I visited my family in the Bay Area last week, after a week of some of the worst weather all year; it stopped raining an hour after my plane landed, and did not rain again for the six days I was there. But while I was away, it snowed here in St. Louis, ending a spell of (apparently) unusually warm December weather.
My conclusion is that I must bring the good weather with me where I travel. The weather report says that it’s going to be warmer again here for the next week, so that’s a good sign.
On the other hand, posting about this here is probably just asking for trouble.
