Drain it NOW.
If you have access to the keys, close the drain and add pure 100% antifreeze ($10.00 a gallon at Walmart). Run the engine long enough to open the thermostat a few times.
If you do not have the keys, do as Matt said:
Drain it from underneath by using the radiator drain valve or by cutting the lower radiator hose. Replacing blown freeze plugs, radiators, or heater cores are not fun.
A later hose and a gallon or so of antifreeze is usually an easy job.
Why would anyone run an antifreeze mix at +5F in Iowa or anywhere?
