A few storms possible, but the heat continues: Southern MS/AL/LA Weather Forecast – 9/12/23

The shot for rain during the next 48 hours is looking a bit better – but still not great. The hi-res guidance came back this morning showing hit and miss showers and maybe a few storms this afternoon and evening and then again tomorrow morning. And perhaps even another shot on Thursday morning.

While there isn’t a “big” change on the way, it does look like things get a little less “dog days of summer like” as we move into next week. Overnight lows look to ease back into the upper 60s – for the entire week.

Now, the average high and low for this time of year is a high of 88 and a low of 68, so we should be closer to normal next week.

On the chart below, you can watch the temperatures undulate between around 70 and around 90 for the next 15 days. But we do lose a bit of humidity as we move through the early parts of next week, which should help us drop overnight lows into the 60s.

Looking out a bit further in time, at the 40-day model guidance for temperature a precip, things look to remain pretty warm

Keep in mind, these 40-day model runs are far less accurate (even in the short term) than the regular forecast. That is why it shows cooler temperatures during the next few days (which are not very likely). But I think it can give us a good general idea about what to expect during the next month or so.

And what the chart above say is, “prepare for continued warmth.”

It also shows a cool down finally coming – with some rain – as we get into the first week of October. So that may be something to keep on your radar in the coming weeks, too.
