This is a weired winter. Last night we had a thunderstorm, High today was 59, low tonight is projected at 16. It is 24 right now and dropping. Really strange weather for January and central IL. I usually have the natural gas furnace shut off, so I go by the inside temp. not the outside temp. If it falls below 70 inside, the fire is going. Of course with this up and down stuff, I have to let it go out a lot. In my 63 years I don't ever remember a January like this. It is usually in the teens on average, and single digits or below 0 often in January, normally.
