Issuing a high risk last weekend would have been irresponsible given the uncertainty. And issuing a high risk this morning also would have been irresponsible, regardless of the outcome.
Yet another difficult forecast this morning. There will be some regions of the warm sector with higher end parameters, but the CAM guidance is far from screaming "outbreak." To me, it looks like we'll have another QLCS event with the chance of some rogue isolated supercells in the warm sector (though CAMS are all across the board in terms of the prevalence of the later). QLCS tornado events are quite difficult to forecast. Obviously last week's event was prolific, and there are some similarities this week (low-level saturation). But there have been plenty events with high end parameters in the warm sector and a QLCS that plowed through the high end parameter region without producing many tornadoes. Given these uncertainties (which to me seem a tad up from last weekend), it would have been totally irresponsible to issue a high risk.
