From the discussion of 2:52 p.m. Tue Sep 22, current when the day began

Mild, seasonable fall week: clouds and spotty drizzle today, clearing Wednesday, 30-50% shower chances Friday through the weekend, then warming to the low-to-mid 80s early next week.

From the NWS discussion issued 2:52 p.m. Tue Sep 22.

The forecast

  • This afternoon (Tuesday): Highs in the upper 60s and lower 70s. Mostly cloudy with a few peeks of sun. Pockets of drizzle or light rain continue through the afternoon, slowly moving east.
  • Wednesday through Thursday: Skies clear during the day Wednesday. Highs in the low-to-mid 70s and comfortable humidity make for a pleasant fall day. This pattern lasts through the end of the week.
  • Through Thursday (North and west of the area): Showers are expected to stay north and west of the area through Thursday.
  • Friday (whole area, northwest to southeast): Showers move into the area during Friday, spreading from northwest to southeast. Chance of rain is 30-50%.
  • This weekend: More rounds of showers, with a 30-50% chance. Thunder may be hard to come by.
  • Early next week: Warmer weather is likely to return, with temperatures climbing back into the low-to-mid 80s.

How sure forecasters were

Forecasters say computer models are in fairly good agreement on the warm-up early next week. The latest hazardous weather outlook rates the chance of widespread hazardous weather as low.

Long range deterministic and ensemble models are in fairly good agreement for mid-level ridging to build back into the Central CONUS by early next week. This would likely allow temperatures to climb back into the low-to-mid 80s.

What to watch

The NWS discussion didn't flag anything.

Why the forecast might change

  • The weekend showers have little energy for storms, so thunder may be hard to come by.

What changed from the discussion before

  • Rain now looks to hold off until Friday. Showers should stay north and west of the area through Thursday. Earlier, rain was expected to start late Thursday, with a 15-30% chance Thursday night in northwest Missouri. (whole area; earlier wording named northwest Missouri for Thursday night)
  • Friday's rain chance is now 30-50% across the area. Earlier it was 50-60% Friday morning for northwest Missouri and 30-50% for the rest of the area. (whole area; earlier wording named northwest Missouri)
  • Weekend thunder now looks less likely. Earlier, some rumbles of thunder were possible Saturday night on the western edge of the area. (whole area; earlier wording named the western edge of the area)
  • Early next week now calls for highs in the low-to-mid 80s. Earlier there was a 70-80% chance of highs above 85, especially south of I-70. (whole area; earlier wording singled out south of I-70)
  • Today's clouds and drizzle are lasting longer than expected. Clearing is now expected Wednesday instead of Tuesday afternoon.

The numbers then

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

From the 3:44 a.m. discussion

Nice fall weather with highs in the 70s for now; rain chances return Friday north of I-70, best Saturday west of I-35.

From the NWS discussion issued 3:44 a.m. Wed Sep 23.

The forecast

  • Wednesday: Another nice fall day, with highs in the 70s and mostly clear skies.
  • At least one more day after Wednesday: Staying dry for at least one more day, with temperatures in the mid to upper 70s as clouds build in ahead of rain to the west.
  • Thursday night into Friday (North of I-70, best chances in the northwest): Rain chances increase starting Thursday night. On Friday, areas north of I-70 have about a 30-50% chance of rain, with the best chances in the northwest.
  • Saturday (West of I-35; south of a Kirksville-to-Butler line): Rain chances increase through the day. West of I-35 has the best chance (60-70%); areas south of a line from Kirksville to Butler have lower chances (15-30%).
  • Sunday: Rain could potentially stick around through Sunday. Severe weather is of little concern and thunder chances are minimal this weekend.
  • Monday: Models bring drier weather back by Monday, which would end the rain, but the stalled pattern may last longer than models suggest and keep rain around longer.
  • After the stalled pattern breaks down (no day given) (whole area; southernmost counties for 90s): If the stalled pattern breaks down by Monday, highs could return to the mid 80s, with a 45-60% chance the southernmost counties see highs above 90 degrees.

How sure forecasters were

The discussion doesn't give an overall confidence level. It says rain will 'potentially' last through Sunday, and that the stuck weather pattern may last longer than computer models suggest.

NWS Kansas City/Pleasant Hill, Area Forecast Discussion, 3:44 a.m. Wed Sep 23

What to watch

The NWS discussion didn't flag anything.

Why the forecast might change

  • The stalled weather pattern bringing the weekend rain may last longer than models suggest, which could keep rain around longer.
  • The warm-up into the mid 80s, and chance of highs above 90 in the southernmost counties, depends on that pattern weakening by Monday. (whole area; southernmost counties)

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

From the 3:21 p.m. discussion

Rain chances return Friday, best in northwestern counties, reaching the whole area Saturday; heavy downpours possible. Rain expected to diminish Sunday afternoon and night.

From the NWS discussion issued 3:21 p.m. Wed Sep 23.

The forecast

  • Today (Wednesday): Pleasant fall weather with clearing clouds and more sunshine. Highs in the mid to upper 70s for most.
  • Thursday: Cooler, drier east winds keep pleasant fall conditions around through Friday, with highs around seasonal normals.
  • Friday (Mainly the northwestern counties; rain chances reach the entire area on Saturday): Rain chances start Friday morning, with the highest likelihood and amounts in the northwestern counties.
  • Friday and the weekend (Whole area; mid 80s to the south, mid to upper 60s to the north): A sharp temperature contrast sets up: mid 80s to the south and mid to upper 60s to the north. Very moist air means heavy downpours will be possible.
  • Saturday: Rain chances spread across the entire area through all of Saturday, in what forecasters call a cloudy, rainy and gloomy weekend.
  • Sunday: Rain and clouds are expected to taper off Sunday afternoon through Sunday night as the system moves on.
  • Monday: The storm system moves out. Temperatures are uncertain: near normal if the blocking weather pattern holds, or up into the mid 80s if it weakens.
  • Tuesday: Another system from the Pacific coast would bring increased chances of rain and cooler temperatures.

How sure forecasters were

Forecasters call Monday's temperatures uncertain. Computer models have been leaning toward the blocking pattern breaking down, which would allow another system Tuesday.

What to watch

Heavy downpours

Friday and the weekend, until rain diminishes Sunday afternoon through Sunday night

Very moist air means heavy downpours are possible. Clouds and near-normal temperatures limit the chance of severe weather. The outlook says widespread hazardous weather is unlikely.

Where the NWS text was unclear

  • The new discussion gives no rain-chance percentages. The earlier discussion and the latest Hazardous Weather Outlook gave 30-50% for Friday and 50-70% through the weekend; it's not clear whether those still apply.
  • The weekend temperature contrast says "to our south" and "to our north". It doesn't say whether that means parts of the area or places beyond it.
