A large upper level low will dig into the central part of the country in the next few days, bringing with it severe weather and the chance for tornadoes. The models are coming into agreement that this low will become cut-off, meaning it will be quasi-stationary for a few days until it gets picked up by the main flow. In terms of storm chasing this means there will be a series of days where severe weather will be possible. The wind fields with this system are impressive, and right now the models are depicting quite a lot of directional shear, or a lot of turning with height. One limiting factor, and this seems to be becoming a reoccuring theme for this season thus far, is the amount of quality moisture that returns from the Gulf of Mexico. A series of cold fronts has scoured out much of the Gulf. However, with the impressive dynamics of this system, I would not be surprised to see quite a few tornado reports from Thursday through Saturday!
