We're crazy weather nuts and love to look at forecasts, weather maps, etc. If you haven't already looked there,
www.noaa.gov has the most reliable forecasts. It looks like Indianapolis will get .4-.6" of ice and then a total of 1-2" of snow tonight and tomorrow. Probably the worst danger will be if the ice brings down power lines. They've known this is coming, so hoping that they're salting the streets already.
We had a gas fireplace in our old house, and it put out a lot of heat, but you should take a flashlight and look up the flu before you use it to make sure it's unobstructed. Great place for the kids to roast marshmallows! Also, if you have a gas oven, it will put out a lot of heat, too, and will work without power. It might need to be lit with a match (burners too).
With the kind of temperatures you'll be having, any food in the fridge will stay fresh outside if the electricity goes off. We've used our garage before to keep it safe from predators if the temp was low enough. Portable phones on land lines don't work without power, but cell phones can be re-charged in a car if you have a car charger.
Smart to plan ahead and pack the medicines, just in case! Hope most of this storm is less than expected!
We had an inch of snow or so,but it's bitter cold. Tonight wind chill of 22-32 below zero!!
