.SHORT TERM...
(This evening through Friday night)
Issued at 156 PM CDT Thu Jun 12 2025
Tonight through Saturday morning, the enhanced summertime pattern
continues. Scattered to numerous storms will be expected, mainly
during peak daytime heating hours late afternoon through early
evening. These storms will have the potential for frequent
lightning and gusty winds (40-60mph) inside stronger storms.
Locally heavy rainfall will also be a concern inside of these
storms as PW values are above the 75th percentile for SPC
sounding climatology, indicating efficiency. A quick 1-2 inches
will be possible, which could be an issue for mainly urban areas.
Temperatures will be in the mid 90s with heat index values in the
low 100s. The bulk of the best heating will be limited by the
rainfall. Still, it is always important to stay hydrated,
especially early in the season. MSW

.LONG TERM...
(Saturday through Wednesday night)
Issued at 156 PM CDT Thu Jun 12 2025
Saturday through mid week, still expect those daily summertime
showers and storms, but by Monday to Tuesday timeframe, should be
a little lower chances of PoPs. These scattered storms will
mainly be daily during the peak daytime heating hours, especially
late afternoon through early evening hours. Given the high PWs
remaining along with the abundant moisture, etc., these storms
will mainly produce the threat of frequent lightning and gusty
sub-severe (30-60mph) winds. There is still some uncertainty in
the coverage and PoPs of these storms, given it is still a while
out in time. So we will keep monitoring for changes.
Generally, temperatures will be in the mid 90s with heat index
values in the low to mid 90s, especially as we head toward mid-
week. So, be prepared to hydrate and take precautions as we head
deeper into the summer. MSW

.AVIATION...
(00Z TAFS)
Issued at 615 PM CDT Thu Jun 12 2025
VFR conditions across the area. Thunderstorms are diminishing as
daytime heating wanes, so VFR will predominate through the night.
Fog resulting in slightly lowered visibilities down to 4SM is a
possibility especially at the more northern terminals in the
early morning hours. Popup TSRA tomorrow with locally gusty winds
and lightning as daytime heating increases.
&&
.MARINE...
Issued at 156 PM CDT Thu Jun 12 2025
Winds will be benign for much of the forecast period. Winds will
be southerly and moderate (10-15kts) for the entire forecast
period. Showers and storms will be expected daily for the rest of
the week into the weekend, which could produce localized hazards
for mariners like gusty winds (40-60mph) and frequent lightning at
times. MSW
