Rainy Season in PNW. Can I throw down Urea while its raining or on a Wet Lawn?
What if any are the Ramifications? Procedures on doing so?
Im on 3rd weekly dose and upping to .5lb/k from .3lb/k but have had dry days to do so and then watered in.

You can apply it but if urea prills stick to wet grass blades it will cause localized burning. My recollection from my years in Seattle is that PNW rain/drizzle is not always vigorous enough to wash the pellets down off the blades, so you may have to water anyway. If you put it down while it's actively raining you may want a cover over the hopper.

It can also cause a mess, and possibly rusting, of spreaders. The combination of Urea and water seems to accelerate rusting.

I the prills are uncoated, U are better off liquifying the Urea
