.DISCUSSION...
High pressure will remain in place across our region into the start
of the upcoming weekend. Temperatures will gradually increase a few
degrees during that time. Meanwhile, a low pressure system will
develop over the lower Mississippi River Valley late in the weekend
and move across the southeast early next week. A cold front
associated with this system will cross the region Tuesday, and
cooler air will spill into the area through mid-week.
