Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
152 PM EDT Tuesday, June 18, 2013

...HYDROMETEOROLOGICAL DISCUSSION...
A disturbance moving through the southern Ohio Valley Tuesday morning will
exit to the east Tuesday afternoon. A cold front will then drop southward
from the northern Ohio Valley Tuesday morning and reach the southern Ohio
Valley on Wednesday. Another weak disturbance that will pass through the
Ohio Valley this evening may interact with the cold front and produce some
scattered storms late today.

Behind the front, high pressure will keep the Ohio Valley mostly dry
Wednesday and Thursday. By Friday the high pressure will move east of the
region allowing moisture to gradually return and temperatures to warm. With
more unstable conditions over the weekend, unsettled weather is expected to
return to the basin.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding continues along portions of the Tippecanoe and Wabash Rivers
in western Indiana.  The potential for any new flooding remains low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain was scattered across most of the Ohio Valley, but with limited amounts
in the north. Most significant basin averages were over far southern Illinois,
southern Indiana, Kentucky and middle Tennessee where they ranged from 0.50 to
nearly 2 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Nearly all of the precipitation in the forecast will occur before sunrise on
Wednesday. Rain is forecast over most of the basin, but the far northern
portion of the Ohio Valley will see only very light basin average amounts.
Amounts increase to the southeast with a range from 0.50 to 0.75 inches in
southern Ohio, West Virginia, southeast Kentucky and far western Virginia.
