A disturbance that dropped out of the Rockies is passing through the Central Plains early this morning and headed across the lower Mississippi Valley today. Rain chances are at the peak of this event this morning as most of the area seeing periods of light to moderate rain.
The few thunderstorms that do exist have been south of the coast. Rainfall accumulation should be fairly low around the ¼ inch mark.
The back side of the main rain shield should be east of I-55 by daybreak and east of Pascagoula by noon. Sporadic lingering light showers will be possible through a good portion of the day. Weak cold air moving in on the backside of this system will bring down temps a few degrees on Thursday.
The progressive upper level pattern that’s been bringing rain to the area every 2 to 3 days looks like it will persist through the rest of the week. Models show a disturbance more amplified than any previous others to move across the Mississippi Valley Friday night.
Southward digging of the base of the disturbance will reach into the western Gulf of Mexico off the Texas coast Friday. This will bring a wide swath of showers across at least the southern half of the forecast area. Once it moves east of the area Friday night, we should finally see at least a few consecutive dry days before the next system moves in.
