A weather system will affect Cincinnati Thursday and it is exhibit 1 as to the difficulty involved in forecasting. Here is the 3 day precipitation outlook:
That’s quite a weather system for the eastern United States. But look at Cincinnati. Here is a zoomed in picture:
The dark blue is 1/2 inch of rain. Note that the eastern suburbs are projected to get 3/4 inch while Brookville in southeast Indiana would barely get 1/2 inch. Last night, projections showed Brookville barely getting 1/10 inch. For a weather system this large, 48 hours out, only a small wobble could mean a big difference. This difference is actually magnified if snow is expected, although any appreciable snow is not expected in this storm.
In any case, expect a wet Thursday afternoon and Friday morning, with minor variations if this system wobbles.
