.DISCUSSION...
(This evening through next Sunday)
Issued at 1208 PM CDT Mon Jun 29 2026

A hot and humid day is occurring across the Mid-South as
temperatures are already approaching 90 degrees with surface
dewpoints in the 70s. Visible satellite trends show some
diurnally based cumulus developing with sunny to mostly sunny
skies prevailing across the area.

A 595 dm upper-level ridge currently centered over portions of
the Lower Mississippi and Tennessee Valleys will bring prolonged
very hot temperatures in the middle 90s to around 100 degrees
this week. A combination of these very hot temperatures and high
surface dewpoints in the middle 70s will result in heat index
values ranging from 105 to 109 degrees through Tuesday. Dry
weather is also expected to persist through Tuesday.

Short-term model trends suggest moisture will increase for the
latter half of the week as low-level moisture on the southern
periphery of the ridge drifts into the Lower Mississippi Valley.
This will bring a low chance (15-30%) of afternoon and evening
pulse-type showers and thunderstorms driven by peak heating. Any
convective activity will only bring a temporary relief to the
dangerous and oppressive heat.

Uncertainty still remains with the potential for some locations
reaching Extreme Heat Warning criteria for the latter half of the
week. Latest guidance has trended slightly cooler with high
temperatures which would keep most if not all of the area in
advisory criteria. Thus, in coordination with surrounding offices
decided to keep the Extreme Heat Watch in effect for the time
being and reevaluate headlines over the next 24 hours. Convective
chances into the Fourth of July weekend will increase modestly as
the high pushes east to the Mid-Atlantic states.
