January brings some amazing sunsets as seen in this image from Mary Lindow. Scroll down for a complete slideshow for the month. (Mary Lindow)
As one of our coldest months, January can be a good month to hibernate inside and avoid the outdoors. But, like any month in Colorado, photo opportunities abound as our monthly slideshow demonstrates.
Snow is not normally dominant in the month but when it does fall, it can create a beautiful blanket of white. Throw in the amazing sunrises and sunsets we receive in the middle of winter as well as wildlife and a host of other subjects and the imagery can be quite beautiful and stunning.

A significant winter storm is bearing down on Colorado and the state is blanketed with watches and warnings. The system has the potential to deliver our biggest snowfall of the 2015 / 2016 season thus far.
The National Weather Service has said 6 to 12 inches will be possible between Sunday night and Tuesday morning. Areas north of I-76 like Thornton will likely be at the lower end of the range but even at that it would be a healthy shot of snow.
Throughout the period we will of course be monitoring the system and posting regularly to our Facebook page and Twitter feed. You can follow along in real time below. We are also on Google+ here.
January 31 to February 6: This week in Denver weather history
Winds can be a blessing and a curse this time of year. Chinook winds can help warm what is otherwise a normally chilly season. They can also cause a great deal of damage as they pick up speed as they come roaring across the Front Range. While we have been lucky thus far this year and not had damaging wind events, looking back at this week in Denver weather history one can’t help but think that maybe it is just a matter of time before they strike.

Snowfall was only 1.6 inches at Stapleton International Airport where north winds gusted to 30 mph.
In 1995…the second morning in a row of strong winds raged in the foothills and adjacent lower elevations. Winds gusted between 70 and 85 mph in the foothills and 45 to 50 mph on the plains. A tree was blown onto high voltage power lines in a west Denver suburb. The fence that the wire landed on caught fire…but did no damage to the surrounding structures. A southwest Denver man was injured when a wind gust blew him and the front door he was holding off a porch. West winds gusted to 45 mph at Stapleton International Airport. The strongest winds occurred in Georgetown where a gust to 100 mph overturned a pick-up truck camper on I-70. The driver sustained only minor injuries.
In 2001…high winds developed briefly in the Front Range foothills. A spotter at Georgetown lake measured a peak wind gust to 90 mph.
In 2008…lightning struck a home in Englewood during an electrically charged snowstorm. A gas meter at the home was hit by lightning and burst into flames. The unusual thunderstorm produced a combination of snow and graupel. The graupel was up to one half inch in diameter. Total snow accumulations ranged from 1 to 4 inches across the southern Denver suburbs. Snowfall was only 0.6 inch at the former Stapleton International Airport.
2-3

The damage associated with the windstorm was extensive. Thirty 70-foot-tall power poles were damaged… Including several that supported high voltage lines transmitting electricity directly from generating plants. The combination of downed power poles…power lines…and trees resulted in outages for about 10 thousand residents. In Lafayette…power poles were sheared off for a mile and a quarter. The power outages primarily affected residents in Boulder…Broomfield…Lafayette…Louisville… And Fort Lupton. In addition to the outages…high winds ripped apart several roofs in Boulder…including the roof of the Boulder County jail. At Jefferson County Airport… Several planes were overturned and some hangars damaged or destroyed. Damage to the airport alone was estimated at 100 thousand dollars. In southern Jefferson County… Localized ground blizzards reduced visibilities in blowing snow to less than 20 feet along U.S. Highway 285…resulting in several accidents. In Pine Junction a downed tree damaged a nearby residence…when it crashed onto the roof. In Bailey…a downed tree crushed a vehicle parked in the resident’s driveway. Total damage estimates for the windstorm reached 3 million dollars…making it the fourth costliest on record at the time in Colorado. Other peak wind gusts include: 97 mph at Boulder…93 mph at the National Center for Atmospheric Research Mesa Lab in Boulder… 88 mph at Nederland…86 mph at Aspen Springs…and 83 mph at Blue Mountain near Coal Creek Canyon. West to northwest winds gusted as high as 46 mph at Denver International Airport.

