Areas affected...Southeastern Kansas into southwest Missouri

Concerning...Severe potential...Watch unlikely=20

Valid 112044Z - 112245Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated large hail and severe gusts will be the primary
threats with storms that can develop along an outflow boundary. A
watch is not anticipated this afternoon.

DISCUSSION...Convection from last evening into this morning left an
outflow boundary across parts of southeast Kansas into southwest
Missouri. A subtle surface low is also evident just east of Pratt,
KS in surface observations. Convergence along this boundary has
promoted modestly deepening cumulus over the last few hours. Of
particular note are more agitated cumulus from near Emporia, KS to
south of Eureka, KS. Additional towers are developing northwest of
Springfield, MO. The exact area of where strong/severe storms will
develop is not certain. CAM guidance has generally suggested robust
storm initiation will occur by late afternoon; however, with greater
low-level moisture near the boundary than forecast in models, this
may occur sooner than anticipated.

With weak upper-level support, storm coverage should remain
isolated. Strong buoyancy (2000+ J/kg MLCAPE), effective shear of
25-30 kts, and steep mid-level lapse rates will promote a risk of
large hail and severe wind gusts. With temperature-dewpoint spreads
nearing 30 F (primarily in southeast Kansas), some upscale growth
could occur with cold pool mergers. A locally greater severe wind
threat would be present should that occur.
