...HYDROMETEOROLOGICAL DISCUSSION...
Low pressure over the Great Lakes will linger the next couple days, keeping
rain and snow showers going across the north the rest of the week. Showers
will be enhanced to the lee of Lake Erie. Elsewhere, high pressure
building in from the west will keep much of the region dry into the
weekend.

Another weather system will cross the Ohio Valley on Sunday, followed by a
stronger disturbance late Monday/Tuesday.  Heavy rain will be possible with
the second system, particularly across the southern basin.

...FLOOD POTENTIAL DISCUSSION...
Flooding has recently ended in the Little Wabash watershed. The threat of
additional flooding will remain low this week through the weekend, but will
increase again next week.
