From the benchWith overnight rain and snow in the forecast, check clarity at your first run before you rig up — if the water has any color to it, shift to slightly larger, brighter nymphs like the Egan's Frenchie or Perdigon and fish the slower inside seams where trout will stack up out of the turbulence. If it's still clear, focus your morning on deep pocket water with a stonefly nymph bouncing the bottom, then transition to a tight BWO nymph setup in the tailouts as the air temperature climbs toward the midday window. With water at 47.8°F, the BWO hatch won't fire until the sun has been on the water for a couple of hours — don't rush it, and be ready to switch to a dry fly the moment you see fish rising in the flats.
