Birmingham is preparing for a weekend marked by rain and thunderstorms, as indicated by the National Weather Service's latest advisory. A frontal system is set to move through the region, increasing moisture and atmospheric instability, leading to the development of thunderstorms across the area. The storms are expected to commence late Friday night and continue through Sunday, with Saturday afternoon anticipated to be the period of the most intense weather activity. Residents should anticipate heavy rainfall, with potential accumulations of up to 2 inches in some locations, which could lead to localized flooding, particularly in areas with inadequate drainage.
