If the shop is warm long enough to get the tools warm, moisture will condense on the surface as they cool. WD-40 is great for sticks and squeaks, but it sucks for rust prevention. You need something more viscous and sticky that stays stay put on the tools to keep them from rusting. Chain lube like LPS makes will work much better. You might also try building a storage enclosure for the tools with a heat source in it. Even a light bulb (incandescent) will keep a small enclosure above the dew point. It would be sort of like a rod oven that welders use to keep their welding rods dry.
