Thornton’s weekend offers up a couple pleasant days, ends on the wet side

Given the beautiful start to the three day period, it will be hard to complain about the way it ends. We can certainly use the moisture that is to come.

Friday offers up conditions much like we have seen the last couple of days. We will enjoy sunny skies with temps in the low to mid-60s. Tonight, cloud cover will increase and lows will dip to the mid-30s.

Saturday will see a few more clouds but will be the warmest day of the period. Look for highs in the mid to upper 60s under mostly sunny skies. Saturday night, cloud cover will again increase. Lows will be in the mid-30s.

Sunday, a system moves in and cools us down and should get us wet. The morning will offer only a slight chance for showers then they will become more widespread and stronger in the afternoon. Sunday night, depending on how quick temperatures drop, we may see some snow. At this time, it doesn’t look like it will amount to much. Maybe an inch or two by Monday morning.

Have a great weekend!

March 17 to March 23: This Week in Denver Weather History

This Week in Denver Weather History

March weather can be gorgeous but it can also be nasty with a healthy dose of any of the four seasons. Our look back at this week highlights this with a number of notable weather events from powerful, damaging winds to landspout tornadoes and of course monstrous snow storms.

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.

17

In 1966…high winds caused extensive minor damage across metro Denver. A light plane was overturned at Stapleton International Airport where northwest wind gusts to 55 mph were recorded. Winds gusted to 56 mph at Table Mesa in Boulder

In 1989…strong winds raked metro Denver. West wind gusts to 49 mph were clocked at Stapleton International Airport.

In 2003…the first tornado of the season was sighted near Strasburg. The small landspout touched down briefly…but caused no damage.

17-18

In 1923…4.2 inches of snow fell over downtown Denver. Northwest winds were sustained to 45 mph with gusts to 49 on the 17th. Low temperature of zero degrees on the 18th was the lowest of the month that year.

In 1944…heavy snow fell across metro Denver. The storm started as rain on the 17th…but soon turned to snow. Snowfall amounts totaled 8.5 inches in downtown Denver and 11.0 inches at Stapleton Airport. The highest wind recorded during the storm was 23 mph on the 17th.

In 1961…a major winter storm dumped 10.7 inches of snow at Stapleton Airport. Most of the snow…9.7 inches…fell on the 18th. Winds were light.

In 1994…strong winds buffeted metro Denver. West winds gusted to 51 mph at Stapleton International Airport on the 17th. Other significant wind gusts included 85 mph atop Squaw Mountain south of Idaho Springs…and 82 mph at Rollinsville southwest of Boulder…both on the 18th.

In 1996…a second storm in less than 3 days dumped heavy snow in the mountains and foothills again…but snowfall amounts across metro Denver ranged from only 2 to 4 inches. The heavy snowfall resulted in several traffic accidents along I-25 and I-70…south and west of Denver respectively. The major accidents involved at least 30 cars and resulted in several minor injuries. The accidents closed both highways for a time. Snowfall totals included 13 inches at Evergreen and 10 inches at Conifer. Snowfall totaled only 0.7 inch at the site of the former Stapleton International Airport. At Denver International Airport… North winds gusted to 28 mph on the 17th and 39 mph on the 18th.

In 2016…a combination of enhanced banding associated with a strong upper level jet stream…and low level upslope following the passage of a cold front…produced heavy snowfall in northern mountains as well as in and near the foothills of Boulder County. Storm totals included: 19.5 inches near Ward…16 inches near Allenspark…13.5 inches near Eldorado Springs; 13 inches at the National Weather Service Office in Boulder and 5 miles east of Boulder; 12.5 inches at Winter Park Ski Resort…12 inches at Eldora Ski Area; 11 inches…7 miles south of Lyons and at Rollinsville; 10.5 inches at Aspen Springs… and 9.5 inches near Blackhawk. In Denver and the surrounding suburbs…storm totals included: 8.5 inches in Broomfield…Lafayette and 5 miles northeast of Westminster; 7 inches near Northglenn…6.5 inches in Thornton and northwest Denver; with 6 inches at Firestone. At Denver International Airport…an official measurement of 4.7 inches of snow was observed.

17-19

In 1933…rain changed to snow on the evening of the 17th and continued through mid-day of the 19th. Snowfall totaled 5.6 inches with 0.83 inch of precipitation in in the city. North winds were sustained to 38 mph with gusts to 46 mph on the 18th and to 30 mph with gusts to 43 mph on the 19th.

