Area Forecast Discussions are the real forecasts, written 3 to 4 times daily by NWS meteorologists reading the models and interpreting what they mean for your area. They offer far deeper insight than any weather app, but they're written in dense meteorological shorthand. Plaincast uses Anthropic's Claude to summarize them into plain English, side by side with the annotated original.
Plaincast decodes the National Weather Service's Area Forecast Discussion — the real forecast, written 3 to 4 times a day by the meteorologist on shift — into plain English. The discussion is where a forecaster explains their reasoning: which models disagree, what they are watching, and how confident they are. Below is the current edition for Birmingham, with its shorthand expanded. The full experience — an AI plain-English summary beside the annotated original — loads with JavaScript, and every one of the 68 forecast offices has its own edition.
Heat: Minor to moderate heat risk will continue through the upcoming week. Heat indices are forecast to remain below 105 degrees.
Storms: There is a Marginal Risk (Level 1 out of 5) for severe storms across southern portions of Alabama both today and Monday. Damaging wind gusts are the primary threat.
(This afternoon through Saturday) Issued at 1242 PM CDT SUN AUG 23 2026
Water vapor imagery this morning reveals an upper level trough lifting across the northeast as an upper level ridge expands out to our west. At the surface, a cold front can be analyzed draped across the southern half of the state. This boundary is likely to linger close to the northern Gulf coast for the next couple of days. Meanwhile, a few impulses will rotate through the northwest flow aloft, helping to trigger a few bouts of convection, generally during the afternoon and evening hours. Greatest chances for convection through mid week will be to the south of the boundary as a moisture convergence axis becomes established. Drier air filtering in across our northern areas will help keep rain chances at bay. To the south of the front, ample instability, high DCAPE and mid-level dry air will continue to promote a risk for damaging wind gusts with any storm. Therefore, SPC maintains a Marginal Risk (Level 1 out of 5) for severe storms across the southern half of the state through Tuesday.
By mid week, another upper trough deepens across the Great Lakes region while sending a cold front into Central Alabama sometime Thursday into Friday. As a result, we will see low to moderate (30-60%) chances for showers and storms at times through the work week.
High temperatures this weekend will settle into the low to mid 90s for most. Drier air will help keep heat indices in check, generally 95-102 degrees. Increasing rain chances and cloud cover next week will help trim off a few degrees with highs in the upper 80s at times. Continued humid conditions will warrant a moderate heat risk for most through the next week.
