.DISCUSSION...
Issued at 251 PM CDT Mon Jun 24 2024

At mid afternoon, water vapor satellite showed a weak mid level
perturbation moving across western Kansas at 19Z. Some cumulus was
starting to develop over parts of central and south central Kansas,
but overall skies remained clear across north central and northeast
Kansas. Hot temperatures in the upper 90s to low 100s along with
dewpoints in the 70s for much of the area were producing heat
indices in the 104 to 112 degree range as of mid afternoon.

Cannot rule out some isolated convection developing across central
Kansas late this afternoon and moving into north central Kansas.
Will add a low probability (around 15%) to account for this where
deepest mixing was occurring. Inverted "V" soundings would suggest a
potential for a strong wind gust. Additional storms could move in
from western Kansas or southern Nebraska later this evening and
overnight. The convection is expected to end during the early
morning hours on Tuesday.

For Tuesday, another day of excessive heat is expected with the
thermal axis extending from the southern Plains across eastern
Kansas. Highs again will be in the mid 90s to near 100 with heat
indices of 104 to 109 in the afternoon. A frontal boundary is
forecast to move southward across Nebraska and into parts of
northern Kansas late in the afternoon to early evening. A mid
level wave moving across the central and northern Plains will
aid in pushing the boundary southward. Better forcing looks to
be focused to the north into Nebraska and Iowa. Storms that
develop along the front would move southeast into northeast
Kansas. Further west more isolated storms will be possible
across central Kansas. Expect convection to develop by late
afternoon or early evening. Highest probability (60-70%)
continues to look like east of Highway 75 into Missouri.

Cooler temperatures are forecast for Wednesday and Thursday behind
the front with high pressure building south. SOme convection may be
possible Wednesday night into Thursday morning with storms
developing in the western high Plains then moving eastward through
the night.

The thermal axis returns on Friday with southwesterly flow across
the southern and central Plains. Heat indices will once again rise
to around advisory levels of 105 degrees.

VFR conditions are expected. Precipitation chances remain rather
low though not quite zero for much of this period. South-
southwest winds will dominate, with diurnal gusts being the main
change. A moderate nocturnal low-level jet is anticipated, but
little if any direction change from surface winds should only
result in some turbulence.
