Strong Disturbance To Create Severe Weather In South Plains; Snow Potential Later On?

This is a projection from the GFS model of 500mb heights- the area where one is most easily able to identify disturbances or high pressure systems.

The circled area is something I am closely watching- and is tied to a new theory I am working on. This disturbance is very strong, and is likely to end up this strong despite the model showing this forecast in the long range. However, notice the swath of blue across the Southern Plains. This is a high pressure ridge that will keep this disturbance from moving east.

Notice the disturbance to the west of Washington and Oregon. This disturbance should move southeast and give the main disturbance the kick it needs to shove itself east. This means that we should be seeing a good severe weather event across the Southern Plains and probably into the Southeast.

A little more on that disturbance to the west of Washington and Oregon- the way the 500mb flow is depicted, this system should crash into northern California. In the wake of a strong disturbance in the Upper Midwest and Great Lakes, this area of low pressure should move east and may very well provide an opportunity to let some flakes fly in portions of the Midwest. The models will change, but that is what I am seeing at the moment.

Hello Andrew! Another rainy night ahead for me in the Ohio area.No problem by me.We have been getting DRENCHED since the middle of September.Hopefully this pattern keeps it up!Maybe this could be a sign what the winter pattern might be like,hopefully snow not rain though.We would have been buried with snow last winter considering all the rain we had here in Ohio.
