9/4 – Rob Knight’s “Labor Day Weekend” Forecast

Strong subsidence combined with low-level moisture has kept us rain free. A broad disturbance is has beginning to dip southward across the Great Lakes and will expand into the Appalachian Mountains this weekend. This will erode the western edge of the Bermuda high-pressure, opening up an area of weakness across the south central US between it and the high-pressure over the Desert Southwest. That means, back to more typical summer-time pattern with scattered to numerous afternoon showers and thunderstorms. Today will be a transition day with storms mainly west of I-55 as the Bermuda Ridge slowly retreats east.

Moving into the middle of next week, Models still suggests a much more potent trough will swing through and bring a strong cold front through south Mississippi.
