Today should be the last day this week with air temperatures in the high 80’s.  We should get a few storms moving through late this afternoon dropping the air temperature and leaving around 1/4″ of rain.  That should soak in the ground.  The clouds will be a great help this afternoon whether you’re nymphing or looking for risers.  The best bet for dry fly action is the Upper West Branch but evening may pick up on the lower sections once the clouds and rain showers start.  Nymphing has been better on the lower sections because there is less algae floating in the water column.  The algae should filter out and become less of a problem with the higher release.  It may take a couple of days to filter through.
