From the discussion of 3:14 p.m. Fri Sep 11, current when the day began

Saturday late afternoon into night: storms could be severe with large hail, damaging winds, possible localized flooding. Heavy rain possible next week; placement uncertain.

From the NWS discussion issued 3:14 p.m. Fri Sep 11.

The forecast

  • Saturday morning (Western part of the area): A cold front moves in. In the western part of the area, a few showers and storms may be possible along and ahead of it (20-30%).
  • Saturday late afternoon and evening: Another round of showers and thunderstorms is expected, focused along a front that stalls across the area. Some storms could be strong to severe. Highs in the 80s.
  • Saturday night: Chances for stronger storms continue overnight, along with the potential for heavy rain. Localized flooding cannot be ruled out.
  • Sunday (Northern Missouri / northern part of the area; southern part of the area): Storm chances continue, with storms more likely in the northern part of the area. Highs in the mid 70s over northern Missouri, but reaching the upper 80s in the southern part of the area.
  • Sunday night into Monday: Drying out as high pressure builds, with highs rising into the mid 80s to mid 90s.
  • Tuesday through Thursday: Several disturbances look to set up a very wet and unsettled middle of the work week.

How sure forecasters were

Forecasters expect Saturday's late afternoon and evening storms. For next week, they say there is considerable uncertainty in where the heavy rain sets up.

What to watch

Severe storms

Saturday late afternoon into the overnight hours

There is a Marginal Risk for severe storms, the lowest level of severe risk, meaning isolated severe storms are possible. Large hail and damaging winds are the main threats.

Heavy rain and localized flooding

Saturday night into Sunday (Whole area Saturday night; mainly the northern part of the area Sunday)

Heavy rain could lead to localized flooding Saturday night. On Sunday the flooding potential continues, particularly in the northern part of the area.

Heavy rainfall next week

Next week (Whole area (placement uncertain))

An active pattern may bring multiple chances for showers and storms, with potential for heavy rainfall.

Why the forecast might change

  • Where next week's heavy rain falls depends on how strong a high-pressure ridge to the southeast is.
  • Sunday's highs depend on clouds and storms: they keep northern Missouri in the mid 70s while the southern part of the area reaches the upper 80s. (Northern Missouri and the southern part of the area)

From the 1:49 a.m. discussion

Uncertain storm chances today; repeated storms and heavy rain possible in northern Missouri next week, low to mid 90s possible south of the Missouri River.

From the NWS discussion issued 1:49 a.m. Sat Sep 12.

The forecast

  • This morning (Saturday) (Western to southwestern parts of the area): A 15-30% chance of showers or storms in western to southwestern parts of the area this morning. A storm cluster in Nebraska is expected to weaken as it moves southeast.
  • This afternoon and evening (Saturday): Just a 15-20% chance of storms. A front moves south through the area and storms may form near it, but there may be little or no activity at all.
  • Late this evening and overnight (Saturday night) (Eastern Kansas and western Missouri): Storm chances increase to 30-40% across eastern Kansas and western Missouri overnight.
  • Sunday through the end of next week (Northern Missouri): A stalled front over northern Missouri and southern Iowa could bring multiple rounds of showers and storms to northern Missouri, with widespread 2-5" of rain possible in total.
  • Next week (Roughly the Missouri River southward): From roughly the Missouri River southward, highs in the low to mid 90s are possible, potentially 10-15 degrees above normal (normal is now near 80 degrees).

How sure forecasters were

Forecasters call today's storm forecast very complex and uncertain, with considerable uncertainty on timing and location. For next week, heavy rain looks possible particularly for northern Missouri, and well above normal temperatures look likely generally south of the Missouri River.

What to watch

Strong to severe storms

Today (Saturday), especially afternoon/evening

Strong to severe storms are possible today, but only if storms actually form. If they do, some could be organized with a damaging wind and large hail risk. Timing and location are very uncertain.

