A cold front will approach from the west Saturday. It is expected to
pass through the basin Saturday night and Sunday. Widespread precipitation will
develop ahead of and along the front. Behind the front next week conditions
will be noticeably cooler and drier.

rain there. Another cold front is expected to move through the region by the
end of next week, but is not expected to produce excessive rainfall.
