Scattered Storms Continue…Weekend Forecast…Bama Gameday Forecast – 6:20pm Update Wednesday

Good Wednesday afternoon to you! The weather across the deep south has been very active today due to the large Isaac. The system is moving to the northwest and is slowly pulling away from the New Orleans Area. As the storms moves well inland, it is weakening, so look for the strong winds around Isaac to die down a bit over the next 12 hours. It’s a little breezy in central and west Alabama, but it’s only helping to make our local weather feel rather pleasant. A few storms have moved across central and western Alabama, but there is no problems with flooding around our area. Since Isaac is far enough southwest of our area, the big problems are out of our area.

The risk of scattered storms will continue over the next couple of days, but rain chances will gradually drop by the time we reach Labor Day Weekend. Skies will remain mostly cloudy through Friday. I can’t rule out an isolated tornado this evening or on Thursday, but the chance is very low. The best chance of showers and storms will occur in western Alabama today and on Thursday. Keep the rain gear handy across all of west and central Alabama because storms will move in fast. It will not rain all day, and not everyone will pick up all that much rain.

Labor Day Weekend is looking nice for the most part. There will be some storms in the area, due to the soupy airmass in place from Isaac. The chance of rain on Saturday and Sunday stands at 40%. While thunderstorms will develop in spots, it will not rain all day. The best chance of storms will occur during the afternoon hours both Saturday and Sunday. Keep the rain gear handy. Expect skies to become partly cloudy over the weekend. Rain chances continue to drop early next week.

Alabama takes on Michigan in Dallas on Saturday. If you’re heading out to Cowboys Stadium, it will be hot outside the dome, with temperatures in the 90s during the day. Isaac will have no impact on the outdoor events surrounding the game. Keep in mind you may have to drive through the mess on the way to Texas, but conditions will improve quickly west of Louisiana from Isaac.

Storms At Times Today Through Friday… Bad News From The New Orleans Area! – Wednesday Morning Forecast 9am

Good Wednesday morning. As of 9am, Isaac is still a hurricane over south Louisiana. The storm is causing major flooding issues across southeast Louisiana, south Mississippi and extreme southwest Alabama. There have been reports of levees topped near the New Orleans area due to storm surge. Water rescues are ongoing now in parts of that area, where water has risen to 12 feet on some houses! We’ll know more over the next few hours. While it’s just a category 1 storm, it’s a very large storm. That has allowed the surge to build up in areas of the Alabama, Mississippi and Louisiana Gulf Coast. Since the storm is nearly stationary, the water continues to pile up across southeast Louisiana, causing big issues. The very heavy rain may cause a flooding situation in New Orleans due to the long duration of heavy rains. The pumps there may not be able to keep up.

Our local weather has been pretty quiet, despite Isaac moving across the northern Gulf of Mexico and into southeast Louisiana. Some dry air got pulled into Isaac yesterday and on Monday, so that really dried up much of the outer rain bands of the storm. That being said, instability will cause storms to fire up further away from Isaac late this morning and into the afternoon hours. I expect a good chance of scattered banding showers and storms around Isaac this afternoon and evening. We’re just close enough to the storm to bring the risk of an isolated tornado today or on Thursday. I think the chance of that is small, but we’ll need to watch the radar. The main risk low end risk will occur in areas southwest of Tuscaloosa today and west of I-65 tomorrow. If a tornado develops in our area, it will likely be small and not last long at all.

This has been a tough storm to forecast for sure due to a nearby trough and ridge. The ridge seems to be winning the battle and has pulled Isaac far enough away from our area to keep the big issues our of here. As the storm tracks northwest over the next couple of days, we’ll be on that east, unsettled side of the storm, so scattered storms will be possible at any point today, Thursday and Friday. Look for highs to remain in the 80s. It will not rain all day, but keep the rain gear handy incase storms move over your area. Expect breezy conditions around the storms that develop.

The chance of rain drops off this weekend to 30 or 40%, so many areas will deal with a pretty nice Labor Day Weekend. While there’s a risk of a few storms here or there, don’t expect an all day type of rain. Skies will become partly cloudy over the weekend, with highs near 90.
