.DISCUSSION...
Rain showers will continue over areas east of the Black Hills
through tonight though precipitation amounts are generally
expected to be under two tenths of an inch additional. For
Wednesday, low rain chances continue near the North Dakota border
through the morning, then with more sunshine across the western
portion of the area Wednesday afternoon, a few showers may develop
once again as slight instability develops over the Hills and
adjacent areas west and south. Beyond Wednesday, temperatures
will warm Thursday and for some areas Friday, but return to much
below average for the weekend, with additional rain chances and
more widespread wetting rain returning to the area.
