9NEWS Meteorologist Ashton Altieri says precipitation is likely by late Tuesday along the urban corridor but it could be rain or snow for locations below 6,000 feet. If snow does develop around the Denver area, any accumulation will be very minor and should be limited to grassy surfaces, rooftops and vehicles.

In addition to the chance for the first snowfall of the season in Denver, temperatures will be much colder starting Tuesday. After highs in the middle and upper 70s on Monday, temperatures will drop into the upper 40s on Tuesday.

Ashton expects it to be cold enough in the Denver area for rain to change into snow by Tuesday evening, but the very warm ground will make it difficult for accumulation to occur.

The forecast for the mountains is much less complicated.

The National Weather Service has issued a WINTER STORM WARNING for mountain northern and central mountain locations west of Vail Pass through 6 p.m. Tuesday. Locations in the warning include, but are not limited to Vail, Snowmass and Crested Butte where 6 to 12 inches of snow along with 40 mph wind gusts will make for very dangerous driving conditions within the warning area. 

A WINTER WEATHER ADVISORY is in effect for most locations in the San Juan Mountains through until 6 p.m. Tuesday. Locations within the warning, such as Telluride and Ouray, can expect 4 to 8 inches of snow to accumulate by Tuesday evening.

A second system approaching from the southwest will bring a much better chance for snow showers to the Front Range by Thursday afternoon.

The last measurable snowfall in Denver was on May 12. The latest first snowfall on record is Nov. 21, 1934.

Stay tuned to the networks of 9NEWS for the very latest on this system.
