We use windandweather.com they have great quality and are great to deal with.

I did some online research and discovered that the thermometer must be placed in a shaded area with adequate air circulation and preferably 4 -6 feet of the ground in order to work properly. I am looking into a weather station, and setting one of those up properly opens up another can of worms, too, like placing the sensor in a Stephenson (spelling?) Screen. All this fun for getting outdoor temperature from the comfort of your house!

We gave up on dial thermometers. We now have a digital. The outdoor part hangs from our out door light fixture, under the eaves. The read out portion is inside and tells us max., min.,and indoor temps. We got it a a local big box store, and it was under $20.00

I got one from Brookstone for Christmas...it is wireless with no outdoor sensor; instead it gets the weather information from the National Weather Service at the airport.

I don't know if it reads a satelite signal or a radio signal, but I do know there has to be a local National Weather Service weather station nearby for it to be accurate or else you have to buy a subscription.

I keep it in the dressing room so I know how to dress for the day, but I could move the receptor anywhere. I would prefer to look out the window at a thermometer, but we have the same problem: a 50° day might show 110°! It was driving me crazy!

An alternate I am thinking about for the backyard is an outdoor Gallileo thermometer.
