January 12 to January 18: This Week in Denver Weather History

Sunday, January 12th, 2020 5:49am MST

This Week in Denver Weather History

High winds are in many ways the most common extreme weather event in January as they frequently rake the foothills this time of year. Our look back at this week in weather history shows many such damaging events. There are also of course snowstorms and examples of extreme cold.

From the National Weather Service:

10-12

In 1997…heavy snow fell over the Front Range foothills. A foot of new snow was measured at Blackhawk with 7 inches recorded in Coal Creek Canyon. Only 3.3 inches of snow fell at the site of the former Stapleton International Airport. East-northeast winds gusted to 18 mph at Denver International Airport on the 11th.

10-13

In 1963…an arctic cold wave plunged temperatures well below zero across metro Denver. Temperatures were below zero for a total of 64 consecutive hours. Low temperatures reached 25 degrees below zero on both the 11th and 12th. The high temperature of 9 degrees below zero on the 11th was the coldest ever recorded at Stapleton Airport and equaled the record low maximum for the month first set on January 19…1883…in downtown Denver. The high temperature on the 12th reached only 1 degree below zero. On the 12th…an 18-year-old youth died of exposure from the extreme cold in Denver. There were many losses and damage to property from frozen water systems…stalled cars…and over-burdened heating systems. Light snow accompanied the arctic blast. At Stapleton Airport…2.3 inches of snow fell on the 10th and 11th.

11-12

In 1972…high winds howled along the Front Range foothills. A wind gust to 144 mph was recorded at the National Center for Atmospheric Research in Boulder. A wind gust to 105 mph was recorded at the Rocky Flats plant south of Boulder. Wind gusts to 90 mph were recorded in downtown Boulder. The greatest damage from the windstorm occurred in Boulder where 25 or more mobile homes were destroyed either by wind or the fires which resulted when they were overturned. Car windows were blown out; many buildings damaged; utility poles…power lines…trees…and traffic lights blown down. As many as 75 families were evacuated from a recently completed apartment building because of severe structural damage. Government and private office buildings and industrial plants were evacuated because of danger from flying glass and debris. Twelve people were treated at the hospital…mostly for cuts from flying glass. At least 15 small planes were seriously damaged and hangar doors were blown off at the Jefferson County Airport in Broomfield. Wind damage in Boulder alone totaled 2 million dollars. At Stapleton International Airport…west winds gusted to 53 mph on the 11th and to 47 mph on the 12th. The strong Chinook winds warmed temperatures into the mid 50’s on both days.

11-14

In 1997…cold arctic air plunged temperatures below zero across metro Denver. The temperature was below zero for 60 consecutive hours from the afternoon on the 11th to around daybreak on the 14th.

Eleven inches fell at Lake Eldora west of Boulder…with 7 inches recorded at Morrison and 6 inches at Castle Rock. At Stapleton International Airport where north winds gusted to 31 mph…the snowfall totaled only 4.4 inches. Strong winds forced the closure of some highways.

In 1998…very strong winds and heavy snow caused blizzard conditions in the mountains to spread over portions of the Front Range foothills. Just east of the Continental Divide…sustained winds from 80 to 85 mph with gusts to 100 mph were recorded at Silver Spruce Ranch near Ward… Resulting in whiteout conditions. Only a trace of snow fell at the site of the former Stapleton International Airport. North winds gusted to only 28 mph at Denver International Airport.

In 2009…a fast moving storm system brought heavy snow to the foothills of Boulder and Jefferson counties…as well as the western and southern Denver suburbs. Storm totals generally ranged from 4 to 9 inches. The snowfall measurement at Denver International Airport was 3.0 inches.

12-13

In 1936…strong winds in Boulder blew roofs off homes. Wind gusts over 60 mph were recorded at the University of Colorado and a gust to 55 mph measured at Valmont.

In 1932…snowfall totaled 3.4 inches in downtown Denver. North winds gusted to 22 mph.

In 1967…high winds in Boulder gusted to 70 mph downtown. Some damage occurred. Northwest winds gusting to 38 mph at Stapleton International Airport produced some blowing dust.

The wind suddenly veered to the southwest and the temperature climbed 19 degrees in 15 minutes…7 more degrees in the next 5 minutes…and by 9:30 pm had risen to 36 degrees. By 9:35 pm the temperature had reached 40 degrees…a rise of 48 degrees in one hour and 39 degrees in half an hour. The sudden rise in temperature could be attributed to a receding arctic air mass and downsloping surface winds.

Thornton’s weekend starts chilly, will warm to near normal, offer some wind

Friday, January 10th, 2020 5:01am MST

The “storm system” that moved through last night, was, well, a dud. Other than some cold, we will see nothing from it and Saturday and Sunday will warm right back up to see typical temperatures for this time of year.

