After a pleasant days-long stretch of warm weather often eclipsing the 70-degree mark, northern Colorado and metro Denver will see quite a change in conditions starting Friday night.
Instead of breaking records for heat, temperatures will drop substantially and snow will begin falling in the far northern mountains tonight, spreading southward into the Interstate 70 mountain corridor and Summit County by late Saturday afternoon.
By late Saturday night, the National Weather Service predicts areas of snow to develop along the Interstate 25 corridor and along the adjoining eastern plains, with travel impacts continuing into Sunday morning. Some of those areas of snow could start out as rain earlier Saturday evening before turning to snow.
Just how severe those travel impacts will be in metro Denver are still in question.
“There is considerable uncertainty with regard to the amount of snow, since we anticipate bands of snow,” according to a weather service bulletin issued Friday afternoon for the metro area. “Thus, some areas may receive very little or no snow, while others get a few inches.”
Higher amounts of snow are assured for some of Colorado’s northern mountains, with the National Weather Service forecasting around 10 inches for Winter Park, 5 inches for Breckenridge and half a foot of the white stuff for Keystone. The predicted weekend snowfall for some of Colorado’s snow-starved ski resorts will come as welcome news to an industry that has seen a decidedly dry start to the season.
Meteorologists are calling for a low of 20 degrees Saturday night, a low of 14 degrees Sunday night and a low of 21 degrees Monday night in the metro area. But by Tuesday and towards New Year’s Day, temperatures will top out in the 40s and 50s with little precipitation expected.
A slowly growing, nearly contained wildfire burning on Colorado’s Western Slope is now the fourth-largest on state record, according to fire officials.
As of Monday night, the 90% contained Lee fire had scorched 138,844 acres between Meeker and Rifle. It grew by 1,086 acres on Monday, after multiple days with minimal to no growth.
The new acres consumed by the Lee fire bumped the wildfire from fifth-largest to fourth-largest in Colorado history, passing the 137,760-acre Hayman fire that sparked in 2002, according to the Colorado Division of Fire Prevention and Control.
The Lee fire is now less than 200 acres away from becoming the third-largest wildfire on state record. Currently, that ranking belongs to the 2020 Pine Gulch fire that burned 139,007 acres.
Rain showers and thunderstorms are forecast across the Western Slope again on Tuesday, bringing much-needed moisture to the state, fire officials said. Previous hot, dry and windy conditions fueled rapid fire growth in multiple counties across western Colorado, charring thousands of acres outside of the Lee fire.

Lee and Elk fires, near Meeker
The largest wildfire burning in Colorado — now the fourth-largest ever recorded in the state — consumed more than 1,000 new acres after a week of slow growth and increased containment, fire officials said.
As of Monday night, the 138,844-acre Lee fire burning between Meeker and Rifle was 90% contained, fire officials said.
All mandatory evacuation orders were lifted Saturday, and areas on pre-evacuation status were downgraded to monitoring status on Monday.
No new evacuation orders were issued overnight Monday, despite the new fire growth. An updated evacuation map for Rio Blanco and Garfield counties is available online.
The Lee fire and nearby Elk fire, which consumed more than 14,500 acres before reaching full containment last week, have together destroyed at least five homes and 14 outbuildings, fire officials said.
Extreme drought, high temperatures and strong winds fueled rapid growth on both fires, which were sparked by lightning west and east of Meeker on Aug. 2.
Thunderstorms are most likely near Meeker and Rifle between 9 a.m. and midnight on Tuesday, according to the National Weather Service. Rain showers, which are also expected in that period, could continue through 3 a.m. Wednesday before a brief reprieve.
Rainy weather is expected to continue on Wednesday and Thursday, forecasters said.
While the rain is helpful, afternoon thunderstorms also increase the risk of gusty winds, frequent lightning and flash flooding along burn scars, fire officials said.
Road closures tied to the smaller Crosho fire near Yampa were lifted Monday afternoon. That fire has burned 2,073 acres and is 81% contained.

