Well, if you're looking at the *total* QPF through that time (I'm looking at TT site), then yeah, it would appear like huge swaths of moisture because it's a total amount over all those hours. Sort of like a Jackson Pollock painting (I use the term "painting" very loosely, hahaha!). Much larger area then, of course, would be covered by something, especially when you get out in time. But if you're looking at the 24-h amounts, you should see more "motion" (for lack of a better word) as a system moves through...it will increase, then decrease, over an area for various 24-h increments.
