On frosty morning 4 to 5 miles a day for 4 days will hardly have the engine at full temperature and 3 days sitting in the open does not help
Condensation contaminates the oil and cause the problem you have. As Oil and water do not mix you get this creamy mixture
I would go with the Oil and filter change and then a good long fast run of at least 50 miles, you would want to do it every second weekend if possible in the really cold weather to prevent the condensation build up
You might see smoke from the pipes and engine as the water spray and dirt will be burning with the full heat.