Heavy rain from repeated storms

Sunday through the end of next week (Northern Missouri)

Numerous rounds of showers and storms, particularly in northern Missouri, could add up to widespread heavy rain, 2-5" possible.

Why the forecast might change

  • Today in eastern Kansas and western Missouri, a strong lid on the atmosphere may keep storms from forming at all, or enough instability above the surface may still let storms develop. (Eastern Kansas and western Missouri)
  • Next week's highs from roughly the Missouri River southward may be lower if clouds spread farther south. A stronger high-pressure ridge could push the heavy rain farther north, making it warmer than forecast. (Roughly the Missouri River southward)

Additionally, stronger ridging could shift the heavier rain further north leading to warmer temperatures than currently forecast.
NWS Kansas City/Pleasant Hill, Area Forecast Discussion, 1:49 a.m. Sat Sep 12

What changed from the discussion before

  • Saturday's storm threat is now described as much more uncertain. The previous discussion gave a Marginal Risk (low-end risk) for severe storms late afternoon into overnight; now timing and location are very uncertain and severe storms depend on storms forming.
  • Next week's heavy rain was previously very uncertain in placement; now it is focused on northern Missouri, with widespread 2-5" possible. (Northern Missouri)
  • The previous discussion said localized flooding could not be ruled out Saturday night; the current discussion does not mention flooding.

From the 2:01 p.m. discussion

Storms possible this afternoon through Sunday morning in eastern Kansas and western Missouri, with hail, damaging winds and localized flooding; heavy rain possible next week, especially northern Missouri.

From the NWS discussion issued 2:01 p.m. Sat Sep 12.

The forecast

  • This afternoon through Sunday morning (Eastern Kansas and western Missouri): Storms may form this afternoon or evening. In eastern Kansas and western Missouri, strong to isolated severe storms could bring hail up to ping pong ball size and winds to 60 mph. After a brief evening lull, storms may increase around midnight and last into Sunday morning.
  • Sunday afternoon (Whole area; showers in the eastern part): Mostly dry, though a few scattered showers (20-30%) may linger in the eastern part of the area. Highs from the lower 70s in the north to mid 80s in the south.
  • Sunday night: More showers and thunderstorms across the area. Chances of severe storms look low for now, but heavy rain may again be possible.
  • Monday (Whole area; heat index in the southern part): Showers may linger Monday morning, then a very warm day with temperatures in the mid 80s to mid 90s. In the southern part of the area, the heat index may rise to 100-105.
  • Tuesday (Whole area; heat generally south of the Missouri River): A weak cold front moves into the area. Well above normal temperatures look likely, with highs in the low to mid 90s and heat index 100-105 generally south of the Missouri River.
  • Through the middle of next week (Whole area; heaviest rain in northern Missouri): Computer models show unsettled weather with rounds of showers and storms. Several rounds are expected to bring 2-4 inches of rain to northern Missouri. Severe storm chances look low for now.
  • Late next week: The stuck weather pattern breaks down, but a passing upper-level system would keep the weather unsettled.

How sure forecasters were

Forecasters call tonight a tricky forecast after this morning's storms, and computer models differ on the timing and strength of the disturbance that may set off storms. Severe chances for Sunday night and next week look low at this time.

What to watch

Strong to severe storms with large hail and damaging winds

Tonight into Sunday morning (Eastern Kansas and western Missouri)

Storms in eastern Kansas and western Missouri could bring hail up to ping pong ball size and winds to 60 mph.

Localized flooding from heavy rain

Tonight, and again Sunday night (Eastern Kansas and western Missouri tonight; whole area Sunday night)

Storms tonight in eastern Kansas and western Missouri will drop rain efficiently; if storms repeat over the same spots, localized flooding is a concern. Heavy rain Sunday night may add flooding concerns.

Flooding from repeated heavy rain

Next week (Northern Missouri)

Several rounds of storms are expected to bring 2-4 inches of rain to northern Missouri, which may lead to flooding concerns.

