Temperature sensor location outdoors

I was hoping someone could give me some advice about the best location to hang an outdoor sensor so I have a close to accurate reading? I live in an apartment on the bottom floor and I have a patio. I want to hang the sensor out on my patio. The sun doesn't directly hit my side of the building so I don't think I'll have too many issues as far as that is concerned. When I hang it out there I try to keep it as far away as I can from the sliding glass door so any escaping heat doesn't affect it. It still seems like it's a few degrees warmer than it should be though. I'll check around for local temps and I always seem to be a few degrees warmer. I live in a suburb so it's not like I'm in the city where it can usually be a little warmer. Anyway, any advice on what to avoid and where I can hang it would be appreciated. Thanks.

Brookstone wireless 5 day weather forecaster help

I was wondering if anyone has one of these or knows anything about them? I just bought one a few days ago. I love it except for one thing. It updates VERY slowly. It's supposed to be receiving a radio signal from accuweather.com every 15 minutes for the latest 5 day forecasts and current conditions. I don't mind the slow updates for the forecasts since those don't really need updated every 15 minutes but the current conditions is a problem since temps change a lot. It seems to be sending me readings that are at least an hour and a half old. Anyway, if anyone has any advice on this or any info on accuweather.com's service concerning this, I'd really appreciate it! Thanks!
