   Areas affected...Southeast Kansas

   Concerning...Tornado Watch 15...18...

   Valid 070242Z - 070415Z

   The severe weather threat for Tornado Watch 15, 18 continues.

   SUMMARY...The severe threat may increase across southern/southeast
   Kansas over the next couple of hours as a cold front pushes into a
   favorable convective environment.

   DISCUSSION...Recent radar imagery from central/eastern KS shows
   ongoing convection being undercut by a strong surging cold front,
   which has largely limited overall convective intensity so far this
   evening. GOES IR imagery depicts new attempts at deep convection to
   the northwest of the Wichita, KS area as the front begins to push
   into a pocket of 1500-2000 J/kg MLCAPE. The KICT VWP also depicts
   very strong low-level helicity on the order of 600 m2/s2. The
   combination of new convective development within this conditionally
   favorable environment suggests that some uptick in severe potential
   is possible in the coming hours across south/southeast KS - most
   likely manifesting as a severe wind and tornado threat as storms
   quickly grow upscale. However, it remains to be seen whether
   deeper/stronger convection across this region can remain rooted
   along/ahead of the front. If undercutting occurs, the overall severe
   threat may remain somewhat limited. 

   Ahead of the front, multiple attempts at sustained deep convection
   have been noted to the east/southeast of Wichita, KS, likely the
   result of increasing isentropic ascent associated with the onset of
   the nocturnal jet (per KICT VWP data). While cell maturation has
   been limited owing to the relatively nebulous forcing for ascent,
   this convection is developing in an environment supportive of
   supercell development (though it remains unclear if one or more
   cells will be able to mature prior to the arrival of the front).
   While confidence is low, any cell that can develop across this
   region may be able to realize the highly favorable environment
   (characterized by STP values around 3-5) and pose a threat for
   large/very large hail, severe wind, and tornadoes (including the
   potential strong tornadoes).
