|Frost Advisory in effect from 3am to 8am Monday 10/14|
If the object's surface temperature is still below the dew point but its temperature is above freezing, you would have dew.
While frost can do damage to sensitive plants, it doesn't necessarily kill them. A hard freeze, however, can. A hard freeze occurs when the air temperature drops to 28° or below. Here in the Quad Cities, our 30 year average first hard freeze date occurs sometime during the last 10 days of October!
