South Mississippi Forecast 7/1/21

Things are still looking humid and rainy. No change there. The late-season front that will try to get to the Gulf Coast is unlikely to survive all the way down. So far it looks like data suggests it will wash out somewhere between I-40 and I-20 as it is barreling south.

Is there a chance it gets to I-10? Sure. There is a chance. But the air will be heavily modified by then.

Looking at the data for Saturday evening across four different forecast models, most have the drier air (in green) hang up north of I-20 while the very humid air (purple) is shunted back to about I-10.

By Sunday, Independence Day, with enough sunshine and vertical mixing, there is a chance that if you live closer to I-20 you are able to get some relief.

But I wouldn’t bet the farm. These late-season fronts rarely have enough ‘umph’ to make a serious dent. We saw one of these last year around this time. And it was great! But getting one on back-to-back years is like predicting a 6″ snowfall in South Mississippi on back-to-back years – and you won’t ever see me do that.

Oh, and Tropical Storm Elsa is now a thing.

  1. As I indicated yesterday, you may want to confer with your former co-workers at WDAM. They’re still showing, as of this morning, the front making it all the way to the coast … showing just a 30% chance of precip on Sunday instead of 50 or 60 percent. It will be interesting to see what measures out.

    1. Yeah, I mean, there is data to support such an outcome. But I would rather be wrong by not forecasting a once-in-a-30-year event to happen… As opposed to forecasting a once-in-a-30-year event to happen, and then it doesn’t happen.

      Just a difference in forecasting style, I suppose.

      And I’ve been wrong before and I will be wrong again. But experience has taught me to be very skeptical of these types of events.
