Record warm temperatures on tap ahead of season’s first storm

DENVER -- The first storm of the season is expected to move into the Denver metro area and the Front Range on Thursday with a chance of rain and snow, but not before a warm day Wednesday that could set a record high temperature.

Temperatures are expected to surge into the upper 70s on Wednesday, threatening the record high of 77 set in 1941. It will be sunny in the morning, followed by the development of wave clouds that could take away some of the sun.

Winds from the southwest will kick up to 10-25 mph.

The mountains will remain dry with increasing clouds, breezy conditions and temperatures into the 60s.

A windy storm system will move across Colorado starting late Wednesday.  It will then quickly move over the mountains on Thursday and arrive along the Front Range and in Denver midday Thursday.

The storm will bring much colder temperatures along with a strong north wind.  It is possible for some light accumulation in the Denver area, but the ground is very warm and dry.

Denver has gone 35 days -- since Oct. 12 -- without any moisture being recorded at the official reading station at Denver International Airport. And that was only .01 of an inch. It has been since July since significant moisture fell in Denver.

In the mountains, accumulating snow of 2-4 inches or more at highest elevations is possible, which is good news for ski areas that have been missing out on snow.

Expect 1-3 inches of accumulation across the Palmer Divide and foothills, 4-10 inches in the northern mountains, 4-8 inches in the central mountains and 3-6 inches in the southern mountains.

Thursday's storm is the best chance to get some much-needed moisture and possibly the first measurable snow of the season in Denver.

In order to be considered a measurable snowfall, the National Weather Service will need to take three readings at DIA and record an average minimum of at least 0.1 of an inch.

With no snow forecast Wednesday, Denver has reached the third-latest snowfall of the season, behind only Nov. 19, 1931 and Nov. 21, 1934.

If no snow is measured with the approaching storm, then the record for latest first measurable snow in a season will fall to 2016.
