Temp Warning Alarm Clock

People who like to run in the morning usually like to do so because the temperature is still low. I like to run when it is approximately 60F outside. I want an alarmclock that I can set the 'acceptable time frame to wake me' if the temp reaches 60F in that window, it will wake me. If it does not, it will wake me at the end time (which would be the latest I should get up and still run). This would allow me to get as much sleep as possible, and still allow for a run. I would not want to be alerted if it reach 60F at any other time... only if it was between the times I state (like between 6am and 9am). Yes, this device would require a wire to go out the window to be able to tell the outside temp. It should also: * be an atomic clock so I don't have to reset the time * have a battery backup so that I don't lose my setting when the power goes out * allow me to set the alarm window for all 7 days of the week separately so that I can make it conform to my schedule without trying to remember to change it each day * be able to choose which hours it makes the numbers dimmer for when you are sleeping * allow for choosing which color you want the digits * have the numbers glow and the background be black, not the other way around
