.DISCUSSION...
Issued at 132 AM CDT Sat Aug 2 2025

Through early next week: Though summer isn`t going away by any
stretch of the imagination, we will have a much deserved break from
the extreme heat stress that has plagued the area over the past
several days. A building upper trough over the eastern CONUS will
nudge a front southward through the area over the weekend, bringing
more seasonable conditions to much of the area. We`ll begin to see
60s dewpoints infiltrate the northern portion of the area by later
today, advancing farther south and east into the area on Sunday.
With temps closer to seasonal norms, this will yield heat index
readings within a more tolerable range over the coming days. The
only caveat may be south MS and central LA where heat index readings
will still be close to critical thresholds today before (relatively)
drier air arrives tomorrow.

With respect to rain chances, a decrease in deep layer moisture over
the northwestern half of the area will curtail rain chances, while
scattered convection will still be possible across south and
southeastern zones today. This theme will persist into early next
week, with more of a shift to a dry west/scattered PoP east
orientation by Monday.

Late next week: The mid level ridge will begin to build into the
Deep South again toward the end of next week, resulting in
rebounding heat across much of the area. Humidity will also begin to
creep back upward, and by Wednesday, heat stress could become a
greater concern again, especially over the western half of the area.
Over the eastern half, temps will be more marginal owing to greater
prevalence of clouds and scattered convection. /DL/
