Well, the storm didn’t pan out to be quite as big as hoped but we still got a respectable amount. As of 4:00am, Thornton was at 4.2 inches and more is to come.

Look for snow to continue through the morning before gradually tapering off through the afternoon. An additional 1 to 3 inches will be possible. High temperatures today will top out at only around the 30 degree mark. Winds will be blustery this morning.

Tonight, skies will clear and we will have a very cold night with lows around 12 degrees.

Old Man Winter is at the ready and tonight he will likely deliver our most significant storm of the season thus far. A Winter Storm Warning has been issued and folks should get their preparations wrapped up ASAP.

The day starts off nice enough with mostly sunny skies but cloud cover will steadily increase through the morning and early afternoon. Highs will only be topping out in the mid-30s.

A few flurries / light snow may start as early as 3:00pm or so. The snowfall arrives in earnest around 6:00pm and will continue through much of tomorrow morning.

• Winter Weather Briefing Page

Overnight, snow will be heavy at times with 5 to 8 inches expected before dawn tomorrow. An additional 1 to 3 inches will be possible tomorrow morning. There is an outlying possibility those totals end up even higher.

Needless to say, with numbers like that, travel overnight and tomorrow will be difficult, if not nearly impossible. If this plays out as expected, do not venture out if you don’t need to.

The proverbial calm before the storm as we enjoy a rather nice day Monday. Late in the day Tuesday, big changes are afoot.

For today, mostly sunny skies will be with us throughout the day. Overall, conditions will be calm and dry. Look for highs right near the average high for the date of 45 degrees, perhaps a couple degrees warmer.

Tonight, skies will be partly cloudy and lows will dip to the low 20s.

As we have been discussing, the focus right now is on the winter storm set to arrive tomorrow afternoon / evening. A Winter Storm Watch has been issued as significant snowfall from Tuesday evening through Wednesday will be possible.

The National Weather Service is cautioning that 5 to 10 inches will be possible. Here in Thornton, we do see the potential for 4 to 7 inches. Most notable impact will be to your Wednesday morning commute which may be a rough one.

We are still 36 hours out and things can change but you should definitely get yourself prepared today.

A relatively calm weekend ahead for us. Friday and Saturday will be somewhat mild with mercury readings above normal. A weak system moves in on Sunday that cool us down and bring just a bit of a chance for snow.

For today, mostly sunny skies will be above and conditions calm. Highs will top out close to the 50 degree mark. Tonight, lows dip to the upper 20s under mostly cloudy skies.

Saturday sees an increase in cloud cover above but it will remain calm. Look for highs in the low 50s. Saturday night, skies remain mostly cloudy and lows will be in the mid-20s.

Sunday cools down a bit with highs around 45 degrees. Daytime hours may see some light rain or snow showers. Sunday evening, chances for snow increase but minimal, if any, accumulation is expected.

A pleasant winter’s day ahead for Thornton. We will enjoy plenty of blue above and temps will be right near average for the date.

We start off with mostly sunny skies but the few clouds will soon ease and most of the rest of the day will be largely clear. Conditions will be calm and dry. High temperatures will top out near the average high for the date of 45 degrees.

Tonight, lows will drop to the low to mid-20s under mostly clear skies.

Enjoy!

A glancing blow from a weak system mixes our weather up a bit today. It will be colder and while we stand a chance for some precipitation, we aren’t expecting much.

Mostly cloudy skies will be with us throughout the daytime hours. Winds will be light and out of the north. High temperatures will top out around the 40 degree mark.

There will be varying chances for snow this morning with the best opportunity coming between about 8:00am and 11:00am. This afternoon, chances decrease and if there is precipitation, there may be some rain mixed in. At this time, only minimal accumulations of snow are expected, if any at all.

Tonight, any precipitation will end in the early evening. Skies will clear a bit and overnight lows will dip to around 20 degrees.

You can keep an eye out for showers with our interactive radar here.

A bit more help melting off the snow and ice today. Breezy downslope winds will help drive a mild day.

The day starts with some cloud cover but overall we will enjoy mostly sunny skies with a trend toward clear skies later in the day. Winds will initially be calm but then pick up the pace later this morning. It will be quite from mid-day through the afternoon. Those winds will help warm temperatures though with highs in the mid-50s expected.

Tonight, cloud cover will increase and overnight lows will dip to the mid-20s.

Our next storm system moves in late tonight / early tomorrow but at this time we aren’t expecting much from it. It will be colder tomorrow and snowfall will be quite light.

Downslope winds early kept us relatively warm in the pre-dawn hours. That will help give us a head start toward a day with temps a good bit above normal.

Mostly clear skies start us off. Cloud cover will see a gradual increase throughout the day but without being overly intrusive. Winds will be a bit breezy and out of the southwest this morning. High temperatures today will top out in the mid-50s, a good bit above our average high for the date of 45 degrees.

