Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1210 PM EDT Saturday, May 27, 2017

Showers and storms will affect the Ohio Valley today, especially in the south
and west portions of the basin.  A low pressure system will move through
the southern Great Lakes from west to east on Sunday. An associated cold
front will push through the basin with it. Storms are expected ahead of and
along the front.

During the early part of the upcoming week, most of the unsettled weather will
have pushed southeast out of the basin, while a large area of low pressure
remains north of the Great Lakes. This will leave the Ohio Valley in between,
with below normal chances of rainfall. The latter half of next week appears to
return to unsettled conditions.

Minor flooding is occurring or forecast across western and northern Indiana,
and isolated moderate flooding continues in portions of northern Indiana.
Forecast rainfall over the weekend is not expected to produce flooding in
other areas, but if rainfall heavier than expected falls across the northwest
Ohio Valley, some new minor flooding is possible.

Rain fell across the northern Ohio Valley. Heaviest basin average amounts fell
over east central Illinois, northern and central Indiana, and western and
northern Ohio where they ranged from 0.50 to 1.50 inches.

Rain is forecast across the entire Ohio Valley. Basin average amounts are
forecast to be heaviest across the southern and eastern Ohio Valley where they
will range from 0.75 to nearly 1.25 inches.
