.KEY MESSAGES...

- Showers and thunderstorms will continue across portions of the
  eastern Ozarks this afternoon into this evening, decreasing by
  sunset. Rain rates of 1-3 in/hr, localized flash flooding,
  and a strong downburst or two will be possible in the
  strongest cells.

- Additional showers and storms are expected tonight into
  Sunday morning across portions of the area, especially east of
  Highway 65. Heavy rainfall and localized flooding will be
  possible with this activity.

- Another round of showers and storms will move through the
  region Sunday night into Monday. There is a Marginal (1 of 5)
  Risk for some of these storms to become severe.

- Some mild heat relief during the middle of next week following
  the frontal passage. 15-30% chances for isolated showers and
  thunderstorms will exist in southern Missouri near the front.

.SHORT TERM /THROUGH SUNDAY/...
Issued at 300 PM CDT Sat Jun 28 2025

Showers and scattered thunderstorms continue across the eastern
Ozarks this afternoon east of Highway 65. This activity will
continue to slowly move east late this afternoon into early this
evening and should dissipated by sunset this evening. The
coverage in storms may decrease in the next few hours prior to
the showers fully ending. No severe weather is expected with
this activity as shear is weak and instability is more limited.
There is a low chance (<15%) for an isolated shower/storm along
and west of Highway 65 this afternoon but most locations should
remain dry through this evening as instability has decreased
behind the convection and lift has moved east of these
locations. The morning convection and clouds have kept the area
cool this afternoon with highs in the lower to middle 80s will
occur across much of the area. Muggy conditions will still occur
as dewpoints are in the 70s.

Tonight into Sunday morning MUCAPE will increase as the cap
weakens lift will over spread the area and additional showers
and storms are expected to develop. This activity will likely
be scattered in nature, but there is the potential for banding
of showers and storms to develop across portions of central
Missouri allowing multiple storms to track over the same
locations. Precipitable water values will be around 1.75 to 2"
leading to heavy rainfall rates with the storms. Any where
training of storms can develop heavy rainfall and a flash flood
risk will occur. These would be very localized and hard to pin
point exactly where training will exactly develop until the
convection develops. The CAMS are showing a signal for this
setting up shower were across central Missouri and the easterly
Ozarks. A quick 1 to 2" of rainfall will be possible with any
storm today, and where storms persist over the same locations
there is the potential for very localized amounts up to 4 to 6"
if training occurs over the same locations.

The convection should end by mid day on Sunday. If clouds clear
early enough in the day and instability can recover some
isolated storms would be possible late Sunday afternoon into the
evening. Coverage would not be widespread and these storms are
dependent on what occurs Sunday morning.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Issued at 300 PM CDT Sat Jun 28 2025

Additional storms are expected to develop north of the area
Sunday evening and develop into a complex and dive south into
and possibly through the area Sunday night into Monday morning.
An unstable air mass will be in place but shear will not be
overly strong. Exactly where the MCS tracks will be dependent on
where the convection develops. The instability would support the
complex of storms moving south into the area on MUCAPE gradient.
However, the weaker shear and the wind fields by become more
west to east time. It is possible a line of storms develop but
becomes more outflow dominate when it moves into the area. With
the wind flow the outflow boundary could move more south away
from the showers and storms as they move more east with time
Sunday night into Monday morning. There is an SPC Marginal
Severe Risk (1/5) for damaging winds Sunday night into early
Monday mainly across the northern portions of the area as the
storms may weaken more to the south if the outflow races off to
the south. There will also be the potential for heavy rainfall
and localized flooding. Depending on the morning convection
there could be the potential for afternoon and evening scattered
storms as a front moves through the area on Monday, but of the
outflow destabilized things enough it is also possible once the
morning convection pushes out there rest of the day will be dry.

A slightly less humid air mass will be in place across the area
Tuesday into Wednesday with highs in the middle to upper 80s. Humidity
values will then start to increase later in week as highs in the
upper 80s to around 90 return to the area. Isolated afternoon
and evening storms will be possible later in the week.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1150 AM CDT Sat Jun 28 2025

An area of showers and scattered thunderstorms are currently
across southern Missouri late this morning. This activity will
continue to slowly move east across the area this afternoon into
early this evening. This activity should then overall dissipate
around sunset. The better coverage in storms may remain just
east of the TAF sites but some embedded thunderstorms within
the showers will remain possible. Later tonight into Sunday
additional bands of showers and thunderstorms are expected to
develop and move south through the area. MVFR to brief IFR
conditions will be possible with the storms today and again
tonight into Sunday morning.
