Plaincast — the National Weather Service forecast, decoded into plain English
Plaincast
What the forecast actually says — NWS Area Forecast Discussions, decoded into plain English.
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 Charleston SC, 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.
Messages
1) Dry conditions with gusty winds this afternoon.
2) Freeze Watch in effect for early Sunday morning with frost/freeze conditions possible through Monday morning.
This is the plain-text edition, decoded without AI so it loads anywhere. Read the whole Charleston SC discussion at /o/CHS/, see what changed since the last one, or open The National Desk for where the weather is today.
