.DISCUSSION...
Issued at 158 AM CST Sun Nov 1 2026

Precipitation chances will decrease through the morning hours today
as shortwave ridging builds eastward into the area. However,
moisture will be trapped in the lower portions of the atmosphere so
we`ll continue to see cloud cover. This should keep highs in the 60s
across the area.

Focus shifts to Monday afternoon through the overnight hours as a
strong shortwave trough moves east into the central US. A surface
low will deepen across Nebraska with a front trailing southward
through Kansas. Very strong southerly low-level flow will lead to
anomalously high precipitable water values, supporting potential for
heavy rainfall. In the upper-levels, a leading jet max may help
initiate storms in the warm sector. But`s a trailing, stronger
jet max will move across the area later in the day and into the
overnight hours. And that seems to be the more likely time frame
for severe storms across eastern Kansas into western Missouri.
Storms seem likely to initiate along the cold front in central
Kansas and Oklahoma during the afternoon. These may be
supercells initially but these should develop into a line as
they move east late in the afternoon and evening, with damaging
winds being the most likely hazard. Favorable 0-3KM shear of
30-40kts may also support embedded circulations within the line
of storms. With 0-.5km helicity values pushing 200 m2/s2 can`t
rule out a tornado or two over eastern Kansas and adjacent areas
of Missouri as the line of storms moves east during the evening
and overnight hours. The Slight Risk area was expanded
northeastward on the latest Day 2 Convective Outlook, with much
of western Missouri and eastern Kansas in a Marginal Risk.

Unsettled weather will linger into Tuesday, though how unsettled it
may be is a little uncertain. The deterministic NAM is considerably
slower with the upper wave and and actually has some potential for
severe weather Tuesday morning. The GFS is further east with
potential storms east of our forecast area. With the upper low
moving over Kansas into Missouri through the day, we should still
see some potential for precipitation through the day Tuesday.

Temperatures through the remainder of the forecast look cooler,
though still slightly above normal for this time of year, with highs
generally in the low to mid 60s.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 509 AM CST Sun Nov 1 2026

Conditions are likely (>75% chance) to become MVFR to low MVFR,
with lower chance (<25% chance) for IFR ceilings. Once low MVFR
conditions settle into the area, we`ll see them prevail through
the day and into the overnight hours. Conditions may improve to
MVFR late in the forecast. Winds will be light from the
southeast initially but will increase and become gusty from the
southeast late in the forecast.
