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.
