Another complex storm system possible next week
On the heels of a large, complex storm system which impacted a large portion of the United States over the past several days, forecast models have continued to hint at the development of another system in 5 to 7 days time. Instead of being just long range model fodder, the hemispheric pattern progression suggests that this storm threat has some legitimacy, with the potential for a moderate to high precipitation event across the Eastern United States once again during the middle part of next week.
Much of the storm threat stems from the development of a cut-off low, or a trough and low pressure system cut-off from the jet stream, in the Southwestern United States later this week and weekend. This cut-off low looks likely to meander in that area for a period of time before ejecting east/northeastwards. The orientation of the upper level jet stream and height pattern suggests that the storm will eject from the Texarkana area towards the Mississippi and Ohio River Valley’s by the early and middle part of next week.
