On Friday, a stationary front lay along the southern edge of the Ohio Valley.
North of this front an persistent band of light to moderate rainfall was
affecting the southern Ohio Valley. This band of precipitation will oscillate
north and south somewhat through the weekend, but precipitation totals will not
On Sunday night and Monday the front will lift north as a warm front drawing
moisture northward again. Beginning Tuesday a very active pattern will return
to the Ohio Valley with various disturbances moving from southwest to northeast
across the region bringing significant amounts of rain. Details on the timing
and track of these disturbances are not obvious at this time, but the potential
for some excessive rainfall and resulting flooding are worth noting.
...FLOOD POTENTIAL DISCUSSION...
Minor to moderate flooding is already occurring in portions of northern
Indiana, northern Ohio, northwestern Pennsylvania and far western New York
where rains over the past several days have produced significant runoff. There
will be some additional flooding as this water moves downstream in Indiana, but
flood potential for new flooding elsewhere is low through the weekend.
There is potential for flooding over a more widespread area by mid-next week.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell nearly everywhere in the basin. Areas receiving more than 0.50 inch
of rainfall included portions of Kentucky, eastern Indiana, much of Ohio,
western Pennsylvania and western New York. Highest amounts ranged from 1.00 to
1.75 inches in northeastern Ohio and northwestern Pennsylvania.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation is forecast across the southern two-thirds of the Ohio Valley with