Derby fire, in Eagle County
A wildfire burning on the edge of Eagle and Garfield counties has scorched more than 5,300 acres, fire officials.
The Derby fire is burning on 5,346 acres with no containment, up roughly 100 acres from Sunday and 1,200 acres from Saturday, fire officials said Monday. No size update was available Tuesday morning.
“We have totally changed the pattern from hot and dry,” said meteorologist Ryan Fliehman in a Monday evening briefing. “I’m afraid we might get too much rain. We are still having chances of precipitation six days out.”
Rain has forced some fire crews to pull back, and crews need to take extra care to avoid damaging dirt roads, which have turned muddy, Operations Chief Ben Patton said.
No containment has been reported on the fire, but officials hope to start solidifying the first bits of containment in the coming days.
The Derby fire was discovered on “remote, rugged terrain” in the White River National Forest, about 15 miles from Dotsero in Eagle County, on Aug. 17, according to the U.S. Forest Service.
It differs from the others burning in Colorado in that it started at higher elevations and has tried to push downhill at night.
Mandatory evacuations and pre-evacuations are in place for the northwest corner of Eagle County, including the town of Gypsum, and an eastern section of Garfield County.
Evacuations were lifted for Sweetwater Valley and Sheep Creek at 10 a.m. Monday, allowing limited access for residents to return home, according to fire officials. Those who need to access Sweetwater Valley and Colorado River Road are being asked to limit their driving to between 10 a.m. and 4 p.m. to avoid disrupting emergency operations.
At least one building has been destroyed by the wildfire, but it’s unclear what type of building it was.
Parts of White River National Forest remain closed in Eagle and Garfield counties, including southwest of Sweetwater Lake to the west rim of Deep Creek Canyon, according to the U.S. Forest Service. Some BLM lands are also closed, including north and west of Gypsum, north of Coffee Pot Road, west of the Colorado River, east of the White River National Forest boundary and south of Derby Creek.
Colorado’s fifth-largest wildfire on record is 90% contained as rain showers and thunderstorms continue across the Western Slope, fire officials said.
As of Monday morning, the Lee fire had consumed 137,758 acres, equal to roughly 215 square miles. The burn area is just two acres short of Colorado’s fourth-largest wildfire on record — the 137,760-acre Hayman fire that sparked in 2002.
Other wildfires burning on Colorado’s Western Slope have scorched thousands of additional acres. Fire officials across the state have said hot, dry and windy conditions fueled the flames’ rapid growth.
Storms over the next several days will bring much-needed rain to the drought-stricken Western Slope, according to the National Weather Service. But those storms also increase the risk of lightning and strong winds — weather that can start fires and fan the flames of those already burning.

Lee and Elk fires, near Meeker
Growth on the largest wildfire burning in Colorado — the fifth-largest ever recorded in the state — has slowed over the past week as firefighters increase containment around the flames.
As of Monday morning, the 137,758-acre Lee fire burning between Meeker and Rifle was 90% contained, fire officials said.
“Minimal work” remains to fully contain the wildfire, Incident Commander Brent Olson said in a Sunday afternoon briefing.
All mandatory evacuation orders were lifted Saturday, but multiple areas around the fire remain on pre-evacuation status. An updated evacuation map for Rio Blanco and Garfield counties is available online.
The Lee fire and nearby Elk fire, which consumed more than 14,500 acres before reaching full containment last week, have together destroyed at least five homes and 14 outbuildings, fire officials said.
Extreme drought, high temperatures and strong winds fueled rapid growth on both fires, which were sparked by lightning west and east of Meeker on Aug. 2.
Rain showers and cooler temperatures helped mitigate the flames last week, which allowed firefighters to steadily increase containment. More showers and thunderstorms are expected in the days ahead as Colorado braces for a monsoonal weather system.
Rain showers and thunderstorms are most likely near Meeker and Rifle between 10 a.m. and 8 p.m. Monday, according to the National Weather Service. Chances of precipitation range from 30% to 50%, forecasters said.
Chances of rain greatly increase later this week in both areas, jumping to 90% Tuesday afternoon and remaining there until 11 a.m. Wednesday, according to hourly forecasts from the weather service.
While the rain is helpful, afternoon thunderstorms also increase the risk of gusty winds, frequent lightning and flash flooding along burn scars, fire officials said.
Heavy rains caused flash flooding in the Lee fire burn area on Sunday afternoon. The water caused a debris flow, which was blocking Piceance Creek Road, officials said in a Sunday afternoon update. It’s unclear if rain caused flooding in the Elk fire burn scar.

