.PREV DISCUSSION... /Issued 939 PM CDT Fri Oct 20 2017/

DISCUSSION...
Low level moisture continues to increase across the area this
evening. Isolated showers, and perhaps a rumble or two of thunder,
will remain possible overnight, but the main action will hold off
until near sunset Saturday. With the increasing moisture and
persistent south to southeast winds overnight, temperatures will
not drop off much more, and the going forecast lows appear
reasonable. No forecast update is planned at this time.
