Winter brings on a whole new series of car problems. Batteries, heaters and ignition systems have to work harder. There are ignition coil packs and conventional spark plug wires that may conduct high tension electricity under normal "dry" conditions, but moisture and dampness may allow the spark an easier path to ground than having to "jump" across a spark plug gap. Ensure the engine cranks fast enough (good battery) after that look at the ignition system for moisture, clean and dry ignition components and see if that helps if it does isolate which component is effected by moisture.
