Rain is expected to start about 7:00 p.m., but radar indicates the rain will probably start later. Rain is expected to change to snow about 8:00 p.m., but again that may be delayed by timing and because air temperature is slightly above forecast. Snow probably won’t get going until after 11:00 p.m.
