Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1211 PM EDT Thursday, May 25, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
On Thursday morning low pressure sat over the middle Ohio Valley. This low
will move northeast and be over New England by Friday morning. This will
provide a brief break in the weather before a disturbance moves into the basin
from the west early Saturday morning. Another low will move through the region
from west to east on Sunday.

During the early part of next 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.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding is occurring or forecast across southeastern Illinois, western
and northern Indiana. Forecast rainfall is not expected to produce flooding in
other areas.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell across the entire Ohio Valley. Heaviest amounts were in a swath along
the Indiana-Ohio border where basin averages ranged from 1.50 to nearly 4.00
inches. Other areas that received 0.50 to 1.50 inches included southern
Indiana, western and southern Kentucky, middle Tennessee, western Pennsylvania,
West Virginia and far western Virginia.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected across the entire basin. Forecast basin averages of 0.50 to
1.00 inch are expected in portions of Indiana, eastern Kentucky, Ohio, West
Virginia, northwestern Pennsylvania and far western New York.
