Over the body, any wool areas, it'll fade, grey and white will develop black specks. The hair areas, legs, ears & parts of the face, it will stay as seen. But it's hard to tell how much hair will stay or be replaced by wool.
Strange how the rain is settling into certain parts... we are getting it from the edges, and it sure has been sitting on top of areas.... Charlottesville and east are getting drowned as @secuono showed. North of Harrisonburg, 50+ miles north of me, has had plenty and even Staunton, 20 miles north keeps getting downpours and much much more than us. We are ina pocket that it seems to just skirt around. Haven't checked the rain gauge to see what we have gotten... heard a couple of showers and thunder but it has not set down on top of us.
Hope that the pasture does not get too flooded... and yeah, some sheep are not too bright sometimes. Glad you got them in.
