I know what a cold front looks like on this more 'raw' info. And high pressure systems and low pressure systems appear at certain strengths, located in certain locations and moving in certain directions, I can observe if it is cold. When the lines are tight around the low pressure system located east of you and a high pressure system is moving toward you from the arctic, I know it is a cold pattern.
Stuff like that.
For temperature I don't look at precip much. Those lines and high/low pressure indicate most of it.
I can see approaching cold/warm fronts, both from the precip colours and the density of isobars on the map, but I don't get the connection between that and prolonged cooler or warmer trends... as opposed to temporary (hours/days) cooling or warming.
I guess that's the art portion of the process, as opposed to my very basic understanding of the science...
