On February 9 and 10, a significant snowstorm swept across Arizona and Colorado, with ongoing snowfall anticipated through the weekend. Northern, central, and eastern Arizona are preparing for additional snow, with accumulations starting as low as 3500-4000 feet. In Colorado, the Denver metro area is facing snow showers with 1-3 inches expected tonight, and an additional 1-4 inches likely throughout the day. Greeley, Colorado, experienced a severe snowstorm, receiving 8-12 inches of snow in less than six hours, the most since October 2009. Snow levels near Globe, Arizona, have dropped to around 3500 feet, with light snow continuing. South and east of Denver are forecasted to receive 4-8 inches of additional snow.

Short-range models hinting at some especially heavy snow north of Denver tonight. Expect slick roads around most of the metro area tonight/tomorrow AM. Heading to bed- see you on @9NEWS in the AM! #COwx #9wx https://t.co/FmI8uDshLQ
7:05pm: Convective snow showers up and down the I-25 corridor…temps mostly above freezing, but these could put down a quick 1-3” of snow, mostly on colder surfaces. Still, watch for roads to get slick quick tonight! #9wx #COwx https://t.co/mIlM9QCBFY
Tough to get much snow in Denver when your surface low is in (checks notes) El Paso. Most of the snow from our weekend storm probably comes tonight, as a result. #9wx #COwx https://t.co/9jJc9neXTc

7:41am: Light snow/flurries over the south side of the metro area. Light accumulations and slick roads possible, especially above 6000’ this AM (mainly along/south of 470). #COwx https://t.co/ihqMCSkqF1
🌨️ Mostly cloudy with a chance for snow showers this AM (mainly south of Denver), and a better chance for snow after ~4pm. 1-3” of snow likely for most tonight, with more likely tomorrow/tomorrow night. #COwx https://t.co/AqwnstTBvy
The snow event is over for now, take a breather. It is important to know that snow will return to portions of northern, central and then eastern Arizona later today, tonight and Saturday. Here our expected snowfall, note the snow accumulations as low as 3500-4000 feet. #azwx https://t.co/3t5gjyYdDy
