Oxygen at 4.6 — thunder building by afternoon.

Water's sitting at 66.6°F, right in the smallmouth wheelhouse, but dissolved oxygen has been running low all day at 4.6 mg/L, which will keep fish lethargic and harder to move. Thunderstorms are possible this afternoon with a better chance Wednesday, so earlier is smarter if you're heading out. Early Chinook arrivals are worth keeping an eye on, though I wouldn't count on them just yet.
