.SHORT TERM /THROUGH SATURDAY/...
Issued at 242 PM CDT Fri Jun 28 2024

Residual shower activity, some of which may not be reaching the
ground, from overnight convection in Kansas was moving across
the region this afternoon. The associated cloud cover was
helping to limit the heat this afternoon. Most readings across
the Ozarks were in the middle 80s to around 90 degrees or right
around average for this time of year.

An upper level wave, albeit weak, along with an inverted trough
across the plains was helping to tighten the surface gradient
this afternoon. This has allowed for gusty winds to develop with
20-30kt gusts measured at times. As the upper trough moves east
overnight tonight it will begin to drag trough and attendant
cold front across the plains towards the Ozarks.

Looking at the synoptic pattern and output for CAMS for tonight
into Saturday morning there is a potential for some strong to
severe storms. The CAMS were either rather robust with
convection or non-existent. In looking at the  output, there is
the possibility for wind gusts to 60 mph and hail to quarters
in size where storms can take advantage of the instability in
place (MLCAPE 2000-3000j/kg) however, lapse rates are modest and
convergence is not really strong. The best potential loos to be
across central Missouri, though if a cold pool develops or the
system develops into an MCS it may make its way to the Arkansas
State line, but question remain in this occurring. With that
said there is a SPC Slight and Marginal risk across the northern
portions of the Ozarks for tonight, after Midnight into
Saturday.

During the day Saturday temperatures are expected to climb into
the middle to upper 90s with heat indicies in the 103 to 110
range thanks to strong warm air and moisture advection ahead of
the cold front. This has resulted in a Heat Advisory being
issued for all of the area from 10am through 8pm.

With the heat and the vicinity of the front as it moves south,
isolated showers or storms may develop during the day but
coverage and confidence in this is limited.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Issued at 242 PM CDT Fri Jun 28 2024

The cold front will make its way through the region Saturday
night into Sunday morning with the front and any attendant
storms or rainfall moving south of the region by lunchtime.

The cooler air moving into the region behind the front will
bring a respite from the heat with high Sunday only in the lower
to middle 80s.

The break in the heat will be brief however as ridging returns
and temperatures climbing rapidly into the 90s with heat
indicies above 100 again by the middle of next week. If these
trends continue, heat headlines may be needed again next week.

Precipitation chances return mid- to late-week as another trough
moves through behind the ridge. Hot an humid conditions are thus
expected through next week and into the 4th of July with
additional chances for showers and storms into the coming
holiday weekend.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1231 PM CDT Fri Jun 28 2024

Cloud cover left over from overnight storms across eastern
Kansas and northern Missouri will linger today across the
region. Some breaks in the clouds will occur but at least as
coverage is expected to remain mainly scattered at and below
20-25kft. Surface winds will be southerly and gusty at times to
20-25kts.

A storm system is forecast to moving into the region overnight
(around/after 06z) and bring the potential for thunderstorms
and lower ceilings and visibilities. While storms are possible,
the lack of some ingredients for widespread storms limits
confidence and coverage.

In advance of the system, low level winds across far southern
Missouri and the KBBG terminal will produce LLWS from 07-12Z.
