.DISCUSSION...
Issued at 247 PM CDT Sat Jun 1 2024

As of 230 PM, another complex weather pattern is emerging across the
Plains with multiple focal points for storm development. The first
focal point extends along a differential mixing boundary from near
McPherson to near Hays. Latest visible satellite reveals a deepening
cumulus field along the boundary with some agitation near Hays.
Forecast soundings along the boundary are quite favorable for severe
storms with considerable veering throughout the profile yielding
near 40 kt of effective shear. Therefore the strongest storms would
be capable of golfball size hail and damaging winds up to 60 mph.
Given the veering low-level wind profile, a tornado cannot be ruled,
especially in the immediate vicinity of the boundary. As diurnal
cooling ensues this evening, this zone of convection should
dissipate.

Our attention then turns westward once again to the second focal
point for storm development. A weak trough axis across far western
KS/eastern CO should allow for development shortly. Cold pool
mergers are probable through the evening with an eventual upscale
growth. Similar to this morning, it seems probable any MCS may
deviate southeastward into northern OK where the better low-level
theta-e resides. An additional complex may develop across western OK
and progress southeastward into portions of central KS. Again, the
overall lack of large scale ascent doesn`t lend to great confidence
in convective evolution. All of that to say, any organized MCS
overnight will be capable of damaging winds up to 65 mph.

A very similar setup is expected late Sunday into Sunday night with
convection developing across the higher terrain and progressing east
and southeast into Monday morning. Any organized MCS will be capable
of damaging winds up to 65 mph once again.

The active pattern will continue through at least Tuesday with weak
perturbations translating across the Plains atop a weakly to
moderately unstable environment. Confidence continues to increase
for the active pattern continuing into next weekend with the
potential for an amplified midlevel ridge axis sliding into the
Plains decreasing. This result would keep shower/storm chances going
and temperatures in the 80s.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 629 PM CDT Sat Jun 1 2024

VFR conditions are expected for the first few hours of the TAF
period. By 03Z tonight, thunderstorms, some of them severe,
will begin to encroach on the region. KRSL and KGBD are the
first terminals expected to see this thunderstorm activity.
KSLN, KHUT and then KICT will follow 2-4 hours after that. KRSL,
KGBD and KSLN are the most likely terminals expected to see
severe weather tonight with a lesser chance for KICT and KHUT.
KCNU is not likely to see thunderstorm activity until closer to
10Z but by then, this activity is expected to be sub-severe but
still contain heavy rain. After 14Z tomorrow, VFR conditions are
expected to return.
