More Severe Weather Today?

SPC has issued a slight risk for severe weather today across portions of Texas, Oklahoma and Kansas.  High instability will develop bring a retreating warm front across Oklahoma and northern Texas this afternoon. Very high CAPE numbers > 4,500 and EHI values >3 will create an environment cable of explosive storms if they do develop. With the lack of any main triggers in the atmosphere storms will have to rely on small boundaries and just instability maxes. On the map above I have highlighted the SPC slight risk zone and in the pink my highest threat zone for later today.  Right now expect storms if they do form to start building around 5pm. I'll have other update later this afternoon. -Justin-
