DISCUSSION

Issued at 316 PM CDT Sat Jul 25 2026

The large upper-level dome of high pressure has led to relentless heat and humidity across much of the central US today and is expected to keep heat concerns through Monday. Today, afternoon temperatures in the mid to upper 90s are common as highs are expected to top out a few degrees further in the next few hours. This paired with a very oppressive and humid airmass - characterized by dewpoints in the upper 70s and low 80s - has led to heat indices in the 105-120 degree range. An Extreme heat Warning has been extended to include all of eastern Kansas and portions of central KS. The remainder of the area across north-central KS remains under a Heat Advisory.

The next few days will not see much improvement in the heat as temperatures Sunday and Monday will top out in the upper 90s to low 100s. Dewpoints Sunday/Monday are expected to mix out a bit under slightly windier conditions, but dewpoints still around 70-75 degrees, heat indices will again push into the 105-115 degree range. The first 'cool' day may come by Tuesday as energy rounding the upper ridge pushes a weak frontal boundary across the area through the morning and early afternoon. Areas across northern Kansas may see highs top out in the low 90s behind this boundary while areas across east-central and southern Kansas may still warm into the mid to upper 90s with heat indices pushing back into the low to mid 100s. Along with the frontal passage, some low-end PoPs can be expected, mainly across central and north-central KS Tuesday morning and afternoon. This could too help to keep things a bit cooler during the day Tuesday and this uncertainty in temperatures Tuesday has kept heat headlines as an Extreme Heat Watch at this time.

A slightly cooler and more seasonable summer pattern sets up Wednesday and into the weekend as temperatures fall back towards the low 90s. As the upper ridge regresses back west through the week, an increase in mid-level waves will be able to round the ridge and pass over the region. This should yield some off an on chances for PoPs near daily with Thursday into Friday looking to be the next best chance for widespread precipitation.

VFR conditions are expected. There is at least a low chance for limiting BR formation over the next several hours, mainly at KTOP, but expect mixing to be enough to keep this out of the forecast.
