South Mississippi Forecast 5/28/21: Memorial Day weekend starts soggy, ends dry

Looking over the latest data this morning, it shows the front on the way and showing up about midday today with showers and thunderstorms zipping across the area between 11am and 4pm.

The HRRR model shown above it probably a bit too dry and doesn’t develop enough coverage along the front as it passes, but I do think it has the timing correct. As storms pass, most of the stronger storms may feature some heavy rain, plenty of lightning, wind gusts up to 45mph, and small hail. While a tornado can’t be completely ruled out, this isn’t the type of setup that produces significant tornadoes.

The SPC has tagged the area with a Marginal Risk for severe weather, but only one or two storms will get to this strength. And even that feels like a bit of a stretch. The main concern with any severe storm is going to be storms that have wind gusts up to 60mph.

That sets the stage for a much drier weekend – both from precipitation and humidity! Take a look at these dewpoints in the coming days. We go from the 70s today (rather humid) to the 50s by Sunday (rather nice)

And if you are lucky enough to have Monday off, too, it will be a nice day across the area with lower humidity, too. In fact, the Heat Index (when we add Temperature and Humidity to give a ‘feels like’ temperature) on Monday will be in the 70s and 80s.

And we don’t ahve to earn it with any rain! Take a look at the forecast sounding. Usually, when we are talking about rainfall, the green and red lines are really close together on this chart.

Look how far apart they are!

One thought on “South Mississippi Forecast 5/28/21: Memorial Day weekend starts soggy, ends dry

  1. Just the scenario I was hoping for for this weekend and Memorial Day. Everyone should have Monday off. In ‘my’ opinion, any business that doesn’t close for such an important day should really take an inventory of themselves.
