1050 AM EDT Tuesday, July 26, 2016
A minor disturbance rolling across the middle Ohio Valley today will promote
rain north of the Ohio River. Rains in general will sag southward today and
overnight tonight as a front pushes southward through the basin.
High pressure over the northern basin today and tomorrow will significantly
decrease the areal coverage of showers and storms in that area.
By Thursday, a low pressure system is forecast to reach the western Ohio
Valley. Chances of showers and storms are expected to increase Thursday into
Friday and continue into the weekend.
Conditions are expected to be somewhat cooler and drier in the Ohio Valley
early next week.
...FLOOD POTENTIAL DISCUSSION...
Flood potential will remain low over the Ohio Valley this week....save for any
locally heavy precipitation where isolated thunderstorms persist.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell over all but the northwestern quadrant of the Ohio Valley. Basin
averages were generally not that high where rain fell, but in some areas where
storms were significant, they ranged from 0.50 to 1.50 inches. These areas were
mostly in western New York and in western Kentucky.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected to affect the southern two-thirds of the Ohio Valley. Basin
averages will be highest across far southern Illinois and Indiana, and much of
Kentucky where they will range from 0.75 to 1.10 inches.
