Stormy Night On Tap

Have just been examining this evening's 00 UTC soundings. Very substantial CAPE from north-central Texas, across most of Oklahoma, and eastward across northern Arkansas and southern Missouri. Much of this region will experience strong low-level warm advection during the coming night and substantial severe thunderstorm activity is probable, even though the afternoon has generally been supressesed. First strong storms have just developed over western Oklahoma and they may reach to southern Illinois before morning. See Springfiled, Missouri sounding above, which is primed for rapid storm development.
