.DISCUSSION...
(This evening through next Saturday)
Issued at 1215 PM CDT Sun Jun 28 2026

High pressure at the surface and aloft extends from the northern
gulf coast into the Atlantic. Hot and dry weather is resulting
from this setup. Temperature averages are running a few degrees
above climo normals and may increase another degree or two into
Tuesday which may push interior areas to near heat adv criteria.
Precip coverage, which generally is scattered in the afternoon, is
also running below normal. The ridge will remain in place through
Tuesday while a Saharan dust plume advects across the region.
Hot, dry, and hazy conditions are anticipated.

The ridge will shift northeast into mid week and become centered
roughly over the Ohio River Valley. While the ridge aloft weakens
locally, moisture will be driven west around the base of the
ridge. This will increase the chance of diurnal convection for the
second half of the week, and also decrease temperatures a couple
degrees.

Mainly scattered cu between 3k and 4k feet remain over the

During the overnight, some low clouds and patchy fog will be
possible for the KAEX terminals with MVFR conditions from roughly
29/11-14z. Otherwise, VFR conditions for remaining terminals.

A repeat on Monday with mainly scattered to broken cu developing
with daytime heating, however, ceilings will be mainly at VFR
levels.
