Or ham radio APRS folks have a little weather thing going:
https://aprs.fi/#!mt=roadmap&z=11&call=a/PARS&timerange=3600&tail=3600 One might have to click "All" and change the time parameters but if lucky, some
weather stations may show up (WX).
True, it's based upon a voluntary system but there might be trouble with a portable station out in the open due to vandals. I've driven by a remote NWS station out in the countryside and it has something like an 8 foot fence topped
with barbed wire to deter "molesters".
One doesn't need to be a Ham radio operator to use Google APRS and I'd encourage anyone use it to go to their launchsites and diddle with the "show all" and the time frame settings. If somebody has a home weather station nearby it could certainly help getting an idea of local conditions. Of course, if a launch site is way out of the way, there might not be any APRS weather stations nearby.
Another strategy could be if a club has like an old shipping container at their launchsite for storage they could consider mounting an inocuous weather station on top of the container and be certain there would be no "easy" way to climb to the top of the
container. If one could cut a waterproof access hole in the roof to run power wires up and down and perhaps have solar panels lying flush on the roof (not optimal I know) they could achieve a self contained WX station that wouldn't attract attention of vandals. The key would be to keep it as low key as possible to avoid attracting someone who would steal or destroy it. (Again, if the site is "way" out in the boondocks, vandalism might not be as much of a concern.)
Something like this would probably have to be SMS based (something I dont' know is even possible) or Ham Radio APRS based using solar or batteries. Could perhaps program to come on via a timer when desired to monitor the WX.
Of course the easiest would be if a local flier, who lives nearby, would get a Tech license and setup an APRS weather station from home. That could be done cheaply with any old laptop, a weather station and perhaps with a cheap Chinese radio or terminal node controller to hit a nearby digipeater. Or they could just connect the WX station directly to the internet via a computer link. I "think" a person doesn't have to be a Ham to connect a WX station directly to the internet
but don't hold me to that. Perhaps someone who knows might be able to comment? If using Rf on the 2 meter band on 144.390 to send the data to an Rf Igate which in turn would get it on APRS.fi (Google APRS) would take a
Tech license. Kurt
Well used google and got this on SMS:
https://www.instructables.com/id/Raspberry-Pi-Solar-Weather-Station/ I didn't see windspeed or direction on it. Would take some skills, building and programming to pull off.
