Plaincast — the National Weather Service forecast, 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 Grand Rapids, 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.

Lake effect showers into the weekend then dry and milder

The Great Lakes region is between an upper low across the NE CONUS and a sharp upper ridge to the west as an omega block is in place across North America. The resulting cyclonic flow will continue through Saturday before the blocking breaks down and heights rise by Sunday.

Lake effect rain and snow showers will gradually end this weekend as the ridge flattens and moves east across the region, with dry and mild conditions into mid-week. Return flow moisture and a low moving across southern Canada could being showers by the end of the week.
