I'm just guessing ......but it sounds like it's starving for oil ....maybe low oil or low oil pressure ....and being very cold maybe oil is not reaching the lifters ....how long did you let the car warm up for ....and how long had the car sat before driving when you heard the noise ....maybe the next morning you didn't hear anything if the oil heated up and coated all parts .....like I said just guessing from a few things I have seen/heard before hope it isn't anything serious.
