No I think it's legitimate that, maybe not to that extent, but these gradients are so tight!
I have different people and in particular a church just near Short Pump, who want me to weigh in on what they should do about church Sunday. I told them pretty much what you said to just stick to the national weather service maps right now. Which Wakefield has 1.7 inches currently forecasted for Richmond, and a little bit more as you go south towards Petersburg.
But man just a 20 mile jog north and it's a whole different ball game!
