Passing storms for Easter weekend, drier next week: Southern MS/AL/LA Weather Forecast – 4/15/22

Not a bad day today with a few storms possible, but showers and storms are back in the forecast as we move through the weekend, but these storms won’t be as potent as the last few rounds and won’t be as widespread, either.

Both Saturday and Sunday will feature chances for rain and storms, and that may leave any outdoor activities a bit soggy. Plus, if storms are nearby you may have to watch out for lightning, gusty wind, and small hail, too.

Storms on Saturday will not be moving the typical direction for Spring storms, so that may be one thing to keep in mind. Storms on Saturday will be moving from Northwest to Southeast. Normally storms move from Southwest to Northeast.

This change in direction means that the potential for certain types of severe weather will be higher while others will be lower.

For example, on Saturday (and Sunday) the threat for hail will be a bit higher. It doesn’t mean hail will be bigger, necessarily, but it means that the way the storms are going to be oriented will be more conducive to producing hailstones that fall to the ground without melting first.

Conversely, the tornado threat will be a bit lower. Storms that move from northwest to southeast in this part of the country have a much more difficult time producing tornadoes due to how the orientation of storm inflow winds are relative to the rain shield and upper-level wind.

Doesn’t mean it is impossible, just means it is more difficult.

Sunday will feature storms that are probably a bit later in the day and a bit more isolated. But the same rules apply. Storms will be moving from Northwest to Southeast and the threat for severe weather will be there, but it will also feature a lower-than-typical tornado threat.

The two above images are a look at what the atmosphere will look like on Sunday evening. A few isolated-to-scattered storms, with the potential to turn severe weather the main concerns being heavy rain, lightning, gusty wind and small hail. The tornado threat would be pretty low, though not totally zero.

If you have any outdoor activities on Sunday morning, the computer mdoels keep most of the rain across parts of northern Mississippi and Alabama.

That may change during the next 24-36 hours. I have a sneaking suspicion that the storms on Saturday are going to dictate where the storms on Sunday erupt due to lingering outflow boundaries and other mesoscale perturbations that may linger in the region after the storms move through Saturday evening.

After that point, things clear out for next week and – so far – there is no chance for severe weather next week. Hopefully that holds. I know many of us are tired of “Wild Weather Wednesdays” for sure.
