Temps are predicted to be in the 70s today in the Piedmont. The dewpoint right now is 56.
If your shop and tools are still cold (56 or lower) from last week's cold temps they will condense water and create dew from the warm humid air.
If you need to open up your shop today, better heat it and your steel and cast iron tools up to >56 before you open it or they will have rust. No towels or fans will prevent the condensation, but a liberal fresh coating of WD40 will act as a barrier (Water Dispersing). Heat it up or keep it closed.
