For Wednesday, the severe threat shifts eastward with the ongoing MCS in eastern Nebraska.  Seasonably-rich moisture will continue to advect northward into the Mississippi and Ohio valleys which – in combination with steep lapse rates – will yield strong instability.  However, given our need for a clean pre-convective environment (for our GOES-R products), we are not certain that we will operate in this area (the High Plains may provide a better opportunity).  Given the uncertainty regarding the greatest severe threat tomorrow, I will refrain from specifying any specific CWAs for operation.   Our shift will begin at 12:30 pm in the Development Lab.
