..Frost and freeze headlines

Clouds should clear out as the upper trough moves east, and with high pressure overhead, winds will become light and variable overnight. 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. Probabilities of less than 32 are much lower for some reason in west central MN from Elbow Lake up to Detroit Lakes, with chances 20 percent or less.Kept Grant, Otter Tail, and western Becker as frost advisory but have the rest of the CWA in a Freeze Warning.
