The state of Arkansas has pretty mild winters and can sometimes get to below freezing overnight and sometimes during the day.
But most times it stays above freezing during the winter in Arkansas and rarely does the temperature in Arkansas dip below 30 F although like I said it can sometimes.
In the state of Arkansas the temperature rarely dips below 49 F for the high in winter.
So although it doesn't stay really warm during the winter months and you still do need heating in Arkansas it doesn't get as cold as states such as Kansas, Colorado or other colder states.
