Weekend offers mild temps Friday and Saturday, cold and wind Sunday

Friday, November 21st, 2014 5:32am MST

Thornton will have a bit of a mixed bag of weather over the next three days.  November’s reputation as our least sunny month will continue but at least offer two days of mild conditions.  Those will be followed by a blustery, cold Sunday.

For Friday we close out the workweek with mostly to partly sunny skies much like we have seen other days this week.  Temperatures will be climbing to a high of around 54 degrees.

Saturday continues to warm although clouds will be increasing their coverage.  Look for a high tomorrow around 58 degrees, almost 10 degrees above the average high for the date.

The state’s next weather maker moves in Saturday as well and that will bring a period of prolonged, possibly heavy, snow to the high country lasting into Monday.  Many areas are under watches and warnings so if you are heading to the high country, be sure to check conditions and forecasts first.

For us, we may see a few flakes late Saturday night but right now we aren’t expecting anything beyond that.  The system will bring colder temperatures and a good bit of wind on Sunday to the Front Range however.

The image has your weekend outlook and of course keep an eye on http://www.thorntonweather.com/ through the period for all the latest.

Thursday brings warmer temps despite increased clouds

Thursday, November 20th, 2014 5:16am MST

Our weather today looks to be quite a bit like yesterday’s. Temperatures will be a bit warmer despite a bit thicker cloud cover. We’ll start out the early morning quite cool but then climb to a high right around the average for the date of 50 degrees. Winds will be light throughout the day. Partly sunny skies will be above and may have a bit of an impact on those high temperatures.

This Week In Denver Weather History

November 16 to November 22: This Week in Denver Weather History

Snow certainly is common this time of year and we see many notable events featuring the white stuff in our look back at this week in Denver weather history. More prevalent however are significant wind events.

From the National Weather Service:


In 1964…the first measurable snowfall of the season totaled 6.0 inches at Stapleton International Airport where northeast winds gusted to 32 mph on the 14th. Most of the snow…4.2 inches…fell on the 14th. This was the only measurable snow of the month.


In 1894…winds behind an apparent strong cold front were sustained to 60 mph with gusts to 75 mph on the 15th. Snowfall totaled 2.6 inches in the city. Temperatures plunged from a high of 72 degrees on the 15th to a low of only 5 degrees on the 16th. The high temperature on the 16th was 24 degrees…which occurred shortly after midnight.

In 1996…around a foot of new snow fell in the foothills west of Denver with 3 to 6 inches at lower elevations across metro Denver. Some of the snowfall totals included: 15 inches at Georgetown…12 inches at Idaho Springs…10 inches at Chief Hosa…and 9 inches in Coal Creek Canyon. Snowfall totaled 2.9 inches at the site of the former Stapleton International Airport. Northeast winds gusted to 23 mph at Denver International Airport on the 16th.


In 1991…a strong winter storm dumped heavy snow over metro Denver. Snowfall amounts totaled 15 inches at Castle Rock and Conifer…14 inches at Morrison and Parker…12 inches in southeast Aurora…and 11.6 inches at Stapleton International Airport. Winds were light with the storm.

In 1899…a trace of rain fell in the city. This…together with a trace of precipitation on the 21st and 23rd…was the only precipitation of the month…making the month the driest on record. The record was equaled in November of 1901 and 1949.

In 1926…rain changed to snow behind a cold front and totaled 2.0 inches. North winds were sustained to 48 mph with gusts as high as 54 mph.

In 1930…strong winds occurred in Boulder causing minor damage. At Valmont just east of Boulder…winds gusted to 52 mph. West winds were sustained to 37 mph with gusts to 46 mph in downtown Denver.

In 1948…a west-northwest wind gust to 50 mph was recorded at Stapleton Airport.


In 2010…the combination of heavy snow and strong winds produced dangerous driving conditions in the high country. Blizzard conditions forced the closure of U.S. Highway 6 at Loveland pass and U.S. Highway 40 at Berthoud Pass. Blowing and drifting snow forced the closure of a 65-mile stretch of Interstate 70…west of Idaho Springs. Peak wind gusts included: 68 mph atop Niwot Ridge…55 mph near Blackhawk and Gunsight…and 52 mph at Berthoud Pass. Storm totals in the ski areas west of Denver ranged from 12 to 21 inches. Northwest winds gusted to 55 mph at Denver International Airport on the 16th.


In 1921…heavy snowfall totaled 6.5 inches over downtown Denver. This was the only measurable snow of the month. East winds were sustained to 14 mph on the 17th.


In 1948…a dry vigorous cold front accompanied by north winds gusting to 60 mph produced extensive blowing dust…which briefly reduced the visibility to 1/2 mile at Stapleton Airport.

In 1993…a wind gust to 70 mph was recorded atop Squaw Mountain near Idaho Springs.

