Typically November is a quiet weather month with plenty of nice, fall days but it can also turn wet with healthy doses of snow and moisture.  The wide variety of conditions can create picturesque scenes ranging from blue skies and snow-capped mountains to a wintry wonderland in the metro area.

November is the second snowiest month of the year so winter conditions are not unusual.  Typically though, these bouts of cold are short-lived and normal daytime conditions are pleasant.

Outdoor activities continue to be quite popular during the month.  The cooling temperatures do oftentimes lead to an increase in wildlife activity.

All of the above help lead to a month in which a wide variety of scenes, flora and fauna can be captured.

Time to “fall back” as Daylight Saving Time ends Sunday, November 6

Leave a comment
The United States returns to Standard Time at 2:00am Sunday as Daylight Saving Time comes to an end.
The United States returns to Standard Time at 2:00am Sunday as Daylight Saving Time comes to an end.

The biannual ritual of changing our clocks to adjust for Daylight Saving Time occurs this weekend, providing yet another signal of the changing of seasons.  The United States will ‘fall back’ one hour at 2:00am Sunday morning as we return to Standard Time.

The ritual of changing our clocks twice a year can be met with some resistance as some people struggle to adjust their body’s internal clock.  Others actually like the return to standard time as they get to enjoy an extra hour of sleep.

The time change definitely has big effects on the dawning of daylight and how early it gets dark in the evening.

Sunrise on Saturday occurs at 7:33am but on Sunday it will be at 6:34am. Similarly, sunset will occur at 5:53pm on Saturday but on Sunday the sun will disappear over the horizon at 4:52pm.

For many this means that when they get home from work it will now be dark and outdoor activities will be significantly curtailed as a result.

Arizona and Hawaii are the only states that do not observe Daylight Saving Time and remain on Standard Time year round.    The U.S. territories of Puerto Rico, American Samoa, Guam, Northern Mariana Islands, and the United States Virgin Islands also do not observe the event.

It won’t be all that long though before Daylight Saving Time returns.  On March 12, 2023 we will ‘spring forward.’

Daylight Saving Time Schedule

The mandated beginning and end of Daylight Saving Time has changed in the United States over the years.

The most recent schedule was set by the Energy Policy Act of 2005 and took effect in 2007.  We now ‘spring forward’ to begin Daylight Saving Time on the second Sunday in March and ‘fall back’ with the return to Standard Time on the first Sunday in November.

November 2022 preview: The transition to winter begins

Leave a comment

Thornton's November weather previewThe weather during the month of November in Denver metro area can offer just about anything.  While it is normally a quiet month, it can be prone to extremes.

November has historically been one of Denver’s snowiest months and major snowstorms are not entirely uncommon.  However conditions can also be quite dry.

Temperatures during the month continue to cool as we get closer to winter and by the end of the month the low temperatures routinely dip to 20 degrees or below.  At times it can in fact bring conditions more like what we see in January.

Get all the details on November’s weather and what we can expect in our complete preview here.

October 2022 weather recap: Mild temps, not much precipitation

Thornton, Colorado October 2022 Temperature Summary. (ThorntonWeather.com)

October 2022 goes into the books as one that saw Thornton experience above normal mercury readings and below normal precipitation. However, those were also a formula for a great number of pleasant, fall days.

Overall, Thornton’s average temperature for the month came in at an even 52.0 degrees. As measured at Denver International Airport, the Mile High City’s average temperature for the month was a good bit warmer coming in at 53.8 degrees.

Both readings were above Denver’s long term October average of 51.1 degrees and Thornton’s running 16-year average of 49.5 degrees.

Thornton saw a maximum temperature of 81.2 degrees occurring on the 20th and our coldest reading of 27.2 degrees occurred on the 29th. Denver maxed out at 79 degrees on the 20th as well and bottomed out 30 degrees on the 28th.

Precipitation was fleeting during the month and we were quite dry until the final week. Thornton totaled 0.43 inches in the bucket. Denver had a little bit more at 0.46 inches.

Both location’s totals were far below average. Denver’s long-term average for October is 0.99 inches while Thornton’s 16 year running average is at 1.04 inches.

While we did see some snowflakes mixed in with rain on the 27th of the month, it did not accumulate so we are still waiting for that first official snowfall.

October in Thornton can bring a wide variety of weather conditions, perfect for the photographer in all of us.

The month brings the changing of the colors at Colorado’s lower elevations and it is also is typically when we see our first freeze and first snow.

Couple those facts with our usual widely varying landscapes and wildlife and we have a month that is sure to bring in plenty of photo opportunities.

Winter weather – What does that weather warning mean?