January 17 to January 23: This week in Denver weather history
Chinook winds in January oftentimes bring welcome warmth to the Front Range. They can however be more of a curse than a blessing as at times they can reach hurricane strength and do extensive damage. Looking back at this week in Denver weather history, we see many such occurrences.
From the National Weather Service:
14-21
In 1930…a protracted cold spell occurred when low temperatures plunged below zero on 8 consecutive days. The coldest low temperatures of 20 degrees below zero on the 17th and 19 degrees below zero on the 16th were record minimums for the dates. High temperatures during the period ranged from 18 on the 18th to zero on the 20th. Two degrees on the 15th was a record low maximum temperature for the date.
15-23
In 1962…a protracted cold spell kept metro Denver in the deep freeze for more than a week. From the 15th thru the 23rd…low temperatures were zero or below for 9 consecutive days…but a daily record low was set only on the 22nd when the temperature dipped to 14 degrees below zero. A record low maximum for the date was also set on the 22nd when the temperature climbed to only 11 degrees. The coldest high temperature was 3 degrees above zero on the 21st…which did not break the record. The protracted cold was broken for only a few hours on the afternoon of the 20th when Chinook winds warmed the temperature to a high of 38 degrees before another surge of cold arctic air plunged temperatures back into the deep freeze that evening. The severe cold caused much damage to water systems. A woman was frozen to death at Morrison. There were other deaths attributable to the weather…including traffic deaths and heart attacks from overexertion.
16-17
In 1886…a brief cold spell resulted in two temperature records. High temperatures of zero degrees on the 16th and 2 degrees below zero on the 17th were both record low maximums for the dates. Low temperatures of 8 degrees below zero on the 16th and 16 degrees below zero on the 17th were not records.
In 1930…temperatures plunging well below zero resulted in two records. Low temperatures of 19 degrees below zero on the 16th and 20 degrees below zero on the 17th were record low temperatures for the dates. High temperatures were 4 degrees on the 16th and 15 degrees on the 17th. Light snowfall totaled 4.0 inches. North winds were sustained to 18 mph on the 16th.
In 1964…high winds struck the eastern foothills. Gale velocity winds were recorded in Boulder with gusts to 83 mph measured at Rocky Flats. Several airplanes were damaged at the Jefferson County Airport in Broomfield. Roofs…walls…and parts of buildings were blown away at various locations. Power poles and trees were blown over.

In 1943…light snowfall totaled 3.2 inches over the 3 days. This was the only measurable snow of the month. North winds were sustained to 20 mph on the 16th.
In 2011…very strong winds associated with an upper level jetstream over Colorado produced blizzard conditions in the mountains above timberline. Peak wind gusts included: 99 mph atop Loveland pass…94 mph… 2 miles southwest of Mary Jane…80 mph atop Berthoud Pass and 79 mph atop Niwot Ridge. Storm totals in the ski areas west of Denver ranged from 8 to 14 inches.

In 1872…light snow fell during the morning and continued into the afternoon until 3:30 pm. The sky commenced to clear a little before 2:00 pm…but snow fell thickly for at least half an hour even though the sky was perfectly clear overhead. Melted snow totaled 0.33 inches.
In 1888…northwest winds were sustained to 46 mph in the city.
In 1905…intermittent rain…unusual in January…occurred during the day. The rain changed to snow during the late evening…but ended before midnight. Snowfall was 2.0 inches. Precipitation totaled 0.62 inch. The temperature ranged from a high of 44 degrees to a low of 32 degrees.
In 1950…wind gusts to 62 mph caused some blowing dust at Stapleton Airport.
In 1982…one of the worst wind storms in many years hit the Front Range foothills. The strongest winds occurred in Boulder where at 2:30 am a wind gust to 147 mph was recorded at the National Center for Atmospheric Research…on the mesa in southwest Boulder. At this location 20 wind gusts over 120 mph were clocked between 1:00 am and 9:00 am. An estimated 40 percent of all buildings in Boulder received at least minor wind damage. About 50 homes were damaged enough to be uninhabitable. At least 15 homes in the Table Mesa area of Boulder lost roofs. Twenty small airplanes were destroyed at the Boulder airport. Utility poles were snapped in two…and about one-seventh of the buildings in the area were without power. Insured damage totaled 20 million dollars making the wind storm the most costly on record in Colorado at the time.
In 1989…high winds were recorded along the eastern foothills with gusts to 90 mph recorded at Rollinsville. North of Denver on I-25…the wind injured two men when their tractor trailer was blown off the road and rolled. West winds gusted to 48 mph at Stapleton International Airport.
In 1990…an intense but localized snow storm caught many people by surprise when it dumped 3 to 6 inches of snow during a 3-hour period across portions of Boulder County. The storm swath approximately 20 to 30 miles wide stretched northeast from Boulder to just east of Longmont. Only light snow fell over the remainder of metro Denver with 0.2 inch of snowfall measured at Stapleton International Airport where northeast winds gusted to 30 mph.
In 1998…strong winds in the foothills spread over the plains mainly north of metro Denver. Winds gusted to 75 mph at Golden Gate Canyon. West winds gusted to 34 mph at Denver International Airport.
17-18

