The Ohio Valley is between weather systems today. Generally quiet
conditions are expected. On Wednesday, a broad area of low pressure will
drop into the region, bringing the chance of showers and possibly embedded
thunderstorms to the area - and keeping temperatures at or below normal the
rest of the week. The low will finally exit the region late this weekend.
Rain with this stubborn disturbance will not be terribly heavy, but will
persist for several days. The highest rainfall totals through the event
will likely be in the northeast Ohio Valley. Amounts here in western PA,
western NY, and northeast OH could range from 1" to 3". Elsewhere, around
0.50" or less will be common.
