I would say these kinds of weather stations are kin to the old indian rock hanging from a tripod. If the rock is wet on the north side its raining from the north. If the rock is covered with snow it is snowing outside etc...
The best solution for me is to keep tabs on the OTA digital NATL BROADCAST stations from the local town. I have very good luck picking up from 6-36 of these stations all in full blown high def mode. Usually there is one 24/7 weather radar channel.
Of course your best bet is to have a NOAH WX ALERT RADIO on 24/7 when camping off the power grid. They sound off alerts for the area you are in.
I like getting useful weather information of what might be heading my way so we can get ready for the bad weather situation. Camping in an OFF-ROAD POPUP can be exciting when going thru some bad weather with high winds.
Your personal weather station would be neat to play with but IMO it really is just something neat to have. Having a couple of hours lead time for me is a much better situation.
These are the two things I have on when we are camping off the power grid here on the East side of the US.
just my thoughts
