Update, 6:30am, Thursday, October 29: The early winter storm that never seems to end continues to pound the city of Denver.  For the latest on the storm, please click here for the new story.

Update, 8:10pm: Colorado weather has its extremes and this storm certainly is shaping up to fit that bill. Snow totals are mounting with areas to the west and south receiving the most. In the Denver metro area, most areas have received at least six inches with most recording more and additional accumulations are expected overnight.

As the temperature has started to drop and traffic on the roads has decreased, snow is slowly starting to accumulate on roadways. Bridges and ramps are getting very slick and soon the rest of the road system will follow suit.

At Denver International Airport, most airlines have reported some cancelations and many arrivals and departures are delayed. Deicing operations are in effect so those flights that are getting out are slow in doing so.

Numerous school districts have already announced they will be closed on Thursday. Among them are St. Vrain Valley Schools, Adams District 12, Adams District 50, Brighton School District 27J, Jeffco Public Schools and Aurora Public Schools. Click here for a complete listing.

A Winter Storm Warning remains in effect for much of the state including the Denver area until 6:00pm Thursday. The storm system that is causing widespread problems is moving a bit slower than originally forecast and that will delay the end of the snow. An additional 4 to 8 inches of snow can be expected overnight followed by 3 to 7 inches more during the day on Thursday.

Total snow accumulations for the storm event will range from 14 to 28 inches are possible with up to 36 inches in the foothills west of Denver. On the plains accumulations will range from 6 to 12 inches and blizzard conditions are possible.

Chain laws are in effect for most Colorado mountain passes including at the Eisenhower Tunnel, Vail Pass, Berthoud Pass, Monarch Pass and La Veta Pass. US 287 is closed from Ted’s Place to the Wyoming border. In Wyoming, I-80 between Laramie and Cheyenne is closed as is I-25 from Cheyenne to Wheatland.

The best advice at this time is to stay home and avoid travel if at all possible. Needless to say, tomorrow morning’s commute will be a rough one for those heading to work. Please allow plenty of extra time and take it slow.

Update, 5:00pm: Snowfall rates continue to increase and it is spreading further to the east.  In the latest Winter Storm Warning update from the National Weather Service, they have said that the storm is moving slower than expected and that means the snow will last for longer than originally forecast.

As such, forecast snow totals have increased.  Accumulations from 14 to 28 inches are possible with up to 36 inches in the foothills west of Denver.  On the plains accumulations will range from 6 to 12 inches and blizzard condtions are possible.

Update, 4:15pm: The snow keeps falling and the end is a ways away yet. Roads have been wet and slushy to this point however as the sun goes down and temperatures drop we will see more accumulation and icing of the roadways.  That, coupled with winds blowing at up to 25mph will create hazardous driving conditons across the Front Range. 

In the high country, US 287 from Ted's Place to the Wyoming border is closed due to adverse weather condtions.  Chain laws are in effect for most major passes including at the Eisenhower Tunnel, Vail Pass, Berthoud Pass, Monarch Pass and La Veta Pass.  In Wyoming, I-80 between Laramie and Cheyenne is closed entirely. 

At the current time snowfall rates are increasing and expanding from Denver north into Weld and Larmier counties and east of I-25.  Snowfall rates of 1 to 2 inches per hour can be expected for the next couple of hours in the hardest hit areas. 

Total snowfall accumulations are still forecast to be in the 10 to 18 inch range in the metro area and up to 24 inches in the foothills. Locally higher amounts may be seen in some areas.  See below for a snowfall forecast map.  Also see below for the latest storm reports from National Weather Service storm spotters.

Original story, 12:16pm: Denver’s October 2009 snowstorm continues in full force. Heavy snow has been and is currently being experienced across much of the Front Range. Storm reports from spotters are showing totals from 15 to 20 inches in the foothills and 5 to 8 inches across many parts of the metro area.

Winds will be increasing as the day progresses making what are already tough driving conditions worse. Needless to say afternoon rush hour is likely to be a big mess as moderate to heavy snow will continue to fall.

Total snowfall accumulations are still forecast to be in the 10 to 18 inch range in the metro area and up to 24 inches in the foothills. Locally higher amounts may be seen in some areas.  See below for a snowfall forecast map.

There are reports of tree branches breaking on trees that still have leaves and this will continue to be a problem. Power outages are also a possibility as the snow sticks to and weighs down power lines.

At Denver International Airport, some airlines have canceled flights including United, Frontier and Southwest. If you are flying out today or tomorrow or are expecting someone to arrive, check with your airline before going to the airport.

A Winter Storm Warning is in effect today lasting through 6:00pm Thursday. The warning area includes not only Denver but much of northeastern Colorado, the mountains and the Western Slope. Winter storm conditions will prevail throughout today and most of Thursday so things are only going to get worse from here on out. Please be careful! Travelers should check the Colorado Department of Transportation site for the latest road conditions and closures.
