It sure can freeze at 50 and higher on a nice damp day. That’s if you’re flying a carbureted engined plane. Those old carbs will freeze right over at the Ventury and if you wait took long before pulling the carb heat it will soon get mighty quiet.
What temperature does water freeze at?

Regular Rock Salt (Sodium Chloride) can melt snow and ice down to a pavement temp of around -5F. It will melt a lot less snow and ice below 15 degrees but it still works. It works better when prewetted with something (thus the tanks you see on a lot of trucks around here now) by turning more of it into a brine upon application.
The other trick is it is the pavement temp that counts - not the air temp. On blacktop roads during the day, the pavement temp often runs 10 degrees warmer than the air temp, meaning melting happens even when the air temp is below freezing.
There is a lot more to deicing and snow control than just the air temp...

Then I spray washer fluid on and it freezes to the windshield!
Here’s a picture of frozen water droplets on my car at above freezing temps
You need a new thermometer or the one in the car is way off. Water does not freeze at 37f, really.
I saw somewhere that putting Vodka in the washer fluid helps it not freeze?

Any solute affects the freezing point of a particular solvent by the same amount regardless of what it is (on a molal basis).
Thanks for asking, J.

Depends on what pressure you "squeeze" it at.
