.DISCUSSION...
Issued at 1220 PM CDT Wed Jul 30 2025

High pressure is expected to dominate over the region through the
middle of next week, which will result in hot and precipitation-free
conditions with heat risk concerns, especially heading into the
weekend and early next week.  Heat indices could exceed 111 degrees
in some areas between Friday and Monday, which could potentially
warrant heat advisories on these days.  Current guidance is showing
that inland portions of the eastern counties (particularly Kenedy
and Willacy) are most likely to be impacted by potential heat
advisories, since the humidity will be higher in these areas due to
coastal proximity.

High temperatures should be in the upper 90s/lower 100s through the
middle of next week.  Low temperatures will consistently be in the
mid to upper 70s. Winds will diurnally cycle between being more
southerly during the day and more southeasterly overnight, but
should remain light to moderate.
