293 FXUS63 KEAX 291719 AFDEAX Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 1219 PM CDT Mon Jun 29 2026 .KEY MESSAGES... * Extreme Heat Warning in effect through Friday evening. Overnight lows in the mid and upper 70s will not provide much relief from daytime heat. * Most areas will dry out this week with the next widespread small chance (20-30%) for rain holding off until Independence weekend (Saturday Night/Sunday). && .DISCUSSION... Issued at 320 AM CDT Mon Jun 29 2026 Ridging will continue to build over the eastern CONUS through the week. Additionally, deep troughing will move through the Rockies and northern Plains today. This will place northwestern Missouri and northeastern Kansas between these features. At the surface and low levels, the increased pressure gradient and flow will increase sustained winds, gusts, temperatures, and dew points. Today, expect to see sustained winds around 20mph and gusts 30-35mph. Highs today are expected to be in the low and mid 90s. With dew points in the upper 70s, this puts heat indices in the 105-110 range. These hot and humid conditions will continue through the end of this week, and possibly into the weekend. Highs will continue to be in the low to mid 90s and some spots in the upper 90s. Heat indices will continue in the 100-110 range through the week. Low temperatures overnight will not provide much relief from daytime heat. Low temperatures will be in the mid and upper 70s through the week. These low temperatures are much above the 90th percentile of climatology for the region. Given hot daytime temperatures, hot overnight temperatures, and the duration of the heat this week, an Extreme Heat Warning was issued through Friday evening. This is a high confidence forecast, with much deterministic and ensemble guidance showing little spread. Along the periphery of the ridging, vorticity will move northeast. This will bring showers and storms through Nebraska. As these storms move east, they will encounter subsidence and will dissipate. In far northwestern Missouri, there is a small chance for a dissipating shower or storm each night. Beyond Friday, there is some uncertainty. Ridging may begin to broaden and shortwave energy may move over the region. This would help to reduce heating over the week and introduce a small chance for showers and storms. Though there is still possibilities that ridging persists, where heat would continue. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