In 2003…one of the worst blizzards since historic records began in 1872 struck metro Denver with a vengeance. Heavy wet snow accumulating to around 3 feet in the city and to more than 7 feet in the foothills brought transportation to a near standstill. North winds sustained to 30 mph with gusts as high as 41 mph produced drifts to 6 feet in the city. The estimated cost of property damage alone…not including large commercial buildings…was 93 million dollars… Making it the costliest snowstorm ever. Mayor Wellington Webb of Denver said…”this is the storm of the century…a backbreaker…a record breaker…a roof breaker.” Two people died in Aurora from heart attacks after shoveling the heavy wet snow. The National Guard sent 40 soldiers and 20 heavy duty vehicles to rescue stranded travelers along I-70 east of Gun Club Road. The heavy wet snow caused roofs of homes and businesses to collapse. The snow also downed trees… Branches…and power lines. Two people were injured when the roofs of their homes collapsed. In Denver alone…at least 258 structures were damaged. In Arvada…a roof collapse at west gate stables killed a horse. Up to 135 thousand people lost power during the storm…and it took several days for power to be restored in some areas. Denver International Airport was closed…stranding about 4000 travelers. The weight of the heavy snow caused a 40-foot gash in a portion of the tent roof…forcing the evacuation of that section of the main terminal building. Avalanches in the mountains and foothills closed many roads…including I-70…stranding hundreds of skiers and travelers. Along I-70…an avalanche released by the Colorado department of transportation…blocked the interstate in both directions for several hours. Several residences between Bakerville and Silver Plume were evacuated because of the high avalanche danger. At Eldora Ski Area…270 skiers were stranded when an avalanche closed the main access road. After the storm ended…a military helicopter had to ferry food to the resort until the road could be cleared. The heavy snow trapped thousands of residents in their foothills homes in Jefferson County for several days. Two homes burned to the ground when fire crews could not reach the residences. Some schools remained closed well into the following week. The storm officially dumped 31.8 inches of snow at the site of the former Stapleton International Airport…the most snowfall from a single storm since the all-time record snowfall of 37.5 inches on December 4-5…1913. The storm made March 2003 the snowiest March on record…the 4th snowiest month on record… And the 5th wettest March on record. The 22.9 inches of snow on the 18th into the 19th was the greatest 24 hour snowfall ever recorded in the city during the month of March. The storm was also a drought-buster…breaking 19 consecutive months of below normal precipitation in the city. Snowfall across metro Denver ranged from 2 feet to more than 3 feet. The highest amounts included: 40 inches in Aurora…38 inches in centennial and 6 miles east of Parker…37 inches at Buckley AFB…35 inches in southwest Denver…34 inches in Louisville… 32 inches in Arvada…31 inches in Broomfield and Westminster… And 22.5 inches in Boulder. In the foothills…snowfall ranged from 3 feet to more than 7 feet. Some of the most impressive storm totals included: 87.5 inches atop Fritz Peak and in Rollinsville…83 inches at cabin creek…74 inches near Bergen Park…73 inches northwest of Evergreen…72 inches in Coal Creek Canyon…70 inches at Georgetown…63 inches near Jamestown…60 inches near Blackhawk…55 inches at Eldora Ski Area…54 inches 8 miles west of Sedalia…and 46.6 inches at Ken Caryl Ranch. The storm was the result of a very moist…intense slow moving pacific system which tracked across the four corners and into southeastern Colorado…which allowed deep easterly upslope flow to form along the Front Range.

18

In 1883…0.3 inch of snow fell in downtown Denver. This was the only measurable snowfall of the month.

In 1903…rain changed to sleet and then to snow…which became heavy. Post-frontal snowfall totaled 7.0 inches over the city. North winds were sustained to 51 mph with gusts as high as 60 mph.

In 1905…northwest winds were sustained to 42 mph.

In 1914…northeast winds were sustained to 46 mph with gusts to 56 mph behind a strong cold front. Snowfall was 3.4 inches over the city…but most of the snow melted as it fell. The estimated amount of melted snow was 8.1 inches.

In 1920…a terrific windstorm occurred along the eastern foothills. Two deaths were attributed to the storm and some damage occurred. Both Denver and Boulder were affected by the strong winds. West winds were sustained to 51 mph with gusts as high as 66 mph in downtown Denver. The strong winds did considerable damage to property… Wires…plate glass windows…and indirectly loss by fire. The wind caused the death of one young girl by toppling the side of a brick building on her as she was standing on a corner waiting for a car. The wind was also responsible for several severe auto accidents due to blowing debris into the streets and blowing dust and dirt into the eyes of drivers.

