Showers and colder air will move into the Four States tonight. Most of the showers will affect Northeast Oklahoma, Southern Missouri and Northwest Arkansas. It will be cold enough from Nevada through Fort Scott for some patch frost but most of us should stay in the upper 30 to around 40 for lows.
More widespread rain arrives Thursday night and Friday as an upper level low swings through the Plains. We could see over a half inch of rain through Friday night.
