.DISCUSSION...
Issued at 337 AM CDT Fri Sep 12 2025
H5 analysis overlaid with water vapor imagery shows a 593 dam H5
high centered over Texas, with relatively high amplitude upper
ridging extending northward through the Northern Plains and
Upper Midwest with upper troughing across portions of the
eastern CONUS. Meanwhile, 925 mb analysis shows a 45+ knot SSW
oriented LLJ extending from western OK up through Fargo ND. A
few isolated elevated showers are ongoing across portions of
east central Kansas along with one rogue shower near Cameron as
of 330 AM. Otherwise, temperatures range from the mid 60s to
lower 70s under generally clear skies with nearly calm winds.
As we head into this afternoon, the upper ridge axis shifts
further east, essentially directly overhead our CWA. This will
yield mid level height rises as well as increased southerly
flow, with afternoon highs rising into the mid 90s for most
locations, with SSW winds gusting up to 20 to 25 mph this
afternoon. The upper ridge axis continues to slowly migrate
further eastward through Saturday and Sunday as the easterly
trough moves northeast and another trough impinges from the
west. This will focus the hottest temperatures primarily just
east of our CWA, but Saturday is likely to feature highs in the
mid 90s for most locations, with highs in the lower 90s to mid
90s for Sunday afternoon.
By Sunday night, the western trough is progged to pivot into
the Dakotas into Nebraska, potentially taking on a slight
negative tilt. Our CWA will be southeast of the better
dynamics, but a few showers and thunderstorms may be possible
overnight Sunday into Monday morning, primarily across NE Kansas
and far NW Missouri. For early to middle of next week, a ~590
dam H5 high is projected to remain over Texas, with SW mid
level flow and pseudo upper ridging extending from Texas toward
the Great Lakes between a mid/upper low across Montana into
Canadian Plains and a closed mid/upper low over Georgia and
South Carolina. Above normal temperatures are expected to
continue, with the NBM 25th and 75th percentiles showing very
narrow goalposts (at MCI, 89 to 91 degrees for 25th and 75th
percentile MaxT for Monday and 88 to 91 degrees for Tuesday
MaxT). Mid 90s will continue to be possible toward the northern
Ozark Plateau and mid Missouri. Dry conditions are likely to
persist, with only slight chance PoPs and very low QPF on
Wednesday and Thursday. The latest drought monitor continues to
show D0 (abnormally dry) across most of our CWA, with D1
(moderate drought) creeping close to our CWA boundaries in mid
Missouri. Drought development will be something to keep an eye
on as we head toward October and the fall fire weather season.
