KEY MESSAGES

- An Extreme Heat Warning is in effect today through Friday.

DISCUSSION

Issued at 141 AM CDT Sun Jun 28 2026

A prolonged period of hot and humid conditions begins today as ridging over the southeast CONUS expands north and west. Gusty south winds and mixing to 850mb, where temperatures are progged to be 22-28 degrees C, will lead to highs ranging from near 100 degrees in north central Kansas to the low 90s in far eastern Kansas. Dewpoints in the upper 60s across north central Kansas and in the upper 70s across eastern Kansas will create heat index values of 104-110 degrees this afternoon. Little change to the synoptic pattern takes place through at least Friday; small spreads in temperatures from ensembles lead to high confidence in continued hot and humid conditions. Temperatures may be muted slightly Tuesday and Wednesday as a couple of shortwaves lifting northeast along the western periphery of the ridge could lead to clouds or even some showers/storms across north central Kansas. While heat indices may only reach around 100 degrees in some areas these days, hotter temperatures are expected to return Thursday and Friday and lead to more widespread heat index values of 105-110 degrees. Thus, the prolonged period of hot and humid conditions along with little overnight relief increases the risk for heat-related impacts. The Extreme Heat Warning remains in effect area-wide through Friday. There is still a signal for at least some reprieve to come this weekend as a shortwave tries to dampen the mid-level ridge and increases cloud cover and chances for precipitation.