In 2012…damaging winds developed in and near the Front Range. In Boulder…the high winds knocked down several trees… Power poles and electrical lines. Some of the fallen trees damaged homes and automobiles. A semi-trailer was blown on its side along State Highway 93 near Marshall. Peak wind gusts included: 104 mph in south Boulder; 98 mph…3 miles southwest of Pinecliffe; 95 mph…2 miles northwest of Rocky Flats; 92 mph…at State Highway 93 near Marshall; 87 mph at Berthoud Pass and in Boulder Canyon; 80 mph…5 miles west- northwest of Boulder; 83 mph at NCAR Mesa Lab; 78 mph…8 miles northeast of Four Corners; 79 mph at the National Wind Technology Center; 76 mph at Wondervu; 75 mph atop Loveland Pass and the NCAR foothills lab in Boulder; 74 mph at Blue Mountain…Boulder Municipal Airport… 1 mile northwest of Lyons; 73 mph…4 miles east-northeast of Nederland; 72 mph at the junction of State Highways 72 and 93; 62 mph in Superior; and 61 mph at Erie Municipal Airport.

Remarkably, Alex has undergone the transformation into a hurricane. It’s the first hurricane to form in the month of January since 1938, and the first hurricane to be present in this month since Alice of 1955. (Alice formed in late December 1954 and carried over into January 1955.) Alex’s maximum sustained winds are near 85 mph (140 km/h) with higher gusts – a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength through Friday is forecast.
At 1100 a.m. AST (1500 UTC), the center of Hurricane Alex was located about 490 miles south of Faial Island in the Central Azores, moving toward the north-northeast near 20 mph (31 km/h). A turn toward the north with an increase in forward speed is expected over the next day or two. On the forecast track, the center of Alex will move near or over portions of the Azores Friday morning.
The Azores Meteorological Service has issued a Hurricane Warning for the islands of Faial, Pico, Sao Jorge, Graciosa, and Terceira in the central Azores, and a Tropical Storm Warning for the islands of Sao Miguel and Santa Maria in the eastern Azores.
Tropical-storm-force winds are expected to begin over portions of the Azores tonight. Hurricane conditions are expected to spread over the central Azores by early Friday. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater.
Alex is expected to produce total rain accumulations of 3 to 5 inches over the Azores through Friday, with possible isolated maximum amounts of 7 inches. These rains could produce life-threatening flash floods and mudslides. A dangerous storm surge is expected to produce significant coastal flooding near and to the east of the center of Alex. Near the coast, the surge will be accompanied by large and destructive waves.

If you were looking for a location which defined the term ‘the middle of nowhere’, Johnston Atoll would have a strong claim. This uninhabited island lies 1,390 kilometres southwest of the Hawaiian Islands, themselves lying in a remote part of the Pacific. Johnston Atoll is mentioned here because it is the closest island to what has… Continue reading Hurricane Pali sets Pacific record→
If a monster asteroid is headed towards Earth, perhaps the planet is a little more prepared. NASA announced Friday that the Planetary Defense Coordination Office is now open for business, tasked with a succinct mission: to track and characterizing all asteroids and comets that veer too close to Earth – and figure out a response to… Continue reading Relieved?
