.SHORT TERM...
(This evening through Saturday night)
Issued at 230 PM CDT Fri Jun 27 2025

Convective coverage has been scattered through the day across the
region. Most locations have seen at least a shower or two if not a
thunderstorm. Late this afternoon most of the convection is
currently confined to areas west of I55. However, points east have
recovered a good bit so it wouldn`t be impossible for additional
convection to fire before sunset this evening east of the I55
corridor.

Through the period an upper level low will be situated over the
Florida panhandle and south GA/AL. This weakness will continue to
enhanced the diurnally driven convection during peak heating.
Coverage will remain scattered to numerous Saturday afternoon and
cannot rule out a strong wind gust or two as seen today. As for
temperatures, think that the highs will not get as warm as they
could with the low overhead and lower thicknesses as well as the
rain chances during peak heating. However, that said, average for
late June is what is forecast, which even then the lower 90s are
favored. (Frye)

.LONG TERM...
(Sunday through Thursday night)
Issued at 230 PM CDT Fri Jun 27 2025

Going into the medium range the overall pattern doesn`t change
very much from Sunday through the start of the new workweek. The
upper level weakness remains allowing for daily showers and storms
to develop during peak heating across the land-based zones. The
higher POPs/coverage will help mitigate temperatures a bit. Going
into midweek there appears to be a slight change to the upper
level pattern. A modest H5 ridge develops over the region, which
will change a few things that need to be highlighted. First, the
coverage of showers and storms will again decrease. As this
happens the potential for warmer daytime temperatures, especially
with the modest high over the region increase. And with some
subsidence, dry air aloft will suggest a slightly higher wind
potential in the stronger and wider updrafts. At this juncture,
summer is the best way to characterize the next 3-7 days (and
even the short term as well). (Frye)

.AVIATION...
(18Z TAFS)
Issued at 1211 PM CDT Fri Jun 27 2025

Convective coverage and confidence is a bit higher today. Covered
this potential with TEMPOs (all but MCB) for reduced VIS/CIGs and
locally higher wind gusts around storms this afternoon. Outside
of convection light southeast or easterly flow continues with VFR
VIS/CIGs expected. (Frye)

.MARINE...
Issued at 230 PM CDT Fri Jun 27 2025

Overall, benign marine conditions continue outside of convection.
Light winds and seas on average can be anticipated. However, in
and around convection locally higher winds and seas can be
expected, especially during the overnight and morning hours. In
additional to the locally higher winds and seas, waterspouts
cannot be ruled out in the strongest updrafts. (Frye)
