Through late Sunday morning, a frontal boundary will continue to lurk in the vicinity of the Tennessee Valley, and it is the same boundary that sparked up numerous strong to severe thunderstorms on Friday and Saturday, including the EF-2 tornado that occurred in Jones Chapel within northwest Cullman County Friday evening.
That frontal systemwill start to lift northward on Sunday. Waves of showers and storms will still develop along the front as it drifts north, and some of those storms could make it into the the Valley Sunday afternoon. Areas farther north, mainly Southern Tennessee, are the most likely to see more storms today. As the system moves shifts to the north, the higher threat for severe weather will also shift to the north.
Much of North Alabama will stay mainly dry Sunday, but in the event that an isolated storm is nearby, you can stay ahead of the storms with Live Alert 19 which features our interactive radar as well as live alerts regarding nearby rain or lightning. Any storms that do develop could get heavy with frequent lightning, small hail, and high wind gusts.
With fewer storms around it’s going to get hotter today! Temperatures will try for 90°F this afternoon with a ‘feels like’ temperatures in the upper 90s. The heat and humidity that starts building in Sunday is just a taste of what’s to come the rest of the week too.
Hotter temperatures and slightly drier weather returns!
Saturday’s frontal boundary has since lifted to the north, which means warm, humid air continues to flow into the region. Without a cold front to sweep out the humidity or a strong ridge to suppress afternoon storms, each day will have at least a chance of a few spotty downpours next week, but we do not anticipate the storm coverage to be nearly as widespread compared to the past several days.
We are anticipating an upper level ridge to build in the center of the country next week, which will help to suppress much of the thunderstorm activity over north Alabama and southern middle Tennessee. A stray shower cannot be ruled out, but otherwise expect hot and dry conditions Monday through Friday of next week!
Temperature-wise, daytime highs will creep back into the low to mid 90s, and overnight lows will remain in the upper 60s to low 70s. Isolated showers (10-20%) may pop up in the afternoon before fizzling out before sunset.
