Tornadic storm passes over Denver today

Today is May 20, 2014, one year after the Moore Oklahoma, EF5 tornado left a deadly damage path. This was also a day with tornado-warned storms in Nebraska, a fairly large and significant tornado-warned storm in Denver, Colorado, and severe-warned storms in Wyoming, Iowa, and Illinois.

The supercell that formed over Denver was significant, but fortunately, the storm did not become surface based, so the meso cyclone passed over the Denver metro area without causing reported tornado damage. NWS issued a tornado warning on the storm east of Denver.

Jonathan Merage was at his south Denver home, while tracking the storm's progress, when a fairly strong meso cyclone couplet passed right over his location (See slideshow). Jonathan took amazing pictures of the tornadic storm couplet.

Tomorrow is another day. The modeled jet flow is significantly higher and colder, and dew points are expected to be higher than they were today, between 50-55. With such added ingredients, tornadic storm potential is expected to be higher than today. The Storm Prediction Center (SPC) has issued a 'slight risk' for tornadoes in much of the northern and central Front Range area of Colorado for May 21, 2014.
