Trent, I've found the el cheapo weather stations to be unreliable. I'm on my second one now.
My current one, a WH-3081, has a habit of locking up its USB connection and needing to have all power removed and then the clock reset to get it to talk to the PC. It's now a bit over a year old and the solar panel recharger only maintains battery power overnight if it got full sun all day.
If I was putting a weather station on an observatory I'd look at a wired Davis one. A lot more dollars though.
