James Spann: Mix of sun, storms for Alabama this weekend

RADAR CHECK: We have a number of showers and storms on radar this afternoon that are scattered and random, and moving slowly to the east/northeast. We will maintain the chance of showers and storms through the evening; they will wind down later tonight.

THE WEEKEND: No real change. Warm, humid weather continues Saturday and Sunday with a mix of sun and clouds, and we will have scattered showers and thunderstorms around, mostly during the afternoon and evening hours.

There are many big outdoor events across Alabama this weekend. This is what you can expect:

  • The storms will still tend to be rather random and scattered, meaning rain distribution will be uneven. Some places will see heavy rain, others not that much.
  • It is impossible to tell you exactly when and where storms will develop far in advance; you just have to keep an eye on radar trends. Most of the showers and storms will come from 1 until 10 p.m., but we can’t rule out the chance of a late-night or morning shower.
  • The sun will be out at times, and afternoon highs will be in the 80s.
  • No organized severe thunderstorms are expected, but a few “pulse” type severe storms are possible with gusty winds and small hail.
  • Heavier storms will produce a good bit of lightning; when thunder roars, get indoors. For those who are in charge of outdoor events, if there is lightning within eight miles, everyone has to get inside, or into a vehicle.

NEXT WEEK: There will be no real change in the air mass, so the weather pretty much stays the same all week. The sun will be out at times, and we will have scattered showers and storms daily, mostly during the peak of the daytime heating process. Highs will be mostly in the 80s.

EARLY SEASON TROPICAL MISCHIEF? Both global models continue to suggest a tropical low will form over the southeast Gulf of Mexico toward the end of next week, about seven days from now. Specific solutions, however, vary. The GFS (American global model) shows the system moving over the Florida Peninsula Saturday, then moving northeast to near Chesapeake Bay by Memorial Day. But the European model pushes the low toward Apalachicola Saturday, and then up into north Georgia by Memorial Day. It is simply too early to know about the impact or track; it’s just something to watch for now. Most likely, the main impact will be east of Alabama.
