From the 12:10 a.m. discussion

Storms this afternoon/evening, severe Slight Risk most areas. Extreme Heat Warning ends 8 PM tonight south of US-36, 8 PM Tuesday around KC Metro.

From the NWS discussion issued 12:10 a.m. Mon Sep 7.

The forecast

  • Monday afternoon and evening (whole area; severe risk for most of the area): A 30-50% chance of showers and storms. Some could be severe across most of the area, with damaging wind gusts, hail and locally heavy rain.
  • Monday (Northern Missouri; between US-36 and I-70; south of I-70 and near the MO/KS border): Hot. Highs in the upper 80s and low 90s in northern Missouri, low/mid 90s between US-36 and I-70, and mid/upper 90s south of I-70 and near the Missouri/Kansas border.
  • Tuesday (Kansas City Metro and south; central Missouri): Hazardous heat continues; Extreme Heat Warning until 8 PM for the Kansas City Metro and south, with 105F heat index values. Central Missouri may also need a heat alert Tuesday, depending on the cold front's still-unclear timing.
  • Tuesday night into Wednesday: A cold front is most likely to pass overnight Tuesday into early Wednesday, though its timing is unclear. Rain and storm chances on Wednesday.
  • Thursday (Northern Missouri and northeastern Kansas; around and south of I-70): Widespread relief from the heat. Highs in the low/mid 80s in northern Missouri and northeastern Kansas, mid/upper 80s around and south of I-70. More rain and storm chances.
  • This weekend: More rain and storm chances. Some organized storms are possible, but forecasters say too many details are still unsettled.

How sure forecasters were

Forecasters have high confidence the heat-producing pattern breaks down over several days, gone by Wednesday. The cold front's timing is unclear, and storm details for later in the week and weekend are not settled.

Why the forecast might change

  • If the cold front arrives overnight Tuesday as expected, a heat alert Wednesday is probably not needed, but one may still be needed Tuesday in central Missouri. A different front timing could change this. (central Missouri)
  • How strong storms get Wednesday, Thursday and the weekend is still uncertain.

Where the NWS text was unclear

  • The summary says a Slight Risk (Level 2 of 5) of severe storms, but the longer discussion, written Sunday afternoon, mentions a Marginal Risk (Level 1 of 5). The summary is newer.
  • The longer discussion was written Sunday afternoon, so its "today" and "tonight" storm and heavy-rain details (including a heavy-rain risk in northwestern Missouri) may refer to Sunday, not Monday.
  • The summary says the warning runs until 8 PM tonight south of US-36, but the official list only shows warnings until 8 PM Tuesday.

The numbers then

Not recorded: wxexplained began keeping the NWS forecast numbers on November 6, 2026.

From the 3:52 a.m. discussion

Extreme Heat Warning for the Kansas City Metro and nearby counties through 8 PM Tuesday; heat peaks Tuesday, storms Wednesday, relief areawide by Thursday.

From the NWS discussion issued 3:52 a.m. Mon Sep 7.

The forecast

  • Today (Monday): A few leftover showers and weaker storms early this morning should drift southeast and fade. Temperatures should be a couple to a few degrees cooler than Sunday.
  • Tuesday: Heat surges back and peaks, with highs likely in the mid 90s to 100 across the area.
  • Wednesday (Northern Missouri; south of Highway 36; some southern areas): Showers and storms are expected as a cold front drops through, but how fast it moves south is uncertain. Northern Missouri cools to the mid 80s. South of Highway 36 highs are uncertain; some southern areas could reach upper 90s to 100.
  • Thursday: Cooler air covers the whole area, with highs in the low to mid 80s.
  • Friday through next Tuesday: More chances for showers and storms come and go. At this point, those chances appear to be Friday/Saturday and again Monday/Tuesday.

How sure forecasters were

Forecasters say Tuesday's heat is likely. Some uncertainty remains in how fast Wednesday's cold front moves south, which affects temperatures south of Highway 36. The severe storm threat appears fairly muted.

What to watch

Extreme Heat Warning

Through 8 PM Tuesday (Kansas City Metro and immediately surrounding counties)

An Extreme Heat Warning, an official alert for hazardous heat, is in effect through 8 PM Tuesday for the Kansas City Metro and immediately surrounding counties.

Possible additional heat alert

Tuesday (Areas north, northeast and east of the warning area)

Another short-lasting heat alert may be needed Tuesday for areas north, northeast and east of the current warning as heat briefly surges back across Missouri.

Possible heat alert

Wednesday (Southern areas where the forecast range includes upper 90s to 100)

A heat alert remains possible Wednesday for southern areas where the range of forecasts includes highs of upper 90s to 100 and heat index values that would at least approach Advisory criteria.

A few strong to severe storms

Storms Wednesday; Marginal Risk outlooks for Day 2 and 3 (Tuesday and Wednesday) (Portions of the area)

Storms return Wednesday and may include a few strong to severe ones, mainly with wind, though the threat appears fairly muted. The Storm Prediction Center has Day 2 and 3 Marginal Risk outlooks for portions of the area.

  • A possible extra heat alert Tuesday is now aimed at areas north, northeast and east of the warning; before, it was for portions of central Missouri. (Areas north, northeast and east of the warning)
  • For Wednesday storms, forecasters now say the severe threat appears fairly muted, with a few strong to severe storms possible; before, they said too many details were unsettled. (Portions of the area)

The numbers then

Not recorded: wxexplained began keeping the NWS forecast numbers on November 6, 2026.

