May 2014 weather recap: Temps near normal, a good bit wetter than normal

June 4, 2014 Thornton Weather Leave a comment

The month of May was a relatively benign, uneventful month in terms of the weather in Thornton. Average temperatures were right on par with normal while precipitation was generous.

We started out the month with warming temperatures and by the third we were seeing highs in the 80s. This only lasted a few days before cooler than normal temperatures settled in for a 10 day period.

It was during that period that we recorded precipitation for six straight days. This included a good shot of snow on the 11th and 12th.

Temperatures bounced back on the 18th and 19th with highs above 80 degrees but then settled down again to predominantly cooler than normal conditions for the next week. The period from the 20th to the 25th also saw a return to wet conditions.

Warmer and dry conditions returned for a few days and then we closed out the month with cooler temperatures and some more rain.

Thornton finished the month with an average temperature of 56.9 degrees. This was just a hair lower than Denver’s May average of 57.1 degrees. The Mile High City’s average temperature came in warmer at 57.5 degrees.

In terms of precipitation, Thornton saw a healthy 4.26 inches of liquid precipitation. This was well above the May average of 2.12 inches. Similarly, Denver saw above normal precipitation with a reading of 3.51 inches.

Snow fell on two days and totaled 4.3 inches in Thornton. Out at DIA, only 1.1 inches was recorded. Average snowfall for May in Denver is 1.1 inches.

Thornton’s June weather preview: Severe weather takes to the forefront

June 4, 2014 Thornton Weather Leave a comment

Thornton's June weather preview. Extreme weather can occur during in month in Colorado we well know. June however is when traditional spring severe weather arrives in the state oftentimes with hail, damaging wind and tornadoes.

Over 40 percent of the tornadoes that occur in Colorado happen during the month of June. Far more common are thunderstorms with hail and wind, each responsible for extensive damage each year.

While severe weather is common, so too are brilliantly sunny and mild days as we close out spring and enter summer. If you are looking for cold, it isn’t likely but it is possible as the Denver area has seen freezing temperatures and yes, even snow, during the month.

A look back at the most destructive tornado in Denver metro history: June 3, 1981 Thornton, Colorado

June 3, 2014 Thornton Weather 7 Comments

June 3, 1981 - An F2 tornado rips through the heart of Thornton, Colorado. (NCAR) — June 3, 1981 – An F2 tornado rips through the heart of Thornton, Colorado. See more images in the slideshow below.(NCAR)

June 3, 1981 appeared to be a pretty typical late spring day in the Denver metro area. Afternoon thunderstorms though would become a ‘perfect storm’ and soon the city of Thornton would find itself witness to a tornado that would go down in the Denver weather history books.

Five tornadoes would strike that day but one would become the most infamous. The Thornton tornado would tear through what was then the heart of the city damaging homes and businesses and sending many residents to the hospital.

The twister initially touched down at 2:43 p.m. and ripped across 2 miles of the city. The tornado was rated an F2 on the Fujita Scale packing winds up to 157mph.

Following is a description of the event from the National Weather Service and below that is a slideshow of some photos of the event we have accumulated.

In 1981…severe thunderstorms produced tornadoes over metro Denver. The first tornado touched down at the intersection of Alameda Ave. And Sheridan Blvd. The twister moved north along Sheridan Blvd….damaging businesses…apartment buildings…homes…and vehicles. Over ten homes were unroofed. The roof of one landed in the middle of a neighborhood park. At least 10 mobile homes were wrecked.

The tornado curved to the northeast into northwest Denver… Hopping up and down in several places. Very strong winds outside the actual funnel caused 20 to 30 thousand dollars in damage in downtown Denver. The third floor of one old building was demolished. No major injuries were reported from the tornado…although several people were hurt slightly in traffic accidents on Sheridan Blvd. in the confusion caused by the storm. Damage in Lakewood alone was estimated at 200 thousand dollars.

At the same time… The worst tornado to ever hit metro Denver struck Thornton. Coming from the same thunderstorm that spawned the Denver twister…the Thornton tornado tore a swath through the heart of the city. 87 homes were destroyed…110 others damaged at least moderately. In all…600 homes in a 100 block area sustained some damage. The twister also hit shopping centers…several restaurants…and other buildings. Seven of the 42 injured were considered serious. The storm was strong enough to snap lamp posts in half and drive a 6- inch slab of wood 2 feet into the ground. Damage was estimated at up to 50 million dollars.

The same storm that struck Thornton produced another damaging tornado that touched down in the northwest section of Fort Lupton. This twister damaged 16 homes and numerous cars and campers. Two children were slightly injured when the car they were in was knocked about and its windows shattered by the storm. The twister also damaged two commercial buildings. Damage was very spotty…and observers said the storm hopped up and down at least 3 times. Dollar damage was estimated at 500 thousand dollars.

The thunderstorm complex that produced 3 damaging tornadoes also dropped large hail which damaged many cars over northwest Denver. One to 2 inches of rain fell in less than an hour…flooding a mobile home park with 3 to 4 feet of water on the northwest edge of Denver. The high water damaged about half of the 392 homes in the park. Local flooding was also reported in other areas across metro Denver. A tornado was also sighted near Franktown…but caused no damage. A thunderstorm wind gust to 52 mph was recorded at Stapleton International Airport.
