Back in the early 1990s here in Eastern California, our weatherman predicted “mostly sunny skies” for the following day in early March. We got two feet plus of snow. He was shocked!
My wife like to look at the extended forecast to see what the weather will be like a week from now. I look at it too, to see how often the forecast changes in the course of the week. The weather forecasters are at their best when they are tracking a storm on the ground. When they say the thunderstorm is going to hit my area at 8:31, I can pretty much count on it. Otherwise, not so much.
