Update, 7:10pm:  Thornton is in full winter storm mode now.  Wet, heavy snowfall is being seen across the Front Range and it is far from over.  Many areas are reporting more than 5 inches of snowfall so far with some as high as nine inches.  Here at ThorntonWeather.com we are up to 5.2 inches and counting!

Thundersnow was reported at the outset of the storm and Parker Examiner Melody Jones reports it is continuing in her area.  It is a phenomena that many folks may not be familiar with but not all that unusal. 

The snow is falling at rates up to 3 inches per hour and has covered many roads, particularly those in the northern, western and eastern parts of the city.  Strong winds are driving the snow creating some drifting and limiting visibility. 

Forecast total snow amounts have increased to the 8 to 16 inch range for the Denver metropolitan area.  The foothills and Palmer Divide could see amounts approaching 2 feet. 

Heavy snowfall will continue through the night and hazardous conditions will persist.  All residents should avoid travel if at all possible.  If you must go out, be sure to carry emergency supplies with you.

At Denver International Airport is reporting significant delays with some arriving and departing flights however airlines currently are not reporting any widespread cancellations.  Air travelers should check with their airlines before going to DIA.

March 21 to March 27 - This week in Denver weather history
March 21 to March 27 - This week in Denver weather history

This may be the first full week of spring officially but as any longtime Colorado resident will tell you, spring-like weather is not a given this time of year.  As we look back at this week in Denver weather history, it is very clear that oftentimes Old Man Winter insists on hanging around for a bit longer.

18-21

In 1907…a warm spell resulted in 6 daily temperature records.  Record maximum temperatures of 82 degrees occurred on the 18th with 81 degrees on the 19th and 80 degrees on the 20th.  Record high minimum temperatures of 52 degrees occurred on the 19th and 20th with 54 degrees on the 21st.

19-21

In 1888…heavy snowfall totaled 8.6 inches over downtown Denver.  North winds were sustained to 27 mph on the 19th.

20-21

In 1878…warm days with high temperatures in the lower 70’s in the city…caused snow to melt on the palmer divide…which caused the waters in Cherry Creek to rise. The high…rapid running water damaged a home and eroded bridge footings and abutments.  Some bridges became unsafe for the passage of trains.
 
In 1904…southwest winds sustained to 48 mph with gusts to 60 mph warmed the temperature to a high of 68 degrees on the 20th.  The high was only 42 degrees on the 21st behind a cold front…which produced 1.3 inches of snow and northeast winds sustained to 27 mph overnight.
 
In 1923…post-frontal rain changed to heavy snow and totaled 8.2 inches over the city.  North winds were sustained to 27 mph with gusts to 29 mph on the 20th. This was the second major snow in a week.
 
In 1932…rain changed to heavy snow…which totaled 6.2 inches in downtown Denver.  North winds gusted to 22 mph on the 21st.
 
In 1948…heavy snowfall totaled 7.2 inches over downtown Denver.
 
In 1952…a major snow storm produced north wind gusts to 35 mph and dumped 16.9 inches of snowfall on Stapleton Airport.  The maximum snow depth on the ground was 13 inches due to melting.
 
In 2000…heavy snow fell in and near the foothills of Douglas and Jefferson counties.  Snowfall totals included:  9 inches near tiny town and 7 inches in Littleton.  Snowfall totaled only 1.8 inches at the site of the former Stapleton International Airport. North winds gusted to 34 mph at Denver International Airport on the 20th.

20-22

In 1944…heavy snow fell over metro Denver for a total of 36 hours.  The storm dumped 18.5 inches of snowfall over downtown Denver and 12.2 inches at Stapleton Airport. Fortunately…there were no strong winds with the storm. North winds to only 19 mph were recorded on the 21st.

21

In 1898…an apparent Canadian cold front produced strong winds and plunged temperatures from a high of 56 degrees to a low of 8 degrees late in the day.  North winds were sustained to 48 mph with gusts to 60 mph.
 
In 1908…light snowfall of 1.3 inches produced 0.10 inch of precipitation.  This…along with the 0.01 inch of precipitation on the 8th…resulted in the driest March on record with a total of 0.11 inch of precipitation.
 
In 1916…southwest winds were sustained to 46 mph with a gust to 48 mph.  The Chinook winds warmed the temperature to a high of 62 degrees.
 
In 1923…heavy snowfall totaled 8.0 inches in downtown Denver.
 
In 1953…northwest winds gusting to 57 mph briefly reduced visibility to 3/4 miles in blowing dust at Stapleton Airport.
 
In 1981…rain changed rapidly to snow…but totaled only 2.8 inches at Stapleton International Airport.  North winds gusting to 35 mph produced much blowing snow and reduced the visibility to a half mile at times.  Over the higher elevations of south metro Denver…4 to 6 inches of snow were measured.

