There will be a good setup for radiational cooling, and dew points currently in the low 30s over southern Manitoba should be down in our area by tonight. Temps should drop to near or below the freezing mark in most locations, with a 60 to 90 percent chance of 32 or lower for much of eastern ND into northwestern MN.
