intensify over the next several days. Please see the latest river
flood warnings and statements for details.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

Two separate storm systems will move through the area Wednesday
night through Friday morning. There is some uncertainty regarding
the track of each storm which will determine precipitation type.

The first storm may produce light snow Wednesday night that
changes to rain on Thursday.

Thursday night into Friday morning the second storm system has
the potential to produce snow, sleet, and freezing rain.

Friday night through Saturday night two more storm systems will
move through the area. The tracks of both storms are uncertain but
the potential is there for rain changing to snow at night.

Flooding is expected on many area tributary rivers. Please see the
latest flood statements and warnings for details.
