Last week, several part of the region recorded a frost on either September 13 or 14th. A few locations in north central North Dakota reporting temperatures near or below 32 degrees on both mornings. If your particular area survived those days with no crop damage, the next frost threat appears to be holding off until next week. One of the reasons that cold morning temperatures will be temperatures are not a great concern this week will be because on several occasions this week cloud cover will be in place during the overnight hours. Clouds are natural insulators and will keep the low temperatures from dropping too much, but on a negative note, those clouds will keep the maximum temperatures on the cool side.
