Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1048 AM EST Monday, January 16, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
A warm front will lift northward into the Ohio Valley today. Some showers
have developed ahead of the front, but the bulk of the precipitation will
arrive tonight as a strong area of low pressure approaches the Great Lakes.
The low will drag a cold front across our region on Tuesday, although
temperatures will still remain above normal all this week.

A strong ridge of high pressure planted over the Southeast US will slow the
progression of the front down in the southeast basin, and a secondary wave
of low pressure will finally push it out of the region Tuesday night.
Rainfall could be heavy in spots, especially where thunderstorms develop -
primarily over the southern half of the Ohio Valley. There will be a brief
stint of dry weather midweek before the next system arrives for Thurs-Fri.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding from recent rains continues across parts of Indiana, eastern
Illinois, and northwest Ohio. More flooding is possible beginning Tuesday
as the next round of potentially heavy rain moves through.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain fell across the western, central, and southern Ohio Valley.
Amounts were mostly under 0.25" except in the southeast Appalachians and a
small stripe in southeast Illinois and southern Indiana with up to 0.50".

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast basin-wide. Most of the basin will receive 0.30" to 0.60",
however parts of the southern Ohio Valley could top 1" due to thunderstorms.
