.DISCUSSION...

Issued at 156 AM CDT Mon Jun 29 2026



An upper level ridge will continue to build across the region 

today while a surface low develops off the Rockies and ejects 

into the northern plains. Upper ridging will remain in place 

through most of the extended period with some broadening of the 

ridge towards late week and into the weekend. Today begins an 

extended period of temperatures in 90s with mid to upper 90s 

expected by Tuesday. These temperatures combined with dewpoints 

in the upper 70s results in heat indices between 105 and 115 

degrees. Little relief will be felt at night with low 

temperatures in the mid to upper 70s. The excessive heat warning

for the entire area begins at 17Z and continues into Friday. 

Convection may start to develop as early as Thursday but at this

time looks to be isolated with more scattered activity

developing over the weekend.
