South Mississippi forecast 6/1/21: Welcome to Hurricane Season

Welcome to Hurricane Season. Coincidentally, this year, it is also the start to out ‘there is a chance for rain every afternoon’ season, too.

It looks like, as anticipated, one ridge of high pressure has moved out leaving the door open for much more humid air to be shoved into the region. It won’t be felt immediately, but the last few days, we have been able to ‘mix down’ some drier air as the daytime heat drives the humid air at the surface up.

But during the day today, the drier low-level and mid-level air will be replaced by humid air, which means we will be mixing down air that is just as humid. So we won’t be able to enjoy the afternoon sun as much anymore.



And at the surface, with high pressure setting up to our southeast, we will start to build in air from the Gulf and Caribbean. Also, much more humid.

With an area of low pressure developing to the west, this will set the stage for afternoon storms to return. Almost every day.

All the while, not that we are in Hurricane Season, we will have to keep tabs on what may by brewing in the Tropics. So far, it looks like things will remain pretty quiet during the next five days, but once we get into the Day 9 – Day 15 timeframe, things look like we may see something try to develop near (or in) the Gulf.

Remember, NOAA and Colorado State meteorologists are forecasting an above average season. So please keep tabs on the Tropical Forecast! And don’t go more than a few days this summer without checking in to make sure something ‘new’ hasn’t popped up.

The Bottom Line

It is going to be a generally soggy few days. Today may not be quite as bad with a lower chance for rain, but as we move through the week and through next weekend, a few little areas of low pressure to the west and a ridge to the southeast means continued chances for afternoon storms.

So far, the rainfall totals during the next seven days don’t look to top 2″ to 4″ across the area. So while it will be soggy, it doesn’t look like it will be a complete washout and flooding doesn’t look to be a concern at this time.

Just keep the umbrella handy. And if you have any outdoor plans, keep an eye to the sky and when thunder roars, head indoors!