Leave a comment
You have seen and heard the warnings but do you know what they really mean?
You have seen and heard the warnings but do you know what they really mean?

We all are familiar with the crawls on the TV screen or the announcements on the radio for winter weather advisories such as Winter Storm Watch, Blizzard Warning, Freeze Warning and more. But, how many of us really know what those mean? There is very specific criteria the National Weather Service follows in issuing these watches and warnings and there are important differences between all of them.

In this second in a series on Winter Weather Preparedness from the National Weather Service, ThorntonWeather.com helps you understand what all of these mean so you can be better prepared.

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOULDER CO
600 AM TUE OCT 18 2022

From the National Weather Service:

What does that warning mean?

When a warning is issued during the winter season, will you know what it means, and will you know how to respond? During this Colorado Winter Weather Preparedness Week, please become familiar with our list of potentially life-saving winter weather products.

OUTLOOKS

A Hazardous Weather Outlook is issued daily by the National Weather Service office in Boulder Colorado. The outlook provides information on potentially hazardous weather out to 7 days into the future. Also, the Weather Story, a graphic of expected hazardous weather, is posted daily on National Weather Service web sites.

WATCHES AND WARNINGS

A Winter Storm Watch is issued when hazardous winter storm conditions are possible within the next 3 to 4 days, but the timing, intensity, or occurrence may still be uncertain. In contrast, a Winter Storm Warning is issued for potentially life-threatening winter storm conditions, such as heavy snowfall or a combination of snowfall and blowing snow, which are likely to occur within the next 1 to 2 days. Impacts such as timing of winter weather on rush hour are also considered when issuing Watches and Warnings.

Winter Storm
Plains: 6″ in 12 hours, 8″ in 24 hrs
Mountains: 8″ in 12 hours, 12″ in 24 hours
And Impacts

Winter Weather Advisory
Plains: 3-6″ in 12 hours, 4-8″ in 24 hours
Mountains: 4-8″ in 12 hours, 6-12″ in 24 hours
And Impacts

Blizzard
Sustained wind or frequent gusts 35 mph or greater, AND
Considerable falling/blowing snow with visibility less than 1/4 mile, for at least 3 hours

ADVISORIES

Advisories for winter weather are issued for potentially hazardous conditions which are considered more of a nuisance than a life-threatening situation. However, if caution is not taken the advisory events could become life-threatening. Impacts such as timing of winter weather on rush hour are also considered when issuing Advisories.

Winter Weather Preparedness Week in Colorado will continue through Saturday.

Winter travel safety – Ensure you and your vehicle are ready

Are you and your vehicle ready for the winter weather ahead?
Are you and your vehicle ready for the winter weather ahead?

Before hitting the road, Coloradans need to ensure that they and their vehicles are prepared should inclement weather strike.

ThorntonWeather.com presents the first in a series from the National Weather Service (NWS) as part of Winter Weather Preparedness Week has declared by Colorado’s Governor.  Check back throughout the week for more winter preparedness stories.

Today’s message from the NWS highlights the importance of having a proper emergency kit in your vehicle and should the worst-case scenario occur where you get stuck, what you should do to survive.

Winter Travel Safety

Winter Weather Preparedness Week continues through Saturday October 23rd. Preparedness is a big part of this campaign. Before winter weather arrives in earnest, it is highly recommended that you prepare your car or truck for winter travel. This includes a winter survival kit and good snow tires.

Before winter weather arrives in earnest, it is highly recommended that you prepare your car or truck for winter travel.

A well-equipped vehicle has adequate tires, tire chains, tow rope, sand or cat litter for traction, shovel, tool kit, windshield scraper and brush, battery cables, first aid kit, flashlight, extra batteries, blankets and/or sleeping bags, extra clothing, candles, waterproof matches, jug of water, high calorie packaged food for quick energy, and an empty can to melt snow for drinking.

And during winter weather events, the best way to prevent treacherous winter travel is to avoid it. This can be done by staying informed about current weather and road conditions as well as the latest weather forecasts. Information on road conditions in Colorado is available on the web at www.cotrip.org or from the toll free number 1-877-315-7623. When calling from anywhere in Colorado, dialing 511 will also access the Colorado road reports. Additionally, a free smartphone application, CDOT Mobile, is available.

If you should become stranded during a winter storm, stay with your vehicle and do not panic. If accompanied by others, take turns sleeping. Run the motor every hour for about ten minutes to maintain warmth, but keep windows open a little to prevent the buildup of carbon monoxide. Make sure the exhaust pipe is not blocked. Keep the car visible with brightly colored cloths tied to the side view mirrors, door handles, or external antenna. At night, turn on the dome light when running the engine. Exercise periodically by vigorously moving arms, legs, toes and fingers.