Derby fire, in Eagle County
A wildfire burning on the edge of Eagle and Garfield counties has scorched more than 5,300 acres, fire officials said Monday.
The Derby fire is burning on 5,346 acres with no containment, up roughly 100 acres from Sunday and 1,200 acres from Saturday, fire officials said.
Thunderstorm activity and gusty winds have driven the fire south in recent days, meteorologist Ryan Fliehman said in a Sunday afternoon briefing.
Rain showers and thunderstorms started Sunday afternoon and are expected to continue through Wednesday as a “strong monsoonal push of moisture” hits the Western Slope, Fliehman said.
The storms will help dampen the quickly spreading wildfire but may create other problems on the newly charred landscape, like flash flooding, fire officials said.
The Derby fire was discovered on “remote, rugged terrain” in the White River National Forest, about 15 miles from Dotsero in Eagle County, on Aug. 17, according to the U.S. Forest Service.
Mandatory evacuations and pre-evacuations are in place for the northwest corner of Eagle County, including the town of Gypsum, and an eastern section of Garfield County.
Evacuations will be lifted for Sweetwater Valley and Sheep Creek at 10 a.m. Monday, allowing limited access for residents to return home, according to fire officials. Residents will be required to present proof of address at checkpoints along Colorado River Road.
That area will remain on pre-evacuation status and people may be required to re-evacuate if conditions change, fire officials said. Livestock will not be allowed to return yet. The wildfire’s activity remains unpredictable.
“This is not a full repopulation, as the risks are still very high and residents should remain prepared to vacate at any time,” Eagle County Sheriff James Van Beek said in a statement on social media.
Travel within the restricted area must remain extremely limited to protect both residents and fire crews, sheriff’s officials said. The best window for essential travel is between 10 a.m. and 4 p.m., when conditions are safest and least disruptive to emergency operations.
The Eagle County Sheriff’s Office is working on a plan to allow some evacuated residents to access their homes, specifically “those who own property or depend on it for their livelihood,” sheriff’s officials said Sunday. Exact details of that plan were not available, and the evacuation orders remain in place.
At least one building has been destroyed by the wildfire, but it’s unclear what type of building it was.
The U.S. Forest Service also expanded closures in the White River National Forest in Eagle and Garfield counties, including southwest of Sweetwater Lake to the west rim of Deep Creek Canyon. Some BLM lands are also closed, including north and west of Gypsum, north of Coffee Pot Road, west of the Colorado River, east of the White River National Forest boundary and south of Derby Creek.

Stoner Mesa fire, near Dolores
The Stoner Mesa fire is burning on 10,233 acres in a remote section of the San Juan National Forest, fire officials said Sunday.
Multiple areas around the fire — including Mavreeso, Gobble Creek, Fish Creek, Johnny Bull Creek, Dunton, Lizard Head, Horse Creek, Rico and Sulfer Creek — remain on “monitor” status, the step before pre-evacuation orders, according to the wildfire’s evacuation map.
All pre-evacuation orders were lifted Saturday, but sections of the San Juan National Forest remain closed for the wildfire.
As of Sunday, the lightning-sparked Stoner Mesa fire was 41% contained.

Air-quality impacts
Air quality alerts for wildfire smoke near the Derby and Stoner Mesa fires were issued Sunday morning by the Colorado Department of Public Health and Environment.
The warnings, which include southeastern Dolores County, northeastern Montezuma County, western Eagle County and eastern Garfield County, will remain active through at least 9 a.m. Monday.
Smoke will be heaviest in the areas near the fires, especially during the overnight and early morning hours, state health officials said. Incoming storm systems should help improve air quality near the fires.
Smoky conditions are most hazardous for young children, older adults and people with heart disease or respiratory illnesses, according to state health officials.
All residents should limit outdoor activity when heavy smoke is present. If visibility drops to 5 miles or less, the smoke has reached unhealthy levels.
The Washington tribes that agreed to provide wolves to Colorado’s reintroduction program have rescinded their offer, forcing state wildlife officials to seek a different source — a search that has proved difficult in the past.
The Confederated Tribes of the Colville Reservation said they would no longer provide the wolves after speaking with the Southern Ute Indian Tribe, which has reservation land in Colorado. The Washington tribes — which had been expected to be a major source for the next round of the reintroduction effort — withdrew their agreement in a June 6 letter to Colorado Parks and Wildlife.
“It has come to our attention that necessary and meaningful consultation was not completed with the potentially impacted tribes,” wrote Jarred-Michael Erickson, chairman of the Colville business council, in the letter. “Out of respect for the sovereignty, cultures and memberships of Indian Tribes in Colorado and neighboring states, who may be impacted by this project, the Colville Tribes cannot assist with this project at this time.”
Colorado voters in 2020 narrowly decided to reintroduce gray wolves and mandated that state wildlife officials do so by Dec. 31, 2023.
The plan detailing how CPW will execute the reintroduction effort states that the agency should release a total of 30 to 50 wolves within the next few years, a target it plans to reach by relocating 10 to 15 wolves every winter.
The controversial vote has caused deep frustration in Colorado’s ranching communities, where people say the wolves will negatively impact their businesses and ways of life. Support for the reintroduction primarily came from urban Front Range communities, while the rural areas where wolves would live opposed the measure.
The Southern Ute Indian Tribe has concerns about the wolves potential impact on livestock, deer and elk herds and their use of the Brunot Area hunting rights reserved for tribal members, tribal leadership said Thursday in a statement. Tribal leaders said they would continue to work with Colorado Parks and Wildlife “to establish a framework for working together that enables the state to implement its reintroduction program while simultaneously recognizing the sovereign authority of the Tribe on tribal lands and the interest shared by the Tribe and the State in the Brunot Area.”
So far, CPW’s monthly maps showing where the wolves have roamed have indicated activity in the central and northern mountains, far from the Southern Utes’ southwestern Colorado reservation. But plans call for the next round of releases to occur farther south.
Colorado wildlife officials struggled last year to find a state or tribe willing to provide wolves for reintroduction here. The three states identified as ideal for sourcing wolves — Idaho, Montana and Wyoming — all rejected Colorado’s request for wolves.
CPW spokesman Joey Livingston on Thursday declined to discuss source negotiations and said the agency would issue a statement when it finds a source.
“We continue speaking with other potential sources of wolves,” he wrote in an email, “and will take great care in implementing the plan to create a self-sustaining wolf population while minimizing impacts on our landowners, rural communities, agricultural industries and partners.”
In October, Oregon agreed to provide up to 10 wolves over the coming winter. Ten wolves captured in Oregon were released in Colorado in December.
Colorado wildlife officials have also talked with Washington state officials about potentially capturing wolves there. While Washington officials previously said they could not provide wolves for the first release, they indicated they were open to further conversations.
For the first time since they were reintroduced to the state in December, Colorado’s gray wolves have moved out of central Grand County, state wildlife officials said in their July report.
In July, the 11 wolves and one pup stayed relatively in the same watershed areas as they did in May and June, traveling between Routt, Jackson, Larimer, Grand, Eagle and Summit counties, according to a new location map released Tuesday by Colorado Parks and Wildlife.
CPW releases a map each month showing which watersheds the state’s collared wolves have traveled in, wildlife officials said. A wolf may or may not remain there now, and it may not have traversed every part of that watershed.

