For completeness, I found that this command: sudo tcpflow -i any -C port 80 and src host [BRIDGE URL]
allowed me to see all traffic from the AcuRite bridge. Further fiddling revealed that the word "daily" only appeared as part of a line structured this way: "&rainin=0.00&dailyrainin=0.00" and the dailyrainin value could be extracted easily from that line. Since I'm doing my realtime display in the bash shell, that's all I need. Of course, if different conditions ever cause the bridge to spit out a line including "daily" in some other context, or if the line containing dailyrainin is ever formatted differently, my script will fail miserably.