In the mountains, avalanches become a possibility in the winter, especially below steep slopes. Avalanches occasionally come down across roads, with little or no warning. However, avalanche control work is performed on many avalanche prone roads in Colorado, making the roads safer to travel. Caution is advised when traveling along avalanche prone roads, especially during and shortly after a heavy snowstorm, as well as during periods of rapid snowmelt.

Very strong downslope winds occur at times mainly along the front range of Colorado. These Chinook and Bora winds can have gusts exceeding 100 mph. Persons planning travel in lightweight or high-profile vehicles should avoid travel during these strong wind events especially on north-south oriented roads.

Roads which appear to be clear in the wintertime may actually be coated with a thin layer of ice, commonly known as black ice. This nearly invisible ice layer can cause you to rapidly lose control of your vehicle. Black ice is most common during the nighttime hours. If you detect black ice you should reduce your speed.

Please follow these winter travel safety recommendations which could save your life.

Leaf peeping 2022: When and where to see the fall colors

Leave a comment

This time of year many folks start thinking about heading to the hills west of Denver in search of gold – fall foliage gold.

Where to go?  Below are five of ThorntonWeather.com’s favorite ones near Denver – plus a few further out and some bonus ideas.  After that, we will tell you where you can find a great website that provides regular updates on viewing conditions.

I-70 Corridor – If you’re looking for the easiest route, then this one is for you.  Simply head west on I-70 about 110 miles to Avon.  Between Vail and Avon, both sides of I-70 are lined beautifully with aspen.

Rocky Mountain National Park – One of the most popular summer destinations in the state is of course also a prime spot to view aspen in all their glory.  Once in the park head toward Bear Lake.  Glacier Gorge Junction provides a beautiful spot and you of course also get to enjoy all the splendor that Rocky Mountain National Park has to offer.  Extend your viewing by taking Trail Ridge Road all the way through to the west side of the park and the Grand Lake and Granby area.

Peak to Peak Highway – This little road trip can be a dual purpose trip – gambling and fall foliage viewing!  Take U.S. 6 through Clear Creek Canyon and then 119 through Blackhawk and Central City.  You can of course stop there if your wallet is fat enough and donate some money to the casinos.  From there continue on 119 toward Nederland.  Take highway 72 toward Ward and Allenspark.  There you will find more golden aspen than you can imagine, all with the Continental Divide nearby.

Poudre Valley Canyon –  Heading north on I-25 take Colorado 14 west and into Poudre Canyon and Roosevelt National Forest.  As you continue west you will come very near timberline as you come to Cameron Pass.  Amazing views abound!

Guanella Pass – This is a nice, relatively short drive from Denver.  From C470 take 85 through Bailey and Conifer, a nice drive unto itself.  When you come to the town of Grant, take the Guanella Pass Scenic and Historic Byway north to Georgetown.  The air is pretty thin along the way as you climb in excess of 11,500 views through the Pike and Arapahoe National Forests.

A couple other possibilities further from the Front Range:

Leadville / Aspen – From Denver take I-70 west to Copper Mountain and then Colorado 91 south over Freemont Pass to Leadville. Along the way there are plenty of viewing opportunities and Leadville is a nice little town to make a stop. From here you can take Highway 24 north back through Minturn and Vail. To extend the drive, take Highway 24 south to Colorado 82 and head toward Aspen. You can stop by the Maroon Bells in White River National Forest to view some of the most photographed mountains in Colorado.

Cottonwood Pass – From Denver take Highway 285 to Buena Vista. Head west on Main Street for seven miles then west on County Road 344 / Colorado 82. From there you start the climb up Cottonwood Pass with absolutely stunning views from the top. If you are up for it, you can continue down the west side of the pass into the Taylor Park area.

Honorable mentions worth considering:

  • Boreas Pass between Breckenridge and Como (County Road 10)
  • Kenosha Pass on Highway 285 between Bailey and Fairplay
  • Independence Pass (Colorado 82 between Aspen and Twin Lakes)
  • Colorado 103 from Evergreen to Echo Lake. Throw in a drive up Mount Evans for a bonus.

If you do head out, be sure to send us your pictures for inclusion in our monthly photo slideshows!

The month of September is typically one of the more pleasant months in Colorado.  Temperatures are usually comfortable and there is not normally a lot of weather drama.  That however does not mean there aren’t plenty of photo opportunities.

Wildlife is still quite active along the Front Range and flowers will hold on to their petals for at least the first part of the month.  Then of course there is the weather which you never know what to expect.  Thunderstorms, heavy rain, and even snow are a possibility.