For Friday, partly to mostly sunny skies will be above. Temperatures will be chilly with highs in the mid-30s. Winds will be a little bit breezy throughout the day. Tonight, mostly clear skies will be above with lows dropping into the mid-teens.

Saturday will be the most pleasant day of the three day period. Mostly sunny skies will be above with high temperatures in the mid to upper 40s. Winds may turn a bit breezy in the afternoon. Saturday night into Sunday morning, temperatures will drop to the low 20s under partly clear skies.

We close out the weekend on Sunday with temperatures right near the average high for the date of 44 degrees. Mostly sunny skies will be above. Unfortunately, winds look to be a bit breezy for much of the day.

Thursday sees temps cool to normal levels, overnight may bring some snow

Thursday, January 9th, 2020 5:04am MST

A bit of a change in the weather as a series of disturbances looks to mix things up a bit in the coming days. The change will not be dramatic, however, offering up cooler temperatures and just a bit of a chance for snow.

Today starts with mostly to partly clear skies and then slowly increasing cloud cover as the day progresses. We will cool quite a bit from the unseasonably warm temperatures but only to readings close to the average high for the date of 44 degrees.

Tonight, skies will be mostly cloudy with overnight lows around 20 degrees. Light snow will be possible from about 8:00pm into tomorrow morning. There isn’t much moisture to work with so we are looking at only a trace to maybe an inch if we are lucky.

Thornton will enjoy a warm Wednesday aided by downslope winds

Wednesday, January 8th, 2020 4:54am MST

With forecast high temperatures almost 15 degrees above normal, we will enjoy a mild day. Driving those temps though will be some breezy downslope winds which might limit your enthusiasm.

We start out with a bit of cloud cover but it will ease as the morning and early afternoon progress. Winds will be light this morning then pick up the pace around noon-time and continue into the evening.

We should avoid any strong gusts but could see some readings up to 25mph or so. The wind will help drive temps up leading to highs in the upper 50s.

Tonight, mostly clear skies will be above with lows in the mid-20s.

Keep an eye on the temps and winds here.

Tuesday starts with wind but the blowing will ease, temps will be well above normal

Tuesday, January 7th, 2020 4:56am MST

The wind of the last 36 hours or so is blowing its last breath this morning. As it starts to die down, we will see a day with a good bit of sun and very mild temperatures.

Clear skies start us off and by late morning a few clouds will arrive giving mostly sunny skies in the afternoon. Breezy winds are going to continue early but by mid to late morning they will ease. High temperatures today will be in the mid to upper 50s, well above the average high for the date of 44 degrees.

Tonight, partly cloudy skies will be above with lows in the mid-20s.

Thornton’s workweek starts with seasonal temps but wind will be along for the ride

Monday, January 6th, 2020 5:07am MST

Normally, sunny skies and temps near normal would be something to be happy about. Today, however, with gusty winds expected throughout the day, your enthusiasm about the weather will be lessened.

Clear skies start us off and will be with us throughout the day. Temperatures start on the cold side but will warm to a high right near the average for today’s date of 45 degrees.

The main story today will be the wind which is already blowing pretty good and will continue through the day. Gusts pushing toward 40mph will be possible.

Tonight, the wind will ease some after about 8:00pm but remain a bit breezy. Skies will be mostly clear with lows in the mid-20s.

December 2019 weather recap: Warmer than normal temps, little snowfall

Sunday, January 5th, 2020 7:42am MST

We closed out 2019 with a change from the cool, wet conditions of the previous two months. December saw the opposite conditions as average temperatures were above normal and snow a rarity.

Storm systems did move through Colorado and the Rocky Mountain region and while the high country saw plenty of snow, these storms evaded the Front Range for most of the month. Temperatures were never particularly warm but overall, the average temp was warmer than normal in Thornton.

On the 5th of the month, we saw a respectable bit of rain instead of snow. Finally, a light snowfall on the 14th was the first snow of the month. We then stayed dry until the 28th when we received our first – and only – appreciable snowfall of the month.

Thornton’s overall average temperature for the month came in at 31.9 degrees. This was a good bit warmer than Denver’s long term average for December of 30.0 degrees. Out at Denver International Airport where the Mile High City’s official records are kept, it was warmer with an average of 33.7 degrees.

Temperatures in Thornton ranged from a high of 64.6 degrees on the 22nd down to a low of 7.2 degrees on the morning of the 30th. Denver recorded a maximum of 67 degrees and its minimum of 3 degrees on the same dates.

In terms of precipitation, Denver averages 0.35 inches during December. Thornton fell short of that with 0.28 inches while Denver had just a touch more with 0.30 inches.

A mere 2.8 inches of snow was recorded in Thornton during the month and Denver had an identical number. These were well short of the 8.7 inches December typically brings.
