April 3rd, 2008 - North Texas

Looks like a decent chase day setting up. Not sure about total tornado threat, but a nice beast of a storm seems likely with very large hail. Good moisture in place so instability will be large. Just a matter of the low level winds responding/backing after the passage of the lead upper wave. Could be a late show, if there is a sigtor. Targeting SPS and points just S later this afternoon.
Although helicity will be marginal, the very large CAPE and steep lapse rates can sometimes work magic, as can a deviant right moving storm. I still have hopes of seeing a tornado today, or perhaps early evening.
