If I want to talk to Flight Watch to get an update on the developing
weather situation or give a PIREP, how do I do that? Do I need to
terminate the radar service with Approach, talk to Flight Watch, then
contact Approach again for further radar service, or is there an easier
way to accomplish this?

Just ask for a temorary frequency change to flight watch. They will
most likely grant it and say to report back. IN the rare event you call
just as they are about to transfer you to another controller, they may
ask you to wait for the transfer, or tell you to report on the new
frequency.
