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. ..Wendt/Guyer.. 07/11/2024 ...Please see www.spc.noaa.gov for graphic product...
