No temperature at all

Monday's high temperature of -2F marked the first time in just over four years that the high temperature of the day was below zero. No particular problem for me though, a person coming off the flu doesn't really spend any time outdoors anyway. It has been around 70 pretty much all the time where I have been spending my time. But just for fun today I caught a glimpse of the indoor outdoor thermometer.

As you can plainly see, there is no outdoor temperature at all.
