Where's Denver? This webcam view from the Colorado Department of Public Health and Environment shows Denver obscured in the snowfall at 1:00pm Thursday.

If you can, get out of work early today as the roads are sure to be a mess during rush hour.  Snow has been falling across the Front Range all day and snow totals for the metro area are in the 2 to 4 inch range.  Probably just as notable is the bitter cold we are seeing – at 1:00pm DIA was showing 17 degrees and a wind chill of only 2 degrees.  Denver’s high temperature today will most likely be 22 degrees but that was reached at 1:00am!  The wind will continue to keep the wind chills down around zero so bundle up if you head out.

The snow will continue through 11:00pm although accumulations will be pretty light.  The north, west and southern suburbs could see up to 6 inches of snow while the central metro area will end up with around 2 to 4 inches.  Areas of Larimer and Weld Counties including Fort Collins and Greeley will see between 5 to 10 inches of snow. 

A Winter Weather Advisory is in effect for the I-25 corridor north of Longmont as well as most of the central and northern mountains areas.  The extreme eastern portions of the state are under an advisory as well.  In the mountains, eastbound I-70 has chain restrictions in place at the Eisenhower Tunnel, Loveland Pass and at Vail.

Tonight we will dip into the single digits but Friday brings us back into the 40’s and the weekend looks great.

The snow arrived overnight and as of 5:00am ThorntonWeather.com had measured 1.3” and it was still coming down pretty good.  Due to the extreme cold – 17 degrees and a windchill of 5 degrees as of this writing – the roads are quite slick.  This morning we found residential streets to be the worst of course but main arterials like 120th Ave were not in too good of shape either.  Please allow plenty of time to get the kids to school and yourselves to work, allow plenty of distance between you and other cars and just take your time. 

A surge of cold air from the north is expected to intensify the snowfall in the coming hours and a bit of upslope will keep the flakes falling for most of the day.  Accumulations though won’t be all that great – look for 2 to 4 inches overall.  Snow will taper off this evening from the north to the south and completely end in the metro area around midnight.

Friday and this weekend are shaping up great but that could be short lived.  We are watching a cold front coming from Montana that could bring more cold and snow toward the first part of next week.

With only two days to go in the month, things were pretty bleak and we were dangerously close to joining the “top 10” for the least snowiest Novembers in Denver.  That changed in pretty short order last night.  Forecasters were expecting about an inch of snow but the local storm reports indicate most areas exceeded that handily. 

Here in Thornton we started with a touch of rain in the evening which changed to snow as time went on and the temperature dropped.  In the end we recorded 4.1″ of the white stuff, most of which fell between 10:00pm and midnight. 

The National Weather Service in Denver is officially showing 2.4″ of snow at the old Stapleton International Airport site.  At Denver International Airport they recorded 1.6″. 

Some of the other snow reports that have come in (Updated @ 11:15am):

  • Arvada – 2.4″
  • Brighton – 1.5″
  • Conifer – 2.5″
  • Denver (north) – 1.5″
  • Denver (Stapleton) – 3.2″
  • Denver (DIA) – 1.7″
  • Elizabeth – 3.2″
  • Evergreen – 3.2″
  • Erie – 4.5″
  • Highlands Ranch – 3.0″
  • Henderson – 3.0″
  • Highlands Ranch – 4.5″
  • Lakewood – 3.8″
  • Lone Tree – 3.2″
  • Parker – 1.8″
  • Thornton – 4.1″
  • Westminster – 2.2″

December weather preview - what can we expect in Denver?
December weather preview - what can we expect in Denver?

December brings with it the official start to winter and at the same time we find ourselves hoping we get moisture in the near future. As of this writing, the mountain snowpack in all basins are well below normal, with some as low as 27% of normal. Here in town our our annual snowfall is well below normal as well. In Colorado the snow season starts on July 1st and between that date and November 30th, Denver averages 16.9 inches of snow. Thus far, ThorntonWeather.com has measured a meager 0.2 inch and the official total for Denver taken at the site of the old Stapleton International Aiport stands at 0.8 inch!

So what can we expect in the coming month?  Click here to read our December 2008 climate and weather preview to find out!

