Is the fishing better in the rain?

[Raven]

also the temperature change and the PH change to consider as well.

Thunderstorms in the summer and lightning - the kind that roll in from the west after a hot day - no, I don't think the fishing is good after one of those and fishing during one is too scary. I don't think animals like thunder and lightning - I know it scares the heck out of Food Cat.
But rainy days in September are good - particularly around the lower bay.
Early stages of a moderate northeast storm, protracted periods of clouds and rain, etc, an approaching tropical low - are very good. (Pretty much what we're in for this weekend.) It's not the end of summer, but it's the beginning of the end. New patterns begin to emerge and I think the overcast kind of blurs the distinction between night and day and increases the duration of the dusk and dawn bites.
