i am a advocate of : AS MUCH OUTSIDE TIME AS POSSIBLE! i would leave him out 24/7 if i could. they are much healthier that way.
the other day we had tornado like winds with HEAVY rain. the horses with paddocks chose to stand OUTSIDE in the middle of it all! don't worry about your horse getting wet. standing in a stall with all that manure,urine and ammonia are MUCH MUCH worse for his lungs and hoofs. .
let him enjoy being a horse and outside :) if you're THAT worried. get him a light rain sheet ( no fill) as someone suggested.
however i would be much more worried about him getting too hot even in that.
