My mom always told me these are called mackerel clouds, that when the sky is full of dots and cottony, spotted patterns it means a storm is coming.
These photos are from several months ago, but I am posting them now in hopes that it will rain. Usually our rainy season starts in late October/early November and goes strong through March. Then we have a dry period for the rest of the year. It's no mid-January and we've not yet had any real rain this winter.
That looks like it may change, however, as the forecast is full of wet days starting tomorrow. I really, really hope this happens. For as much as I dislike cold, damp, dreary days it's making me depressed *not* to have them because there is no ignoring the strange changes in climate and what this means for our future.
