When does winter start in Oklahoma City, OK?

Question

I'm not talking about the exact date, but when does the bad weather start coming. When does it start getting cold like you need a sweater? :)

Answer 1

That varies from year to year. You probably  won't need a sweater until it starts getting cooler in late October. If you look at the averages, January is the coldest month. However I live in the Midwest and know there is no such thing as an 'average' year.
