Shown above is the 500 millibar forecast from the GFS Ensembles over the Northern Hemisphere. We see pressure contours clumped very close together in the Pacific Ocean, with low pressure anomalies in the Bering Sea and very weak/nonexistent high pressure anomalies off the coast of East Asia. These two factors will act to tighten the Pacific jet stream and really pump up storm systems that cross the northern Pacific. The persistent low pressure in the Bering Sea will shed off pieces of energy that will then crash into the Pacific Northwest region of the United States, or into southwestern Canada. Due to the already-active subtropical jet stream (another, weaker jet stream that is present in the South US, does lead to Nor'easters when storms go in that path), I anticipate the Pacific Jet Stream to drop south into the southern Plains and have the two jet streams merge in that region at least once in the next 7 to 14 days. When this merging happens, the storm itself will strengthen and we will see at least a modest chance of severe weather along the Gulf Coast, depending on where the system goes. If the subtropical jet stream captures that piece of energy, it could become a Nor'easter. If the polar jet stream catches it, the Midwest and Ohio Valley could benefit.
