Stick a fork in the rest of May. The upcoming pattern looks good if you like rain, in fact many areas in the SGP, panhandles of TX and OK, KS, etc., will benefit greatly from the moisture. The cut off low now in southern California takes its sweet time meandering barely eastward and guarantees there will be very little return flow from the GOM to moisten things up in the traditional chase areas of tornado alley. The mid level pattern shows a possible day in MT next week where you could chase, but other than that there isn't much on the horizon to get excited about. June is just around the corner it seems.
