Predicting the Weather Back in the 80's I was at a cocktail party with my cousin, Mike, who is a meteorologist. I told him that I had a theory that once the weather locked into a summer pattern you got rain on the same day each week. (I based this on the fact that I was playing on four softball teams at the time and two would be done in September and two would be done in November because they had more rainouts.)
His response was that at this latitude (the Northeast) the weather took seven days to go around the world, so it was the same storm every week!
If you want to use this observation to your benefit take note of the weather the last two weekends in June. If the weekends are rainy you would do well to schedule your parties or rounds of golf during the week that summer. In addition, watch for the rainy day or two during the week and schedule accordingly.
The same holds true in the winter, so much so that my daughters' high school numbered the days of the week so that the kids would not lose the same special every week due to snow. If Wednesday is day three and it is snowed out, then Thursday becomes day three.
Don't fight the pattern. Mother Nature always wins.
