11/29 – Rob’s “Black Friday/Weekend” Forecast
Another quiet weather day is in store for the forecast area today with high-pressure and at the surface. This pattern will shift to the east on Saturday as a deep mid/upper level low pressure system moves out of the western U.S. and into the Central Plains. This will be the next weather maker for the local area. Return flow out ahead of this system will advect a warm and moist airmass back into the central Gulf Coast region on Saturday. As the storm system moves eastward, it will push an associated cold front across the forecast area Saturday night into Sunday morning. T-storms activity is expected to develop near and along the frontal boundary and move from west to east across the area from late Saturday afternoon through the early morning hours Sunday.
There will a potential of a few strong to severe thunderstorms with the greatest threat generally along and to the west of Interstate 55 corridor. The SPC has highlighted a Slight Risk of severe thunderstorms across about the northwest half of the forecast area with a Marginal Risk for severe thunderstorms across the remainder of the forecast area…with the main threat being strong winds In the wake of this system, cooler and dry weather will again be observed with northwest flow aloft prevailing into the middle of next week.
Another chance for rain will be in the offing for the end of next week…Thursday night into Friday…as a disturbance moves across the lower Mississippi Valley and Gulf Coast states.
