.DISCUSSION...
Issued at 109 AM CDT Fri Aug 28 2026

As of 1 AM CDT, temperatures across the region are in the mid 50s to
low 60s with light winds generally out of the east to southeast. Low
pressure develops off the Rockies today bringing precipitation
chances all day and a chance for severe weather this evening, 40-
70%. There is a Marginal risk (level 1 out of 5) for severe weather
with these storms. Main hazards are 1 inch hail and 60-70 mph wind
gusts. PWATs over the area are in the 1.25 to 1.5 inch range which
could also result in brief heavy rainfall. CAMs are in pretty much 2
camps as to when and where the majority of the storms will take
place. The first develops in south central SD at around 7 PM CDT and
intensifies as it moves east across the southern portion of the CWA.
The second moves into the area out of ND closer to midnight CDT,
moves east and intensifies into northeast SD. Both camps have storms
out of the area by sunrise Saturday morning. There is also a Slight
risk (level 2 out of 5) for portions of north central SD and a
Marginal risk for areas west of the Prairie Coteau/Sisseton Hills
Saturday as the low moves off the Rockies. Following this, low level
precipitation chances remain in place most days as a series of low
pressure systems move across southern Canada.

Temperatures through the period remain around to slightly above
average. Some light elevated smoke will move into the area today,
resulting in hazy skies. Winds across south central SD will gust 25-
30 mph and these look to be the highest winds through the 7-day. We
could begin to see some elevated fire danger next work week if we
don`t get much rain out of these storms.
