.DISCUSSION...

Issued at 330 PM CDT Sat Jul 26 2025

Significant heat will by far be the primary weather impact for
the forecast area as we go through much of the next week.

This afternoon through Sunday: The center of the subtropical high
over the southeast CONUS will move west across the forecast area
over the next few days resulting in dangerous heat stress once
again. It appears most of the area will be about at heat advisory
level Sunday and we have gone ahead and issued this, but held off
on a longer duration adisory/warning configuration. After fairly
good coverage of convective rainfall today, increased subsidence
near the high center should greatly limit convective covearage and
help to enhance the heat. The greatest heat stress however should
occur when the high center shifts to our west resulting in more
of a west to northwest low level wind trajectory. /EC/

Another disturbance pivoting around the ridge will arrive in our
region and settle as a weakness between ridging over the Southern
High Plains and just off the Eastern Seaboard as we go into mid to
late week.

This all means that rain coverage will decrease through probably
Tuesday, then rebound with deepening moisture Wednesday into late
week. And temperatures will climb to near 100 degrees by Monday
and especially Tuesday as this ridge, with its core pushing max
strength for this time of year, slides directly overhead. Expect
more impactful heat and stronger messaging will continue to be
needed for early next week, but heat will diminish a bit with
some again with the next wave in the later week time frame.

Scattered SHRA and TS will develop again later today, through most
areas excepting our northern zones;  mainly between late morning and
