It was another mild day across Southern Idaho and we will remain mild and above average for most of the week. There is a chance of valley rain and mountain snow but most of that will take place during Tuesday night.

With the inversion still in place across southern Idaho valleys we could get another night of patchy dense fog in some of the same places. This fog will linger into Tuesday morning and temperatures will be in the low 30s in the valley to the low 20s in the mountains.

Storm system coming in from the desert southwest will increase clouds and bring a chance of showers to southern Idaho Tuesday evening and Tuesday night. Rain amounts could be around a quarter of an inch but this is mostly a night event. There could also be snow in some of the mountains and Wood River Valley. Amounts won’t be much with Hailey and Ketchum getting around a coating to maybe an inch.

System moves out Wednesday morning and could get some sunshine by the afternoon. Temperatures will remain mild into the middle to upper 40s in the valleys and upper 30s in the mountains. That trend continues for the rest of the week with more sunshine into the weekend.
