2AM Day 3 Convective Outlook for Monday, September 1. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
A strong storm or two cannot be ruled out in the central or southern Plains on Monday.
Synopsis
A broad northwesterly upper flow regime will become established over the Plains and MS Valley as upper ridging remains in place across the Interior West on Monday. Surface high pressure will be commonplace across much of the MS Valley to the East Coast, as well areas west of the Rockies. Rich low-level moisture will meander over the Plains and Gulf Coast region, serving as a primary fuel source for thunderstorms. A diffuse surface front will sag southward across the southern Plains as weak mid-level impulses overspread the Plains, serving as lifting mechanisms for deep-moist convection. A couple of strong storms with sub-severe wind and hail cannot be ruled out. However, the threat for organized severe appears too low to warrant the introduction of severe probabilities this outlook.
