Southern MS / AL / LA Weather Forecast – 9/23/21

Things continue to look boring during the next few days. In fact, mostly sunny skies and no chance for rain will be the forecast through about Sunday. It looks like by Monday, another shot for rain will sneak back into the forecast.

And the chance for rain on Monday even looks pretty meager. We are talking a 10-percent shot at this point. At best.

Depending on which model you look at, there may be some more rain that tries to push back into the region by Wednesday or Thursday. The GFS computer weather model is a little drier while the ECMWF computer weather model is a bit wetter.

Both suggest by late next week, the chance for rain returns. But each one suggests it returns underneath completely different atmospheric conditions.

And, honestly, neither is correct. There are probably little pieces of each that are accurate, but overall, either of these will end up verifying. Both look a bit goofy for different reasons.

So, for now, I’d say: “Enjoy the weather!” because beyond about six days out the forecast starts to diverge a bit and we don’t have a clear indication about what it will look like
