Areas affected...Southeast KS...West-Central MO

Concerning...Severe Thunderstorm Watch 298...

Valid 010717Z - 010815Z

The severe weather threat for Severe Thunderstorm Watch 298
continues.

SUMMARY...Severe Thunderstorm Watch 298 will be allowed to expire at
08Z.

DISCUSSION...A large area of thunderstorms persists from southeast
KS into central MO. Cold pool associated with these storms has
surged south to near the KS/OK, evidenced by the mid 60s
temperatures across much of southeast KS. Additional thunderstorms
are possible as a modest low-level jet contributes to warm-air
advection across this outflow. However, persistent convection over
the region has eliminated the steep mid-level lapse rates once in
place, limiting the overall severe potential. While a strong updraft
or two capable of isolated hail remains possible, the overall severe
potential has diminished enough to allow Severe Thunderstorms Watch
298 to expire at 08Z.

Mesoscale Discussion 0997

1250 PM CDT Mon Jun 12 2023

Areas affected...Portions of eastern CO into northeastern NM

Concerning...Severe potential...Watch possible=20

Valid 121750Z - 122015Z

Probability of Watch Issuance...60 percent

SUMMARY...A gradual uptick in thunderstorm coverage/intensity should
occur this afternoon, with large hail and severe winds possible.
Watch issuance may eventually be needed.

DISCUSSION...Modest low-level upslope flow continues across the
eastern CO and northeastern NM, with isolated to scattered
thunderstorms ongoing. Surface temperatures remain fairly cool as of
1750Z, mainly in the upper 50s to mid 60s. Even so, modestly
steepened mid-level lapse rates emanating from the higher terrain of
the Rockies should aid in the development of around 1000-1250 J/kg
of MLCAPE early this afternoon. 40-50 kt of deep-layer shear is
being fostered by an ejecting mid-level shortwave trough and
associated southwesterly jet. A few supercells capable of producing
large hail up to 2 inches in diameter will be possible. Some upscale
growth into small clusters may also occur with time, with perhaps a
greater threat for occasional strong to severe wind gusts. The
somewhat limited thermodynamic environment casts some uncertainty on
the magnitude of the severe threat. Still, observational trends will
be monitored over the next few hours for signs of increasing
thunderstorm intensity, which may prompt eventual watch issuance.