Massive sandstorm turns China’s skies orange

China’s capital city was shrouded in a cloud or orange dust from a massive sandstorm that affected an area of 312,000 square miles. Residents and visitors to Beijing were forced to wear masks and glasses in an attempt to keep the dust at bay.

The nation’s weather forecasting service gave the air quality rating of ‘5’ – its worst possible rating. The service was urging residents to stay inside and avoid the unhealthy air.

Flights at Beijing’s international airport were delayed and visitors to Tiananmen Square and other popular locations were greeted with orange skies and obscured landmarks.

The massive storm which originated hundreds of miles away struck after midnight and was carried by winds reaching 60mph. The sandstorm, somewhat common in Beijing, is expected to last until Monday.

The storm’s reach will also extend Saturday to the Korean Peninsula where Seoul has issued dust advisories.

Experts have blamed the storms on deforestation and urbanization and have resulted in a marked increase in the number of sandstorms. One storm in 2006 deposited an estimated 300,000 tons of sand on Beijing.

The expansion of deserts in the nation are considered a grave risk as deserts now encompass one third of the land area. In recent years the government began a program to plant vegetation in an attempt to stop the growing deserts.

“The situation improved tremendously after that. Thanks to the mild climate and conservation efforts, Beijing had only one sandstorm last year,” Guo Hu, head of the Beijing Meteorological Station, told Xinhua on Saturday.

The eastern coast of Australia was on high alert as Tropical Cyclone Ului prepared to make landfall in Queensland. Packing winds approaching 75 mph (165 km/hr), the government has begun evacuations in advance of the powerful storm.

The Australian Bureau of Meteorology said that Ului had shown intensification over the past six hours and was warning it may strike land as a Category 3 storm packing winds to 105 mph (170 km/hr). Very destructive winds are forecast to begin affecting coastal areas late Saturday night and into Sunday morning.

Landfall is expected 625 miles north of Brisbane (1000km) between Bowen and Proserpine. As with any cyclone, the wind presents the most immediate danger. However heavy rain raises the risk of severe flooding as 8 to 12 inches is expected in the hardest hit areas.

In advance of the storm, Queensland issued a disaster declaration which clears the way for the government force the evacuation of those at risk. Currently the communities Townsville, Burdekin, Rockhampton, Whitsunday, Charters Towers, Mackay, and Isaac fall under the mandatory evacuation orders. Resort areas along the Great Barrier Reef have already been evacuated.

After one last shot from Old Man Winter, Thornton clears up

Thornton's weather forecast for Saturday, March 20, 2010
Sunny skies return to Thornton but temperatures remain cool.

Old Man Winter didn’t go down without a fight yesterday as he closed out Thornton’s last day of winter with a snowstorm. Today we look to start to bounce back on the first day of spring although temperatures will remain chilly.

Yesterday’s snowstorm dumped anywhere from 5 inches of snow on the eastern suburbs to well over a foot in the foothills (click here for the snowfall reports). Here at ThorntonWeather.com we recorded 5.2 inches.  March is Denver’s snowiest month with an average of 11.7 inches.  There may be more to come!

Roadways at lower elevations were mostly wet while in the high country, accidents forced the closure of some highways and chain laws were in effect. Get the latest Colorado & Denver road report here.

Today we will start out the weekend with lingering cold temperatures although we will see the return of some sun. Highs will be in the mid-30’s under mostly sunny skies as the storm system moves toward the east.

Sunday we continue to bounce back and will start to make short work of melting that fresh snow. Sunny skies will be overhead and high temperatures will be in the low to mid-50’s.

As we enter the next workweek, high pressure over the region continues the warming trend. Highs on Monday will be in the low to mid-60’s with mostly sunny skies.

Tuesday and into Wednesday another storm system has the potential to impact the Front Range although right now it isn’t looking to be as significant we the one yesterday. Tuesday’s temperatures should reach the mid-50’s but there will be a slight chance for rain showers. Overnight Tuesday and lasting into Wednesday there is a chance we could see some snow again.

The latter part of the week we will be a bit cooler than normal but still should have pretty nice days on tap for Thursday and Friday.

Winter storm arrives in Colorado; Heavy snow expected in Thornton

Weather warnings in effect as of Friday morning. (NWS)
Weather warnings in effect as of Friday morning. (NWS)

Update, 3:50pm: The snow keeps flying and the wind keeps blowing! Just about the time you think the snow is going to ease up Old Man Winter lets it fly yet again.

How cold and wet is it?  It is cold and wet enough to have frozen our anemometer (wind sensor).  So if you are wondering why we aren’t registering any wind, you know why!  🙂 

Snow continues to fall across much of the Front Range but it is heaviest in and near the foothills. A quick sampling of storm reports shows Thornton has recorded 4.5 inches, Arvada 6.0 inches and Boulder 9.4 inches. Click here for the complete listing of snowfall reports.

