Areas affected...Parts of southwest/south-central KS and northern OK
Concerning...Severe potential...Watch possible=20
Valid 060032Z - 060300Z
Probability of Watch Issuance...60 percent
SUMMARY...The area is being monitored for an increasing severe risk
into this evening. A watch could eventually be needed for parts of
the area.
DISCUSSION...Latest visible satellite loops show recovering
sheltered boundary layer air and backed surface winds over parts of southwest/south-central KS into northern OK ahead of a weak surface
low and dryline evident over the TX/OK Panhandles. While this air
remains slightly capped amid generally weak large-scale ascent per
the DDC 00z sounding and visible satellite imagery, a few deepening
cumulus towers are becoming evident along the eastern and southern
edge of anvil debris overspreading the area from eastern CO. As lift
along the nose of a strengthening low-level jet advances northward
this evening in conjunction with a passing shortwave trough,
eventual convective initiation will be possible where surface
convergence is being maximized ahead of the surface low, though
large uncertainty remains.=20
If isolated convection can initiate along this corridor prior to
substantial nocturnal boundary-layer cooling, increasingly large, clockwise-turning low-level hodographs (200-400+ m2/s2 effective
SRH) amid strong instability would support a discrete supercell or
two along the KS/OK border capable of all hazards prior to upscale
growth with southward extent. Timing and location of convective
initiation and subsequent evolution is still unclear, though current
thinking is that a watch could eventually be needed for parts of the
area this evening.