Heat

Monday and Tuesday (Generally south of the Missouri River)

Well above normal temperatures look likely generally south of the Missouri River, with highs in the low to mid 90s and heat index values in the 100-105 range.

Why the forecast might change

  • Where storms form tonight is uncertain: the best chance for organized severe storms is along a boundary left by morning storms, now south of the area, but the front crossing the area may also set off storms.
  • Storms may weaken briefly this evening, then grow in number and perhaps strength around midnight as stronger winds from the southwest arrive just above the ground.

Where the NWS text was unclear

  • The key message says tonight's main threats are "large and damaging winds," which appears to be missing a word; the detailed discussion names large hail and damaging winds.
  • For Monday, the discussion gives temperatures in the mid 80s to mid 90s, while the key message says highs in the low to mid 90s generally south of the Missouri River.

The numbers then

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

From the 2:01 p.m. discussion

Strong to severe storms possible tonight, eastern Kansas/western Missouri; heat likely Monday–Tuesday generally south of Missouri River; heavy rain possible next week, particularly northern Missouri.

From the NWS discussion issued 2:01 p.m. Sat Sep 12.

The forecast

  • Tonight into Sunday morning (Eastern Kansas and western Missouri): Storms are possible tonight in eastern Kansas and western Missouri. After a brief weakening, they are expected to grow in number, and perhaps strength, around midnight, then continue overnight into Sunday morning.
  • Sunday afternoon (Whole area; showers in the eastern part of the area): Mostly dry, though a few scattered showers (20-30%) may linger in the eastern part of the area. Highs from the lower 70s in the north to mid 80s in the south.
  • Sunday night: More showers and thunderstorms across the area. The chance of severe storms looks low for now, but heavy rain may again be possible.
  • Monday (Whole area; heat index in the southern part of the area): Showers may linger Monday morning, then a very warm day with temperatures in the mid 80s to mid 90s. Heat index 100-105 in the southern part of the area.
  • Tuesday (Whole area; heat generally south of the Missouri River): A weak cold front moves into the area. Well above normal temperatures look likely, with highs in the low to mid 90s and heat index 100-105, generally south of the Missouri River.
  • Through the middle of next week (Whole area; heaviest rain in northern Missouri): Unsettled, with rounds of showers and thunderstorms. Severe chances look low for now, but several rounds are expected to bring 2-4 inches of rain to northern Missouri.
  • Late next week: The stuck weather pattern breaks down, but a passing upper-level system would keep the weather unsettled.

How sure forecasters were

Forecasters call tonight's storm setup tricky after this morning's storms, and computer models differ on the timing and strength of the system expected to trigger them.

What to watch

Strong to severe storms

Tonight (Eastern Kansas and western Missouri)

Strong to isolated severe storms are possible in eastern Kansas and western Missouri, capable of hail up to ping pong ball size and gusty to damaging winds to 60mph.

Heavy rain and localized flooding

Tonight, and again Sunday night (Tonight: eastern Kansas and western Missouri; Sunday night: whole area)

Storms tonight will be very efficient rain producers; if storms even briefly repeat over the same spots, localized flooding would be a concern. Sunday night, heavy rain may again be possible, which may bring more flooding concerns.

Heavy rain and flooding concerns

Next week (Northern Missouri)

Several rounds of storms are expected to bring 2-4 inches of rain to northern Missouri, which may lead to flooding concerns.

Heat

Monday and Tuesday (Generally south of the Missouri River)

Well above normal temperatures look likely, with highs in the low to mid 90s and heat index 100-105, generally south of the Missouri River.

Where the NWS text was unclear

  • The discussion says the best chance for organized severe storms is along a boundary that has pushed south of the area, while the key message places severe storms tonight in eastern Kansas and western Missouri.
  • The latest Hazardous Weather Outlook, issued earlier this morning, still says a low probability of widespread hazardous weather through tonight, which doesn't match the newer storm message.
