Storms possible by tomorrow morning, some severe risk, then a nice weekend: Southern MS/AL/LA Weather Forecast – 3/2/23

Whether or not you see any storms, it will be breezy.

Sure, we still have a chance for a few showers today and tonight and then storms as we head through the early morning hours tomorrow morning. While not every spot will see a storm, everyone will see the wind.

For the storm potential, I bet I can post just two graphics and most of you guys would probably know what to expect.

The numbers have come down a little on the Karrie Meter. Recall yesterday we were at a 4.13 and this morning we are at a 3.39. So not a “big” change, but I think it is a meaningful one. But the “TOR LEAN” number has come waaaayyyyy down.

And I had a hunch it was going to change. I just didn’t know it would change this much.

Like the Blog, you’ll love the NEW NickelBlock Forecasting app!

The thing that is benefiting the region the most is the timing. Storms look to roll through around sunrise, whent eh atmosphere is, generally, most stable.

Looking at the data this morning, it looks like we may hold on to a pretty decent cap of warm air aloft as the front rolls through. So storms will likely have a tough time getting going because of that. And where storms are able to break through the cap, there won’t be much room for instability above that, so they will likely struggle to really get moving.

And the shear is going to be quite high, so any updrafts that try to get established are going to have a really tough time staying upright. A bit like I talked about yesterday, these storms will be drunk on shear.

Because of the cap of warm air, we won’t likely see too many storms ahead of the cold front, either. That means the forecast from yesterday (or the day before, I honestly forget when I mentioned this), the storms will swing through in one quick burst with the front. The only reason the timeline for storms is so wide is to capture the variability in timing, not the duration of storminess.

WHO SEES WHAT DURING THE STORMS?
EVERYONE — Breezy conditions, brief heavy rain, lightning, wind gusts up to 35mph
SOME AREAS — Breezy conditions, brief heavy rain, lightning, wind gusts up to 45mph
FEW PEOPLE — Breezy conditions, one extended round of Heavy rain, brief localized flash flooding, frequent lightning, wind gusts up to 60mph, small hail
VERY FEW SPOTS — Breezy conditions, very heavy rain, brief localized flash flooding, frequent lightning, wind gusts up to 70mph, hail up to the size of quarters, the chance for a tornado (up to EF-3 in strength)

Once the front does pass, it will still be a bit breezy, but the weather should get back to being mostly sunny by afternoon. Then the weekend looks great.
