Sunday could bring not one but two rounds of severe storms to Alabama -- and the second one will really be one to watch.
NOAA’s Storm Prediction Center on Saturday afternoon upgraded part of central and south Alabama to a moderate risk for severe weather on Sunday. A moderate risk is Level 4 out of 5 and means that widespread severe storms will be likely.
Part of Alabama was also under a moderate risk last Sunday (April 12), and there were 24 tornadoes statewide.
Sunday’s storms are expected to come in two rounds. Round one could arrive before daybreak and last into the morning hours and bring winds up to 60 mph and hail the size of golf balls.
Round two, expected later Sunday afternoon, will add in the threat of tornadoes.
The Storm Prediction Center said “numerous” severe storms will be likely on Sunday from Texas all the way to South Carolina. Forecasters added that several strong tornadoes will be possible from Louisiana into Alabama Sunday afternoon and evening, as well as large hail.
The increased concern about tornadoes is what prompted forecasters to upgrade the risk for Alabama.
Both rounds of storms could bring flooding rain, and up to 6 inches will be possible in parts of the state. A flash flood watch has been issued for parts of central and south Alabama in anticipation of this.
The Storm Prediction Center has a large part of Alabama under a risk for severe storms on Sunday.
In addition to the moderate risk for central and south Alabama there will be an enhanced risk, or Level 3 out of 5, for the southern half of Alabama, from roughly Birmingham southward except for coastal areas. An enhanced risk means numerous severe storms will be possible.
Nearly all the rest of Alabama will run the risk of seeing severe storms as well. Only extreme north Alabama may get to avoid the severe weather risk this time around — that area, including Huntsville, Decatur and Florence, as of Saturday afternoon is not in a severe weather risk area for Sunday.
That could change -- and forecasters urged all Alabamians to keep a close eye on the forecast on Sunday in case severe storms are able to make it farther north than anticipated.
Here’s what the weather service is thinking will happen on Sunday. The cold front that is passing through today and bringing rain to parts of Alabama will stall at the coast tonight. Then it is forecast to move back to the north overnight as a warm front.
The front could set off rain and storms through the morning hours, with storms entering west Alabama anywhere between 3 a.m. and 6 a.m. and tracking eastward through the morning.
The strongest storms may end up being confined to areas along and south of Interstate 20 — although that could change — and could bring the threat of heavy rain, damaging winds and large hail.
Then there could be a sort of lull through the late morning and early afternoon hours, which could help the atmosphere prime itself for another round of storms later in the afternoon, according to the weather service.
Forecasters cautioned that there’s still some uncertainty about how the afternoon round of storms plays out.
A cluster of storms could develop in Mississippi and move eastward into Alabama, possibly intensifying as it does, according to the weather service.
It’s possible that supercells could develop ahead of the main cluster of storms as well.
There’s also the question of how far northward the warm front makes it. Areas south of the front will have more unstable air and a better chance for severe storms. Areas north of the front could still see strong storms and also the threat of flooding, especially if multiple storms track over the same areas.
Parts of south and south-central Alabama have the potential to see flooding rain as well, with up to 6 inches possible in some areas on Sunday.
Storms are expected to move out by Monday, and the weather for the first of the week appears to be on the dry side.
However, the weather service is monitoring another chance for rain — and potentially storms — by late Wednesday or Thursday.
