.DISCUSSION...
Issued at 1135 PM CDT Mon Aug 31 2026
Heat continues to be the primary concern with the upper-level high
that extends from the Southern Plains into the Mississippi and Ohio
River Valleys. This pattern will remain mostly unchanged through the
week with the high moving slightly eastward Wednesday into Thursday
before moving back to the west over the Great Plains by the end of
this week. As a result, there will not be much relief from the
heat as highs remain in the mid to upper 90s and overnight lows
only drop down into the mid to upper 70s. Southerly flow into
the region will bring increasing moisture as the week goes on
supporting heat index values between 100 and 105 with the
greatest chance (15-25%) of reaching 105 on Friday afternoon for
areas south of I-70. Northern MO could see some relief from the
heat as high pressure moves back west this weekend and
shortwaves along the eastern edge of the ridge could trigger
some convection.
