DENVER — A warm and dry weather pattern greeted November across Colorado and will last for another day. Tonight will be partly cloudy and mild with lows in the 40s for lower elevations and upper 20s to middle 30s in the mountains.
Expect highs around 70 degrees Wednesday in Denver and across eastern Colorado. In the mountains, highs will stay in the 40s to around 50 degrees for another day.
A storm system will swing through Colorado Thursday and Friday, bringing more snow to the mountains and a mix of showers, thunderstorms and then snow to Denver and the eastern plains Thursday and Friday.
A Winter Storm Warning is in effect for the San Juan and La Garita Mountains of southwestern Colorado for Wednesday night through Thursday - 6 to 12 inches of snow will fall in those areas.
A Winter Weather Advisory covers the rest of the mountains of central and northern Colorado - mainly west of the Continental Divide - 4 to 8 inches of snow is possible.
Showers and a few thunderstorms will develop on the plains Thursday afternoon, with a rain-to-snow mix Thursday night and Friday morning. The snow will likely be in the 1 inch or less range for the Denver area early Friday, with clearing skies Friday afternoon.
Although the most recent snowstorm dumped a lot of snow in the mountains and an inch or two over parts of the I-25 Corridor, it did not bring any measurable snow to DIA, where the official snowfall reading is taken for Denver.
The average date for the first official snow (at least one tenth of an inch) is Oct. 18. Last year, the first official snowfall was not until Dec. 10 — the latest on record since 1882. In 2020, the first snowfall was on Sept. 8. The earliest snowfall was Sept. 3, 1961.
The weekend will be dry and milder again, with highs back into the upper 50s Saturday in Denver and the lower 60s on Sunday.
