KEY MESSAGES

- Storms continue early this morning with flash flooding and river flooding being the primary concerns.

- Low chance of severe storms across central Kansas with damaging winds around 60-70 mph possible.

- An active pattern continues Wednesday through the weekend.

DISCUSSION

Issued at 306 AM CDT Tue Jun 9 2026

TODAY AND TONIGHT...

Early this morning, the powerful line of storms that impacted portions of central Kansas and the Flint Hills is exiting southeast Kansas. Meanwhile, additional elevated storms have developed across central Kansas, and environment remains supportive of strong to severe storms. Much of this activity should remain along I-70.

All of this activity this morning will eventually dissipate and/or move north and east away from the forecast area. Clearing skies this afternoon along with the influence of the mid/upper ridge across the southern CONUS will allow for hot conditions to overspread much of the area. Afternoon highs will easily rise into the 90s and low 100s with heat indices between 100 and 106. Out across western Kansas, a subtle shortwave will arrive during peak diurnal heating. Just enough lift will overspread western Kansas to support very high- based showers and storms. Inverted-V model soundings suggest the primary concern will be downburst winds. While the vast majority will stay west of the area, some of it could sneak into Barton and Russell Counties towards sunset. SPC's 06Z Day 1 Outlook outlines this potential fairly well, and an enhanced risk for damaging wind gusts has been introduced and includes Great Bend and adjacent locations. With the loss of diurnal heating after sunset, much of this activity is likely to dissipate rather quickly. While extremely difficult to predict, we usually see heat bursts from this kind of set up, and gusty winds from this are also possible tonight.

WEDNESDAY THROUGH THE WEEKEND...

Hot temperatures continue on Wednesday with afternoon highs in the 90s to potentially around 100 across south-central Kansas. Humid conditions will assist in driving afternoon heat indices to around 105 across portions of south-central Kansas on Wednesday as well. A weak frontal boundary will sag into the region late Wednesday afternoon as a potent deep layer trough traverses across central/northern plains. The better synoptic lift will be located over the Upper Midwest and into the Missouri River Valley. However, there is an outside chance that convergence along the frontal boundary and ample diurnal heating could be enough to trigger a storm or two across portions of central or south-central Kansas Wednesday afternoon and evening with more numerous storms expected along and northeast of a Salina-Chanute line. Should a storm develop, the environment would support severe weather given ample instability and shear for this time of year; however storm development will be fighting some marginal subsidence from subtle height rises aloft.

With a series of deep layer troughs set to parade over the central and northern plains from the end of the work week and into the weekend, both a moderation in temperatures and an active few days are currently forecast. There are still a number of details to work out over the coming days, but the possibility of strong to severe storms does exist Thursday through Monday. Continue to monitor the forecast over the next few days.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 515 AM CDT Tue Jun 9 2026

Low clouds have started to settle into the area with most terminal sites dropping to MVFR ceilings. Ceilings should start to lift out early this morning with VFR conditions expected to prevail through this TAF period. Southerly winds will increase by late morning into the early afternoon with gusts up to 35 kts especially in central to south-central KS. There is a low chance for showers and thunderstorms late this afternoon into the evening mainly in central KS. Given the uncertainty, mention of showers and storms was left out of this issuance.