Tonight, clouds will increase and it will be a little bit breezy. Overnight lows will be in the mid-20s.

January in Colorado is known for two main weather conditions – cold and wind. Our look back at this week in Denver weather history shows why this reputation is well earned.

From the National Weather Service:

7-8

In 1911…gale force winds occurred in Boulder causing minor injuries.

In 1937…cold arctic air plunged temperatures below zero for an estimated 56 consecutive hours. Two temperature records were set.

Low temperatures plunged to 12 degrees below zero on the 7th and 11 degrees below zero on the 8th. Snowfall was 1.4 inches in downtown Denver.

In 1969…a violent evening windstorm struck Boulder and the adjacent foothills. A wind gust to 130 mph was recorded at the National Center for Atmospheric Research. Winds reached 96 mph in downtown Boulder. The Boulder airport wind recorder was blown away after measuring a wind gust to 80 mph. The windstorm caused over one million dollars in damage and one fatality in Boulder. About 25 homes in south Boulder had roofs blown off or were severely damaged. Roofs were blown off buildings housing scientific laboratories and offices of the Environmental Science Services Administration…now NOAA…in Boulder…and installations of several scientific measuring sites near Boulder received heavy damage. Grass fires driven by the high winds endangered many areas…but were controlled by volunteer firemen. One man died from injuries received when he was blown from a fire truck. One man was killed and another injured when the truck camper in which they were riding was blown off I-25 about 10 miles north of Denver. In the same area a mobile home and a truck trailer were blown off the highway and demolished. At least 20 people in the Boulder area received light to serious injuries from flying debris or from being blown into obstructions. Power lines and trees were downed over a wide area. Damage was relatively light in the city of Denver…where northwest winds gusted to 62 mph at Stapleton International Airport on the 8th. Many windows were broken in Arvada…Englewood…and Littleton. A 27-year-old fire lookout tower on Squaw Mountain…west of Denver…was blown away…and several radio relay towers at that location were toppled. Trucks were overturned near Georgetown. Mobile homes were overturned in several areas with occupants receiving injuries in some cases. The strong Chinook winds also brought warm weather. The maximum temperature of 69 degrees on the 7th broke the old record of 65 degrees set in 1948. The temperature also reached 65 degrees on the 8th…but was not a record.

In 1992…an intense blizzard buried eastern parts of metro Denver. At times snow fell at rates of 2 to 3 inches an hour. Winds increased from the north at speeds of 25 to 45 mph. Drifts of 4 to 8 feet were common. I-70 was closed east of Denver…and I-25 was closed from Denver south. Snowfall totals ranged from a couple of inches in the foothills west of Denver to as much as 2 feet on the east side of metro Denver.

In 1990…high winds gusting from 50 to 90 mph along the Front Range produced much damage from blowing dust and gravel throughout the day. Wind gusts to 92 mph were recorded in the Table Mesa area of southwest Boulder. The winds caused sporadic power outages. Clouds of dust and gravel whipped by 70 to 90 mph gusts blinded commuters on the Denver-Boulder Turnpike near Broomfield during the morning rush hour. Flying gravel shattered windows on 50 vehicles parked near a Boulder high school. High winds were also blamed for partially dismantling a house under construction in Boulder…as well as toppling a number of fences…billboards…signs…and power poles. The strong cross-winds jack-knifed and overturned semi-tractor trailers on I-70 near Golden and just south of Boulder on State Highway 93. Several county airports were closed due to strong winds and blowing dust reducing visibilities. Wind delays up to 30 minutes occurred at Stapleton International Airport where west winds gusted to 48 mph. Eighty mph winds in Georgetown…Empire…and Idaho Springs were blamed for power and telephone outages. Windows were blown out of a sheriff’s car along I-70 east of Georgetown. The strong Chinook winds warmed the temperature to a high of 60 degrees in Denver.

In 2007…strong winds associated with an intense upper level jet…and a very strong surface pressure gradient…developed in and near the Front Range foothills. Peak wind gusts ranged from 77 mph to 115 mph. The strong winds coupled with freshly fallen snow resulted in whiteout conditions and several highway closures due to blowing and drifting snow. Road closures included: State Highway 93 between Golden and Boulder; State Highway 128 from Wadsworth Boulevard to State Highway 93; U.S. Highway 36…the Denver Boulder Turnpike from Broomfield to South Boulder Road; and State Highway 74 near Evergreen…between County Road 65 and Lewis Ridge Road. More than 100 people were stranded in their cars between Golden and Boulder as blowing and drifting snow made the highway impassable. Snow drifts along State Highway 93 were over 6 feet in depth. As a result… The American Red Cross opened a shelter at Arvada West High School for the stranded commuters. Up to twenty cars were also abandoned along the Diagonal Highway…between Boulder and Longmont. Thirty vehicles were stranded along State Highway 128. The high winds also caused intermittent power outages in Boulder. West winds gusted to 40 mph at Denver International Airport
