.DISCUSSION...

Shower chances will be limited through the first half of today. Showers
become likely later this afternoon with a few thunderstorms possible as
well. At this time however, showers may arrive late enough in the evening
to keep lightning chances pretty low, so have decreased that probability
with the latest forecast update.

Drier air will return through the day Sunday and continue into the
middle of next week. High pressure, responsible for these drier
conditions will push offshore during the middle part of next week.
Warmer temperatures will ensue.
