NOAA rain projections for Erie tonight are 0.02" So, I doubt it will mess anything up.
It won't make much difference which one you hit 1st Mucka, they will both be fine tomorrow unless some crazy amount of rain were to happen unexpectedly.
As for patterns, honestly, I'm more hung-up on presentation than specific patterns for Erie steelhead. It occasionally matters, but what always matters is presentation (especially in cold water). Had them take different eggs and different streamers today. There were a few nice fresh fish around. Fish what you are most confident with and put it where they live. You should have a good day!
