Ohio River Forecast Center, Wilmington, Ohio
1058 AM EDT Sunday, May 29, 2016
Deep trough in the middle of the country and amplified ridge centered over the
east coast is bringing warm, humid air to the Ohio valley. This regime is also
allowing periods of scattered showers and isolated thunderstorms to pop-up
through the Ohio River forecast basin. TN, and OH.
This ridge will be tamped down somewhat as a low crosses well to the north of
the basin on later on Sunday, but the airmass will still remain warm and
generally humid. This will be the status quo for the Ohio valley until a cold
front will finally make its way through the area late in the week, cooling
things down and sweeping out much of the moisture/humidity.
...FLOOD POTENTIAL DISCUSSION...
No flooding is expected at this time, save for an isolated thunderstorm laying
over a small, local basin for a irregularly long period.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Scattered areas of convective precipitation were observed through areas of
western OH, western PA, SW NY, and IN. A few of these small swaths had up over
an inch in localized areas due to the convective nature of the precip.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Scattered, spotty areas of precipitation could occur in many areas of
the basin. As is the nature of convective/summertime precipitation, however,
some areas will receive a healthy dose of quick accumulating rain while other
areas will not receive a drop. Today`s QPF is more concentrated in the central
basin where cores of a quarter to a half inch or forecast. Other area are
forecast to receive less basin-average wise, but local showers could produce
locally heavy totals.
