My wife got me a watch that tracks barometric pressure, has weather predictions, tracks elevation and has a compass.  It's quite handy for use in canoe country along with common weather tips like watching clouds and wind direction; face the wind and turn right 45 degrees and the low pressure is to your right to determine whether the weather system is coming or going.  East wind, rain is likely, north wind cold, south warm.  Also watch the cirrus clouds and for halos around the sun or moon.  It good to have a basic understanding of weather to help you plan your day or prepare hunker down.
