.KEY MESSAGES...
Updated at 1111 PM CDT Sun Jul 27 2025
- Oppressive heat returns today and lasts through midweek. Heat
headlines are anticipated each day as heat indices reach and
exceed 110 degrees.
- Rain chances increase on Thursday ahead of a cold front.
Temperatures this weekend will return to normal.

.DISCUSSION...
(Tonight through next Sunday)
Issued at 1111 PM CDT Sun Jul 27 2025
Heat and humidity continue to be on the rise today as an upper
level ridge retrogrades across the Lower Mississippi Valley. An
Extreme Heat Warning will go into effect at noon for areas
along the Mississippi River & near the TN/KY border. Heat indices
in this region will soar above 110 degrees. Elsewhere, a Heat
Advisory is in effect for heat indices between 105 and 110
degrees.
Unfortunately, temperatures will only continue to increase on
Tuesday with highs in the upper 90s to lower 100s. In addition,
probabilistic forecasts paint a 50% chance of dewpoints reaching
and exceeding 78 degrees. This combination will lead to oppressive
heat, likely the worst thus far. Heat indices nearly areawide are
forecast to be above 110 degrees. For now, an Extreme Heat Watch
remains in effect for both Tuesday and Wednesday. Future forecast
updates will determine the location and timing of additional
Extreme Heat Warnings and Heat Advisories.
Luckily, an end to the heat is in sight. The aforementioned ridge
will continue pushing west through the end of the week, allowing
the Mid-South to return to northwest flow aloft. Rain chances on
Thursday will increase as a cold front approaches from the Great
Lakes Region. Areas along and east of the Mississippi River have
the greatest chance of seeing appreciable rainfall through Friday,
though rainfall totals will remain between 0.5 - 1.00 inches. The
upcoming weekend will feature near-normal temperatures with highs
in the mid to upper 80s.

.AVIATION...
(06Z TAFS)
Issued at 1111 PM CDT Sun Jul 27 2025
VFR conditions persist through the TAF period. Some VCTS will be
possible mainly across the east in the afternoon, but not enough
confidence to mention at any TAF sites for now. Light, SW winds
continue overnight and will become more W/NW by the afternoon with
speeds up to around 7 kts.
&&
.FIRE WEATHER...
Issued at 1111 PM CDT Sun Jul 27 2025
Fire weather concerns are not anticipated this period as MinRH
values remain above 50% and 20ft wind hover around 5-10 mph.
Wetting rain chances return on Thursday.
