.DISCUSSION...
Issued at 1223 PM CDT Sun Jul 27 2025

The heat has returned this afternoon, and no doubt about it, the
humidity came to play as well. Temperatures are quickly climbing
into the low and mid 90`s across the region as a field of cumulus
bubbles under the influence of peak heating. Though convective
coverage will come nowhere close yesterdays, spotty and short
lived showers and thunderstorms will be possible across the region
through the late afternoon. This, like much of the diurnally
driven summertime convection, will fade through sunset with a
humid, but quiet overnight expected.

As referenced in recent days, upper ridging will continue to build
across the region into Monday, and with it will come a decrease in
PoPs through mid-week, and a noticeable increase in both
afternoon temperatures and heat indices. For now, elected to
extend the present Heat Advisory through 8 PM CDT Monday, as heat
indices through the afternoon climb above 105 deg F. Given the
pattern, instances of heat indices briefly hitting 110 deg F or
higher may be possible, with what looks to be more instances of
this through Tuesday and Wednesday. With this in mind, it is
certain that Heat Advisories will be carried through Wednesday,
but we may need to introduce and upgrade some counties/parishes
to Extreme Heat Warnings as heat indices at or above 110 deg F
may be possible for multiple hours. This will be monitored
closely in the coming days.

The good news through the end of the period is that there looks to
be some relief in sight for portions of the region with the
introduction of PoPs as early as Wednesday afternoon.
Deterministic support continues to suggest that as the
aforementioned ridge slides west, moisture rounding the eastern
side of the gradient will slide west across the Gulf Coast. PoPs
increase in coverage on the back half of the week (Thu/Fri/Sat) as
a frontal boundary is pushed south, with a strong surface high
working out of Canada.
