DISCUSSION...
Showers and embedded thunderstorms will increase in coverage
across the area this morning, and will persist today before
gradually ending from northwest to southeast this afternoon and
early this evening. The presence of deep moisture and the expected
slow movement of the showers and storms will result in the
potential for locally heavy rainfall amounts in excess of an inch,

receive heavier amounts may see flooding of low-lying areas such
as ditches, viaducts and other flood prone low spots.
A few strong to severe thunderstorms will be possible south of
I-80 from midday into this afternoon, with damaging wind gusts and
large hail the primary severe threats in addition to heavy
downpours.
