.SHORT TERM /THROUGH TONIGHT/...
Issued at 200 PM CDT Sun Jun 8 2025

Through Tonight: Water vapor imagery depicts an upper level low
dropping south into the Upper Mississippi Valley. An associated
cold front extents southwestward through the central CONUS, and
will be the focus for shower and thunderstorm development this
afternoon. Latest surface analysis depicts the cold front across
northwest MO, where visible satellite shows growing cumulus.
Ahead of the front, low level moisture continues to lift north
into the Ozarks, with dewpoints reaching into the middle to upper
60s this afternoon. Ample sunshine and daytime heating have
given way to highs in the lower to middle 80s, further
destabilizing the airmass ahead of the front. MUCAPE values are
progged to approach 2500-3500 J/kg at its peak, with 0-6km deep
layer shear around 30 to 50 knots. Convective initiation is
expected to occur between 2 to 4 PM to the north, and gradually
slide south and east into the area. Initial storm mode is
expected to be supercells, before growing into multicell
clusters. This is supported by most of the CAMs, that also
indicate potential storm splitting (with unidirectional wind
profiles). A Slight Risk (2 out of 5) covers the entire Ozarks
area, though the best severe potential will likely be tied to
the instability axis and timing/location of the front (generally
north of Interstate 44) between 4 to 8 PM. Primary risk will be
large hail up to the size of golf balls, supported by the Large
Hail Parameter around 4 to 6. Meanwhile, steep low- level lapse
rates around 7.5 to 8.C support potential damage wind gusts.
Given the southwest surface winds, the tornado threat is very
low. Thunderstorm activity will gradually decrease in coverage
and intensity after sunset, with the front slowing into southern
MO. The slowing down of the front will open the door for
potential localized flash flooding. Soils are saturated across
the area therefore it won't take much for flooding. HREF PMM
depicts localized rainfall amounts of 1 to 2 inches across far
southeast KS and the Interstate 49 corridor. Any lingering
showers and thunderstorms will dissipate and move out of the
area into early Monday morning.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 200 PM CDT Sun Jun 8 2025

Monday-Wednesday: A few days of drier weather are expected into
early week with the upper low moving off into the Great Lakes.
The area will be in northwest flow on Monday and Tuesday, with
some mid-level height rises into Wednesday. This will support
temperatures in the upper 70s to lower 80s through Wednesday.
It appears any weak energy translating through the flow will
remain moisture starved, thus keeping the area mostly dry.

Thursday-Saturday: Ensemble cluster analysis continue to be in
good agreement on an active pattern returning late week into
next weekend. The first initial wave moves into the area on
Thursday as a warm front lifts towards the region. Scattered
shower and thunderstorm chances on Thursday (20-50%).
Increasing rain chances (40-70%) with additional waves through
the weekend. Given the saturated conditions, we will need to
monitor for the potential for flooding through next weekend.
Continue to monitor the forecast for updates.
