Independence Day funnel clouds in Steamboat Springs
Saturday, July 5, 2014
Fireworks in Steamboat Springs started ahead of schedule on late Friday afternoon as funnel clouds appeared over the the south part of town around 5:30 pm MDT. These photos were taken on Village Dr, first near Meadow Lane and then about 1/4 mile north near Walton Creek Rd. As the radar loop from Grand Junction in the lower right shows, the storm rapidly gained strength soon after 5:09 pm MDT and was quite strong between 5:28 and 5:48. During this time, rotation was evident in several areas of the cloud base, and it appeared that 2 or 3 shallow funnels briefly formed around this time. Along with favorable wind shear that helped cause the rotation, atmospheric instability was enhanced as the storm formed along a dry-line that was present at the boundary of the moist monsoonal air to our south and some drier air to our north and west that appeared in the afternoon.
