Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1000 AM EST Friday, December 26, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
High pressure centered over the southeastern Ohio Valley today will keep
conditions dry.

This high pressure will be pushed to the east as another low pressure system
approaches from the west early on Saturday. An associated cold front will enter
the basin from the west around sunrise on Saturday. This front will progress
east through most of the basin by Sunday morning, though it is expected to
stall over the far southeastern Ohio Valley. Another area of low pressure will
move along the front on Sunday and exit to the east with the front by Monday
morning. The precipitation will exit to the east soon after.

Most dry conditions will then prevail until another weather system approaches
the region late next week.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding is occurring in portions of the Little Wabash Watershed.
Elsewhere no flooding is anticipated.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Very light rain and snow showers fell were scattered over a large portion of
the Ohio Valley. All basin averages were less than 0.10 inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...

increase to the southwest with totals ranging from 0.25 to just over 0.50 inch
in southern Illinois, southern Indiana, western Kentucky and middle Tennessee.
