Nimbostratus clouds form at the frontal boundary.
cumulus clouds
A Low Pressure System is the kind of system that allows clouds to form. When clouds form, you can get a cloudy day, with most low pressure systems, the clouds bring the rain.
stratus and cirrus
A front, or boundary between two air masses, is typically characterized by clouds and precipitation. The amount and type of precipitation typically depends on the temperature and moisture difference between the two air masses. Generally speaking, stronger temperature/moisture differences mean more clouds and precipitation.
