.MESOSCALE DISCUSSION...
Issued at 533 PM CDT Sun Jul 4 2021

Well it turns out the HRRR was the odd man out and completely failed
to capture reality of the storms that are currently ongoing. Meso
analysis suggests that there is plenty of CAPE and marginal shear
for low end supercells to continue for the next hour or two.
Areal coverage of WSR-88D is increasing over the last hour.
Eventually do expect a threat change (from increased beneficial
competition... ) the hail risk will decrease and the wind threat
will increase. We probably still have another good hour or two
before this threat changes based of radar and short term guidance
trends. Additionally, upscale growth will probably develop later
on in the storm evolution.

.SHORT TERM...(This evening through Monday)
Issued at 222 PM CDT Sun Jul 4 2021

Well humans will not being the only thing that is sparking off some
excitement tonight. The atmosphere will be too. Spoiler alert: think
the atmosphere will win tonight in terms of impacting weather across
southwest Kansas. Early afternoon surface analysis shows that a low
as formed across far southeast Colorado. A field of stratocu to cu
has developed across far southwest Kansas and northward towards Hill
City. This is the area to watch for storm development. Meso models
like the ARW, NSSL-WRF, RRFS and global models like the EC all break
out convection in this general area late this afternoon. The HRRR seems
to be the odd man out and keeps the area devoid of convection. Looking
at this model more closely, there is no CAP present, so not so sure
why this model is being conservative with convective growth. Looking
at satellite water vapor channel shows a subtle wave moving through
the greater region, so this is upper level support to help trigger
storms. This upper level wave will also increase bulk shear to 30 knots
this evening, so there will be marginal shear that is supportive of
marginal supercell structures.

Right now, have the highest pops aligned with the latest thinking that
storms will develop along the Highway 83 corridor this afternoon. Storm
movement should be to the south. Forecast Skew-t's/log-p's show a profile
that is favorable for large (1-2") hail and damaging winds. PWATs are
high right now, so there should be some beneficial competition on hail
embryos to cut down on any significantly larger hail (2+"). Anticipated
upscale growth should then transition the hail threat to a wind threat.
The low level hodograph and thermo profile is not favorable for tornadoes.
Hail with the initial supercell like structures, followed by outflow
winds of 60+ mph, and heavy rainfall are the main threats for this
event. Those citizens, particularly west of Dodge City, should heed
any warning, take shelter indoors, and post-pone the fireworks until
it is safe to resume to do so. A large downburst with fireworks can
be extremely dangerous and lead to an uncontrolled fire. Bottom line,
pay attention to the weather for tonight if you are outside.

All this activity should exit the FA by 10 or 11 pm plus/minus an
hour.

The atmosphere should be pretty worked over on Monday. The net result
is a dry forecast with a high around 90F. Winds will be relatively
light throughout the day.

Overnight mins heading into Tuesday morning will be seasonal with values
mainly in the mid to upper 60s.

.LONG TERM...(Monday night through Sunday)
Issued at 222 PM CDT Sun Jul 4 2021

The EC is still indicating a fropa late Tuesday and into Wednesday.
Convection will still be possible along this front also also behind
in the post-frontal upslope flow pattern. The NBM pops look fine enough
for now during this period.

After a brief cool down midweek, highs will quickly rebound to seasonally
hot values with 90s likely by the end of the business week.

Friday could end up being the warmest day as we enter the tail end of
the westerlies with some downslope component to the winds. Upper 90s
may be realized here. Don't see any guidance to suggest warmer than
than that currently.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 515 PM CDT Sun Jul 4 2021

Scattered thunderstorms will continue to develop and spread south-
southwest across portions of southwest and central Kansas through
late evening, potentially affecting the vicinity of all TAF sites.
Otherwise, primarily VFR conditions are expected to prevail through
early Monday morning. South-southeast winds around 10 to 20kt are
forecast to persist through early Monday as a weak lee side trough
of low pressure remains anchored in eastern Colorado.

This hazardous weather outlook is for portions of central...south
central...southwest and west central Kansas.

.DAY ONE...Today and tonight.

Day 1 Discussion
----------------

Slight risk for severe thunderstorms for far southwestern counties
where quarter sized hail and damaging winds up to 60 mph will be
the main threat Sunday afternoon. These will spread east into the
evening hours where marginal winds will be the main threat as the
night progresses towards sunset.

Day 1 Hazards
-------------
* Hail: Limited risk
* Thunderstorm wind damage: Limited risk
* Lightning: Limited risk

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Days 2-7 Discussion
-------------------

A cold front will push through Tuesday evening that will spark
another round of scattered thunderstorms with lightning the main
threat at this time. Severe weather is still possible but not
expected associated with the aforementioned frontal boundary. This
will linger into Wednesday morning before exiting out of the CWA
into south central Kansas and Oklahoma. No other hazards are
expected the remainder of the period.