In 1954…west winds at sustained speeds of 40 mph and gusts as high as 56 mph produced some blowing dust at Stapleton Airport.

The first day of spring in Thornton offers up mild temps, lots of sun

The changing of the seasons is here! Spring officially begins at 9:06pm tonight and we will say goodbye to winter with a fine looking day.

Sunny skies start us off and will be with us the majority of the day. The late afternoon and evening will bring just a few clouds. Overall, conditions will be calm and dry as we head for a high in the mid-60s.

Tonight, partly cloudy skies will be above and conditions remain calm. Overnight lows will be in the low to mid-30s.

Last week’s snowfall totals from the storm highlight an ongoing issue

Denver's March 14 & 15, 2024 Snowfall Totals. (National Weather Service)
Denver’s March 14 & 15, 2024 Snowfall Totals. (National Weather Service)

We all know our Pi Day storm last week was a big one.

Here in Thornton we recorded 10.8 inches. Downtown Denver reported 12.2 inches.

What will Denver’s official snow records show? A mere 5.7 inches. This is a direct result of the National Weather Service’s insistence on having Denver’s official measurements taken at Denver International Airport.

Data was collected in downtown Denver from 1872 through December 1948, then at the Stapleton Airport Office from January 1950 through February 1995. In March 1995, the service made the station at DIA the city’s official station for most meteorological observations. In 2008, they began taking official snowfall measurements out there.

Being so far from the Mile High City’s population center, the data collected there is entirely unrepresentative of what residents experience. Further, the move has skewed our climate records rendering comparisons to historical data invalid.  It is highly frustrating and is a significant issue which the National Weather Service dismisses.

Local television meteorologists have long railed against the change in station, most notably Mike Nelson of Denver 7. With this storm, Ashton Altieri of CBS 4 called the National Weather Service out on it.

Calm, dry conditions start off Thornton’s workweek

Well, going back to work might not be ideal but at least Mother Nature is serving up a pleasant day of weather as you do. We will enjoy lots of sun above today with temperatures right close to average for the date.

Look for sunny skies above throughout the daytime hours. Overall, conditions will be calm and we will remain dry. High temperatures will be topping out in the mid-50s.

Tonight, lows dip to a bit below freezing under mostly clear skies.

After the storm, conditions improve for Thornton’s weekend but remain chilly

That’s a wrap on our Pi Day storm. Thornton had a two day total of 10.8 inches of heavy, wet snow. Certainly, there were the haves and have-nots with some folks not far from Thornton Weather HQ receiving much less.

For Friday, we may see a few more flakes early but then snow will end and we will see a little bit of sun. High temperatures will top out around 39 degrees. Tonight, fog is expected to develop with partly clear skies. Lows will dip to the low to mid-20s.

Saturday will see fog initially, then some blue sky with mostly sunny skies above. It will remain cool with highs in the low to mid-40s. Saturday night, a weak system brings just a slight chance of rain / snow showers but no drama is expected. Lows will be around 30 degrees.

Sunday we warm further but will see more clouds. Look for highs in the mid-40s under partly sunny skies.

Thornton’s Pi Day storm arrives, snow to continue throughout the day

Going to bed last night we were a bit worried about the changeover from rain to snow but it did occur. We will now see the snow continue through the day with conditions deteriorating.

Last night we received 0.65 inches of rainfall before the transition. Now, as of this writing, we have 2.4 inches of snow on the ground with light to moderate showers ongoing.

Snow will continue throughout the day with, perhaps, a bit of a lull this morning, then picking back up in the afternoon and evening. After midnight, things will begin to taper off.

The Winter Storm Warning remains in effect until 6:00am Friday with the National Weather Service calling for 10 to 18 inches for the Denver metro area. We continue to think 8 to 12 inches is likely for Thornton by the time this is done tomorrow morning.

Obviously, you should not venture out unless you truly need to. Better to stay safe and indoors. Travel will be hazardous, and the snow may cause some power outages and property damage.

We’ll have more updates throughout the day but our Winter Weather Briefing Page is your one-stop shop for the latest.

Across the Palmer Divide and northeast plains of Colorado…storm totals ranged anywhere from 2 to 10 inches. The combination of snow and strong wind produced blizzard conditions and forced the closure of Interstate 70 east of Denver. Sustained winds of 25 to 35 mph with gusts to 45 mph produced near zero visibilities at times and snowpacked roads. Snowdrifts from 2 to 4 feet deep were reported. As a result…many of the roadways became impassable. Officially…Denver International recored 5.4 inches of snowfall on the 9th. In addition…a peak wind gust to 38 mph was observed from the north.
