Have you felt a rain drop or become drenched at any time
over past few weeks?
If so, please ignore.
This graph shows median daily rainfall for the period from April 1st to June 30th, as calculated from 1998 to 2012. As you can see, regular "day after day after day" afternoon showers typically do not start until the mid or latter part of May. That being said, we'll need some period spring rains to tide us over to the wet season. Looks like some could be on their way this weekend, too.
The summer rainy season doesn't start until mid May.
