In my college days, I took a meteorology class, where I did a research paper on the nature and behavior of tornadoes.
The so-called "hopping" element of tornadic funnels is a common characteristic of these windstorms, one that is frequently observed and empirically decipherable.
For your sincere but uninformed in-law, here are a couple of basic explanations of what is taking place--activity which he is ignorantly misinterpreting as a "miracle":
"Tornadoes don’t hop, jump or skip. They can pull back up into the clouds and spawn again sometime later. They can carve a path through a neighborhood that spares some houses and demolishes others, leaving the impression the tornado skipped houses. While it’s true a tornado can completely destroy one house and minimally damage another right next to it, the reason has nothing to do with jumping or skipping.
"It has to do with the internal structure and varying intensity of a tornado and the path the tornado takes. The funnel of a tornado is sometimes composed of two or more vortexes which are just like smaller tornadoes that spin around in a circle. This kind of tornado is called a multiple-vortex tornado and is almost always responsible for narrow paths of extreme destruction. We normally can’t see the individual vortexes because condensation and debris obscure the internal structure and give a tornado that wedge shape appearance. . . .
"A large tornado’s destruction can vary significantly in just a quarter mile or so. As an example, one neighborhood might experience destruction consistent with an F3 tornado, but by the time the tornado crosses into the next neighborhood, the intensity might have dropped off considerably down to an F1. By the time it reaches the next neighborhood, it could very well have re-intensified into an F3 or greater. The neighborhood lucky enough to experience F1 strength destruction will suffer far less damage compared the to other areas that experienced the F3 or greater tornado intensity. This may give the appearance that the tornado skipped over a set of houses in one neighborhood while inflicting heavy damage both in front and behind it."

"Truth: It has been observed that some houses remain standing while other houses in the immediate vicinity are destroyed. Studies by Dr Fujita indicate that the main funnel will not touch houses in very close range but there are smaller funnels called 'multiple vortices' which appear to dart around the main funnel. If a house happens to be in the path of a one of these vortices, it can be destroyed."

What we observe with twisters behaving this way is not a "miracle" but, rather, typical tornadic activity that is well understood by professional scientists, therefore negating the need for magical interpretation conjured up by bamboozled believers in religious superstition.
