DISCUSSION

Issued at 334 AM CDT Sun Aug 9 2026

Upper ridging remains situated over the Four Corners region with troughing from Ontario down into the Great Lakes region. At the surface, weak stationary front stretches from northern MO into north central KS.

Some scattered showers and a few storms have been tracking across northeast KS into parts of the Flint Hills overnight in an area of 700mb warm advection. This activity should continue to slowly slide southeast early this morning.

Another very hot day will be in place today across the entire area, with most locations seeing highs in the 100-106 range. Looking at records, the only site that will have a chance will be Russell, which has a record of 106. We should see dewpoints mix-out more today than they did on Sat which should keep heat indices from getting at or above 110 degrees. With confidence high in widespread heat indices around 105 for several hours today, went ahead and issued a heat advisory for the entire area. Front will become more defined late this afternoon and early evening from southeast NE into northwest KS and may provide the focus for a storm or two along or north of I-70 after 22z. Just like late Sat afternoon/early evening, coverage will be minimal with only a storm or two expected if they do develop.

Confidence is high that hot temps will remain in place for Mon with most locations once again in the 100 to 105 range. While there is a good chance at least part of the area will eventually be put into a heat advisory for Mon, increasing high clouds and low confidence on how much dps will mix out is keeping us from going with one at this time. Not much is expected to change for Tue, with all areas once again seeing high at or above the century mark. For both Mon and Tue, surface front will continue to linger between I-70 and the KS/NE border and may provide the focus for a storm or two. With coverage extremely minimal if storms do develop, will leave mention of storms out for now. On Wed, there remains good agreement in an upper impulse digging southeast out of southern B.C. with some additional upper energy moving into central CA. This will allow some monsoonal perturbations to track over the Central Rockies and out into the Central Plains for Wed night. This will ramp-up shower and storm chances, but it it looks like the higher chances will remain north of the forecast area. So we are looking for another very hot day on Wed with highs similar to Mon and Tue.

Broad western CONUS upper troughing will keep fairly high storm chances in for Thu-Sat, especially across Nebraska and northern portions of KS. Confidence is low on how far south precip and cooler temps will make it, as models have trended to keep the front and precip further north, which would result in continued hot temps for Thu and possibly Fri, especially for the southern portion of the forecast area.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1044 PM CDT Sat Aug 8 2026

Low level wind shear overnight into the morning hours (13-14Z) is the main concern for this forecast period west of the Kansas Turnpike. Given the more southeast to east southeast winds in some locations, the directional component switches to the southwest and the speed could reach 45-50kts at around 2k feet. Winds stay around 10-15kts overnight then will slightly increase with gusts approaching 30kts through the afternoon. Otherwise VFR conditions should prevail.
