2/21 – Rob Knight’s “Disruptive Weather” Morning Forecast

T-storm activity this morning across extreme southwest Mississippi will continue to move north. Areas of locally dense fog across the area will continue as a a DENSE FOG ADVISORY is in effect through mid-morning.

Otherwise, scattered showers and a few thunderstorms will plague the forecast area through the end of the workweek as a nearly stationary frontal boundary draped across the area serves as a focus for convection. This boundary will begin moving northward as a warm front later tonight and then push to the north of the forecast area during the day on Friday. Convection is likely to be more concentrated across the northern sections of the forecast area through Friday. Areas of fog, possibly locally dense, will likely be a problem again tonight and Friday morning.

Another potent system will affect the region with a strong cold front across the forecast area late Saturday/night. Although the best dynamics will bypass the local area to the north,

sufficient instability may allow for the development of a few strong to possibly severe thunderstorms Saturday afternoon and evening…with the best chances across southwest Mississippi.

The area will finally have a chance to dry out a bit in the wake of this front for Sunday and Monday as high pressure builds into the region and brings with it some cooler air. The dry period will be short-lived, moisture will return northward by Tuesday in advance of another cold front that will push across the Gulf Coast region Wednesday into Thursday.
