That will really depend on you and what you feel is to cold. Look up the weather norm for Mt Ida AR online. What I saw said lows around 32 and rarely below 18. For me not to cold, if I'm dressed right, fir my wife way to cold.
It gets pretty cold. Too cold for me. But a lot of people come out to dig. I've seen people out digging in the high twenties and low thirties.
