I've discovered that this is not RPM related. If I try going directly from 1 to 3, revving up to 4k RPM, there is no grind because I'm going too slow. It is definitely speed related.

When rolling forward in neutral at around 40mph, I shifted into 3rd and GRIND. So, it seems to be some kind of synchro issue that is exacerbated by relatively high outside air temperatures. Once the temperatures backed off (the heatwave finally ended!), the shifting was back to normal.
