Another day of storms in the central U.S.

In our last blog post (https://communitycloudatlas.wordpress.com/2015/04/03/kicking-off-a-stormy-u-s-spring/), we shared some photos from the stormy start of the severe weather season in the central U.S. (24 March 2015). Large cumulonimbus grew over portions of Oklahoma, Arkansas, and Missouri, producing large hail in some locations. On the next day (25 March 2015), another round of severe weather would bring the first reports of tornadoes for the year.

There has already been an excellent summary created for this event that describes the atmospheric conditions and storm timeline: http://www.ustornadoes.com/2015/03/27/the-science-behind-the-oklahoma-and-arkansas-tornadoes-of-march-25-2015/

Earlier in the day, before the storms formed, mammatus clouds were observed over the National Weather Center in Norman, Oklahoma. Dena Grose shared with us her excellent photo, showing these bulbous clouds that can form when the air is much drier below the cloud deck.

While there were severe storms later in the day, these mammatus were not associated with any storms. This is confirmed by looking at the corresponding radar image from this time.

As time went on, a cold front provided the necessary lift to produce storms later in the evening. Matt Wing shared with us a picture of mammatus clouds, this time over Tulsa just prior to when a tornado warning was issued. In this case, the mammatus were indeed associated with severe storms.

Post-storm damage surveys indicated several tornadoes that moved through the Tulsa area. The strongest tornado was an EF-2 reported in nearby Sand Springs. Here’s a summary of the damage survey from the National Weather Service.

While Oklahoma experienced the worst of these storms, this unsettled weather provided beautiful views of turbulent skies over nearby regions. Shauna West sent us this picture from Pittsburg, Kansas.

Further south, over Arlington, Texas, Whitney Coker Terrell shared her turbulent view beneath a storm that same evening.
