...HYDROMETEOROLOGICAL DISCUSSION...
High pressure is hanging on for one more day providing quiet conditions
across the basin.  Showers and thunderstorms will move into the western basin 
tonight as low pressure approaches from the west.  The low will cross the
region Saturday and Saturday night generating widespread precipitation in
the form of showers and thunderstorms. Heavy rain is anticipated. High
pressure will gradually build back in from the northwest late Sunday into 
Monday.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding remains across portions of southeast IL, southwest IN, and
western KY. Moderate flooding continues at two locations on the lower Green
River. River levels are currently falling. Potentially heavy rainfall this 
weekend could bring another round of minor flooding to the western basin,
and possibly to parts of the southern Ohio Valley as well.
