I recently got certified with the Weather Office in Jackson (KY). I'm usually relaying pictures and reports to them, from snow to severe weather. In the eastern part of my county, there is no one other than me (that I know of) really interested in weather, or being a spotter. Since I live in the far western part of the CWA, I kind of consider myself the "test dummy"

or first line of defense. The storms have to go through us to get to our east.
In eastern NC (MHX), I helped verify a storm producing hail, and reported a wall cloud. In Va I prompted a special weather statement after reporting 40 to 45 mph winds (I had to call the weather office in NC and ask them to relay, as I didn't have the office in Va's #). In NY, I sent in snowfall totals, and was one of the reasons a winter weather advisory was upgraded to a winter storm warning. I also verified what was coming down, as we had several freezing rain episodes, where a degree or two was the difference between a cold rain, snow or freezing rain.
Weather is certainly a fun hobby, and letting the NWS know what is going on (especially if you are far away from the office, or no one is in your area) can really help with warnings or other statements, and are just as important for verification of warnings, radar rainfall/snowfall estimates, etc.
