KEY MESSAGES

- Precipitation chances linger into Tuesday.

- Cooler, fall-like temperatures expected midweek and through the weekend.

DISCUSSION

Issued at 300 PM CST Mon Nov 2 2026

Early this morning, dense cloud cover cloaked the region with strong southerly surface and low-level flow. While these conditions are not necessarily reflections of more recent observations (notably the thinning of cloud cover in the southern portions of our forecast area), they symbolize the challenges of the short-term forecast which has been marked by hindrances and catalysts alike. Water vapor imagery around 2 PM shows the base of the mid-level shortwave has made it to the Texas/Oklahoma panhandle with a surface cold front/dryline sitting just to the east. East of this boundary, in what can be considered the warm sector, strong southerly flow has pushed dewpoints into the low/mid 60s and temperatures into the low/mid 70s. Convective initiation has begun in western and central Oklahoma. ACARS soundings out of KMCI showcase much weaker instability than what has been noted over Oklahoma. A few showers and storms storms have been able develop in the far western portions of our forecast area this afternoon by taking advantage of a strong mid-level jet and weak elevated instability but remain shallow given the poor buoyancy. Continued destabilization throughout the afternoon could present an isolated severe threat, but the greater severe threat is still expected to arrive later in the evening. Close monitoring of the environment in the extreme near term (next 1-2 hours or so) will be necessary.

Late this afternoon and evening, storms are expected to develop along the dryline in portions of Texas and Oklahoma before racing northeastward with the mid-level jet. Over time, these storms are expected to grow upscale into a linear/QLCS mode. With such a powerful mid-level jet, storm motions of 50-60 knots are probable, enhancing the typical linear storm mode wind threat. MUCAPE is also expected to peak around 500-750 J/kg late this evening with CAMs suggesting 3CAPE ~50 J/kg. Cyclonically curved hodographs are also progged to elongate over the course of the evening with the HREF 10th percentile 0-1km SRH exceeding 300 m2/s2 (mean 0-1km SRH ~350 m2/s2). Needless to say, the forecast environment is certainly capable of mesovortex generation; as such, there is an elevated threat of brief line-embedded tornadoes this evening. Anomalously high PWATs around 1.75" could introduce some minor flooding concerns. Given the progressive nature of the incoming system, flash flooding concerns will likely be highly localized and limited to areas that experience especially heavy downpours in a very short amount of time...total accumulations by Tuesday evening are expected to be between 1.0-1.5" with locally higher amounts possible. Generally lesser accumulations are expected in far northwest and central Missouri near US-63.

The line of storms will continue to progress eastward with a diminishing severe threat overnight. Early Tuesday morning, a brief restrengthening is possible in the eastern portions of the forecast area, generally in the vicinity of the US-63 corridor ahead of the cold front. Instability during this time looks especially weak, however, and with exceptionally strong deep-layer shear (on the order of 60-70 kts), it is hard to imagine that many (if any) updrafts will survive long enough to become strong or severe before being sheared apart. Elsewhere, there may be some lingering scattered post-frontal showers/storms throughout the day.

Much cooler, more seasonal temperatures are expected for the latter half of the week with daily highs in the upper 50s to lower 60s through the weekend. Some guidance suggests potential another system to move through Sunday into Monday while others do not, so trends will need to be followed over the coming days.

AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/

Issued at 521 PM CST Mon Nov 2 2026

Bands of shower and thunderstorms are expected to race northeast across the region tonight in rapid flow aloft. Visibility may be temporarily lowered in stronger storms, along with the potential for gusty winds. Cold front is expected to lag with this system, potentially not working through the region until Tuesday afternoon. Ceilings are largely expected to remain in the MVFR category through much of the forecast period.
