From the discussion of 1:55 p.m. Wed Oct 28, current when the day began

Isolated to scattered showers and storms this evening in northern Missouri and northeast Kansas, small hail possible; more rain chances through the weekend.

From the NWS discussion issued 1:55 p.m. Wed Oct 28.

The forecast

  • This evening and overnight (Northern Missouri and northeast Kansas): Isolated to scattered showers and storms this evening in northern Missouri and northeast Kansas, becoming fewer overnight.
  • Thursday (North and south of a stalled front across the area; Missouri River; northwestern Missouri): A stalled front splits the area: north of it, 60s to lower 70s; south of it, near 80 F. A 15-20% chance of a late-day shower or storm near the Missouri River; scattered showers could develop in northwestern Missouri.
  • Thursday night into Friday (Northeast Kansas to northwest and northern Missouri): A 30-75% chance of showers and thunderstorms from northeast Kansas to northwest and northern Missouri.
  • Friday night into Saturday (Halloween): More widespread showers and thunderstorms Friday night into Saturday. Halloween looks gloomy and cooler with scattered showers. Moisture in the air near the daily max (precipitable water 1.1-1.2") should make rain fall fairly efficiently.
  • Saturday and Sunday: A 30-60% chance of showers and thunderstorms across the area.
  • Friday through Wednesday; late this weekend into next week: Temperatures stay above normal for the next week but trend back closer to normal, with multiple rain chances, Friday–Wednesday. A slow-moving storm may set up late this weekend through at least the first half of next week, possibly cooler and wet.

How sure forecasters were

The discussion doesn't say how confident forecasters are overall; it uses hedges like "may", "could" and "potentially" for tonight's hail, Thursday's storms and next week's wet pattern.

Small hail

This evening (Northern Missouri and northeast Kansas)

The strongest storms this evening in northern Missouri and northeast Kansas may produce small hail.

Why the forecast might change

  • Whether Thursday's late-day shower or storm forms depends on whether winds come together enough along the front; the setup limits any severe potential. (Along the stalled front)
  • Next week's cooler, wet pattern depends on whether the incoming systems develop into a slow-moving storm over the central US.

What changed from the discussion before

  • Small hail is now mentioned with the strongest storms this evening in northern Missouri and northeast Kansas; earlier, little more than showers and a few rumbles of thunder were expected. (Northern Missouri and northeast Kansas)
  • Temperatures: earlier, above to well above normal through the forecast. Now, above normal for the next week but trending back closer to normal Friday through Wednesday.
  • Thursday afternoon's 15-20% chance is now described as near the Missouri River instead of south of it. (Missouri River area)
  • Thursday highs: north now 60s to lower 70s (was lower 70s); south now near 80 F (was closer to the low 80s south of the Missouri River). (North and south parts of the area)

Where the NWS text was unclear

  • Thursday's storm chance is placed "near Missouri River" in the key messages, but the discussion says it would form along the stalled front without saying exactly where that front sits.
  • The latest Hazardous Weather Outlook was issued earlier and still repeats the older key messages, which differ from the current discussion.

Discussion

The current cold front situated just NW of MO will continue to sag
southward before becoming quasi-stationary over northern/central MO
by the afternoon tomorrow. Despite earlier convection along the cold
front, an increasingly inhibited environment with an unfavorable
synoptic environment has decreased PoPs through the overnight. High
temperatures behind the front fall to the high 60s/low 70s,
while areas south of the front remain around the 80s. Continued
spread in HREF members on temperature solutions during the
afternoon (~4-6 degF spreads) remains across the northern half
of MO. However, this corridor of spread narrows through the
course of the day, increasing confidence in the position of the
front eventually settling over central MO. South of the boundary
closer to the US-50 corridor, low- level southerly flow will
create a narrow corridor of elevated instability by the late
afternoon. Capping will prevent any initiation earlier on in the
day, but guidance increasingly indicates the erosion of the cap
by the late afternoon. However, our other ingredients for
thunderstorm development (vertical wind shear and lift) remain
marginal at best, with better synoptic forcing (a shortwave, a
LLJ, etc.) remaining displaced from the boundary's location.
This creates a setup where, although convection is not out of
the question with surface convergence along the boundary by the
mid-late afternoon, the risk of severe activity remains low. By
this evening, low-level WAA out ahead of a shortwave will
reinvigorate chances for precipitation (40-60%) as the boundary
lifts back northward. Convective guidance resolves this activity
as widespread scattered showers, with building convective
inhibition as the nocturnal boundary layer establishes itself
despite increasingly favorable shear profiles and elevated
instability. This activity looks to persist through early Friday
morning/afternoon as the boundary stalls out once again over
northern MO, with overall PoPs around 15-30% through the
afternoon and evening.