In 1994…winds gusted to 66 mph in Boulder and to 63 mph on Rocky Flats south of Boulder. West winds gusted to 49 mph at Stapleton International Airport.

Snowfall totals included: 8.5 inches…7 miles south of Tiny Town; 6 inches at Genesee; and 5 inches…11 miles southwest of Morrison. Only a trace of snow was recorded at the site of the former Stapleton International Airport.


In 1869…the heaviest wind storm in 5 or 6 years raked the eastern foothills including Boulder…Denver…Georgetown… And Golden. Some hundreds of dollars in damage occurred in Boulder.


In 1872…fresh west winds contributed to the relative humidity dipping to zero at 2:43 pm. The maximum temperature was 54 degrees.

In 1907…heavy snowfall totaled 6.0 inches over downtown Denver. Snow fell all day. North winds were sustained to 19 mph.

In 1915…northwest winds were sustained to 42 mph with gusts as high as 48 mph. It was windy most of the day.

In 1996…high winds struck the foothills west of Denver. Wind gusts ranged from 70 to 75 mph. A few power lines were downed…but no major outages were reported.

In 1998…strong downslope winds developed during the morning. Wind gusts reached a peak of 72 mph at Jefferson County Airport near Broomfield. West winds gusted to 41 mph at Denver International Airport.

In 1999…high winds developed in and near the Front Range foothills. The strong winds downed power lines…which sparked several small brush fires.

Peak wind gusts included: 91 mph atop Blue Mountain near Wondervu…88 mph atop the Gamow Tower on the University of Colorado campus in Boulder… 83 mph at Jefferson County Airport…81 mph at the National Center for Atmospheric Research mesa lab above Boulder…and 80 mph at Wondervu.

Seasonal, calm conditions for Thornton’s Wednesday

Wednesday, November 19th, 2014 5:21am MST

Hump Day is going to offer relatively nice weather for us today.  Temperatures will again approach seasonal normals and we should see a good bit of sun above.

We start out the morning with mercury readings right around freezing as downslope winds helped to keep things relatively warm.  As the day progresses the temperature will be climbing to a high of around 48 degrees, right near the normal for the date of 50 degrees.  Mostly to partly sunny skies will be above and winds should be lighter than they were yesterday.

Look for comparable conditions to last through Saturday.  After that, another storm system moves in with colder temps and chances for snow.

Downslope winds to help bring first day of normal temps in more than a week

Tuesday, November 18th, 2014 5:16am MST

It has been just over a week since Thornton has seen temperatures at or above normal.  Today, thanks to some breezy downslope winds, we should finally see the mercury climb to right near average for the date.

We start out with clear skies.  Clouds will be increasing after about 9:00am and by this afternoon mostly to partly sunny skies will be above.

Winds will gradually be increasing but the worst will be to our west in the foothills.  Here in our area, look for 10mph winds with gusts to around 20mph by early to mid-afternoon.

Those downslope winds are going to help push temperatures up as we look for a high right at or perhaps a degree or two above the normal of 51 degrees.

Have a great day and keep an eye on the temperature and wind speed here.

Plenty of sun, warmer temperatures start Thornton’s workweek

Monday, November 17th, 2014 5:13am MST

Gradual warming will be the rule for much of the week along the Colorado Front Range.  The mercury readings however are going to continue to fall short of average for this time of year.

Starting things off today we will have sunny skies above followed by just a few clouds later in the day.  Temperatures will be climbing to the upper 30s, a marked improvement over past days but well short of the average of 53 degrees.  Gusty winds are expected to develop in the mountains and foothills but we could see things pick up a bit in our area this afternoon too.

Looking ahead, the 40s await Tuesday through Saturday but unfortunately likely with some wind accompanying the warmer temperatures on some of those days.  The next storm system moves in late Saturday and that will cool things back down Sunday and bring a slight chance for snow.

The image has your planning forecast for today and our main page has all the latest as usual.

Chilly Friday to be followed by snow Saturday and more cold

Friday, November 14th, 2014 6:12am MST

We won’t be breaking out of the Arctic chill anytime soon.  While we should see a good bit of sun today and Sunday, temperatures are going to remain well below normal and Saturday may offer some light snow.

For today look for mostly to partly sunny skies throughout the day.  Temperatures will climb to just a bit above freezing which is nearly 20 degrees below normal.

Our next storm system moves in tonight and will result it bitter cold and possibly snow.  Some flurries will be possible in the early morning hours Saturday with better chances for accumulating snow late tomorrow morning into the evening.

At this time, accumulations, if any, look to be light.  Our high temperature of 18 degrees Saturday is going to be reached early in the morning. After that, the mercury will be dropping and by the evening single digit temperatures return.

The system moves out Saturday night and Sunday morning.  In its wake, Sunday sees a return of the sun and dry conditions but temperatures will be topping out right near freezing.