City of Thornton launches Thornton Connected

1 Comment

For those that may not have noticed it in the most recent issue of Inside Thornton, the city has launched a new service called Thornton Connected.  This new website and system allows area residents access to all sorts of new information from the city.  First is a Frequently Asked Questions (FAQ) section of the website that covers the entire breadth of city services.  That same information is also available by phone.  Second is an email subscription service that allows area residents to receive periodic emails from the city on a range of topics from just about every city department. 

We have subscribed to many of the email newsletters and have them to be very informative.  The city is also doing a great job of ensuring the number of messages isn’t overwhelming and is only sending out the important stuff.  We commend the City of Thornton on this new service for residents! 

At the current time the system is only for non-emergency messages.  We do wish and hope the city will consider expanding the system to include emergency messages such as tornado warnings, Amber Alerts and other emergency alerts.  The city does not have an emergency siren system or any other way to disseminate emergency information to residents and we believe this would be a valuable and potentially life saving service.  A number of municipalities across the country and in Colorado have implemented such systems.  We are going to talk to the city about this and will update you when we learn more about their plans. 

You can learn more about Thornton Connected on the city’s website or by going directly to http://connected.cityofthornton.net.  As we mentioned, the winter issue of Inside Thornton also has information on the service.  You can download the issue by clicking here – page 10 and 11 have the Thornton Connected information.

ThorntonWeather.com sneak peek – Storm Chasers episode 3 preview

2 Comments
Test
The three stars from Storm Chasers: Sean Casey - TIV Chief and Champion Storm Chaser, Dr. Josh Wurman - Research Meteorologist, and Reed Timmer - TVN Lead Storm Chaser, Meteorologist

A little birdie with the Discovery Channel popped in with a surprise for me and for ThorntonWeather.com readers – a sneak peek at this coming Sunday’s episode of Discovery Channel’s Storm Chasers! 

For those that haven’t seen the show, it is must see TV, even if you aren’t much into weather.  The show chronicles a team of storm chasers as they crisscross the Great Plains hunting tornadoes.  They have an array of high tech gagetry at hand to help them in their chase to further our understanding of the storms including the TIV – Tornado Intercept Vehicle.  The TIV’s primary function?  To drive into a tornado! 

The third episode’s summary says:

Storm Chasers
Mutiny on the Plains
Sunday, Nov 02 at 10:00 pm E/P on Discovery Channel
Tensions mount between Sean and Josh, as Reed offers to chase with the TIV. Reed chases a risky nighttime tornado into the hills of Arkansas, while Sean and Josh return to Greensburg, Kansas one year after a twister nearly wiped the town off the map.

Without further ado, ThorntonWeather.com’s sneak peak of the episode.  In this scene small pieces of debris fall from the sky after meteorologists Danny and Aaron track down a funnel cloud in Rock Valley, Iowa.

Snow on Halloween more fact than fiction

Leave a comment
Snow on Halloween? Popular belief is that we seem to have a lot of snow when the trick or treaters are out on the street.
Snow on Halloween? Popular belief is that we seem to have a lot of snow when the trick or treaters are out on the street.

Conventional wisdom in the Denver area is that it always seems to rain or snow on Halloween.   I know as a kid it seemed like Mother Nature always put a damper on our trick or treating. 

But, is there any truth to this urban legend?  Or is this just one of those times where our memory doesn’t serve us quite right? 

This year it certainly looks like we have nothing to worry about but  the National Weather Service has been kind enough to compile weather statistics just for Halloween.  As it turns out, the thought of snow and rain on Octboer 31st isn’t just in our minds!

A Preview of Denver's November Weather - Will it be a Fall Month or a Winter Month?

A preview of Denver’s November weather – Will it be a fall month or a winter month?  Typically November is a quiet weather month with plenty of nice, fall days but it can also turn wet with plenty of snow and moisture.  Just like Forest Gump’s proverbial box of chocolates, you never quite know what you are going to get.

Looking into the weather history books, we see that November is actually Denver’s second snowiest month, second only to March (April is third).  Historically we average 10.7 inches of snow during the month.