A stout mid-level ridge persists over the eastern third of the
CONUS, keeping the forecast area within the periphery of its flow.
Another shortwave following the atmospheric flow northward from the
southern Plains will increase PoPs (70-90%) Friday evening,
bolstered by dCVA at the base of an oncoming mid-level trough. This
low amplitude trough will act to push the mid-level ridge axis
further off towards the east. However, persistent low-level WAA and
dCVA south of I-70 will keep PoPs around 30-50% through Saturday
afternoon/evening, which isn't great news for any folks looking to
go out for Halloween. In (slightly?) better news, surface winds out
of the E/SE coupled with increased cloud cover will help
temperatures to fall to the high 60s/low 70s areawide by Saturday,
which (although still seasonally high) is much better than continued
80 degree temperatures into November. By Sunday, PoPs look to clear
out, with semi-zonal flow as the ridge axis bends off towards the
northwest and a mid-level trough over the western CONUS begins its
trek eastward. Models continue to indicate the development of a
deepening surface cyclone over the central CONUS, which will
continue to leave the beginning of next week looking wet as the
cyclone lifts off towards the northeast. Synoptic model guidance
begins to deviate by the later part of the forecast period on the
location of the trough axis over the central CONUS, and whether the
trough closes off or continues to propagate along the
atmospheric flow. This leads to greater deviations in PoPs by
next Wednesday, which decreases overall confidence in solutions
for precipitation in the extended forecast. Greater advection of
dry, cooler air from the northwest behind the initial surface
cyclone will continue to lower temperatures into the early days
of November to the high 50s/low 60s areawide.

From the 2:30 p.m. discussion

The NWS discussion issued 2:30 p.m. Thu Oct 29

The plain version didn't pass the accuracy check (a quote or number didn't match the NWS text), so the NWS text was shown instead.

Key messages

- Scattered showers and storms possible (40-70% chance) Thursday
  night into Friday across portions of northeast Kansas and
  northern Missouri. Backbuilding storms could lead to localized
  flooding concerns.

- Additional showers and storms Friday evening through Saturday
  morning (30-50% chance south of I-70, 50-70% chance north of
  I-70). Rain chances generally decrease to about 20-30% by
  evening.

- Rainy start to next week areawide.

Discussion

What has been generally zonal flow aloft will become increasingly
meridional over the coming days, leading to a more active period for
weather. A cold front has slipped southward throughout the morning.
Latest surface observations indicate this boundary now sits near the
Missouri River with temperatures roughly 3-5 degF cooler on the
north side of front. As for high temperatures today, we could see
about a 10 degF temperature difference between our northern and
southern tiers of counties. The front is expected to continue
sinking south throughout the afternoon and evening, becoming more
diffuse in the process. Isolated shower or storm development south
of the boundary this afternoon remains possible under WAA
conditions, but it seems such development would be quite the uphill
battle given poor shear and lackluster lapse rates. The arrival of
the cold front could inspire a brief shower or storm. Even so, I
would not expect anything remotely robust given the lack of upper-
level support. Shower and storm activity appears to be more likely
(40-70%) across northeastern Kansas and northern Missouri beginning
later this evening and then continuing through the early portions of
the day on Friday. Continued low-level WAA will promote a region of
elevated instability (as much as 800 J/kg) in these areas by late
evening. Lift looks to be provided by an approaching shortwave with
several members of the guidance resolving a localized vortmax north
of the Missouri River around 06Z; roughly around this time is when
CAMs also begin to resolve scattered showers and storms. CAMs also
present a backbuilding scenario across far northeast Kansas into
northwest Missouri...with PWATs between 1.25-1.5", isolated flooding
may occur where showers/storms continuously move over the same area.

Scattered showers and storms will continue across portions of
northern Kansas and Missouri for much of the day on Friday. Further
south, the cold front currently crawling through our CWA will lift
back north as a warm front in the afternoon/evening. This with an
approaching mid-level trough will reinvigorate rain chances for much
of the region Friday PM into Saturday AM (hourly PoPs about 40-70%).
Low-end rain chances will continue for the remainder of the day as
the mid-level trough continues its journey through the
Plains/Midwest. Generally along and west of the I-35 and I-49
corridors, these chances are closer to 20-30% given a low-level dry
layer and little upper-level support from the vacating mid-level
trough. Further into central Missouri, these rain chances are
slightly higher at 30-50% where the mid-level trough may still
retain some influence.

Sunday continues to look dry with temperatures in the upper 60s/low
70s. A deepening upper trough over the western CONUS will slide to
eastward over the weekend with its accompanying surface cyclone
moving into the Great Plains on Monday. This system will result in a
more active weather pattern than what we have become accustomed to
in recent days and even some weeks. Indeed, the first half of the
week looks rather soggy (Monday and Tuesday especially).
Unsurprisingly, the entire CWA as well as a large chunk of the
Central Plains are included in a Day 5 Marginal Risk (Level 1 of 4)
for excessive rainfall on Monday, Nov. 2. We will need to monitor
potential instability corridors ahead of the  surface
low's attendant cold front as these areas would have an inherently
higher risk for flooding due to convectively-driven high rainfall
rates.