The updated map shows wolf activity from June 25 through July 23 in watersheds from the Wyoming border to Interstate 70 and from west of Craig in Moffat County to west of Fort Collins in Larimer County.
While the monthly maps from December to June have shown wolves using watersheds across Grand County to the border of Boulder County, the July map showcases a lack of data in the area, indicating that wolves didn’t visit the area at all during July.
The collars record a GPS position every four hours and send the data to state biologists once four locations are recorded, CPW officials said. State officials do not share specific locations to protect the wolves and may “buffer” maps to protect wolves during certain times of year, such as mating season.
Although July’s map highlighted watershed areas south of Interstate 70, CPW officials said no wolves had passed the major highway and the population was exploring land to the north.
Since then, CPW officials said two of the wolves have mated together and given birth to at least one pup, and a pair of Wyoming-based wolves naturally migrated into the state and joined the Colorado pack.
Two of the ten collars placed on wolves in December stopped working, but those two wolves are still alive and traveling with other wolves with functioning collars, state officials said in April. There are no current plans to recollar the wolves or place collars on any of the pups.
The map’s accuracy will drop over time as wolves move into Colorado from other states, collars stop working and more wolves mate together and give birth to pups, state wildlife officials said. The goal is to keep at least two collared wolves in each pack.
Sally Johnston, mother of Denver Mayor Mike Johnston and co-owner of the Christiania Lodge at Vail, passed away May 17, with the mayor joining her for a final goodbye.
The city leader announced his mom’s passing in a LinkedIn post on Saturday.
“Yesterday we said the final good bye to my mom,” Johnston wrote. He depicted her as selfless, joyful and “a tireless force for goodness.”
Sally Johnston grew up in Port Leyden, N.Y., alongside three sisters. Her father worked as a school principal, while her mother was an arts and music teacher, according to a 2010 article in the Vail Daily.
She followed in their footsteps — teaching music in Boston in the 1960s, her son Mike recalled in his social media post. There, she spearheaded a Head Start program, the Vail Daily reports.
She married her husband, Paul Ross Johnston, in 1970 — the former mayor of Vail, who passed away in 2015. The pair bought a boutique hotel in Vail in 1976.
With her experience in education and psychology, Sally Johnston served as a board member at Third Way Center, a nonprofit that helps youths resolve trauma. She also had a spot on the Vail Mountain School Board and was involved with the Vail Religious Foundation.
“She loved people for their beauty and their brokenness alike, which always had the power to make each of us feel unafraid, unashamed, perfect again — the way we were once before the world taught us to doubt,” Johnston wrote. “She changed my world, and she convinced me with a ferocity I will never surrender that we can all change the world, because I watched her do it every day.”
