...HYDROMETEOROLOGICAL DISCUSSION...

A weather system is moving thru the upper Ohio Valley today producing light
to moderate rainfall. A secondary cold front poised to drop southeast
from the upper Mississippi Valley will bring much colder temperatures and snow
flurries on Friday to the Ohio River Basin. Then...high pressure will
produce dry weather to the area over the weekend.

Hydrologically...rivers/creeks are responding to the lastest
rainfall. Action stage rises are expected...as well as scattered
minor flooding in southwest IN and southeast IL.

...FLOOD POTENTIAL DISCUSSION...

Flood potential is slightly elevated in the lower Ohio Valley...and
remains low elsewhere.

1 to 1 1/2 inch rains hit the extreme lower Ohio Valley Wednesday
night. Elsewhere...1/2 to 3/4 inch rainfall totals were common in the
western half of the Ohio Valley.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
