What is the weather of Yunnan in June?

It is getting warm in these places in June, but there will be large temperature gap between daytime and nighttime. And it will be a little cool in Shangri-la, which has lower temp than other places. Rainy days are very likely to happen in all destinations, so raincoat or umbrella should be prepare. For clothing, I'd suggest you prepare leather jacket & a light jacket, long-sleeved shirt & T-shirt and jeans.
