.KEY MESSAGES...

- High heat and humidity return today through the weekend. The
  hottest day appears to be Saturday. Locations along the
  Missouri River into parts of northwest IA on Friday could
  reach 100 degree heat indices.

- An active weather pattern brings low chances (20-40 percent)
  for showers and thunderstorms late tonight through the
  weekend. Severe weather cannot be ruled out, but confidence in
  any details is low. Currently it appears the better chance
  for heavy rain and severe weather will be Saturday night into
  Sunday morning and mainly north of Interstate 90.

.DISCUSSION...
Issued at 227 PM CDT Thu Aug 14 2025

Upper level ridging builds into the area this afternoon and
continues into Friday. An isolated thunderstorm will remain
possible into early evening in southwest MN on the tail end of
the exiting wave but for now the higher instability lifting from
the surface appears to be capped while the elevated instability
is closer to 500-1000 J/kg. So brief heavy rain and lightning
would likely be the main threats if something can develop. A
weak wave is expected to move from the Rockies into central and
northeast SD tonight into Friday morning, which could bring a
few showers and thunderstorms. Convective development with this
wave may struggle as the low to mid level moisture should be
lacking just enough to leave a cap in place. This may keep the
activity most closely associated with the passing wave which
would bring some chance to areas mainly near and west of the
James River. There is enough instability and weak shear to allow
for an isolated severe weather threat, mainly half dollar sized
hail and wind gusts to 60 mph. Patchy heavy rain will also be a
threat with the freezing level around 13 kft. As the wave moves
through isolated showers and thunderstorms will be possible on
Friday morning.

As for the heat and humidity on Friday, areas south of I-90 will be
marginal for heat advisory criteria with heat index values right
around 100 near the Missouri River. One negative is that the model
soundings are indicting some moisture around 500-600mb which might
bring in some mid level clouds that could slightly limit the rise in
temperatures. Regardless, all areas will see afternoon heat indices
in the 90s with oppressive dew point temperatures in the 70s.

Upper level ridging continues to build into the area Friday night
into Saturday. This should keep chances for thunderstorms low with
the better chances north of I-90. There should be another wave in
western SD that will move towards north central SD, so if capping
holds, then much of the activity will be north of the area. Saturday
looks to have the better chance for more widespread dangerous heat
and humidity. Soundings indicate less concern for any cloudiness
that could impair heating and a plenty strong low level cap to allow
the dew points to climb well into the 70s.

Saturday night into Sunday appears to be the main time frame to
watch for potential strong to severe thunderstorm development.
Plenty of instability, about 3000 J/kg with weak shear. Models are
fairly consistent on bringing a bit stronger wave into central and
northern SD with a fairly strong 925-850mb LLJ that focuses into the
area, especially north of I-90. Right now the 925-850mb front runs
from right around I-90 at 925mb to just north of highway 14 at 850
mb. With fairly weak flow aloft suspect that motion would be east or
southeast if anything develops along this boundary so heavy rain,
ping pong ball sized hail and 75 mph winds would all be threats.

Broad upper level ridging gives way to weak northwest flow aloft by
Tuesday. Overall this will not bring any big changes to temperatures
and humidity, but both should drop a bit, especially in southwest
MN. By Wednesday and Thursday upper level ridging builds across the
southern and central Rockies leaving the immediate area within this
weaker west to northwest flow aloft. Models do have some marginal
agreement that the ridge will break down Wednesday into Thursday so
maybe a slightly better chance for showers and thunderstorms as we
get into late next week but way too early to say just yet.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1206 PM CDT Thu Aug 14 2025

Southerly winds will gust to 25 to 30 mph at times today, then
diminish to more of a steady 10 to 15 mph tonight into Friday.
Overall VFR conditions are expected through the period. Some
spotty showers and isolated thunderstorms will be possible later
tonight into Friday morning but confidence is very low on
development.
