Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
155 PM EDT Friday, March 20, 2015
Low pressure now entering WV will exit the Ohio Valley later today, gradually
taking accompanying moisture with it. Light rain and snow showers currently
in progress over the eastern basin will come to an end completely overnight.
Quiet conditions are then expected for the next several days. The next
significant disturbance in the Ohio Valley will arrive around the middle of
next week. A cold front could bring heavy rains and even some thunderstorms
Wednesday into Wednesday night.
...FLOOD POTENTIAL DISCUSSION...
Some minor flooding is lingering in the Muskingum watershed in central
Ohio, otherwise flooding is confined to the lower end of the Ohio Valley.
This includes the lower parts of the Wabash, Little Wabash, White, East Fork
White, Green, and Ohio Rivers. A handful of locations remain above moderate
flood stage. Flooding could linger in some of these areas for at least
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain showers (and some wintry precipitation north) produced a few
hundredths up to 0.25" across the northern and western basin. Amounts were
heaviest in the southeast basin where 0.25" to 0.75" was observed.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain (and some snow in the NE) will linger today in the eastern basin. Up
to 0.25" additional precipitation is expected. Elsewhere, conditions will
begin to dry out. A weak system crossing the Great Lakes could bring a few
hundredths to the northeast basin on Day 2 of the forecast as well.
