I was supossed to do a long bike ride today - weather was perfect, upper 50s sunny with no wind. Left to go home from the barn at 1pm with above weather conditions, was still nice at 1:30, went outside to go at 2pm and the temp had dropped, wind up a bit, and cloudy - nothing on the radar. Went out and 5 miles in it started to sprinkle. By mile 7 I turned around. The temp had dropped over 15 degrees in less than an hour, and no weather report had predicted it. So inside onto the treadmill for another 3 miles. Unplanned brick, but it went well.
