Foothills of southeast Missouri. A Flood Watch remains in
effect from this through 1 PM this afternoon as 1 to 2 inches
of rain, with locally higher amounts, is expected with
additional rounds of storms.

.DISCUSSION...
Issued at 353 AM CDT Sun Jun 9 2024
At this time, showers are making their way into Southeast
Missouri. Stronger storms are located northwest towards Kansas.
A few showers are also forming in Southern Illinois where MLCAPE
of 500+ J/kg remains. Rainfall rates are lower than the earlier
storms, and severe weather potential has diminished. Northerly
winds are providing convergent surface flow towards the
boundary, fueling the rain potential.
CAMs indicate that showers and storms will continue through the
day today, with the better heavy rain and thunderstorms more
likely to occur during the morning hours. The Flood Watch was
trimmed on the eastern side leaving the western six counties of
SEMO which may receive 1-2 inches of additional rain with
locally higher amounts. CAMs are in fairly strong agreement on
8z-onward totals. PWs around 2 inches through the early
morning are at or above the 99th percentile, so heavy rates
have potential to be the driver of flooding issues rather than
just total rainfall. Model soundings suggest enough shear and
CAPE for a few strong storms and a severe storm is possible. A
marginal risk of severe weather covers much of SEMO and part of
far Western Kentucky.
Dry weather is expected for the week ahead. Initially,
temperatures will be cooler than normal with highs in the upper
half of the 70s to lower 80s Monday as northerly flow brings in
cooler air as a mid-level trough digs into the Midwest. As this
trough slides to the east, high pressure moves in on Tuesday.
With high pressure shifting to the east, light southerly flow
brings in warmer and moister air, with temperatures rising to
the lower 90s late week. The latest NBM removed the pockets of
slight chance PoPs late week. While a few ensemble members and
deterministic runs include precip chances, such as the GFS
Thursday evening, broad model support is lacking to justify
deviating from the NBM for now.

Showers with isolated lightning continue to move through
Southeast Missouri and nearby areas with the stronger storms
exiting the region. MVFR cigs will move from north to south
during the overnight hours through tomorrow morning. Additional
showers and storms move in from the west tonight, continuing
through tomorrow. The best chance for thunderstorms and heavy
rain is in Southeast Missouri and far Western Kentucky.
