What city experiences the most rainfall or the most thunderstorms? I thought that it would be interesting to come up with … Read more
Determining the type of supercells that may occur within a given severe weather environment is important for a multitude of reasons. A supercell is a thunderstorm that rotates. There are three types of supercells: low-precipitation (LP), classic, and high-precipitation (HP). The configuration of the wind shear profiles within a severe weather environment is critical in diagnosing … Read more
On the evening of Sunday, March 26th, 2017, severe thunderstorms affected portions of southern Oklahoma and North Texas. These storms were scattered, as predicted in our forecasts leading up to the event, and many people received no rain. We also expected that thunderstorms forming along the dry line would quickly develop updraft rotation (i.e., become … Read more
On the afternoon of March 24, 2016, a stunning mesoscale convective vortex (MCV) formed within a mesoscale convective system as it moved over southern Alabama. I created the animation below using a sequence of radar images provided by the College of DuPage. What is an MCV (Mesoscale Convective Vortex)? An MCV is an area of … Read more

Nearly the entire state of Kansas, excluding the extreme western parts of the state, were impacted by a low-end squall line. I spent the … Read more
On Monday, March 7th, 2016, a spectacular supercell formed in far northwestern Oklahoma and entered southern Kansas. A supercell is a thunderstorm that rotates. Conditions on Monday were favorable for a couple of supercells to initiate off the dryline in far western Oklahoma, and into western Kansas. However, given weak convergence along the dryline and meager … Read more
I typically do not share model data because they can be very complex. I do want to show one of the state-of-the-art programs that I use in my operations to analyze model-simulated soundings. The models do not automatically compute these data; the additional software turns the raw output into meaningful information. At least one of … Read more
This phenomenon is NOT unusual, but it doesn’t always happen. Today, the dry line and the resulting squall-line were perfectly aligned. The data presented a teaching moment that I couldn’t pass up. At the end of the animation, I zoom in so you can see the wind barbs pointing toward the dry line. The air … Read more
