Today in Alabama will be another dry day, with partly to mostly sunny skies and temperatures climbing into the 70s. Clouds will increase overnight as a surface front approaches, bringing a chance of showers and thunderstorms tomorrow.
High-resolution models indicate the main rain chance during the day will be across the southern two-thirds of Alabama, generally south of Interstate 20. Tomorrow night, a band of showers—and possibly a thunderstorm—will advance into the Tennessee Valley as the front moves southward.
The Storm Prediction Center (SPC) has issued a low-end “marginal risk” (level 1 out of 5) for severe thunderstorms across most of Alabama tomorrow. However, the severe weather threat appears limited due to weak atmospheric instability and dynamics.
Saturday and Saturday night will be mostly dry across Alabama, though a few isolated showers cannot be ruled out. Temperatures will remain mild in the 70s, with a mix of sun and clouds.
An Arctic cold front will sweep through early Sunday. Ahead of it, a few showers and a thunderstorm could occur late Saturday night into early Sunday morning. Despite this, rain amounts are expected to be light and spotty due to limited moisture.
After the front passes, a brisk north wind will develop Sunday, causing temperatures to fall across the northern half of the state. Sunday afternoon highs will range from the mid to upper 40s near the Tennessee border to the low 70s in far South Alabama.
“SPC has defined a low end ‘marginal risk’ (level 1/5) of severe thunderstorms for most of Alabama tomorrow, but the overall severe weather threat looks low with limited instability and weak dynamics.”
Author's summary: Alabama sees a dry day today, with showers and storms returning tomorrow mainly in southern areas, followed by a cold front bringing cooler temperatures Sunday.
