The Storm Prediction Center in Oklahoma has placed parts of North Texas under a Moderate Risk for Severe Weather, beginning late Saturday. This should not be taken lightly this time of the year.
A very strong storm system will be featured over the Four Corners area and this system will have whats called a "triple point axis". To simplify, this means that a Low Pressure System will include a Stationary Front (the one we've had all week), a Cold Front, and a Dry Line.

The greatest Tornado threat will be near the axis of the Triple Point and on the image above that's where the arrow is pointing to. That's where the greatest areas of wind sheer will be and that's where storms are most likely to rotate. On Saturday this area will be in most of Oklahoma and into the Northwest portions of North Texas, west of DFW. On Sunday the entire system will shift further East and I don't want to predict at this point what Sunday will be like except to say that thunderstorms are a very good bet. I would like to see another couple of computer model runs before we get a good handle on Sunday. We will have another post by Friday afternoon.
