Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1006 AM EST Thursday, February 23, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
A low pressure system will exit the Rocky Mountains and move into the
central plains today. Ahead of this low, a warm front will develop over the
northern Ohio Valley, becoming a focus for light rainfall to develop. As the
low approaches the Ohio Valley on Friday, the warm front will lift into the
Great Lakes. Friday night a cold front associated with the low will reach the
western Ohio Valley. Strong storms are expected to develop ahead of and along
the cold front. The front will move through the basin Friday night and exit to
the east early Saturday. The front will push the unseasonably warm
temperatures out of the basin with more seasonable conditions returning.

A disturbance is forecast to move through the basin on Monday providing some
modest amounts of rainfall. Another more significant low pressure system is
expected to develop and move through the basin around mid-next week.

...FLOOD POTENTIAL DISCUSSION...
Rain over the next 48 hours will produce some significant river rises,
especially on rivers in northern and western Indiana and northern Ohio, but at
this time flood potential is expected to remain low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain affected the southeastern half of the Ohio Valley. Amounts were generally
light with basin averages less than 0.25 inch. Only portions of the upper
Kanawha Watershed saw basin averages approaching 0.50 inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected across the entire Ohio Valley. Basin averages will be higher
in the central and northern portions of the forecast area, with a range of
0.50 to nearly 1.00 inch. Most other areas will see 0.20 inch or greater,
while the southeastern Ohio Valley will be 0.10 inch or less.

...RIVER BASINS IN FLOOD...
None.
