Where we lived in California, "a chance of showers" meant "it's going to be cloudy" and as for the rain, it meant "there is a chance it will rain either somewhere else or overnight -- so don't plan on enjoying it, nyah nyah nyah!" =O(
Growing up here in Oregon, I remember the forecast always included a specific %chance of rain if they thought it would rain at all! The old standing jokes were:
In Oregon we have two seasons:
warm wet, and cold wet.
Last year 2,762 Oregonians fell off their bicycles
(...and keep in mind any of the above might be days that are in the mid-50s or the mid-80s, depending on the time of year -- and any of the above might also have a %chance of rain listed!)
