Scattered Storms Through the Weekend and Into the Start of the Workweek

| August 29, 2020 @ 5:00 am


We’ll have more waves of showers and storms move through the area today, most of which will be from the moisture fetch of Laura. The good news is that moisture levels will drop throughout the day as dry air will be advected into Central Alabama, therefore rainfall amounts will not be as high. However, showers and storms will be likely, especially by the afternoon and early evening hours. Highs will be in the upper 80s to the lower 90s.

The effects of Laura will be long gone on Sunday and we could possibly see some subsidence form over much of the area behind Laura. While models have shown showers and storms becoming likely, we’ll reduce that a little bit and say there will be a decent chance of scattered mainly afternoon showers and storms. A couple of storms may become strong to marginally severe with the possibility of isolated damaging wind gusts. Highs will be in the upper 80s to the lower 90s.


Unfortunately, moisture returns on Monday as a trough will be digging in to our west, allowing moisture-rich air to flow in from the southwest. Showers and thunderstorms will be likely mainly in the afternoon and early evening hours. Highs will be in the mid-80s to the lower 90s.

Much of the same story for Tuesday as showers and storms will be likely mainly during the afternoon and early evening hours, but coverage of those should be a little less. Highs will be in the mid-80s to the lower 90s.

Subsidence sets back in across the area on Wednesday and Thursday as high pressure builds over the southeast just to our east-northeast. There will be plenty of sunshine on both days but we may have an isolated shower or storm during the afternoon hours. Highs on both days will be in the upper 80s to the lower 90s.

We’ll have a slight rise in the chance of scattered afternoon showers and storms on Friday, but the good news is that most locations will stay dry. Highs will be in the mid-80s to the lower 90s.


At 12:30 am: A tropical wave located about 600 miles east of the Windward Islands is producing disorganized showers and thunderstorms. Some gradual development of this system is possible during the next several days while it moves westward at about 15 mph toward the Lesser Antilles. Regardless of development, this system will likely produce gusty winds and locally heavy rainfall across portions of the Windward and Leeward Islands on Sunday.
The formation chance through the next five days is low at 30 percent.

Another tropical wave is located over the eastern Atlantic Ocean just southwest of the Cabo Verde Islands. This system is expected to move very slowly for the next several days, and some development is possible early next week over the eastern or central tropical Atlantic. The formation chance through the next five days is medium at 40 percent.

The rest of the Atlantic Basin is quiet.


2005 – Hurricane Katrina made landfall in Plaquemines Parish in southeastern Louisiana early on the 29th with maximum sustained winds near 125 mph, a strong category-three, and the third most-intense landfalling hurricane in U.S. history. The center of the hurricane passed just east of New Orleans, where winds gusted over 100 mph. Widespread devastation and unprecedented flooding occurred, submerging at least 80 percent of the city as levees failed. Farther east, powerful winds and a devastating storm surge of 20-30 feet raked the Mississippi coastline, including Gulfport and Biloxi, where Gulf of Mexico floodwaters spread several miles inland. Rainfall amounts of 8-10 inches were common along and to the east of the storm’s path. Katrina weakened to a tropical storm as it tracked northward through Mississippi and gradually lost its identity as it moved into the Tennessee Valley on the 30th.
