On Wednesday evening, a front extending from the Upper Mississippi Valley
to the Southern High Plains will move eastward to the Lower Great
Lakes/Mid-Atlantic to the Central Gulf Coast by Friday. The system will
produce rain over parts of the Upper/Middle Mississippi Valley on
Wednesday evening, moving into the Great Lakes/Ohio Valley by Thursday and
continuing eastward into Friday. Overnight Thursday, the rain will develop
southward over the Tennessee Valley into the Central Gulf Coast.

In addition, on Thursday evening, moisture from the Atlantic will stream
into the Mid-Atlantic, creating rain over the region overnight Thursday
into Friday. As the front moves eastward on Friday, rain moves into parts
of the Northeast and extends southward into the Southeast by Friday
evening.

Meanwhile, upper-level ridging over the West Coast creeps eastward into
the Plains by Friday. The upper-level ridging will allow temperatures to
be 15 to 25 degrees above average over the western third of the country.
