Ohio River Basin Hydrometeorological Discussion

1057 AM EDT Friday, August 29, 2014
A ridge of high pressure currently in control will gradually break down and
shift east of the Ohio Valley this weekend. This will result in deepening
moisture and increasing chances for shower and thunderstorm development. A
disturbance ejecting from the southern Plains will enhance convection
Saturday night and Sunday. A frontal boundary will then arrive late Monday,
which will stall over the region through midweek. This feature will keep
conditions unsettled until late in the work week when high pressure
is forecast to return.
...FLOOD POTENTIAL DISCUSSION...
Flood potential is currently low. Chances for localized flooding/flash
flooding will increase late this weekend into next week.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Some showers and storms were scattered throughout the western and southern
Ohio Valley. Overall coverage was modest, and amounts were generally light,
but localized totals over 2" were observed in spots.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Much of the western and central parts of the basin will see between 0.25"
to 0.75" with locally heavier amounts possible. Most of this rainfall
occurs on Saturday/Saturday night. Less than 0.10" is forecast across the
eastern third of the region.
