thru the 29th with the lowest maximum temperature of 8 degrees recorded on the 26th.

25-26

In 1971…a wind gust to 100 mph was recorded in Boulder at the National Center for Atmospheric Research. The cold west winds gusted to 53 mph in downtown Boulder. No damage was reported. Northwest winds gusted to 31 mph on the 25th and to 38 mph on the 26th at Stapleton International Airport.

In 1984…a heavy snow storm left 1 to 2 feet of new snow in the foothills west of Denver. I-70 was closed…stranding skiers returning from the mountains. Most had to spend several hours in Idaho Springs. The snow spread over metro Denver with 9 inches at Littleton…Castle Rock…and Boulder and up to 5 inches in Aurora and Denver. Snowfall totaled only 3.6 inches at Stapleton International Airport where north winds gusted to 31 mph.

In 1954…strong Chinook winds gusting to 52 mph during the morning warmed the temperature in Denver to a balmy 65 degrees by early afternoon. A vigorous Canadian cold front during the late afternoon produced north winds at sustained speeds of 52 mph with gusts as high as 65 mph and billows of blowing dust…which reduced the visibility to as low as 1 mile at Stapleton Airport. Showers left half an inch of snow on the ground as the temperature dipped to a low of 27 degrees before midnight.

In 1989…a brief rain shower produced a microburst wind gust to 51 mph at Stapleton International Airport.

Storm totals included: 12 inches near Black Mountain and Pine Junction…10 inches near Conifer and Nederland; 9 inches…12 miles northwest of Golden; 8 inches near Evergreen…with 6 inches near Eldorado Springs. Snow and blowing snow produced blizzard conditions along and south of the Interstate 70 corridor…just east of Denver.  Storm totals generally ranged from 3 to 7 inches. North winds of 25 to 30 mph were reported with gusts around 40 mph. Roads became impassable as snow and blowing snow produced 3 to 4 ft snow drifts. Interstate 70 was closed from Aurora to the Kansas state line. At Denver International Airport…a peak wind gust to 31 mph was reported along with 1.0 inch of snow.

26-27

In 1893…heavy snowfall totaled 7.9 inches in downtown Denver. Most of the snow…6.7 inches…fell on the 27th. Northeast winds were sustained to 18 mph with gusts to 30 mph behind an apparent cold front.

The trailer left the road surface…and collided with the top left side of the first car; causing extensive damage. A van following the first vehicle then struck the trailer. The driver of the van suffered facial injuries. » Click here to read the rest of February 26 to March 4: This Week in Denver Weather History

Denver sets record low maximum for February 23

Thursday, February 23rd, 2023 11:59pm MDT

Record Cold Temperatures

Two very cold days and a third cold weather record has been set with this latest Arctic blast.

As measured at Denver International Airport, the Mile High City’s high temperature today topped out at only 7 degrees. This easily breaks the previous record low maximum for the date of 10 degrees set in 1874.

Here in Thornton, we were able to see the mercury climb a bit higher topping out at 13 degrees.

The record low maximum follows on the heels of record low temperatures set today and yesterday.

Bitter cold remains in Thornton on Thursday, slight chance for a touch of snow

Thursday, February 23rd, 2023 5:10am MDT

Oh yeah, just a little bit chilly out there. As of this writing at 4:00am, Thornton was down to -9 degrees and it may be even colder by the time you read this. We will see some relief today but not much.

Mostly sunny skies start us off and will be with us till this afternoon when cloud cover will increase some. Late afternoon brings a slight chance to see a few flurries / light snow. Minimal accumulations are expected. Temperatures today will only top out in the mid to upper teens.

Tonight, some light snow will be possible until about 10:00pm. Again, only light accumulations, if any, are expected. After that partly clear skies will be above and we will be headed toward an overnight low into the single digits.
