Here in the mid Atlantic states on the east coast. Maybe better to check tomorrow only, Sunday? huh? Just a concern about battery and being a older car with miles on it.
Don't start a car just to start it unless you will get the engine and exhaust to temp. Connect a temp compensated float charger if you want to keep the battery fully charged.
This like a block of steel or a car that do not produce heat are not ffected by windchill. If the car gets to say 10F and the wind picks up making the windchill -20F but the temp is still 10F, the car will be also be 10F.
Now if the temp drops from 40F to 0F in an hour, the temp of the car will not drop that fast so wind will pull the heat away quicker cooling it down faster than if there had been no wind, but once the vehicle is down to the ambient temp, windchill makes no difference.
