DISCUSSION:

A storm system will move over the area through Sunday with
additional showers across the region. Additional rainfall amounts
between 1 and 2 inches is possible through Sunday, but amounts will
be variable due to the showery nature of the tail end of this
system. Peak rainfall rates between 0.25 and 0.50 inches per hour
will be possible. Another storm will bring light to moderate
widespread rain Sunday night through Tuesday. Yet another storm may
bring additional rain Thursday and/or Friday of next week, but there
are a wide range of outcomes in terms of rain and impacts.
