[/float]The necessary ingredients are coming together for a significant severe weather day in Kansas, western Missouri and Oklahoma. High instability and strong deep layer shear coupled with some surface boundaries will create an environment favorable for explosive supercell thunderstorm development this afternoon across southern Kansas, with the threat spreading into Missouri and Oklahoma later in the day. Given the parameters, strong tornadoes are possible with any storms that do form, with the storms themselves likely to be right-movers with very slow storm-relative motion. Dangerously large hail will also pose a significant threat.
