The southern Plains is bracing for another round of severe weather today. Multiple tornadoes in Colorado, Wyoming, Texas, and Oklahoma were just a precursor to today's event. The difluence aloft is tremendous with a very strong curved jet present aloft. A very well defined dryline, low level jet (LLJ), and drier cooler air aloft make for a perfect recipe for a sever weather outbreak.
The SPC just upgraded the severe weather risk to High across central Oklahoma. It will be interesting to see the 18 or 20z soundings that will be sent off this afternoon. The storm relative helicity looks to be large again, probably exceeding 350 and maybe even over 400 for most of Oklahoma east of the dryline.
The MCS that passed over this morning has moved out and solar heating can begin again as the dryline starts to tighten in western Oklahoma/eastern Panhandle of Texas. Look to bulges in the dryline for enhanced convergence and storm producing areas as well as high pockets of theta-e next to a tight gradient of theta-e. These are favorable areas for chase windows.
If you are in the Wichita Falls, TX TV area, be sure to tune into your CBS station and watch friend of the blog Ben Walnick do his thing. I also know that Joey P and Rick H aka Maverick will be out chasing today, but I doubt they will have to go very far.
I will update more in a couple of hours.