From the 2:03 p.m. discussion

Dangerous heat Tuesday for most; strong to severe storms possible Tuesday afternoon into overnight, and Wednesday afternoon mainly south. Cooler from Thursday.

From the NWS discussion issued 2:03 p.m. Mon Sep 7.

The forecast

  • Tuesday (Whole area; heat index lower in northeastern areas): Hot everywhere, with highs in the mid to upper 90s. Dangerous heat covers most of the area by afternoon. Northeastern areas may be less humid, so the heat index there may not be as high.
  • Tuesday late afternoon through overnight (Far northern and northwestern areas first, then spreading south): A strong cold front arrives late Tuesday afternoon and evening and slowly moves south overnight. Storms most likely form between 7 PM and 10 PM CDT in far northern and northwestern areas.
  • Wednesday (Southern areas; heat possibly south of the Missouri River): Heat may continue Wednesday for areas south of the Missouri River. New storms are possible Wednesday afternoon, most likely in southern areas.
  • Thursday: The cold front ends the extreme heat. Highs should be closer to normal for this time of year, and it should feel less humid, with dewpoints in the middle 60s for most Thursday afternoon.
  • Weekend through end of forecast: Temperatures warm up a bit for the weekend, but highs should stay in the middle 80s through the end of the forecast.

How sure forecasters were

Forecasters call Wednesday's heat and storms uncertain because they depend on where the front and Tuesday night's storms end up. The forecaster puts the chance of extending heat alerts into Wednesday at around 50-60%.

Speaking of fronts, a fairly robust front will be moving into the region late Tuesday afternoon and evening and slowly move south through the overnight hours.
NWS Kansas City/Pleasant Hill, Area Forecast Discussion, 2:03 p.m. Mon Sep 7
But the front will provide a focus for convective development, most likely in the 00Z [7 PM CDT] to 03Z [10 PM CDT] time frame in our far northern/ northwestern zones.

I'd put it around 50-60%. So there is a fair amount of uncertainty as a result of the front and potential for new convection along it.

Then for Wednesday afternoon, the forecast is dependent on where that front or any outflow boundaries reside.

What to watch

Extreme Heat Warning and Heat Advisory

Tuesday; warning until 8 PM CDT, advisory noon to 8 PM CDT (Warning: Kansas City Metro and immediately surrounding counties; Advisory: surrounding Missouri counties to the north, northeast and east, plus one Kansas zone)

An Extreme Heat Warning (dangerous heat) runs until 8 PM CDT Tuesday for the Kansas City Metro and nearby counties. A Heat Advisory (hazardous heat) covers surrounding Missouri counties north, northeast and east, plus one Kansas zone, noon to 8 PM CDT Tuesday.

Possible dangerous heat continuing Wednesday

Wednesday afternoon (South of the Missouri River (most likely area: along and south of the river))

Dangerous heat may continue into Wednesday south of the Missouri River. Forecasters held off extending heat alerts for now; the forecaster puts the chance of extending them at around 50-60%.

Strong to severe storms

Tuesday afternoon into overnight (Starting in far northern and northwestern areas, then moving south)

Strong to severe storms are possible. The first storms could bring downburst winds and large hail; later, as the front moves south overnight, the main threat should be wind.

Strong to severe storms

Wednesday afternoon (Most likely southern areas)

Strong to severe storms are possible again Wednesday afternoon, most likely in southern areas. Winds higher up that help organize storms may be stronger than on Tuesday.

Shear may also be stronger than Tuesday as the mid/upper level jet has shifted southward.
NWS Kansas City/Pleasant Hill, Area Forecast Discussion, 2:03 p.m. Mon Sep 7

Why the forecast might change

  • Part of the heat alerts may need extending into Wednesday afternoon; the most likely area is along and south of the Missouri River (forecaster estimate around 50-60%). It depends on Tuesday night to Wednesday morning storms and any new Wednesday afternoon storms. (Most likely along and south of the Missouri River)
  • Where Wednesday afternoon storms form depends on where the front or leftover storm boundaries end up. (Southern areas)

I'd put it around 50-60%. So there is a fair amount of uncertainty as a result of the front and potential for new convection along it.

dependent on how convection from Tuesday evening through Wednesday morning evolves and if any new convection develops Wednesday afternoon.
NWS Kansas City/Pleasant Hill, Area Forecast Discussion, 2:03 p.m. Mon Sep 7
Then for Wednesday afternoon, the forecast is dependent on where that front or any outflow boundaries reside.

Given the current headline orientation, Excessive Heat Warning for the KC Metro area counties and areas W and S through Tuesday, an additional short- duration headline may be necessary for surrounding areas to the N/NE/E.

This too keeps the notion of a possible heat headline in play Wednesday for southern areas where these wide spreads include the potential for upper 90s to 100 and heat index values that would at least approach Advisory criteria.

Where the NWS text was unclear

  • The current discussion does not say whether there are rain or storm chances after Wednesday; the earlier discussion had mentioned chances around Friday/Saturday.
  • Thursday's highs are described only as closer to normal, with normals given as "lower 80s to near 80," an unclear range; no exact Thursday highs are given.
Read the NWS wording
At this point, those chances appear to be in the Friday/Saturday and Monday/Tuesday time frames as deterministic and ensemble guidance depict shortwave troughs sliding through.
NWS Kansas City/Pleasant Hill, previous Area Forecast Discussion, 12:20 p.m. Mon Sep 7
High temperatures by Thursday should be closer to seasonal normals, which now are in the lower 80s to near 80 by the end of the week.
