If actual temp is above freezing, but windchill is below freezing, will water freeze?

I once heard that "windchill cannot create ice."

If it is 35 degree f outside, and the weatherman comes on and says "35 today, but with windchill, it will feel like 30!" 

If it 'feels like' 30 to me, wouldn't it 'feel like' 30 to water? And wouldn't that water, upon feeling like it was 30 degrees, pretty much say to itself "that's my cue," and freeze?

This is actually kind of a dodgy question. The answer is that yes, the wind can cause water to freeze in these conditions, but not directly because of windchill.

Windchill only describes what happens to warm dry objects like people. If something is cold and dry, then windchill has no effect. It doesn't change the air temperature.

For wet objects, it is more complicated. Evaporation of the water requires energy, and this lowers the temperature. The lowest temperature a wet object can reach is called the "wet-bulb temperature". This can be several degrees lower than the "dry-bulb temperature", depending on humidity. If the wet-bulb is below 0°C, then freezing is possible.

Now in order for a wet object to get close to the wet-bulb temperature, there needs to be some convection to take the evaporated water away: There needs to be some wind.

So the wind can cause freezing under the right conditions, but it's not correct to say that this is because of "windchill".

*edit*: Just to point out that you can't neglect heat lost by radiation here. This is an important way that the ground/water can cool far below the air temperature.