We are looking for the snow to gradually decrease from north to south. However, until it does this evening we will see periods of moderate to heavy snowfall. Total accumulations by the time the storm ends around midnight will range from a few inches out by DIA to 5 to 10 inches closer to town and 7 to 14 inches near the foothills.

The winds are picking up a bit this afternoon as well and that is creating blowing and drifting snow. Visibility may be limited on the roadways so please use caution. Most main roadways continue to be everything from wet to slushy but periods of heavy snow coupled with wind may cause conditions to deteriorate.

The Winter Storm Warning will continue to be in effect until midnight tonight.  Remember that a Winter Storm Warning means hazardous winter weather conditions are imminent or highly likely. Significant snow accumulations are occurring or expected. This will make travel very hazardous.

Out like a lion – Major snowstorm to close out winter

Tomorrow is the last official day of winter and Mother Nature is set to ensure the season goes out like a lion. A major winter storm will arrive over Colorado tonight and bring bitter cold and significant snowfall to Denver.

The storm system we have been watching all week has begun to move down from the Pacific Northwest and will be joined with a cold front from the north. A scattered mix of rain and snow will kick things off to the north this evening before moving south along the Front Range. That will then transition to all snow after midnight at which point snowfall rates will begin to pick up.

Tomorrow’s rush hours are sure to become a miserable mess for commuters and drivers should exercise caution. Heavy snow is likely during the early morning hours and it will last throughout the daytime.

Snow accumulations of 6 to 12 inches is possible with the highest amounts to the west. Most of the Denver metro area will be looking at 5 to 9 inches total accumulation between tonight and Saturday morning. See the forecast snow total map below.

85 years ago today – The nation’s deadliest tornado

News reports portray a dreary start to March 18, 1925 with heavy rain in the morning but nothing that would foretell the disaster that was to come. Before the day was over, parts of Missouri, Illinois and Indiana would be torn asunder and nearly 700 people would be dead.

Today marks the 85th anniversary of what we now call the Tri-State Tornado. The deadly twister was of the likes that had never been seen before – and hasn’t been seen since. That morning, the U.S. Weather Bureau’s forecast called for “rains and strong shifting winds.” Nothing that would indicate the horror that was to come.

The first reports of the tornado happened at 1:01pm near Ellington, Missouri. As it moved to the northeast the twister tore through the towns of Annapolis, Redford, Cornwall, Biehle, and Frohna. By the time it exited Missouri, 11 people were dead.

Illinois bore the brunt of the tornado as it continued on its deadly path. It crossed the Mississippi River and tore through Gorham, Johnston City, Murphysboro, De Soto, Hurst-Bush and a half dozen other Illinois towns. Entire towns were reduced to rubble, over a thousand people were injured and 613 people in the state were dead.

Far from over, the twister crossed into Indiana where the towns of Griffin, Owensville, and Princeton were hit. 71 people are thought to have died in the state.

The horror finally came to an end at 4:30pm, three and a half hours after it started. The tornado dissipated southwest of Petersburg, Indiana but not until after it had covered a path of at least 219 miles and left death and destruction the entire way. From southeastern Missouri, completely across southern Illinois and into southwestern Indiana, the tornado was the longest tracking twister ever recorded.

For more about the deadly tornado, maps of the path and images of the aftermath, read the complete story on the Natural Disasters Examiner.

Winter Storm Watch issued for Thornton for Friday as snowstorm approaches

Weather warning map
A Winter Storm Watch will be in effect for Thornton and the Front Range starting Thursday night. From 5 to 10 inches of snow is possible before Saturday morning. (NWS)

Friday is the last full day of winter and it appears the season if going to go out like a lion. A powerful system coming from the Pacific Northwest is going to bring a major change in the weather with significant snowfall for the entire Front Range.

We have been discussing the potential for this storm in our daily forecasts on Examiner.com all week. Denver will still enjoy one more day of unseasonable warm temperatures but as longtime residents know, the weather here can change on a dime and that looks to happen Thursday night.

The National Weather Service (NWS) has issued a Winter Storm Watch which goes into effect late Thursday night and lasts through Friday evening. Snow is expected to start after midnight and unfortunately for commuters it should be at its height by Friday morning at rush hour.

In their statement the NWS warns of “a significant change to harsh winter weather conditions” and that is what this system is going to bring. Temperatures are going to plummet nearly 40 degrees from the temperatures today and what is forecast for tomorrow. Highs on Friday will only be around 30 degrees.

In terms of snowfall, an inch or two will have fallen by Friday morning and then it will continue throughout the day and into the evening. Total snow accumulations for the Denver area could amount to 5 to 10 inches by Saturday morning. Higher amounts in the foothills and along the Palmer Divide are expected.
