With the Thanksgiving holiday approaching, travelers cast a wary eye on Denver’s weather and in our look back at this week in Denver weather history we see they have had cause for concern in the past. Snowstorms and wind have caused their share of problems. Also notable, it was 140 years ago that Denver’s first official weather observation occurred.

In 1930…a major storm dumped a total of 13.6 inches of snowfall over downtown Denver. Most of the snow…9.4 inches…fell on the 19th when north winds were sustained to 23 mph. This was the only measurable snow of the month. Temperatures hovered in the 20’s and lower 30’s.

Winds to 60 mph produced 5-foot drifts paralyzing the city as temperatures hovered in the 20’s. While small airports closed…Stapleton remained open…but with long delays that snarled thanksgiving holiday traffic. Schools and businesses closed and postal deliveries were delayed. Almost all major highways leading out of Denver were closed to traffic for periods of time on the 20th and 21st. Most of the snow…13.5 inches…fell on the 20th.
