The conditions would include:
- Warm waters, usually found in late fall and early winter
- Cold winds blowing over the proper fetch of any given body of water
These conditions were met this morning near the lakes north of Springfield.
Lake effect snow can be brought about when cold air blows over a large fetch of relatively warm water. The air both picks up warmth and humidity, leading to an unstable condition in the lower atmosphere.
The Springfield National Weather Service sent out a tweet which shows the “lake-effect” clouds and light snow nicely!
Lake effect is only for the Great Lakes, right? Not quite-check out the clouds coming off our lakes this morning! http://t.co/Ezgpvwg1al
